I've encountered this same problem, with so much heat under our fuel tank my fuel line kinked. The first year or so the lines are ok, but they weaken due to age and heat and the constant bending. The fuel was restricted (inlet side of external pump)...leaned out motor..melted pistons. CHECK and...

Our Busa's have allot of oil pressure. Make sure you have an oil restrictor right on top of the turbo center section. Plain bearing turbo use a .060 restrcitor like this link. GT series ball bearing turbos have .035 restrictor. 4AN TURBO OIL RESTRICTOR FEED LINE FITTING ADAPTOR T3 - eBay...

jkwool, With a Wide Band O2, do I use the narrow band output from my WB O2 hooked up to the factory O2 sensor wire? This should allow me to get an accurate reading while under boost (3-bar GM sensor ECUEditor boost control)

Hey what happened to the service manual sticky that used to pinned? any where else to get one?

For those that want a alternative secondary controller choice at half the price of a MicroTech(considered Junk in Australia) For the last year on my Gen II, I have been using a controller from 034Motorsports, only $280. Been flawless, simple to use, can't beat for the money. 034 MOTORSPORT

as a Heads up....Keep an eye on those Right side fans motors, mine does nothing, left side working ok. Removed fan and put 12v directly to it...nothing doesn't even try to move. ???

Installed per there "new" instructions, bottom threads in case torque to 12lbs... put the block, head and new cometic gaskets on the engine, and the damn studs are 1/2 of an inch to short..the stud only goes half way through the nut?? These studs don't have the machined allen wrench in the...

I found the limit of an Stock 08 Turbo, non intercooled. The head lifted at 11.4 psi. The failure point was in the rear of cylinders 2 and 3, top side of head gasket. Would blow out rad overflow. NO damage to head, valves or pistons. A/F 11.5, VP C16 fuel, no timing retard, 2ndary injector RCC...
