I bought the Del Sol around Feb 2007 as a project vehicle. Was mulling around with the idea of a sleeper. Wasn't looking for a RWD or AWD vehicle. Too much of an advantage there. I didn't want a Civic or Integra as they're far too common. I wanted something known to be slow. Decided upon the "Del Slo". It's getting either a K20Z3 (06 Civic Si) or K24A1 (02+ CRV) engine. K20Z3 is already ready. K24A1 needs to be bored out still and would need the crank pulley, water pump and head from the other engine. Don't really want to crack open a essentially new engine yet though (~60,000 kms).

Car had some front end damage done to it. Removed radiator support to put a brand new, unbent one on. Too poor for one at the moment. Drilled out spot welds.


12.5:1 87.5mm pistons for K24 engine. I think I'll try the K20Z3 first though.


Decided to start on the back end. Removed 4 lug hubs to replace with ITR 5 lugs later on. Trailing arms already set up for disks. Shorter spindle can be used but need a Mazda Protege axle nut.


Part of the bearing was stuck on the spindle on the right side. Using a bearing separator in conjuntion with my puller to get the last piece off.


One upper arm was seized. Had to cut the bolt. Too bad part of the bolt is still stuck in the threaded part. :( Camber kit will need to wait until I get the bolt out or get a new trailing arm.
<Sorry, I'm missing this pic>

Since the rear is jacked up, replacing the ITR suspension on my car with new BC Racing (BC Racing is not Buddy Club) coilovers. Also installing ASR subframe brace and Function7 control arms.


No more need for the previous owner's tie bar!



ASR subframe brace installed for now without the sway bar and brackets.


More to come later.

Thanks all! Unfortunately my build won't be as pretty as some... Can't afford any new paint after losing my job and all. But I'll make it a track car for now. No need to look pretty. :) I've gotta find a new trailing arm unless I can manage to drill out the damaged bolt in my trailing arm. But then I'll need a 10mm x 1.25 tap. Hope my new job works out!

Hey, thanks Mike! Any deals for Canadian customers? ;) I currently have the DC sports header and pairing that up with a K20Z3 for now. But I kinda worry about header clearance when I have the K24 finished. That's on the back burner though. What I like about your guys' budget header is that you've got the 1-4 and 2-3 pairings and works with K24s in an EG/DC chassis.

There were a few other items I was looking at but I think I've just about got everything I need for now.

I'll go make some right now. :D I've been lazy. Plus was trying to figure out how to fix the seized bolt in my trailing arm where it connects to the upper control arm (or camber kit). Had already cut most of the arm out but had to drill a hole through the bolt and go up in size until I could clean it out with a tap. It was kinda tough getting it centered but managed to. :D

Anyway, updates... I'll put my Skunk2 camber kit on shortly. Engine will have to wait until I get my brake lines fixed.

Well, here's my mini-update...

Skunk2 camber kit. Definitely need them now since I had to cut through my stock upper arm.



S2 camber kit installed!!! Also shown are BC Racing (not the same as Buddy Club) coilovers. Bought from HR back before they changed their online store.


Kopr Kote to ensure nothing get seized up. Also good rust protection! Also need to switch to ITR 5 lug setup later on.

Quick update. Tore apart my damaged ITR trailing arms for the hub/bearings. Here's a test fit of my 06-08 Civic EX wheels... Offset seems good! Car originally had fat fives, it'll be going back to fat fives... For a nice updated OEM look. :D


From left to right... K24A1, blown K20A2 block, K20Z3 and in front of blown K20A2 is the K20Z3 tranny converted to work with RSX style cables and shifter.

It's going to be a slow build though... It should perform okay but it's out of my budget now to make it look nice too. :( I got laid off from a really nice paying job. Now I'm trying to learn something new (car sales) and pay my mortgage. :(

are you going to delete the heater hoses? im going with a k20z3 swap myself. and trying to get as much info as possible
For now, yeah. If this ever becomes a daily driver again, I'll have a heater core in place. I ended up gutting the car's interior.

