yeah that's weird, because standard they are 7PSI, but as soon as you remove the exhaust restriction the boost bumps up alittle bit, usually stock to around 8-9psi.

Can I ask why you're only boosting 7PSI? I'd be up around the 10-12PSI mark myself with your mods.

ummm stock boost levels are all the same... they dont vary unless the boost has been uped from factory, its not like nissan said... yeah k this one can have 7psi and that one can have 8... lol.

and yeah 12psi is the max the stock turbo can handle before it goes boom i was told, even with an fmic and such they recommend not taking the factory turbo past 12psi.

JaR - When will you start to modify your car? Are you still running the factory boost solenoid? You are aware of how to remove the 2 stage boost from factory? That mod was a goodie... :)

as soon as i get it back ( its gettin re-sprayed at the moment ). umm nah lol, but wasnt there a tutorial on here about how to do that??? had pics and all was really detailed from memory...

and I am sure they also told you that 12psi or more, and the ecu goes onto the rich and retard maps? Dropping off about 30rwkw - 40rwkw, making your car surge like a bitch.

10psi is the best performing, until you get a better ecu.

So 10 psi,Turbo back exhaust, filter, fmic, power fc. would anything else be required if someone does these mods?? Like fuel pump,injectors etc?? Im wanting to do the above mods but want to make sure I do it the right way first time round with all the required equipment to make the car run safe but with alot more power.

My series 2 has similar mods to urs. Turbo back exhaust, FMIC, power FC, pod (did my own piping to get some more cold air in near the pod bcoz of the crap boxing it in) and bov. It handles 11-12PSI no sweat. no spikes etc. I havent intalled a boost controller which i been meaning to do. Just make sure u get your chip mapped spot on and you'll be sweet.

I heard stories about maybe upgrading the fuel rails or pump to be able to feed it high up in the revs. I gave it a go and found it didnt make that much of a difference. I was prob running rich, and didnt really tune it but it went fine without. Spose u dont want to be pumping to much juice in it these days anyway. Petrol prices are doing my a$$ in.

      Lets play a game - What is causing my oil consumption?

      Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.

      Are RBs worth building reliability wise

      By Hendasto · Posted

      At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!

      Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.

      https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
