Hi guys.. just registered :rant:. I have just purchased a R34 GT-T (Not my first skyline i had a non turbo r33 95 skyline) My question is in regards to the boost setting for the standard neo turbo just for street use. The mods on the vehicle atm are minor just cat back 3 inch exhaust, bov, and airpod. I need to know what boost is recommended and what boost not to exceed etc. I also want to put a front mount intercooler on and possibly get the turbo highflowed does anyone know of any good reliable shops in the brisbane area that can do these mods. Thx for your time guys.. no doubt ill have heaps more questions as i learn more about the RB25DET.

the compressor wheel is plastic or ceramic (unsure) and will get angry over probably 12psi. Try it at say 11psi and see how it goes. The stock ecu will have boost cut limits etc but it wont prevent ceramic compressor wheel failure due to heat from the excess boost. You should get good response from 12psi, pod filter, exhaust and intercooler easily 200rwkw i'd say

Thx for your help.. The turbo engine is a completely new world for me. Im not even familiar with the boost controller atm. Going from the non turbo 33 to the GT-T is awsome .. such a massive difference in power. Im aiming for a 250 rwkw after the highflow and intercooler. The last thing i want to do is blow something cause ive upd the boost to much. Thx again

Turbowns,

Firstly, congrats on an awesome step up, R34's rock!

Boost, many claim that all it can handle is about 12psi, I have been running 14odd for over a year no probs, however std boost on mine is about 11. Be careful because the turbo is ceramic/nylon. Make sure you get FMIC before playing with boost too much (and turbo back exhaust) or you will seriously risk f%&king your turbo.

Can't comment on hi-flowing turbo as I have heard conflicting stories.

As you mod the R34 more the first thing that will annoy you is boost/fuel cut, a safety measure to prevent overboosting/detonation. Regardless of mods the only way you will get the car above about 200rwkw's is by changing or piggybacking the ECU (ie Emanage/PowerFC etc). I believe to get to 250rwkw you will also need turbo back exhaust, FMIC, ECU mod, fuel pump and injectors if not more.

I have heard good things about 101 motorcafe, particularly for ECU work. Give them a call and they should be able to guide you through the whole process, alternatively on the GC try Autech (Gavin Wood) in labrador.

Cheers

What year/month is your 34?? If it is a late 2001 (Series 2) onwards you may find that the turbo is metal/metal.

There is a detailed thread on this site about the differences between r33-r34. Here it lists a guide on how to find exact details of your car.

Hope this helps.

      S1 rb25/s14 starting problem

      By Duncan · Posted

      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

      By 25zenki · Posted

      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.
