1st- is the casting of the tsx k24 head the same as the k20a2?

2nd are the gear ratios in the k24 (tsx) 6spd the same as the k20a2, if not could somone give me the specs and the final drive.

The reason i'm asking is it may be cheaper for me to buy the complete tsx swap from a wrecking yard, oppose to piecing together the block, head, tranny, sensors, etc. If im removing all the internals anyways. Correct me if im wrong.

I have a very specific goal and the budget is going to be stretched very thin as is, so any input on where to get solid deals or who may have hooks that would be willing to share would be greatly appreciated, either way thankyou for your time.

NO - see & read thread titled TSX swap a few threads down - there are more complications then just the head being a slightly different casting

2nd are the gear ratios in the k24 (tsx) 6spd the same as the k20a2, if not could somone give me the specs and the final drive.

no they are NOT the same

------TSX--------pre'05 RSX-S--------05+ RSX-S--------Type R
1----3.267-----------3.267--------------3.267--------------3.267
2----1.880-----------2.130--------------2.130--------------2.130
3----1.355-----------1.517--------------1.517--------------1.517
4----1.028-----------1.147--------------1.147--------------1.212
5-----.825------------.921---------------.921---------------.972
6-----.659------------.738---------------.738---------------.780
FD--4.700-----------4.386--------------4.764--------------4.764

EDIT post edited to show correct FD #'s guess I shouldn't have posted because I was slightly off on the FD # for RSX-S & TSX

No, but there's more to this question, what do you want to accomplish?

2nd are the gear ratios in the k24 (tsx) 6spd the same as the k20a2, if not could somone give me the specs and the final drive.

No, they're like this:

tsx RSX-S
3.267 3.267
1.88 2.13
1.355 1.517
1.028 1.147
0.825 0.921
0.659 0.738
4.7 4.389

And they mount differently too.

I also beleive I remember the Hondata guys saying the TSX has half the amount of VTC adjustment aswell, SO might have less piston-valve or valve to valve clearance....

 

[kennethNA]

Thankyou for the responses. Like i said in the earlier posts. I thought it may be possible to just use the complete tsx swap as a building point for an allmotor application. But it never fails that its always more complicated than that. So at this point it looks like a A2 head with the k24 block and still learning about which tranny application suites my needs best. Brian, I was at sema and i was able to take a long look at the crx on display. Looks like its gonna be tight, But i guess you cant have your cake and eat it too. The reps were very nice and considerably patient considering the q's people were asking. Either way I'll need a set from you soon.

 

[kennethNA]

Here's my goal, Beyond the pain of swapping mounts, engine management, etc, i wanted to figure out what platform best suites my goal. k24 block( you guys give me your suggestions on whitch-tsx,crv. k20a2 head or k24a. Transmission can go either way, going to replace diff with a spool either way. So back to goal- 95mm crank, 89-91.5mm bore, 14.5-16.1 comp. Obviously head reworked, alaniz-is a little hesitant, endyn, portflow etc. Key, up for suggestions, still hunting for best valve train, cams, throttlebody, manifold, it seems to never end. Anyways I know my thought is all over the place so i apologize in advance. Please feel free to give all ideas. I would like to hear from pacman, nikos, k20eg, brian, and charles or norris but im sure there too busy with there own issues.

Bye the way, this post is not some random dream, im hungry in all seriousnes so please approach it that way. Thankyou in advance, kenneth.

 

[nikos]

I do understand what you are asking but I am still confused about your goals...

95mm crank, 89-91.5mm bore, 14.5-16.1 comp

what kind of power you would be happy with?

Is this just for drag?

I mean we saw both norris and Dr Charles go high nines with their k motors all motor, but there is some serious $$ in these projects. Not to mention the amount of r&d. I am confident that these 2 cars will go all out next year. Skunk of course does their own work. Norris car I believe gets their engine work done at rddyno

Check out their stroker kits... http://www.rddyno.com/index.php?cPath=32_93

my GOAL

Goal- 380-400 whp/ 230-270trq

To be competitive with or faster than the leaders in the all motor class.

If saul can run 10's in a all motor street class h22/crx than i should have very little problems running 9's in a properly prepped crx like bisi or durst , except with the k powerplant. I know the #'s skunk and norris make. And im really not impressed. Are they better than the b series, yah, for the most part. Bisi still makes more power. But charles and norris know there is so much more untapped potential. This is my Opinion. So Goal, be stupid fast! I'm just not super knowledgable about the kseries even theough I do countless hours of research. In time i guess.

