Cool thread, kinda along the lines of what I'm doing - subscribed and will share my results along the way

Hoping for a close to stock response 230-240kw, which will be exactly what I'm after

My setup will be -

HKS 2535 turbo, hoping to run around 18psi (have turbo but not installed yet)

Split dump pipe - installed on stock turbo at the moment, quite a decent length split section

Nistune - installed

Autobahn88 intake pipe - installed

Injector wise, im either going to use a set of R35 GTR injectors, from what I've been able to work out they are 560cc and direct drop in, or a set of larger injectors if I wanted to go E85

I'm guessing the stock AFM will need to be upgraded to a Z32 or R35 GTR unit

Look forward to seeing the OP's results

I had exactly this setup- particularly the turbo. It is a great turbo and I really enjoyed it. I had 17psi at 3250rpm. and it come on smooth and holds boost well. But for the HKS price tag you often have to pay for them id say you would get the same if not better results with a Hypergear turbo. ALso if you kill the HKS you have to pay the Garrett price tag for a new CHRA. If you already have it- enjoy, it is a damned good turbo. If not, spend on a HG highflow id say.

My car has greater than 260 rwkw and has 100 rwkw by 3000rpm. This is on regular 98 octane, and I'm confident I could push the turbo harder to achieve closer to 300 rwkw - but it is really not neede

why would you bother ? 1000cc bosch injectors are cheap, ask scotty

So I've decided to go ahead and put together a setup which offers similar response to a stock T28-turbo RB25, while maximising mid-range power and response. I think this is ideal for a mostly street-d

      So, good news and bad news Bad news first: The intake plenum is lost in the mail apparently, I haven't paid for it yet, and MX5 Mania are still chasing it up, farking 'Merica postal service  Good news: Any retune will be free if and when it turns up,  I'm still keen for them to throw it on The car goes noticeably better, with only the typical initial take off thingie from a choppy cam and manual transmission, but giving it just a little more RPM than before gives it a smooth take off (and hour or so of peak hour traffic sorted that little skill out) Car made around 145kwatw & 225Nm (Intake may get me to 150kw, maybe....馃ぃ) Weirdly, 145kwatw is the same max power that my standard 2015 WRX STI made a few years ago The cam really comes alive from around 3.5k and keeps making power and holds it flatish all the way to 7k, whereas before torque would drop hard around at 4.5k Drive home was sadly in peak hour, although I did get a little clean air here and there to wind out 1st and 2nd a little bit, and whilst the gains aren't anything for the "boosted boys" to be impressed at, the thing is a blast to drive The sound in the vid is poor, as it is in a undercover yard at work, but, outside, in the wild, it sounds awesomeballs to my ears with all the choppyness I consider it money very well spent for the outcome  Cam specs for reference (Basically the biggest you can fit with stock pistons) 20250417_171807.mp4   LOL, I don't think I will ever grow up

      R32 GTS (RB20DE) Injectors Replacement

      Swap the injectors around and see what happens. If the misfire follows the injectors then that's a signal, if it doesn't it's probably not the injectors.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By joshuaho96 路 Posted

      R33 with RB26 seems to go off of learned voltage for idle. Seemed like whatever the baseline voltage was once ECU first gains power will be the idle voltage. With ignition on unplug/replugging the TPS would relearn the idle TPS voltage.

      Have you confirmed the 2 pin coolant temp sensor on the motor is working properly? I've had a very similar issue when I forgot to plug mine back in many years ago.
