I'm looking at buying either of these turbos (can get garrett turbos cheap new)

im also going to be doing top mount manifold, wastegate, front mount and bov at the same time. and will most likely upgrade fuel pump, injectors and ecu in teh future

which of these will be better for my application?

how much rwkw?

when will they come on boost and be at full boost?

Cheers

PS. i know your probly all sick of 'which turbos shoul i buy threads' but couldnt find which of these would be better fr my car :(

oh ok

once im finished im wanting about 230rwkw-ish, give or take a bit. just going to be a street car though

ive only got standard injectors at the moment. the motor is stock apart from apexi poddy, catch can and 3" exhaust

I would personally go GT3071r IW(internal wastegate), and use a stock rb25 manifold. The whole hot side will look fairly stock, and be reliable. You should be able to see about 270rwkw @ 16psi without overstressing things. You will need RB26 injectors, gtr fuel pump, and some engine management.

ok mint. im going to get a top mount manifold 4 some bling factor lol, so guessing ill need new oil and water lines. and 2 change the intercooler piping. wouldi need the spacer with the top mount?

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
