Unit2Fab or any aftermarket steel oil pan inferior or?

I recently picked up a Unit2Fab steel pan as I was looking for a baffled oil pan as well as a turbo drain and oil temp sensor bungs.

not really wanting to spend the $ on the aluminum versions. Also figured other than possible slight heat difference could not see any cons?
But
I realized that my oem oil pan (DC5 Type S) ties in the transmission and possibly makes the engine/ transmission tie in stronger and more stable because of this. So am I overthinking it or is the oem pan better and creates a stronger tie in that really matters??

Next question is I don’t really want to have to unnecessarily drop my oil pan for any maintenance, are these baffled trap doors something I have to be concerned about causing any issues in the long run? I’ve read of skunk2 ones getting stuck and causing oil pressure drops?? 😳 also even read of one causing catastrophic damage to engine because of this.

those flukes or something I actually need to be concerned about. Wondering if I should just bung my oem pan and just install a trap door less baffle like Circuit Hero or similar? I mean I don’t race. While I may track my car it’s not a regular thing. Once in a blue moon for fun. I just like the idea of having extra protection when I do slam some windy mountain roads now and then and when I do track my car. For peace of mind. I already got my ubit2fab pan but didn’t install it yet. I never researched before getting it and my fault but I just never thought there could be negatives and they assured me I’m good but of course they would right?

Thoughts?

Better to have it and not need it. The Unit2 pans with trap doors are superior over the factory pans as far as holding oil pressure goes. At the end of the day, having an oil pressure sensor or switch for safety can really extend engine life if you run in to issues as well.
 
#3 ·
Yes that was my train of thought. Just wondering 2 things 1) if the trap doors could ever cause an issue? 2) does losing the additional bracing and tie in points of the transmission bell housing makes a realistic difference in strength? Losing 2 bolt in points of the bottom of the bell housing seems like a big deal? I imagine a lot of people are racing with aftermarket oil pans without the lower tie in bolts so I imagine it’s fine ? However I’d imagine Honda did that for a reason on the Type S?

My trans isn’t bolted up at moment so I screenshotted these pics from an old post here to show what I mean. Mine has these tie in points. The bottom of bell housing bolts to it.

with my Unit2Fab pan below, I’d lose this. There is no provisions so the bell housing wouldn’t be bolted to anything at almost the lower 40% of the bell housing. I never paid attention I guess and didn’t even realize this until I was near installing the oil pan. Evidently no aftermarket pan from what I see has these tie in points also so I’m assuming it’s fine BUT why would Honda go this extra mile on the Type S if it doesn’t matter? 🤔. I’m also going boost so adding 160-200 whp I’m sure wouldn’t help the cause also? Perhaps I’m just overthinking it but I am anal about my cars and generally look to “upgrade” not “downgrade” performance wise anyway.

i know it will be “fine” this isn’t a race car but if and when I do take it to the track it, yes it’s just for fun but I will be pushing it to compete against my own times and buddy’s times haha for bragging rights so I want what’s best in track conditions even though it’s not a dedicated track car If that makes sense.

I am debating just installing a baffle and bunging my oem pan now just because of not liking the idea is the bottom of the bell housing just seemingly “hanging” there. I know not literally but just exaggerating my point lol.

Would you know if Circuit Hero’s billet baffle and Junk2 I mean Skunk2 also are Copies of Clockwise Motions baffle??? They look suspiciously similar to Clockwise Motion’s baffle 🤔

I’m a strong believer in supporting the original and even though it’s a good bit more I’d rather buy from Clockwise Motion, I tried to check out but it won’t give me any shipping options to USA.
I will try to contact them.
Oddly I heard of a couple of catastrophic failures of Skunks version, trap door getting stuck or something like that resulting in oil pressure drop spikes and ended up in catastrophic damage. If so, design flaw or just wasn’t a good job copying an excellent design?? They couldn’t even copy it right?? LOL

I haven’t seen anything bad about Circuit Hero’s version.

actually maybe their basic version is fine for me as it will be quite rare I track my car. Looks like Spoon and Toda, J’s baffles all don’t even have trap doors. I wonder if I want to set it and forget it that actually this may be the way to go for me 🤔

I don’t want to worry about trap doors getting stuck etc. looks like a ton of moving and small parts on the Clockwise baffle, no?

I agee. Manufacturers don't do things for no good reason. This falls under structural integrity. It's EZ enough to weld in a bung that is cheap and readily available. then mod the factory pan. Probably save some money and an aluminum pan is better than steel in my opinion. Keeping in mind the extra hoepower. There's been some write ups in here on this.
 
#11 ·
My oil pan position is totally fine. It sits above the subframe so no threat of hitting it. Looks like I will stay with my oem oil pan, look into having drain bung welded and will just run my oil temp sensor somewhere else. While I have the oil pan off I may as well put in a baffle so I have to decide on which.
 
