Just wanting a little help with my current build, if you guys wouldn't mind.

I've got an '04 Z06 with an A & A supercharger kit on it (Vortech V3 Ti), 4" pulley, TFS 220 Heads, BTR Centri Stage 1 camshaft, Kooks 2" longtubes, ORX and Corsa Xtreme. Monster S series triple disc clutch. Chris1313 fuel system. Still in the process of putting it all back together, but this parts list will be the end result.

I imagine the car should make around 600 rwhp from what I understand?

It's a street car. I'm not planning on drag racing this car or putting the car on a track at all, frankly.

My question is at what point should I consider doing the transmission and rear differential? If it's being driven on the street, I would assume that the stress put on the drivetrain outside of the clutch wouldn't be too extreme, right? Do you guys think that the trans/diff should live for a while behind this setup? Or should I just bite the bullet and do them now? Trans/diff are not a cheap investment and the car only has about 9,000 miles on it.

Eventually, I do plan to pull the motor and do a forged short block, so maybe I could wait until I do that to do the trans/diff... but if they can't hold up well to around 600 on the street, then I may as well do it now so I'm not pulling the drivetrain again in short order.

Thanks!

 

Do you plan to do burnouts and drive like a youngster? My vote is drive it and see what breaks first. My money is on the half axles.

 

You're probably more like 550rwhp. 4" pulley and stage 1 cam. That car can last a long time on the street at that power.

 

Sounds good guys, thanks! I'll just do the clutch and keep the stock trans and diff in it for now.

I was only saying 600 because that's what the guys at Speed Inc were telling me with the TFS 220 heads and cam along with the Vortech. Sounds like I'll be fine running it as is on the street either way though - thanks for the help.
