hi all found this site and couldnt resist

bought a import r33 gtst

i got it really cheap as the there was a shit load of parts missing from interior but finnally got that sorted

i got plenty of questions for nsw sydney people on like places to go to find mo info on wat parts are in my engine and things so that help would be appreciated.

attached photos of how she is now

from my research i know it has a bigger turbo than standard

has a front mount intercooler

i installed volt guage and didgital boost guage and greddy turbo timer.

firrst question may sound dumb but i feel its under powered and spludders around 4500rpm and if i go past 1/4 throttle

i am led to my investigation its due to intercooler and bigger turbo intsalled by previous owner and if it this do i need a aftermarkt ecu or just a nistune ecu

thanks for reading if u actually do hahha

you coulkd be right. however id be checking your coilpacks. 4.5k is where they notoriously break down. if your modding go a full set of splitfires or brand new nissan ones. also if it does have a bigger turbo but standard ecu it would drive like shit... and i mean shiiiiiiiiiiiiit.

First off, congrats.

Second, this is the place for all information.

Third, did you get a comp test done? Change the spark plugs and gap them to 0.8mm. See if that makes any diffence. Then take your car to a tuner and get the nistune that you suggested. It will do fine.

Is your car running more than 10psi? Or is it at 7psi?

Best thing would be to just throw it on a dyno and see what is going on with it.

Thanks for the replies yeah I know about the notorious flat spot but its wierd cause even if I go slow it does and worse if I punch it past

well on my boost guage it goes to 10 plus psi and shits itself real bad at 11psi

I have done plugs and gapped them coil packs are fine I think

welcome.

looks like a nice car.

hope you get the issue sorted quickly.

thanks luke yeah me too from all the help on the site and big help from plattsy im on the hunt for a greddy ecu found a few on ebay for around 400 bucks so yeah and im off to garage 88 as i here there pretty good to see if they tell me whats done to my motor and go from there

Head over to Adaptronic too. Have a look at the Select range of ECUs.

Direct plug and play, no need to cut or mod anything to fit the ECU.

awesome thanks they look the good but dont have 1500 bucks right now just for a computer kinda need to do the cheaper thing until my other car sells hahah

    • 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.
