turboing a rb30

[al_moar]

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?

just take parts off a vl turbo in the wreckers they wont mind aslong as you pay for what they want...

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
