Hi,
I'm doing a turbo upgrade on my 91 SR20det and just wondering what products are necessary and requesting a little information. My car currently has a boost controller, exhaust, hks pod filter and pivot air fuel controller. These are the products I have bought so far.

- T3/T4 turbo (Specs: .50 a/r compressor, .63 a/r turbine, .57 trim)
- aftermarket exhaust manifold
- 700 x 300 x 75 intercooler and piping
- Cat converter
- turbo exhaust piping (yet to be made)
- 3" cat converter

Q1. Do I require other parts e.g. fuel pump and/or injectors?
Q2. If not what boost should I be running with this setup with stock intrnals?
Q3. If yes what size injectors and fuel pump at what boost?
Q4. Will my car require tuning or is it possible for me to do it myself?
Q5. Do you know of similar posts with a step by step run through of this sort of turbo upgrade? (I've been having trouble finding a detailed one thus far)

Thankyou for your help!!!!:bowdown:

You should have already purchased a high pressure fuel pump, at least Ive heard...and I am 95% sure your car would need to be tuned after installing a bigger turbo with a different ratio and such etc...but Im no expert with that stuff so Ill let the other guys talk tech with that :-)

I know if you need a fuel pump, theres the Walbro 255lph ones for sale in the for sale section though

Everything you do will depend on what your goal is.

This should help you pick out injetor sizes. Of course you don't want your injectors at 100% duty cycle. Do some math and find the injectors to be at 80% duty cycle.
