Honda S2000 swap

[nando]

195/60 is pretty small. only early cars came stock with that size - I see an airbag in your pic, a 195-65 would be stock for that year.

but, still pretty small for a 200+hp E30. perhaps consider 15" wheels and a 225/50R15 instead. would fix your speedo error and lower the highway RPMs a bit..

btw, really cool swap! now go do one in a 2002. :p

Lsd 4.10

Decay-the other thing to consider is the rear tire diameter. I'm running the 195/60-14 tires and I know the Few stock tire sizes that came on a S2k are larger circumference. My speedo runs about 6% high. I can correct most of that with a larger wheel tire. This will he my next upgrade then I will reevaluate getting a taller rear end. The other thing that took me awhile to get use to is that the F20c revs so high, so at 60mph it tachs at around 3600-3800. In a car that Redlines at 6500 that is quite high, but with a motor that tachs at 9k it really isn't. So I guess when most engines are running out of breath, the F20c is just waking up. I love the Dr Jekyll Mr Hide personality if this motor. I daily drive this car and mostly highway, occasional track day and auto cross too. It's been a perfect all around car, now if I could just tow a boat with it and seat 7! Ha!

I am also running the stock 318is rear end, 410 LSD. I would like to put a taller rear end, maybe 3.73 someday.

i'm surprised to read that- 4.10 is what an S2K comes with out of the box, and having driven both ap1 and ap2 it felt a little tall to me.

in an e30 i would want the numerically highest ring/pinion i could get, to keep the first 5 gears getting me to the same mph as the original engine/tranny/diff combo did, and yay now i've got an overdrive 6th.

that's me, though, carry on and have fun w/ the car, looking forward to seeing what else you do.

Decay-I don't have the weight of a M42. That motor was quite a bit heavier than the s2k motor, just handling them out of the car. I would guess the honda trans is much lighter too. In the earlier post I compared the weight of the s2k motor and the S14. Which I found the F20 to be about 25lbs lighter than the S14. I am also running the stock 318is rear end, 410 LSD. I would like to put a taller rear end, maybe 3.73 someday.

Joncrz-I am using the stock steering rack. I did recess it into the crossmember a bit to help with clearance. I have yet to sort out the AC. I've gone another summer with out it. I would like to get it going by next summer. I don't expect any surprises here though. I plan to use the honda compressor and Bmw everywhere else. Thanks for your interest guys!

[joncrz]

So being a daily... what steering rack are you running? AC? anything you had to sacrifice that you rather not have?

thanks! seriously considering this project...

nick526, no it doesn't have to be from the same manufacture. There are plenty of other cars in CA, like the old Toyota 4x4 with Chevy engines and CARB legal ;)

Key is to use ALL the components from the donor, down to the cat.

the s2k cluster is so rad

[nick526]

How'd you pass smog with an engine from a different manufacturer? I thought it was pretty set in stone that engine swaps have to be same manufacturer, same model year or newer to get the referee to sign off?

[E30.WLA]

What will something like this cost me? Would i be able to use my my e30 lsd differential?

I need to get a complete swap since i possibly have vent valves on my engine.

i am unclear on how it was "a lot lighter than the m42 you pulled out"- numbers i have say you gained ~50 pounds (easily correctable).

what final drive are you using?

[Dozyproductions]

Great swap mate! Any other words on how it does on the butt dyno when putting it through the gears?

Catuned, I just ck'd out some of your projects, very impressive! You are doing amazing work. I'd love to stop by next time I'm in Sac. Thanks for the kind words!

Stop by anytime..

[I<3BMW]

I really want to do this swap. I think it would be awesome. looks great!

Dam were slacking. Just never no time. Good work man. Were working on a mass platform mount kit, etc.
