Your car will lose signiicant power if the PFC is tuned for those modifications.

Also running the bigger turbo with stock management is a dangerous proposition unless you baby the car everywhere (dont go WOT or take the revves above about 3.5k) as you risk detonation and engine failure. If you put the stock turbo back on the car would run fine (if a little rich).

Why do you want to remove the PFC?

Thanks heaps guys for the quick repleys and help...

Not sure if im 100% gonna remove the Power fc but my brothers mate offered me $1200 for the computer and hand held controller but i'll probably just leave it the way it is cos i do love my car and dont have the money for any engine rebuild lol

Keep in mind if you can sell the PFC for 1200 and get a stock ecu thrown in you can get toshi (search the traders forum for 'toshi') to remap you standard ECU for around $400 which is a very good option. It will be fine for the mods you have (and as its very hard to detect you wont get defected for it) the only downside is the PFC will be better if you want to do many more power mods in the future (bigger turbo, AFM, injectors, etc).

likely the car will run like a bag of shit with the ATMO BOV.

260rwhp is only 190rwkw, which for a turbo like that is a pretty poor result.

I'd expect closer to 300rwhp at least, and 350rwhp with injectors/AFM

So you wouldnt loose much power right power, would be a bit rougher to drive however as tune could have cleaned it up a bit

I was told that was about the right amount off power for the car as the injectors and fuel setup a still stock...

Also the t4 turbo i have isnt much bigger then the stock turbo, I'm not sure myself im only going on what the previous owner told me.

Its not about right :)

You can take factory injectors to around 220-230rwkw. Every car is different. I made 220rwkw on stock 25 injectors years ago with a T04e, int gated rear.

If its not visibly much bigger than the factory one, then it probably isnt a T04.

Generally a T04 will come with the .7A/R Garrett Comp cover

      Rb25det s1 igniter pin out

      By GTSBoy · Posted

      It's definitely not firing order. But I think it should also be made clear that the output that gets fired is the one that corresponds to the input that was switched at the ECU. So you could scramble them up totally so that the numbers meant nothing, and so long as you had the inputs and outputs matched up, you'd be fine. The reason I make that point is that blanket statements about what it is supposed to be don't always hold out in a world where there's been 30 years for the wiring to have been stuffed with.

      Rb25det s1 igniter pin out

      Hello, im asking about this guy - coil igniter on rb25det series 1 r33 s1 engine. I need to know if pins on coil side indicate coils itself from 1-6 or it’s firing order so pin nr1 goes to 1st fired spark plug:(1pin-1firing spark, 2pin-5order firing spark, 3-3, 4-6, 5-2, 6-4…)   photo: https://files.fm/f/k9pdug38uq

      Powder coat on mating surface

      By GTSBoy · Posted

      Remove it. Certainly from the hub face. I'm not in love with leaving it on the wheel assembly surface either - but if it is common to do so, then....maybe fair enough. It's not difficult. Just time consuming. For the hub face you just need a large enough block and suitable grades of abrasive paper to get it off flat. The same would be true of the assembly face. Just more time consuming, probably needing a lot more care. It's defo going to be easier just to assemble the wheels as is, seal them up, and check them periodically to see if there's any movement or loosening of the fasteners, than it will be to remove it though.

      Powder coat on mating surface

      By dyl33 · Posted

      Hello, I got my wheels powder coated and they've powder coated bloody everything the mating surface and hub (even told them not to lol) anyway should I leave it or remove it. (Would be very hard) I've searched a lot and lots of powder coaters don't mask the mating surface but do mask the hub surface. How bad it powder coat on the mating surface or hub? My question is what should I do?

      R34 Gt Auto Tuning

      Yeah, R34 with RB25DE likely has a 4AX01 box in it, which is a medium duty auto ~ with the RB25DET mill, it would've been fitted with 4AX00 (4AX13) heavy duty build (same case, different internals). An RB25DET will lunch on a medium duty 4R01 auto in pretty short order ...to give you some visual idea of differences between the 'medium' and 'heavy duty' boxes, you only have to look at the 2/4 band for comparison...it's chalk and cheese...(plus bigger high clutch, extra pinion in the planetary sets, higher oil pump output, different bearings, higher TC stall speed )... You can control them with just about any aftermarket TCU for electric-over 4-speed with TC lockup clutch (ie; the GM 4L60E and others)...I have a custom standalone TCU that includes MAP sensor (for turbo applications) along with TPS, RPM, and line pressure monitoring...in other words, I don't use any ECU signals...no real need to.
