What timing were the cams set at for the turbo engine? I'm just learning turbo cams an am surprised at their short duration and minimal/non-existant overlap. To you aggressively use the VVT?
Quaife has a regular (QBE60) and HD (QBE69) gearbox. The regular is 375hp, the HD 750hp and has the pump.
More FAB NSFW porn. Downpipe is tacked together and bolts up to the cat back. Not pictured is the lower section that uses a slip joint to connect. MAN this was a ton of work. I'd guess I have 40+ hrs in fabbing this and making bends out of other bends etc etc.
Very tidy, down to the compact Turbosmart wastegate...how much power are you expecting?
I don't know. I think the turbo CAN make about 550whp from what I've seen from other cars using this turbo. Not sure I'll be there. But hope I'm close.

Aren't those around 20psi of boost? Do you think the engine will be limited by detonation/knock, component strength, or engine speed?
I would try to improve the wastegate dump tube so that it has a lesser aggressive angle into the downpipe. It can have a detrimental impact on boost control and stable power at high RPMs

I tried as much as I could. It's at a 45 degree angle now.
yea, Then you break axles, and diffs and transmission and then the chassis starts to break things..... 400 will be nice and only break a few things.
400hp you can do with your current engine NA, with different cam, maybe different heads, and letting it rev.
Luke said the engine was 600hp on pump gas, which could be managed without too much fanfare. At worst, there are nice sequential gearboxes that can handle it. If you want to do some work, a BMW M3 DCT could be adapted; Garage Whifbiz did that for the Supra using a Syvecs S6+(they are a dealer). A modern ECU will let you run traction control to keep everything under control, even incorporating a yaw sensor, g-sensor, steering angle, and throttle position. With DBW, you should be able to change the throttle sensitivity curve to also make it more drivable. Throttle maps and tire wear - OptimumG
The extra power also lets you get more aggressive with downforce.
