GT42 turbo on a custom setup

[LeoGSVT]

well..im starting the planning for my custom setup this week..the motor is comming out thursday and being re-built so im going all out while its apart..im thinking of doing a GT42 turbo...im having the people who built the TT ford GT fab me up a custom kit...i have a GT35 turbo sitting around right now..but im afraid it wont produce enuff power...what is everbody's opinion on the 42?? how much will it handle? should i steup is up bigger????

35 is pretty much the same as a 76 so you could go bigger. A 42 is f*ing enormous though.

With a 42 you'll be the interstate king!

I think the GT42 he is talking about is the 76 mm . GT35s are good to 650hp if I recall right.

yes correct..the GT35 im talking about is a smaller turbo something like a 60trim..if im correct...they run them on STI's and Evo's and such as an upgrade...im getting a GT35 for free pretty much so im just seeing what my power level with that would be..and if i need to step it up...the bottom end is being built so im shooting for 800ish

I think your bottom end will be a little soft, but it just depends on what you want to do with the car. If you are gonna drag it frequently it will be fine. If you want a devestatingly fast street car, its probably too big, at least for me. I like full spool or very close to it by 3500 RPM at the latest.

a GT35 would be fun. the 4.6 would spool that thing very quickly, it may run out of steam on the tope end depending on the trim.

Turbos can get confusing especially when talking about their A/Rs. Remember that GT turbos can have different impeller sizes ie GT47-80 and GT47-88.
