That's nuts but 3500 motor? Why not make some real power with a LSx?


And did C4ZR1's really have inverted coilovers like that?

I dont know what year that car is but 93-94 v6 cars came with a 3.4. The 3.8 came in 95. I "think" the 3.5 is 60* V6 like the 2.8, 3.1, 3.4, etc... The only reason I can think of is that is what the car had in it from the start?

Maybe he didn't wanna do the 3.9, pretty sure that's the same architecture

Neat build for sure

It does seem like a bit of a mish-mosh of desires though. What exactly is it intended to do? Big thing is manual and turbo... and of course other things too.

Yea the 2.8 tp 3.9 V6 is basically the same block through all the years. Just seems like a crappy motor to put with that bad ass chassis like Jesus said

Finaally read through the whole thread. What a great build. And he's doing it all by trial and error. Makes me want to get out and build something

3.9L had excellent flowing heads. Perfect for Boost. Excellent torque at idle and the power band was very flat to red line. Basically you were never in the wrong gear when I owned my 06' G6 GTP.

Still, it was only 240hp, GM cammed it a little soft in my opinion, they should have ran that thing to 7k vs the 6050 or whatever barely 6000rpm redline it was.

Maybe using a V6 will allow him to stay in a slower class since it looks like its going to be a track car. Otherwise I don't really see any advantage of using that over an aluminum block LS motor.

Here's his reasoning for the V6:

I wanted a powerplant that would sit low and as rearward to the center of the car as possible. The v6 that i'm using accomplishes this feat quite well.

The engine sits further back and lower than a LS would. That was the only real decision maker. In fact, Its so close to the center of the car that its technically a mid-ship.
