Is there any difference between the Auto and Manual 2G turbo ECU's? Are they interchangable? And is there a speed limiter on the Auto 2nd Gen GSX?Thanks,Andre. :dsm:

I have a 99gsx and mine failed with 35k miles, I instaled a underdrive pulley from extreme turbo, It's way cheaper than a damper pulley, but if you have the cash go for the underdrive damper. I believe Buschur Racing sells one.

If you drive hard all the time or your engine is producing more power than stock I'd recomend 20-50, it has a better film strength so it can handle more pressure without letting the metal parts touch (that's when your engine wears).

the pipe that says hose and conects to the 90 degree elbow is the lower i/c pipe that goes to your intercooler,You can port the outlet with a dremel, just buy a carbide bit for it, not the stone, it'll clog up in no time.

you can probably use your rubber hose, but a 90 degree elbow will make it easier, I have a greddy lower i/c pipe (cut about 4inch shorter) so I'm not really sure about that.You don't need to port the outlet larger, but it'll help a lot if you do, it's really easy.

Id say 10 to 20, If you bypass the cat (remove it and install a racepipe) you'll probably get close to the same results without all the noise...

Turbos do create a lot of backpressure, usually on small street turbo you have more backpressure than boost, on large racing turbos (usually with nitrous) you get something called crossover, that means that the pressure on the intake manifold is higher than the pressure on the exhaust manifold...

you don't need the full kit, you'll need a J pipe, SS oil feed line, coolant hoses, 7cm gasket (if you're porting your manifold and turbine housing to 7, otherwise just use the 6cm), and hose clamps, you'll have to switch the coolant lines position, you can bend them if you need and use the...

That's true, your car will accelerate faster on a lower gear with the same horsepower, so it's better shift after your power curve begins to drop, and that will put you closer to your power peak on the next gear. I usually shift at 7750.;)
