Looks like a lot of work and looks like you have got a good result, nice one.

Cheers, yeh I made it up out of sheet alloy. it was a bit of a *beep* to get to fit but it gives you so much more room on that side of the engine.

Yeh I agree it should be tucked away from the factory, the standard overflow it ugly!

this thing been on the dyno or what yet? twins look so sweet under there, good job.

oh you need a throttle body relocation or plenum bad, the intake temps are gona like that piping going right next to the dump pipe....

after doin this you know the exhaust side of a falcon on first name basis, what you reckon about putting a smaller turbo gt30 torwards the front and a big sucker like gt45 towrads the back?

im so keen to do this I have a block sitting on a stand begging for some twin action.....

you could do a dual stage twin setup, it would work but im not sure if the power output will be as good as you would hope for. you would have to build your exhaust as a simple log manifold to keep your space at a maximum. that's the only thing I wish I would have done instead of making a fancy directed flow manifold just do a simple log. their ment to be the best for the thermal force on the turbine.

if you want power from idle, youd be better off using a vortec super charger to make boost from down low then use a massive turbo say gt45 or bigger to take over the top end and keep the vortec spooling hard as well

Project update,

I havnt been on to add updates for a while, but the latest on the TT project is, took it down to Autotech engineering to get dyno tuned. Cylinder number 5 was found to have low compression, so the engine has since been pulled out and everything has been BEEFED up with stronger internals.

The compression failure was due to a burnt out exhaust valve.

Forged pistons and forged conrods have been installed, 24 new valves and the seats all re-cut, nizpro valve springs 80lb injectors and 550hp walbro fuel pump.

a custom intake plenum has been fabricated to reduce pipe lengths, and a new intercooler.

then engine is fully reassembled waiting for some spare time so it can be put back into the car!

ill post sum fotos of the progression so far.

The new plan is to increase boost from 8psi to 18psi!

get some real power outta this donk!
