CTR Swap Into GSR?
I currently have a B20/VTEC '94 LS, and just picked up a '95 GSR shell. My original plan was to part out the LS and swap the B20 into the GSR. I'm now thinking about trading my complete LS for a buddy's complete CTR swap [w/LSD trans and axles], then dropping it into the GSR.
It's probably never been done, at least I can't find any info on the subject. I know I'm going to hear the "B16s don't have enough torque to push a Teg" argument, and I agree, to a point. Aside from the torque output, the CTR and ITR are pretty close in performance.
I don't drag-race, so peak power isn't a big deal. I'm a canyon-carver, so a solid powerband and high revs are more my bag of treats.
I could go a few different ways with the engine build, as well:
-All-motor build, using the CTR block
-All-motor build, using another B20 block
-Jackson Racing S/C on the CTR longblock [version-1 8.5psi kit pulled off my buddy's ITR; was going to be on my B20/VTEC]
Any tips or suggestions? Simple-minded generalizations are welcome as well.

if i'm not mistaken the ctr, gsr, & itr have the same block. the difference would be the internals. i have a b16b block that i'm trying to rebuild & i also drive an integra. as far as the argument in not enough torque, well honda motors don't have torque anyways. try it out, i'd like to see some results.
if ur a canyon carver like i am also :]
id do a small mild build on that CTR swap and just upgrade my suspension more...
we all know that in a canyon run its all about fun and having a GREAT suspension setup. no matter how slow ur motor is, you can still take the turns fast as expletive with a great suspension/tire combo.

WTF? Wrong thread, buddy.
On a slightly-related note, I pick up the GSR shell and CTR swap on Saturday, and it'll be game on. I'll post pics.

Most likely road of travel is to run it as a stock CTR for the time being, and over the course of summer/fall timeframe, I'll build a strong 2-liter bottom-end to swap in.
I'm possibly going the individual-throttle route, so right now I'm torn between all-motor and supercharging.

Thanks for posting up, redline9k831. I was wondering about the deck height issue, but hadn't yet searched. Just one more benefit of the complete CTR swap - the short-geared LSD trans.

So there's been a bit of a bottleneck in my swap plans. Seems the source I had for the CTR swap was pretty shaky about selling just the motor and trans, and decided to sell his car as a whole for more than I could possibly get for it. So for a bit there I was unsure of what to do.
Found another CTR swap, from a buddy of mine I went to high school with. He's going a different route with his EF hatch, and wants to help me out as well. He's got the complete CTR swap, LSD trans and all, for $3k. I'll just need to modify an OBD1 harness to fit the engine - I'll lengthen, shorten, tuck and clip everything at once, to clean up the engine bay as well. Should be good. I'll keep you guys updated.

ur my hero , my buddy has a ctr that stock motor moves!!, i love that motor , , i told him i would trade in a heart beat, just swap the crank ! gsr or itr should do it . his friend has a 4 door ek running crazy times at the track . good luck let me know how it goes .

um before u go postin info thats not correct all over the place, u do know that he's talkin about the b16b right? all the info you gave was on the normal b16, not b16b
The b16b (ctr) has the same block as the gsr/itr so all have the same deck height , but ctr has a shorter stroke (diff crank) and different pistons.

Thanks for the info! I had heard it mentioned in passing that the CTR's B16B was different than standard B16As, but this confirms it. Thanks again.

which thread?
i know last year when i use to be a big touge'r? anyways, i use to be into it real big before i got an interest into circuit. i posted a thread in the stories section, it was pretty detailed about how my stock LS with just suspension mods beat a V6 mustang GT on turnbull canyon in whittier, CA. that was a great race, the best one ive had ever... i even had 2 passengers.
good times

I'll be looking for ITBs and possibly S2Pro2 cams, maybe I'll go all-out and get some Toda VTEC-Killers.
