first turbo build questions

[TGP37]

i do have a set of injectors but i belive they are not the proper flow rate as they are 36lb out of a 3800s/c. im looking into getting a set from racetronix do i need high or low impedance? or is there a compatible set i can get out of another vehicle?

And a larger diameter fuel supply line. IIRC, 3/8" ID was good up to 500 hp.

I use those 36# injectors. They barely nip 80% duty cycle at the peak of 10-12 psi. I agree with Z26-T, 42# minimal for anything above 12psi of boost. That 3400 is gonna scream with that much power. Just 8psi on these motors produces a hell of an engine.

i was all set on garrett GT35R but i have been talking to a few shops and i got into a discussion on one of the bmw forums and they are giving rave reviews on turbonetics 62-1. so now the question is garrett or turbonetics?

I did the same review when I was looking for a turbo and found that the GT35R was the way to go. I am currently using the GT35R for my build and I did a lot of research on both company's and what I found was the Garrett was by far the better choice. Turbonetics new stuff isn't what it used to be and it's more flash then function. Garrett's are proven to work time and time again.

That Turbonetics 62-1 has been around for at least a decade if not two. It's at least 3 generations old right now. The GT35R or Borg Warner S300SX FWM would be good matches. The Precision 6266 would also be a good match, but probably a bit slower spooling. The nice thing about Precision is that you can get a lot of their turbos with a T04E cover (meaning 3" inlet and 2" outlet). That smaller cover makes it a LOT easier to fit a turbo and intake pipe in our engine bays.

lol 62-1.. i remember thoes.... and the old 60-1 Hifi.. thoes were the shiznit when we got our T04E's. i would run the Garrett or the Borg as well. altho my Trubonetics turbo has been a real trooper... I agree with tim.
