R34 25GT NA - Turbo?

[Alfie123]

Gday guys, I' ve owned my R34GT non-turbo for a few years now and have always wanted to try and get the car turbod I've been told its not worth it? what would be a rough cost for it to be with the full set up and is it worth it or just leave it?

 

Cheers

"Worth it" depends what you want from the car....if you love the car and want to keep it long term it is probably a good option.

If you just want to get to Woolies faster, you would be better buying something more modern.

It would probably cost a few thousand, even if you find second hand factory turbo parts. You need

Exhaust manifold

Turbo

Water and oil lines for the turbo (and places to tap them into the existing systems)

Dump pipe to suit (often custom)

Exhaust to suit

Intercooler in intake

New ECU and tune

Larger injectors

Boost control

Depending on power goal - new clutch or auto trans upgrade

probably plenty of other things I haven't thought of, but that would be a few thousand to start.

Add to the list;

Fuel pump & wiring.

LSD, because single peggers are weak.

Brakes.  should have put these first.

Spare money for new gearbox when the NA one breaks. Probably spare money for tailshaft mods to put in proper turbo box in place of NA box to prevent repeat breakage.

OR go full out:

• RB30DET
• Samsonas
• BBK
• Mechanical LSD
• Full re-wire, traction setup, the works

Or just buy a fast modern RWD turbo like a M2 Comp.

Or buy my car.

That said, I don't think I'd sell, because I know what it'd take to do it again. Really you're buying/building a complete car from scratch that just happens to have the body you like. It is never 'worth it'. It is far more sensible to sell it as is, then go buy a Mustang. MUCH easier, and cheaper too.

Let's just say that it is probably more "worth it" now than it has even been. Given the relative unavailability of GTTs and the elevated prices for them if you can find one for sale, doing the work required to turbo an NA car is not as financially silly as it used to be.

It's still financially silly. Just not as bad as it used to be.

Better option is still to do what Greg did. Put an LS in it. Or put a VQ37 in it (if you can handle the obscene noise they make). Add valley mounted intercooled supercharger for boostiness without needing to plumb up turbos. Hopefully add some more tasteful noise to drown out the exhaust too.

No, recently I saw someone put a R34 N/A up for sale on FB. One of the swap offers was a 2013 370z. That is the smart option.
