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.

    • Hey keep the ideas coming, I'm always keen on projects! But, problem fixed!  I got a cheapie ozito scope from Bunnings and had a good look in and around the bearing and sensor hole. I couldn't see a smoking gun but the bearing looked a bit strange, especially when comparing with a new one. I thought the cover had come off the bearing magnets.  Sorry for pics of a screen, I didn't have an SD card.     Good thing I had the old one to inspect. So, given I'm like a pit crew with wheel bearings and luckily I had a spare bearing because I f**ked up my parts order, I decided to just smash it out. Got the old one out in about an hour. So much easier when the parts haven't had a chance to rust together yet. 😂 And, well, found the problem.    In the second pic at about the 8 o'clock position, you'll see what I think is the tip of the old sensor.  The new sensor has definitely been rubbing but it's all intact, just a little shiny so I'm hoping it's fine.  The car brakes perfectly now and no errors.  I think the job took about 2.5h in the end. 👍🏻 I really appreciate the help in here as usual. Thanks guys.
    • I was only looking because I saw some drops on the ground but it wasn't alot. Recently had it serviced will ask the mech to confirm. Find it strange that it looks standard though, can see in another photo of a random box 
    • So...not sure if you know if that has always been there or why you went looking. It could be old damage from a clutch explosion, or even just the gearbox got dropped somewhere along the line. Basically, you should seal it up to stop oil and dust getting into the bellhousing, but it doesn't matter too much and is not structural. I'd suggest something like a glob of JB Weld. BTW what gearbox oil are you running, I would guess the breather has been spewing it everywhere.
    • Hey Duncan thanks for your reply. Sorry mate I know the photos are shit.  Took another photo for reference. Seems the casing does have a hole in it looking on the net, fluid seeping out. Added a photo