#8 ·
Man and paired with the “wings” the alloy pan has that ties into the bell housing it would be even more “as one”. I wish I researched better. I got the Unit2Fab pan all powder coated up and pretty too haha.

I guess I’ll sell the unit2fab pan , order a baffle and just modify my pan for turbo drain.

Thanks guys 👍

Thanks guys 👍
We're not done yet, don't go selling it. There's more meat on this bone!
if your oil pan ends rather low in the engine bay and there is the danger of banging it on the ground, a steel pan offers that ductility. It bends upon impact while the alloy pan cracks open.
I'm gonna have my mom start commenting if you keep it up. SO that cold easily take out the pickup or otherwise bang the traps up inpaeding oilflow all the same. BESIDES in an RSX it does not hang down to that point. Beides You would rip your front end off first. Don't micro manage me Man!
Just messing with you, it could happen. But I only know who my dad is cuz my mom told me?

EDIT!: you got in right before me. In your case I'd just add an extra quart of oil and sleep well. Your gonna piss yourself off, trust me.

Haha, I know this shouldn’t be that hard of a decision. So what you’re saying is not even to do a baffle? Just run some extra oil?
In that case doing a simple baffle like Circuit Hero’s version 1 should be fine?
I mean while I have the oil pan off and having the oil drain bung welded I’m down to put in a baffle that would help keep oil near sump even tho I may not need a trap door version. I’m down for it if it can help but not harm.

my Unit2Fab steel pan , I’ll wait until I am 100% before I sell it just in case LOL. I am tempted to just put it in and take my time on modding my oem pan too. In all honestly it would be fine also as I don’t hammer my car and If I do I don’t believe the track I’d take it too has high speed super long turns that would be more than a few seconds anyway. So any way I do it probably be totally fine. I just want to feel right about my decision, too many times I settle and it annoys me so I’ll take my time and decide.

I am leaning toward having drain bung welded in oem pan and putting in an upgraded baffle that will be worry free.
If Clockwise Motion is maintenance free and no worries about it ever failing somehow then I’ll get over spending the $ part of it if it is that sweet.

That's what I was just say'n. Sometimes you shouldn,t listen to him cuz he's out to get me.

EDIT!: You could try this? View attachment 123060

View attachment 123061
Yes that is exactly what I’m doing for the feed line and oil pressure sending unit if it fits. My Autometer sending unit is huge lol.
I also have a Blitz sandwich plate I can use. I just wanted to keep it as minimal as possible which is why I liked the idea of putting my oil temp sending unit to move one sending unit away in oil pan bung I had Unit2Fab put in on that pan I may end up not using LOL.

edit: shoot I didn’t even look at second pic good until just now, yah so it being so tight in that area I was concerned in what I’d be able to fit. I just have the adapter loosely there and Get to it later but why didn’t I think of adding the other one to it !??? Haha. I actually have 2 of those and even 3 maybe. One is steel, one is stainless steel , one has multiple 1/8 npt , other has just one ☝. On the side too so room is a factor. Never use it down on me to add one on for whatever reason. Sometimes great ideas can be right under your nose LMAO. thank you for that!!

so now back to figuring out what imma do about shiny nice new Unit2Fab pan that I might not even put in and oem pan va baffle situation 🤔 lmfao Did I mention I’m anal about this car? It’s my pride and joy , reliving my childhood dream & want to cut zero corners on whatever I do to it. As some of the parts I have on it expresses 🤣. Yah I over spent on some parts but no regrets is the trade off for me on this. I can cut corners on my old daily 4Runner haha. My 4th gen Teg and Runner tho get the best I can afford that way I don’t second guess if I didn’t get better because I couldn’t afford it and had no choice haha

I've been running my Unit 2 pan on track for 3 years now, the steel one with baffles. If the original aluminum pan was adding stiffness, I'm not noticing it missing. I'm gonna go on a limb and assume those little M6 bolts aren't doing a ton. Surely something, but not a lot. I do have an EG, and the low pan is a real issue in my case. I pulled it and added a temp sender to it this year, but it has otherwise been solid and solved my oil pressure issues on track.
 
#16 ·
That is reassuring and being you track yours all the more I shouldn’t need to worry about it.

although yes it is m6 bolts but it is a bunch of them & would add a lot of strength. The 2 bolts that the bell housing bolts to the oem oil pan are M10x1.25 head bolts though if those where the ones you were referring too.
Basically going with steel oil pan I lose the tie in of two M10x1.25 bolts at bottom of the bell housing. Tied to the oil pan that is bolted to the engine with yes m6 bolts but 15+ of them I have to imagine would add quite a bit of bracing to the transmission.
With that said though the base model and many others don’t use that either so maybe I’m just overthinking it. I still might just do it. It’s not like it’s irreversible or anything, just a little bit of a pain if I decided I wanted to switch back oil pans so I guess I just have to decide amongst myself whether it would bug me or if I’ll get over it haha. I’m sure in my case it would matter Zero. I don’t even realize this going in so what I didn’t know won’t hurt, but now I know dammit 🤔 decisions. Lmao (unit2fab pan sure lookin pretty!)
 
