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.

    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
    • I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.
    • I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?
    • I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
