hi all, I am just building a 500kw ATW motor and have a new exhaust manifold , when we installed it on the bench the bloody thing looks so high the turbo housing is above the oil filler cap (4.0L Barra motor)

any ideas. I hear that the GCG manifold (which I have)was discountinued due to uncontrollable boost because the runners were an irregular length and caused issues.?

As the others have said - What Manifold? What Turbo? Who's building it? What interanls are you using to support the power (and what gearbox)?

Pics would help too!

Hi Guys sorry I took so long to reply been away. The internals are Je Forged and I beam rods, Exhaust manifold is GCG with 60mm external gate along with To4Z turbo. Valve springs upgraded. Standard box but 3000+ Clamping pressure single plate clutch with 10 puck plate...

The fuel system surge tank is process west with 044 pump and will be upgraded to have 2 x 044 pumps. with 75lb injectors.

Look at the height of the sucker in the photo, note it is not flush with the flange but bloody high.!!!

Alos any recommendations for tuner.?? MRC Performance tuned the car to 400.5kw at the wheels prior but it leaned out and cracked piston 4 !!! 15k later see attached photo.!

I have spoken to C& V also Autotech and BTA. I think this setup will make 500+ on race fuel.

I think you'll find it will clear, doesn't really look to much higher than where the standard crossover sits.

Oh, and while it out on the bench there, you should look at getting a better harmonic balancer for it, the stock one wasn't designed to work at high rpm and power levels

that is so sick but a to4z.......my mate has one on his aristo and it is so laggy comes on boost at like 4500rpm how much was the turbo and manifold

That is on a aristo mate , a TO4Z on our engines are not laggy, you would be surprised.
