Well winter is coming up fast and so my project begins. I have an caged 86 n/a and a 90 gxl with a newly rebuilt and streetported motor that are going to make baby. Im trying to get a list together of parts i should start collecting and need some advice. My motor has high compression rotors so im limited on how high i can crank the boost. I also plan on running a megasquirt. So my questions:

I want to be making 300-350 at the wheels and have a fairly quick spooling turbo. What should i be looking at? Ive heard good things of the gt35 i think it was.

What is a safe amount of boost to be running?

What size injectors and fuel pump should i be using to support this setup?

I know almost nothing about the turbo world so any help would be great

 

Are you trying to put a turbo on the 86 N/A or on the 90 N/A? or do you want to put a turbo charged engine into it (them?) or to just turbo the engine you have?

Either way the FAQ should help sort you out.

 

Ya... We'll need to know the compression ratio of the rotors you plan to use. 9.0 rotors run 15psi on 93 octane with no problems. With a streetport and gt35r at 15psi you can be making about 400whp with a mildly ported turbo motor. If you plan on making a NA motor turbo'd I'm not sure about the flow of the 6 ports so I can't really tell you how quickly you can make boost. Also, you'll need to decide what boost levels you'll like to run so you can determine approximate hp then decide how large of injectors you'll need. Most turbo owners run 550cc primaries at 1680cc secondaries which shouldn't be a problem with any standalone system. And those injectors can handle 500whp easily. Also, you'll have to fab some manifolds so you can run a turbo with the NA manifolds if you plan on utilizing the 5/6th ports.

 

I am using the s5 n/a motor..so what ever compression those things are at.

 

I was thinking i could run around an 8-10 psi max. Can anyone out there fine tune my guess. Also would the t04r get me to the hp i want to be at or would the gt35r be a better bet.