And Texasnick, are you part of the CSCC (Calgary Sports Car Club)? I met a bunch of those guys earlier this week at Stratotech, the track located around Fort Saskatchewan. I didn't drive as my RSX isn't quite track-ready. Running OEM suspension. :( It's too bad about Race City too...

Heh. it's going really slow... Has to do with me being a bit lazy and also having no money. Since I lost my job, I've been broke but have most of the parts. Problem is I wanted to powdercoat certain parts like the knuckles and so on. :(

I'll splurge a bit one of these days to show you all my new suspension. :) I dunno if I'm going to go with the weird FLCA mod that I was contemplating though. Don't have enough $$$ for more control arms. :(

The glow was from a LED flashlight. :) My (Cell phone) camera doesn't have a flash. And I don't have a good camera.

Anyway, not much new. Rear wheels (winter tires for my RSX) are on the ground but no calipers yet. Been busy. :( I want this done too.

Thanks! That's my new years resolution. :)

So, right now, still no real changes. Got the EK steering rack in (just needed two little spacers), 15/16" brake master cylinder, and 5 lug conversion using CRV knuckles, RSX-S hubs, RSX-S front brakes, ITR rears and TSX rotors (required spacing the RSX brakes out 1mm because of additional thickness).

Still have to drop the engine in and do the clutch MC stuff. I'll post pics closer to completion but right now trying to figure out wiring. Want to clean up what's no longer necessary. :)

Thanks guys. My build is going slow because I'm lazy. :) And broke. But mostly lazy.

I'll show you guys a random assortment of pics...

Test of HR shifter.


97-01 CRV knuckle with RSX bearing and RSX-S hub (painted with appliance paint).



Hubs going in here... Along with Skunk2 camber kit.


Test fit of ITR brake booster and MC (later went with EG brake booster and 15/16" MC just so I could use OEM lines)


OEM to Integra Type Rx pedals (pedal covers the same as S2000 and 06+ Si except maybe gas pedal)


Looping power steering lines (this is an ITR steering rack with quicker turn ratio)



These pics are a bit old. I'll grab some new one when my phone gets a bit of a charge.

Still need to do brake lines, brakes (putting piston and seals back in), wiring (adding S2K AP2 cluster), reinstalling the HR shifter, and drop in engine.

New pics coming when phone charged.

Okay, snapped some pics in my freezing cold garage...

K-Tuned traction bar



EG brake booster downgraded from ITR. Didn't want to make new brake lines although I have the tubing, flare nuts and flare tool. Also, shown is how I looped my power steering rack. Just need reservoir now.



HR/Innovative side mount.


K20Z3 with HR side mount and DC header.


Unopened K24A1 ready to be bored out. Also, K20A2 with cracked cylinder from my RSX-S.


Tranny with HR mount.


Tranny code from K20Z3.


5 lug fronts. CRV knuckle with CRV/RSX bearing, RSX-S hub, TSX slotted rotor (ATE PremiumOne), RSX-S caliper brackets pushed out using 1mm washers because TSX rotor is thicker towards outside (washers not shown).



Bench bleeding EF 15/16" brake master cylinder. Also shown is Omni S2000 clutch master cylinder with no reservoir (doesn't come with one).



Interior: DC5 Integra Type R wheel, EK steering column (with spacer circled in red), DC2 Integra Type Rx pedals (pedal covers for gas/clutch available from Honda if you ask for 06 Civic Si pedal covers) and S2000 AP1 seat.






Stuff on top of trunk... DC2 ITR rear brakes, 06 Si (or was it TSX?) shift knob, HR shifter, HR shifter cables



Supertech 12.5:1 CR pistons and unknown K24 rod for future K24A1 build. I'll get to it when I'm willing to crack open the K20Z3. :)


Messy garage... From left to right, K24A1, K20A2 block and K20Z3.


New radiator support with HR/Griffin K-swap full radiator.


06 Civic EX 16" fat five wheels for the stock/sleeper look.



OBX twin loop exhaust.

