Rb20 Help *turbo*

[nemz]

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

You sound like my clone, even up to the 20psi boost once! Except I have a high flow cat. My next plan is to fit the SAFC2 I have lying around, then find some GTR injectors and a bigger BB turbo - but my budget is just as tight as yours.

[RedDrifter]

Stick the high fllow on. Run about one bar and you will see some good gains indeed. With a good tune of course.

And change you cat to a better one.

Anymore than that and you'll find your injectors/afm will be on the max.

[Sheriff Wan]

Get a tune!!

That will make more of a diff than anything else.

Just get th A/F's and timing right etc etc. Maybe even a map or something like that if a PFC is too expensive.

Cheers,

i just beleive that a remap wont really last long? or am i wrong in beleiving this?'

also you think the cams/harder valve springs would be a good option

[black_32]

if i was u i would stick the turbo on and get a comp even just an safc i think the valve springs and cams would be wasted with such a small turbo

[RedDrifter]

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.

[nemz]

whats the go with the re maps tho? how long do they last? if it will only last for a few weeks to me its not worth the money

[RedDrifter]

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.

ok wat about an oil catch can and an o\il cooler?

[RedDrifter]

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.

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

[nemz]

mmmm, cooler oil = cooler turbo = more power and higher possible boost for my small highflowed t28/30 or whatever the hell a skyline turbo is? would that be correct?

[RedDrifter]

Sounds like a good theory too me

Cooler oil cooler piston temps too I guess.
