I got a r32 very cheap (2000) because it was not complied & needed a turbo to get it complied. I have a friend who gave me everything to convert mine to turbo & its now complied (he went rb25/30 & had it all sitting there) but I'm wondering how hard it will be to make good power (about 200rwkw).I will be doing all the usual mods but was wondering if anybody else here has done it & how much boost can they run etc.

I did the same thing to an old na VL about 6 years ago. it made 175 hp with 7.5psi. made it with a stock na ecu, auto and injectors. It was no power house, but the higher than turbo compression ratio made it snap onto boost at about 2100rpm. it had a very flat power curve and very strong torque. the only thing i had to do was reset the timing to 10.5 degress (because of the na ecu). it made 207 hp on 9psi with water methonal injection. No intercooler.

Wot i'm saying is this, anything with a sound mechanical base usually works fine. Stressing an na engine a fair way may require some careful thought and planning.

I would check rod and piston strength, injectors wont make the 200kw so they will be goin anyway, ecu has to go get tuned or swapped. cams? valve springs could pose an issue.. the list goes on..

Any other thoughts.. :)

Dont hear of the RB20 being NA--> turbo that often.

In a sense it wouldnt be too bad as the RB20 does have a fair hole.

If you limit it to 200rwkw the compression shouldnt becoming a major issue.

Tuning will be the key, as it is for any setup :)

Already checked out the rb20 upgrade thread quite a few times & have 440cc injectors on order,fmic,the car already has an exhaust,have a bosch 070 fuel pump & will run a surge tank,will get a bigger turbo in the next month or so,will just get the stock turbo computer & get it tuned (mine is still running the na computer),will get a split dump soon etc.Just wondering if the higher compression will affect how much boost I can run,will I have to keep it low or decompress it to wind some decent boost in?.

    • Not R7R. Meant to type R&R, obviously enough.
    • Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.
    • I was poking through the R34 wiring diagrams vs R33 and noticed that the R34 has proper headlight relays while the R33 is like the R32 and sends full headlight power through the headlight switch. I'm not afraid of wiring but I really would like to do this in a way that looks OEM (clipping into open positions on the OEM relay box) and also unlike the factory wiring which interlocks the high beam and low beam on the halogen series 1 GTR headlights I want to make it such that turning on the high beams keeps the low beams on as well. Any advice on how to locate the specific connectors + crimp terminals + relays I need? I was thinking one NO relay for low beams and another for combined high + low running off the factory high beam headlight connector. I don't really want to splice into a crusty old probably discontinued factory harness so fully reversible is my goal here.
    • Pretty sure they run the same engine as the Q50 hybrid which specifies 95 RON.  I ran 98 in mine for a while, but it made no difference in performance or economy, so I have been using 95 for the last few years.  I have never hit 6.0L/100km, but have returned mid to high 6 on the highway.  Being a hybrid, fuel economy is a lot more dependant on how you drive it.  At 110km/h, mine never goes into EV mode on the highway, so returns closer to 7.5L/100. urban driving can return low 8s if you are careful or over 10 if you are a bit more enthusiastic on the throttle.
    • About a quarter of what you want to do. It's only R7R, not R&dismantle&replaceparts&reassemble&R. ? It is stock. I already told you, you will NOT have broken those. It's f**king 4th gear for Christ's sake. You just chipped the teeth off.
