thx for that guys, y do i need to drop the boost?? and also wat do u mean by slot the oil drain bolt?

thx again

Those turbos flow more alot more air at 15psi than stock ones. More air but, only the factory fuel and ignition maps that are suited for the smaller turbos. The factory ecu does run fairly rich usually so you have a little head room for power but, those turbos have a fair whack more power potential than you have margin for error. The main issue may not be right up top either but, rather the peak torque point which on those more efficient turbos will possibly be higher than factory at the same point the factory turbos make peak torque.

Bottom line is you don't want to go guessing that 15psi will be good clean fun. Get the boost right down as low as you can and then throw it on a dyno and see what you can take it to boost wise without getting yourself a Power FC or S-AFC ,at least something. You might be able to run 15psi but, without taking it there under dyno or O2 wideband observation you may find a new bill sitting in your engine bay.

    • Ah right. Maybe my rb just loves chewing through batteries lol.
    • On the R34 can't you just unplug the IACV? This is the way I've always done it on the R33. Disconnect IACV, get it idling around 650rpm, and then do a power reset on the ECU to get it to relearn idle (factory ECU).   The big reason no one has touched on as to why you'd want to get the base idle right, is that it means the computer needs to make smaller adjustments to get a good idle at 700-750rpm.   Also, cleaning the IACV won't normally make the car suddenly idle lower or higher. The main issue with the IACV gumming up is that the valve sticks. This means the inputs the ECU gives, aren't translating to changes in air flow. This can cause idle choppy ness as the ECU is now needing to give a lot of input to get movement, but then it moves too far, and then has to do the same in reverse, and it can mean the ECU can't catch stalls quickly either.
    • 12.8 for a great condition, fully charged battery. If the battery will only ever properly charge to about 12.2V, the battery is well worn, and will be dead soon. When I say properly charge, I mean disconnect it from the car, charge it to its max, and then put your multimeter on it, and see what it reads about an hour later. Dieing batteries will hold a higher "surface charge", but the minutest load, even from just a multimeter (which in the scheme of things is considered totally irrelevant, especially at this level) will be enough over an hour to make the surface charge disappear.   I spend wayyy too much time analysing battery voltages for customers when they whinge that our equipment (telematics device) is causing their battery to drain all the time. Nearly every case I can call it within about 2 months of when the battery will be completely dead. Our bigger customers don't even debate it with me any more ha ha ha. A battery at 12.4 to 12.6 I'd still be happy enough with. However, there's a lot of things that can cause a parasitic draw in a car, first of which is alarms and immobilisers. To start checking, put your multimeter into amps, (and then connect it properly) and measure your power draw with everything off. Typical car battery is about 40aH. Realistically, you'll get about half this before the car won't start. So a 100mA power drain will see you pretty much near unstartable in 8 days.
    • Car should sit at 12.2 or more, maybe 12.6 or 12.7 when fully charged and happy. If there is a decent enough parasitic load then it will certainly go lower than 12.2 with time. You can't beat physics.
    • Ok guess I can rule out the battery, probably even the starter and alternator (maybe) as well. I'm gonna clean those leads and see what happens if it's still shit I might take it to an auto electrician. Unless the immobiliser is that f**king heavy, but it shouldn't be.  If I start the car every day, starts up perfectly never an issue. Isn't 12v low, shouldn't it be around 12.5v?