#18 ·
No problem. It's a solid piece. You might feel that loss in strength if you're building a 700hp monster, but there are tons of cars running happily without them.

I was losing oil pressure in the carousel at Nelson Ledges with 200 treadwear tires. It doesn't take a ton, but isn't something a street driven car is likely to see.
 
#19 · (Edited)
Gotcha, right on thanks! I’d imagine even in the mountains wouldn’t see or be safe to do anything that would bring that into play I guess but I like the idea of baffle to not have to worry about it. Also while it may be rare that I do track it, when I do I also wouldn’t want to have to worry about it although I do monitor my oil pressure and temps so if it’s not something that would be a sudden catastrophic failure then I’m sure I’d catch it and let off. I’d be watching my oil temp gauge (edit: oil pressure I mean!) like a hawk in long hard turns haha.
 
#21 · (Edited)
it's important to monitor these things? We're getting off track here. Gotovato will be interested in your oil pan. We've been over the sandwich wars and some of these guy's have so many oil plates there filter is against the fire wall and they can't get it off. Dude you may cause more problems than it's worth? Just keep your pan and get a bung or two.

use lots of Titanium fasteners, this will make you feel better.

Back to this. It can be done! An extra quart in the pan won't hurt. If you want to put a trap in O/K.

What you need to consider is: What are your needs?

See here, I changed my mind.



Still if you look at the factory setup it just ouzes "I love you". Look at it.The webbing and beefyness of it overshadows the bolts it takes to hold it together. Lest we forget the big ass hole your leaving for the clutch to see the light of day and everything else. You should consider some type of cover like maybe from an A3 or something like that? Go with what you know.

I would think about it over some mini muffins though. I like the blueberry ones.
 
#24 · (Edited)
Yah man, either way will work fine for me but I will probably end up with the oem pan either way I go if I know myself.
I do have the the bigger flywheel inspection plate so that part was going to be covered.

Maybe I’ll just do the basic baffle without trapdoors. Save me some $ and still better than oem. Funny thing is I actually had one too, I returned with a restock fee it in favor of getting the Unit2Fab pan lol.

wow I wonder why out of all the aftermarket baffled oil pans other than like Toda and Spoon which just modifies oem doesn’t factor that in?

Warm blueberry muffins sounds good!

yes, although not a track car I still find it important enough to monitor oil pressure and oil temp.

It's good that we can all take a moment? Life is in the details, no. If it takes blueberry muffins to bring us together if even for a moment, life is good. You can run an extra quart it's an road racer trick. I think this is being over thought for what it is. You can weld bungs and add traps. I truly believe Gotovato might be interested in that pan. Where is he?! He can actually use it as he routinely puts it on two wheels. We'll get you get you something going. Did you do a search yet because I know there are weld in products out there and aluminum is easy to weld and repair.
 
#28 ·
Hahaha Can’t go wrong with blueberry muffins!
for sure I’m over thinking no doubt about it. I could basically go any route and be totally fine.
I mean every aftermarket pan, even $900 one’s does not have tie in points even on their aluminum versions and from big companies that are heavy into racing like Moroso, Drag Cartel and etc so the tie in points are a moot point I’m sure. As for the baffle, many race or raced for a while without them also, yep I have read about racers running extra oil too and helped in most situations 👍. I don’t mind throwing in a simple style baffle tho while the pan is out. I don’t plan on removing the pan again until I put in forged pistons and rods hopefully later rather than sooner 😜 that’ll be either when I hit 100k miles or so OR if I break something requiring me to dismantle the engine. Whichever comes first. So putting in a baffle that I probably don’t need, i don’t mind. I have a lot of stuff on my car I don’t need lmao. I rather have it and not need it than need it and not have it train of thought…

Where is Gotovato located? If in UK or Canada it may not be worth the VAT and shipping 🤔 I’m in da US.

