i have have a fairly stock rb20det, basically all it has is a walbro fuel pump, 450x300x78 fmic, stock turbo, pod, boost tap, 3.5 exhaust with stock cat(yeh i know lol im too lazy to get the f**r off* otherwise id have a new one on by now, service it every 5000km and it runs like a dream, no probs cept vacuum pipes splitting on me all the time, running turbo on 14psi never pings, runs smooth as a mother! had a few probs when my spark plugs got to old was misfiring a bit, but now ive accidently ran stock turbo on 20psi! and i didnt notice for like 3 days cause my brother mainly drives it, put it back down to 14 psi still fine! runs like a dream

any way! so had everything checked out and the engine is top notch, so im just wandering what should i do next, i have a high flowed r32 turbo sitting in my wardrobe i was thinking about installing it, i was just wandering.. i know the stock turbo's are watercooled correct? should i put in a oil catch can and oil cooler?

also was thinking about bigger valve springs and cams, and no i dont have an ecu

also any othe rsuggestions on what i should do on my tight arse budget! ive managed not to spend over 1000 so far, got her completely stock :)

Stage one cam 256 deg 8.5 mm lift (tomei) would help no mater the turbo but you wouldn't need to change the valve springs for this cam.

If you wanted to intall the high flowed rb20 turbo the cam would be only benificial but not a necessity.

In the end you will still need a remap/tune. Regardless of the turbo you go with.

A stock r32 ecu is fairly easy to remap for someone in the know.

OK where did you hear that?

A remap is permanant.

I'm running a much larger turbo,FMIC, 550cc RX7 injectors and a Z32 afm all on a stock ecu I remapped well over 12 months ago.

An ecu will self learn to a point but it has a base map to start from which is what people change in a remap.

Self learn is mainly ignition timing in a selected part of the map and some minor fueling in the closed loop area of the map. Other than that it will run what is is programmed/remapped to.

Oil catch can is a good idea. Though a healthy RB20DET breaths sfa. :)

I only have one because my olod motor was so stuffed. I could fill it up in one night. :P

As for an oil cooler I dunno. Never had one and never seen any used. Probly only nesaccerrywhen racing I guess.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
