Nope. But if you're willing to pay for it, I'd be happy to.

My calculations are based on desktop dyno, reverse calculations on the 1/4 based on gear ratio, and known BSFC limitations of stock injectors at 4bar fuel pressure. All 3 calcualations put me between 310 and 320 CHP.

And if you compare that to the S2 cars that run quicker, then do the calculations with the shift points based on horsepower curves, it all jibes almost perfectly.

The S1 will beat the S2 off the line, then lose it'* *** on the final half of the 1/4. Horsepower being equal between the two.

I'm more interested in what the power curve looks like when you open these engines up. Peak numbers only show so much. I haven't had much luck finding dyno runs on the s1s on this forum, do you know of anyone who'* done one and posted the charts?

Thanks for all the help btw, pictures should be coming in tonight. Things aren't looking good with this engine. The Odometer said 70k, we'll see what the internals look like sometime tonight.

Numbers will be off, but the curves should be the same.



This is from an L27....the less powerful sister. A general estimate of 20% over those numbers should be good enough to bring them to L67 specs. But those curves *should* be in the ballpark.

Those curves are way off an L67. The 67 torque curve peaks sooner and is much flatter. There'* no comparison to an L27.

Belay my last transmission.

it may not be an L67, but it'* always good to see dyno charts! thanks sandrock

JC, that curve will be NOTHING like yours. No closer than a VW beetle would be.

Sounds like a good project, but I myself might question the motor choice as well. For shear power output i'd look at an L32, or LS4, LS4 is the lightest of these motors discussed so far, and if anything has more parts that'll work for it easy enough than a 3800.

Heck, get the new 6 speed FWD Manual Tranny, and an LS4..

EH, the L27 would be much closer than most VW engines...

Any talk about changing to a different series or different engine is a moot point. This engine has presented itself to me, and I will be building this engine. If the m62 turns out to be a huge sticking point to me not making it into the 12'*, I'll turbocharge the engine instead. This thread is about a 94 */C 3800 and its potential, lets try to stay on track here guys.

In the meantime, I did almost a complete disassembly tonight on the engine, and found out that it will need rebuilt. The whole engine will be getting cleaned and repainted, including all brackets and cleaned/painted nuts/bolts. The cylinders may need to be bored out, it has some surface rust that has built up and I'm not sure that a simple honing job will fix it.

Just imagine this as a project s1 */c 3800 guys, this is going to be an extensive rebuild and I am open to suggestions (for the s1 */c 3800 that is).

What does the Fiero weigh? What does the stock drivetrain weigh?

A cam will have to be custom to your specs. When I do a cam, I'll be modifying duration only, and keeping my 1.8 full rollers. I'll be copying existing cams somewhat, but taking into account the lower rpm shifts of the S1.
