Agree with the comments on the injectors. If highflowing, make sure that they can get a flow within about 1-2%, with a spray pattern that is equivelent to stock. I would want to see this personally, as I wouldnt trust it otherwise.

If you upgrade the injectors, no need to get a Fuel pressure regulator. Some guys on here have driven the RB20with 230rwkw on stock injectors just with fuel pump and fuel pressure reg. That is the way I would go if you are looking for 230 - I have also driven in a car (RB20) with 230 at the wheels with stock injectors, and no probs.

2530 is a good choice, I think a GT28 probably wont be coming on boost till about 4000 rpm. I havent been in a 2l with GT28, this figure is from what others have told me.

The hp rating that garret give their turbos is at 1 bar only, so if you wind more boost in, you will get more. This probably explains why horsepower in a box say they get 500hp out of a 400hp turbo.

      thanks for the advice on the box... i was thinking the 6 speed was better for cruising on the highway but on closer inspection and comparison the Rb 5 speed box was not too different...  So the choice is going to be the RB25 box... if I can save up and find one at the right price

      Thanks Matt, yes that's what i am aiming for. Just going to apply the right voltage and grounds to the dash connector. Hence my search for these pins... any chance you know if these pins are in the same spot as the ones on the S15 Dash connector? as mentioned above on page 8?

      Yes, unfortunately that's the one. Signal was noisy to begin with; after driving once and looking back at the logs I saw pressure constantly swinging between 0-200psi, or staying at 0 randomly for a few seconds. There's a lot of good sensors that share the same look and feel, so don't presume they're all bad. I bought mine for 20$ off Amazon and I should have read the reviews prior, as it's clear they're junk.  I purchased a lowdollerr motorsports sensor.
