Getting Rb20 Tuned

I'm thinking of finally getting my r32gtst tuned and since my family is heading down to Perth in a month I wanted to book it in for then.

Currently on the car:

FMIC

Rb25 highflow turbo

Mbc

3.5inch catback

Before I tune what other mods should I get I'm chasing roughly 300whp.

Thinking of:

3 inch down and dump pipe.

EBC? What's a good/cheap one?

Injectors? Gtr ones with resistor pack or what else will drop in?

Bosh 040

Do I need a fpr?

Should I just ask the tuner to supply the nistune board or am I supposed to get that my self?

Also will the tuner be able to fit injectors/wire up resistor pack + fit nistune and tune the car in two full days?

Sorry for all the questions :)

3" inch downpipe and elbow will help yes.

Which actuator do you run on your turbo ? The RB20 one give more boost.

I never runned a standard turbo with 3in exhaust, but you should get 1 bar with a complet 3 inch exhaust.

That's what i was getting on my ca18 with the 3 inch turbo back exhaust and the standard actuator. The CA runs 0.7b stock just as the RB20.

The EBC is not needed if the actuator is beefy enough to get you to about 1b.

As for the injectors, the GTR ones needs the resistor and a "hack" job on the harness. Not a good solution IMHO. Not the one i would choose if it was my car.

I don't know about injectors dynamics, but deatschwerk and siemens have injectors that are drop in. You just need spacers on the fuel rail for the siemens ones.

The fuel pump is mandatory if you want to keep your engine happy and alive. The oem pump is quite old now, throwing high fuel pressure and bigger injectors at it will get you in trouble pretty quickly.

The walbro is a better flowing unit than the bosch 040 in the pressure range we use. And you might find one with an install kit for your R32.

The fpr is not needed.

For the nistune it depends of the tuner.

If you get it through him you can get some sort of warranty for installation and having the thing to work properly. It's always more comfortable if you work on something you've done. If I were you I'll get it through him.

But does he accept to work on it ? He might want to sell you a link or a haltech or anything else. Check with him before to get a quote.

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
