Post up your current set-up mate.

the standard injectors take quite a bit to max out bud so upgrade the fuel pump and get a jam fcd and fpr and youll be fine for 1bar of boost on the standard ct9 turbo, if going for another turbo then you`ll need a piggy back ecu or another with a remap.

Now am runing 0.8bar with fmic. Else is standard.

the standard manifold has arestristion on the 3rd runner, which when run at high boost (ie 1bar) it will cause excessive it on piston number 3 and lead to a new engine.

So you will need to get an aftermark manifold where this restriction is removed or you could grind out the restriction on the runner,but this will make the manifold weaker.

I ran .8bar on standard manifold for over a year without problems.
I reckon its only needed to be uprated after fuel cut has been by-passed. just my 2p tho.

I strongly recommend even a stock boosted car to run a aftermarket manifold, ive seen first hand on stock engines cylinder 3 getting excessively hot, and for the fuel system the stock fuel system bar a uprated fuel pump will flow perfectly up to 1bar boost on a TD04 setup, once going past this i recommend uprating the injectors, after that when running serious power you need to look into dual fuel pumps, larger fuel rails etc.

But thats only when running massive power and even then most people don't bother.

Yepp.. monfish did a nice job there... thx for it.

Aniway, I still wont get it. Japps dont do idiotic stuffs, but that thing in the 3d runner... for what the hack??? can it be some wortex generator or so?

Nah, nothing so flash and fancy as that. It's a recess to allow clearance for the bolts that mount the turbo to the manifold.