Damn, all of that just went together? Or did you have to clearance things?
Just have to know what works together. :D Just had to research. I noticed the CRV and RSX used the same sized bearings for example. And also noticed the 2nd gen CRV used the same hub as the RSX-S. I had a thread where I compared the 1st gen CRV hub with an RSX-S hub too somewhere if you want to look for it (1st gen CRV hub was identical except diameter and reason why an RSX rotor would not fit it). :D

Also, looking at BrakeExpert's research, I saw that almost every 5 lug brake upgrade had exactly the same amount machined off the bracket, which lead me to believe most 5 lug calipers are interchangeable on 5 lug setups.

The only mod I had to do was space out my RSX-S bracket (1mm) to use a TSX rotor. Had I used an RSX-S rotor with my RSX-S front brakes, I'd have had no issues. This is because the TSX rotor is thicker by 2 or 3mm towards the outside.

Well, I thought I'd bump this thread and add some notes for myself on what's left to do.

Necessary:
Modify RSX-S axles (swap inners)
Repair cut up ignition switch wiring.
Buy cheap eBay 2.5" piping for Civic HB and have friend or exhaust shop shorten it for Del Sol.
Finish modified Del Sol to S2000 (AP2) cluster harness. This is a need to do as I'm under the impression that the S2000 cluster can convert VSS signal from high to low.
Put S2000 clutch reservoir on Omni S2000 Quicklutch.
Replace brake rubber brake lines with braided lines.
Put piston and seals back onto front brakes and install caliper.
Install radiator support and traction bar.
Double check that all bolts are properly torqued on engine.
Drop engine in.
Lengthen charge harness.
Create new main ground wire from battery to frame.
Modify either the SRS harness or EK cable reel/clock spring because connectors are different.
Install fuel lines and FPR.
Connect engine harness, swap harness and dash harness together.
Hope car starts.

Want to do later:
Replace DC Sports header with K-Tuned 4-2-1 header.
Maybe get a grounding kit.
Remove unnecessary D-series wiring from dash harness.
Repair speaker wiring (cut by previous owner)
Reinstall interior (dash, and other covers)

I never bothered to compare the CRV front knuckle with the Del Sol front knuckle. However, I did compare it with the DC2 ITR front knuckle and it was the same. The rear spindle on my Del Sol Si (already discs) is shorter than the ITR spindle. But using a lower profile Mazda Protege axle nut, the rear ITR bearing and hub bolts right on. Didn't want to use CRV rears as they were drums.

And yeah, it is tough. Luckily I bought 95% of everything I needed before I lost my job. Now I'm living off of roommate money and cash jobs.

Well, looks like I won't be using the Yonaka axles for my Del Sol swap. I tried to swap the inners and it wasn't working. Also, the Yonaka axle lengths were 25" (Driver) and 23" (passenger side). I so wish I could pull them apart as swapping the inners would work great. The new driver side would have been close to the OEM swapped inner's driver side. The new passenger side would have been slightly longer than the OEM swapped inner's passenger side which is slightly too short.

I remeasured my old RSX-S axles. Driver side was roughly 24.5" and the passenger was roughly 22 7/8" (22.875"). Swapping the inners gave me a new driver side axle of 24.25" and passenger side of 23 1/8" (23.125").

It's too bad my old RSX-S axles axles look like ass. All corroded and there's a rip in one of my CV boots. I think it might have happened when I was trying to get the bands off. Looks like I made more work for myself again. :(



Unfortunately, I can't swap the inners on these... I guess I'll keep them for my RSX.

Coming along nice there... Tell me those aren't Canadian tire rotors..:silly:
They are in fact. :D They're ATE PremiumOne's. ATE is also the same company that produces the SuperBlue brake fluid. I had to get TSX ones because they don't make them for the RSX-S (which my calipers are).

If I wanted though, I can always throw on my TSX/CL/TL front calipers on for a perfect fit. Right now, I'm using washers to space the caliper bracket out 1mm or so.

They're not touching my car EVAR! :D But rotors aren't exactly a complex design. I've got faith in them. ATE is a reputable brake company.
