Im sorry, i agree with zebra, the engine will only make more torque in higher gears, so the only reason it wouldnt nose over at 5500 in second is because it would be making less torque before that. The other thing is that a drop off in torque is far less noticeable in lower gears.
I would pick factory hard lines over braided in a stock turbo location every time. Plenty of cars still running the original lines after 20 years, wheras i doubt you could say that for braided ones.
IMO if its a t3/t4, then check what turbo it actually is, sounds chinese, so you would be cheaper/better off buying a stocker and getting the turbo highflowed, exhaust front mount, stock airbox, clutch, nistune 250rwkw and almost undefectable
Youre running a stock turbo, so there is no need to upgrade the pump if the stocker is fine. I would get a different tuner if he said the pump will increase fuel consumption. I would get nistune. Wouldnt be surprised if the car makes less power with the boost etc than standard as the r34 ecu's chuck a hissy fit worse than the r33 ecu's
Does your mate have cams, they make an exhaust louder. TBH you arent much down on power, you are only running 15psi, and teh power does increase with boost. Do you have cam wheels?
My advise would be to do the exact same setup as cubes has, 300rwkw, looks completely stock, plenty enough power for the street. If you want a bit more, fit a bigger exhaust housing and water meth, should be able to see 360rwkw
Trent, the setup where you had the gains, what power was the car making? Can i summise that there are negligable gains up to 330rwkw or so, but once you start puting gtrs's and the like there are gains to be had.
Im thinking the people with the leak problem maybe they didnt tap the thread, just wound an m6 grub screw in, then i could see it leaking. On the neo 25/30 i built, we tapped and locktited the m8 grub screw and then epoxy'd it in