I’m tryna underthink it and just put in the Unit2Fab pan , I already have it, it already has drain bung and sensor bung. I already had it powder coated. I’d keep my oem pan and eventually still have a bung welded on and keep it aside in case I ever want to put it back in. If I decide to go this route which is actually now what I’m leaning towards. Unit2Fab assured me it’s a moot point regarding the tie in points. They’re a heck of a lot more knowledgeable and experienced than I’d ever be and they are very reputable so I actually trust their word.

thanks on the gauges ! I dig them, I’m a carbon fiber freakaholic so I had to go with carbon inlay gauges. M
I’m going to add One more now that I decided to Boost, on dash defrost vent mount. A TSG-1 Turbo speed sensor and Boost gauge.

or I may replace my water/coolant temp gauge with it , we shall see. Only reason I don’t run the A pillar mounts is because I have carbon fiber A pillar panels I refuse to remove or modify haha
Did I mention I’m a carbon fiber-holic? 🤣

unt2fab steel baffled pan > anything circuit hero/skunk dropin baffle/Ballade (all CWM copies)/or the blox bolt in baffle (terrible piece btw).

Since you don't really track, all you really need to do is keep your oil topped off.

if you're hung up on the stiffener aspect the aluminum pan provides over the steel pan, you can run this factory K24 block stiffener/brace that fits around a steel pan.
 
#29 ·
Interesting, that particular one doesn’t look like it would work with my trans but I didn’t even know these existed so you have me one more idea to look into, thanks!

I mean I’m coming to the conclusion that that stiffening aspect isn’t really a big deal. Especially since I’m not regularly tracking nor ever will be regularly. Spirited canyon driving and maybe a track session every now and then is it.
I am leaning toward just putting in the Unit2fab pan for now. I will look into those separate braces! If there is one that fits I may do it however not being part of the pan itself doesn’t seem like would really do anything with just a couple of m6 bolts vs the entire pan being one unit so come to think of it probably won’t even bother but I still will look into that! Learn something new everyday, love it

much appreciated Katman
 
#30 ·
I think now is a good time to admit what medications your on? LOL Your ALOT like me, I do things for no good reason other than I can. Hence the titanium and yes....a bit of carbon fiber never hurts?
Still we are faced with a new dilemma it would seem as though Katman has arrived.
This means there's a new sheriff in town?
Oh I know he looks so cute but

trust me buddy, he knows.

I have a semi build thread, you should look at it. There's lots of unnecessary things you can do with your free time.

Like switches to kick on your O2 sensor and other gauges that you should be looking at more than your phone.

Your a stock broker aren't you. That's OK we don't care. You

must over do this and it's not my money so I will continue to talk you through it. Try to take a moment and fix a nice

sausage and veggie dish for that special someone. NO not Katman, he's fine.


look at him, does he look like he cares? NO, he does not. Still he keeps poppin' up. I think he

does it on purpose? About that temp gauge....
Just put one of these on. It will give you a reason to open

your hood and check for whatever. I mean ya know how it is? When you wake up in the middle of the night call me. Unfortunately Gotovato is stuck in Canada and Trump put a warrant out for him. Something about assulting wild animals? IDK
Still....we will be here to work you through this. :alien:
 
#34 ·
Lmao! You’re too funny man, I’ll take some of what you’re having! 🤣

kidding aside yah man certain things I care about and really anal with and certain things not so much. Guns knives and da DC5 get da best I can reasonably afford to put into, all 3 of which has its share of unnecessary titanium and carbon fiber 😜🤣

Yes you could say I’m an investor of sorts, I make a lot of bad investments. Mainly into the aforementioned stuff I catch the fever on HAHAHA!

all good though, it’s my therapy, peaceful, relaxing & clears mind helping escape from the stresses of life stuff when working on & all of the above plus addition of adding smiles per gallon when driving her! Can’t wait till I get er boosted too, that will be a whole new venture in itself dialing in. 👻

I have heard of this happening mainly skunk2 I heard of a couple cases but not many however this was in the back of mind. I believe I will just put in my steel unit2 pan so this is nice to know that it may mot be as much of an issue with steel.
That sandwich block looks slick! However I’d be weary of using that location personally but it does look clean and a slick idea if no potential issue. I’d feel more comfortable with adapter off the block or oil filter sandwich plate myself.

Input & suggestions much appreciated!

regarding the k24 brace @ Moho and Katman I actually browsed a bit I will some more too. That one looks to have holes in totally different areas but if there is a k20 version and reasonable price I’d actually do it even if not needed. It appears to be a flywheel cover / brace for some K24’s

oh I was also thinking about it last night and having the ability to inspect/ clean with that big of a ln inspection window is actually quite nice too. Another pro to the steel pan. Which I believe I’ll end up just putting in. I’ll keep my oem one and if later I feel like I want to swap back I’ll just do so I guess. I’m sure I probably won’t care too after the fact. 😜. I’ll keep oem one anyway tho. I learned my lesson about ridding of things too soon. 👍
 
#37 ·
Your already into the steel pan and unlike myself a couple of reputable people with experience on these have spoken. I'm interested in these stiffeners Katman mentioned. Not that I need them but you might? Your easy going and that's lends to having a good time about it? Life is serious enough buddy. Be sure to keep us in the loop on this! :cool:
