i have a R31 skyline with the RB30 and was woundering if it is possible to turbo it?? i.e can you use the intake and exhaust manifold and turbo off the RB30DET and pistons to drop the compression and run some sort of after market or even the RB30DET stock computer? Or is this just a stupid question and should i just go for a conversion??

RB30DET doesn't exist as an actual production motor... But what you *can* do is swap some parts off an rb30ET (the VL turbo engine) to give you a hybrid of sorts. You don't even have to swap the pistons with good tuning and sticking with low boost.

Its worthwhile on a budget if you know your engine is still in good condition.

Otherwise things like the RB20DET, RB25DE or RB25DET bolt fit in fine, however using the gearbox off one the latter two requires some slight mods (tailshaft and mounting)

thanks for the reply,

any of the VL turbo turbo's would be pretty rooted by now so what is a good alternative to bolt on to the VL turbo exhaust manifold or should i look at a custom maniflod? where is a good place to source the parts? Would a stock VL computer plug in and be a good option or should i just get an aftermarket one?

RB20 galleries don't line up, (so i'm told) if you want to do a DOHC conversion, you need to use the 25 or 26 head.

All the information that you need on turbocharging an NA RB30 can be found here:

click me!

You will find a list of all the parts you need in there as well, and a couple of tutorials.

You can use the VLT computer, but it's not a straight swap, you have to wire the ecu so that the R31 fuel pump will work.

As far as all VLT parts being "rooted" you will find that all the ones that are still around have been looked after.

All the thrashed ones went to turbo heaven a long time ago :)

I was talking in no speak english good if he didn't want to turbo the existing engine.. a straight swap with one of the RB2x's was the other option :)

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