Re: my GOAL

Goal- 380-400 whp/ 230-270trq

-ken-

I would aim for 300 ehp & 200 tq first...once you hit that then aim higher

 

[kennethNA]

I have 3 friends personally that are just under 300hp daily driven, 1 of the 3 just dynoed 307 at chuches place, dyno was adjusted. So in my head up to 350-60 is pretty self explanitory. Here's the dilema, you get over 300 easy persay, then you just tear it down all over again and completely rebuild to go after your goal. I wanna go all out the first time around so i don't kill my budget. Can you feel me. Thanks for the comment though.

 

[nikos]

Damn... so in all serioiusness, you need to give us some pointers...

Tell me, what should we look for when sleeving a k24a block? Which rods are the best? Which crank?> Golden eagle? Darton? Someone else?

What do they use?>

ANy advice on head internals? Block internals? Pistons?

Here;s a cool up close shot of the skunk2 monster.

Well at least i got your attention. Ive seen way too many pics of this setup and CM car. Problem is pics don't do a whole lot. I could be wrong but i feel a little sceptisism in your post. But here's what my friend has with over 300 to the wheelies! Crv block from SD junkyard, k20a2 head, JDM tranny from his buddy kWat. Head to my knowledge consist of supertech valvetrane, crower custom camshafts, cant remeber duration but i believe the lift is int 12.8 ext 12.2, he opened up his own manifold and runners. Custom throttlebody. Alaniz head which was very mild because he claims its easy to create loss if your not careful. 3 angle valve job. milled 15k. Darton sleeves in a benson assembled bottom end. Crower BILLET crank, 95mm, cp pistons 89.5, comp was stupid low 12.5 i believe. kpro. msd. True daily driver, and he feels #'s are very, very low. He thought 335-350 easy. but goes to show. This is why i thought maybe i could get some ideas or insight from u guys. my friends dont really play on forums, there old school garage and shop junkies. There motto is "don't talk about it, BE about it". But since I'm not real knowledgalble once again I try to do a little research.

 

[kennethNA]

oh forgot crower titanium rods, not sure length or pisition of pins. sorry so vague, I'll get specifics from him tom. I'm actually supposed to race him on my bike tom, heads up, he's gonna be on 25-9-15, vht, should be interesting. car weight is 1836pnds in a 92 cx, with some lexan. still daily driven. May get video footage.

 

[nikos]

hey kenneth,

I saw the fully built h22a you have for sale.. That setup is sick!!!

 

[kennethNA]

hey kenneth,

Aww thanks, im trying to be like you and my friends. I'm actually an all motor whore. Hence why im always here trying to gain knowledge. You would love it out here. " So Cal" so many street races for good money. I have now seen 2 k series eg's beat very high horespower turbo cars. Pretty amazing sight. Gets me all excited. But my budget may only permit me to race on the track, at least for now :twisted:

 

[JDM2ndGen]

sorry to jack your thread ...but ive been tring to search from some info on what motor is more suited for drag k24a, k20a or a K20a2 ...or k24 block with a k20a head ...i do plan on doing a full build but my budget wont permit that right now lol ...so ill prob only have ITB's DTR header Kpro ...

so if you could shed some light on this for me and maybe point out the pro's and cons of each motor it would be greatly appreciated ...thanks

and again sorry to jack your thread ... :up:

 

[Teg]

I 2 would like to know.

 

[95EG20A]

Nice motto your freinds have but find out what to do before doing it saves you money big time in the end! Pleople find out what works and what doesn't by making mistakes that breaks there bank finding out some info from people already know is priceless, I just last week purchased my first k motor and am planing to do my swap into a 95 coupe that's why I looked and found a knowledgable forum to get help w/some extra h.p.!!! ONLINE HELP ON FORUMS RULES!!!!!!

Not to be a hater or anything, but where did you get the sleeves from Darton?? Just asking cause last I heard from Rob and John at Darton, K24 sleeves were not available yet. In fact, They were still waiting to recieve shipment of a k24 block to use as their model. As of 2/17/04 K24 sleeves from Darton were still 8 weeks out. But mayber your buddy got the
prototypes.......

EDIT: Also, what kind of suspension is your buddy running? IMO 330-350 all motor HP on street tires is worthless. So unless there is some new compound street tire I dont know about....

 

[- guest -]

You're probably referring to their MID application sleeves, of which they have not released the K24 application. Darton also makes universal blanks that can be fitted. That's what I did for my first K24 block over 2.5 years ago and is most likely the case for all other K24 darton sleeved blocks out there done by various authorized darton machine shops.
