hi everyone

i recently bought a 1987 turbo manual skyline (2 door) for 6000. is in excellent condition with new paint (white) and has an r32 turbo on it.

i'm completely new to the whole jap car turbo thing...my previous cars have all been classic aussie v8s and though i still love them i just cant afford to fix things like rust and hunt down non-existent parts anymore, so i decided to go the quicker, cheaper option!

so yeah, as i said, i dont know much about these cars, just what i have read on the net about there build, date basic engine specs etc.

the main questions i have are regarding exhaust systems, engine and turbo upgrades, and weak spots in the cars.

exhaust systems. Does the car need the huge cannon on the back for power and/or stable axhaust flow or can i remove it and put something more conservative and quiet on it without losing too much power? if so, how much power am i looking at losing?

engine upgrades. how much will it cost roundabouts for an engine reconditioning. is it worth it or should i just get a new engine? can i put a turbo engine from a later model in it? how much would an engine from an r32 be? i think my car is only a single cam? how do i confirm this?

turbo upgrades. as i said, the car has a turbo from an r32 on it and although the guy said you dont have to do any mods, is there anything i need to be aware of? are they as compatible as he states or will i need a bigger radiator, intercooler, adjust anything...? how much is a new turbo/bigger turbo and what modifications will i need to make to the engine/driveline so that it doesnt blow up?

lastly, weak spots. do the r31s have any trouble spots, leaks, rust etc or malfunctioning parts that i should know about?

thanks

Daniel.

I don't think cannons look good on anything, just get a proper flowing 3" mandrel bent exhaust and high flow cat and that should do you for your exhaust needs.

I have just that with twin 2.5" tips at the end and I reckon it sounds better than if it had a fart can on the end.

Engine rebuilds start at about 3 grand for an RB20 I think, though I'm not 100% on that. Depends on what you're after. If you want a stock standard rebuild then it's probably worth putting something better in there. RB20DET Silvertop engines from R32s are cheap and a good upgrade, they just lack torque.

I have an RB25DET in mine, I rekcon they're the best all round upgrade for a 31.

The swap to any other RB series engine is relatively easy, it's usually a matter of bolting it straight in onto the standard crossmember using standard engine mount, custom gearbox crossmember depending on what box you're using, and a custom tailshaft, again depending on if you're using a different gearbox. Wiring looms need a little bit of playing with as well. There's a few other little bits & pieces depending on which engine you're putting in. Try searching for engine conversions on this forum or the R31 forum and you'll get more information than you can read in a lifetime.

A popular upgrade for RB20s is the R33 or R34 RB25 turbocharger.

If you've got the single cam engine that you seem to think you have, then I wouldn't really bother putting any work into it and instead put something twin cam into it.

They're prone to rust in the A pillars because of the water channel design, like a lot of cars are.

    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn
