Am thinking of changing the housing on my turbo to.63 was going to change turbo to a T38 but fancy keeping my gear box lol, was also thinking of changing the injectors to siemens 55's. and also thinking of putting a swedish plenum and air injectors on cos i quite like the look of them lol. Was just wondering what sort of power difference this would make if any. And would i have to change the chip ?

my engine is similar spec except t34/63 turbo and live mapped. the car is dax rush 4wd (800kg) and i thought the std box would be ok given the lower weight and i dont do launches etc. now on its third!.

both times its gone when changing up to third. SO... i bought a TT T38 as i was advised this would reduce the torque spike around 4-5k (with more power later).

there you are - you're worried about wrecking the mt75 by getting a T38 and i bought a t38 to save it!

oh - I'm sure you'll need a nw chip as well

So has it been alright since you got the T38 mate ?

righthooker

i have a t34/63, running aprox 340-60, no probs with my box as yet and i dont drive like a fairy either, i think if u change the housing you will need a new map mate
