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

      Dose is unaware just how much fun 145-150kw would be in a 2.5L NC MX5. It would be one of the most fun things to drive to ever grace SAU.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By dbm7 · Posted

      Same thought crossed my mind ~ depends on how one connotes 'stalling'...ie; gets a rough/stumbling idle as it get warm until it stalls... or... idles ok and simply falls-over when it gets to temp... ...you can test the whole circuit with a couple of resistors ...unplug coolant temp sensor, bridge terminals with a 2K7 resistor (ECU will do cold start), or with engine warm bridge with a 330R resistor (ECU will consider engine to be at normal operating temp)...it's a quick way to check wiring integrity/ECU response when you don't have a multimeter handy ...

      They also make them with the motor mounted on the side

      Just be warned that that turbo will not be a direct re-fit to the car. The exhaust housing is, of course, in the same place. It has to be - it's bolted to the exhaust manifold. So the dump will fit up. But the centre housing is not as long, so the comp housing will move backwards. This will affect both the turbo inlet and the outlet. There is fab work that needs to be done. Yes. it has one, it should have one. Paper gasket.

      Exhaust silencers/varex exhausts

      By PotatoCake · Posted

      I only recently purchased the vehicle, it came with the flex setup but the current tune is e85 only, which is why im wanting to get the tune redone to enable a mixture.  First i need to get the exhaust redone tho. I was thinking of getting a varex muffler but it sems they dont fit well in the 33 (hang low because of the valve mechanism which sticks out on top) and generally dont sound good. So that leaves me with redoing the entire exhaust (more resonators and mufflers) so its not a menace when i come and go from home, and then have the aes dump valve somewhere along the line to really open it up. I was thinking of having it before the cat but after seeing how insanely loud it will be (on a vl turbo) im thinking of putting it more towards the rear of the car, after one of the resonators.
