S2000 motors & trans are regularly available on evilbay for around 5K.

I AX ed my Mr2 T once...in the rain.....didn't like it much.
AXing a turbo motored car would take some getting used to....even one that is a factory set-up. I spent WAAAAY to much time goin' sideways.

I watch pumped STI Subies that run is SCCA Street Mod. They are pretty much point & squirt....pretty damn quick, but they have 4WD, ABS, traction control....yada. HP is gud, but controllable HP is better.

Ayup, the S2000 is way down on torque until it hits the power band (still gets TTOD), but with a light car that wouldn't be as big of a deal, plus the supercharger would make up fer it.

When I AXd the turbo 914 is was fun: Set for turn in, get near apex, speedway through corner after boost hits, try to keep the tail lights pointed more than 90 degrees from the direction you want to go (IMG:style_emoticons/default/wink.gif)
I did back into a few corners but I backed out of em to make up fer it (IMG:style_emoticons/default/wink.gif)

The V8 car was the most fun fer AX. One guy walked up and asked me how I could get such a good time with my clutch slipping so bad out of all the corners.
I tole him it weren't the clutch slipping, it was the back tars (IMG:style_emoticons/default/wink.gif)

I drive an EJ20 every day.

They have no torque down low. Below 1500 they are totally gutless. I think someone here showed that they had ~70HP until you get above 2500 rpm. Above 3000 they really wake up and pull pretty much to redline. This is a completely stock engine.

I hear that you can remove the cats (especially the one before the turbo, whose idea was it to put one there??) and help the low end quite a bit. Higher boost will probably help too, or a resized turbo. I don't think it is hopeless but I think the stock EJ20 may not be so good in an autocross unless it is a very high speed course.

The 2.5 based turbo from the Sti, Legacy GT, etc has a ton of power from significantly lower rpms. That engine in stock form might be a lot better. I think the extra 0.5L of displacement helps a lot.

The STI engine is entirely different then the EJ20T. The internals are beefed up significantly and they run different compression, heads, etc. Ive been in a stock WRX, a modified (with no cats) and an STI and personally they dont hold a candle to a 2.7 914-6, but possibly if one of those engines were in a 914 it could work. Just make sure to either keep the stock turbo (small) or get a smaller one for the Auto x course. I think they make too much boost too late, but then again I hate turbos (IMG:style_emoticons/default/biggrin.gif).

The 2.5 turbo is indeed a wonderful engine. My wife's Forester has one, and it makes that 4000lb station wagon really move from 2000rpm all the way up seamlessly. Zero lag. That engine would be wonderful in a 914.

Paul,

That looks outrageous! I'm looking forward to seeing it done and seeing how it changes your weight distribution.

I really opened myself up for that one, didn't I?

Thanks Chris, but I won't be coming back to your shop this Christmas.
You need to come down here.

"No power below 2,000rpm" - my answer to that is that I don't think that I've EVER seen less than 3,000rpm in an autocross from launch to finish. If you're in an autocross in a 914 and you're pulling at 2,000rpm you're in the wrong gear. Also, to say that the WRX doesn't feel that fast misses the point. We're talking about putting that engine in a car that weights HALF of what a stock WRX weighs. It would be fast. Blisteringly fast.

Ok... FINE. I'LL build one.

it's a 1975 tub still all steel except for the GT flares which are riveted on.
rear tires are 23.5x12.0-15 Hoosier R35 on 14"wide x 15" dia wheels. 5.5" backspace.
front tires are 22.5 x 9.0-15 on 10" wide by 15" dia. wheels with 4" B.S.

weltmeister 22mm front swaybar, 22mm swayaway T-bars, 250lb springs rear, Koni reds all around. Poly bushings with monoball upper front strut mounts. As Paul mentioned it was a V6 (2.8 Chevy) for 6 years and I had it working pretty well. Now with the V8 I'm starting the tuning process over. It's still pretty heavy and this winter I'm doing a lot of cutting.

The car is really too wide and I may try narrower rear wheels next season. 12" wide.

I have more pictures at home. I'll post later.

Keep it going Mike,

Tell me what kind of HP the 2.8 put out. What about a 4.3?

And tell us about your current V8.

You got me thinking....and that ain't good. (IMG:style_emoticons/default/idea.gif)

Yeah, me too. (IMG:style_emoticons/default/happy11.gif) Do I see a 914-8 project in my future? Hmm?

I haven't ever really seen a 2.8 that was any good, but have seen quite a few rockin 4.3's. (IMG:style_emoticons/default/driving.gif)

Snag one of the Lexus V8s. 250hp and 260 ftlbs stock. Ditch the crappy exhaust manifolds and free up the intake and you could easily go over 300 with almost no weight.

The suburu problem could be solved with a decent turbo, good exhaust and good intake plumbing. You could get torque without any trouble. A ball bearing turbo with a divorced wastegate and properly designed header and exhaust system would fix all of the problems.

For autocross I would look at the Scubby motor. Light and cheap. Good after market.
