Want To Turbo A N/a Neo 25

[33GTT]

G'day guys.

I just bought a N/A R34.

I have everything except inlet manifold, injectors and computer from one of my old 33's.

The question, is, how much of the turbo gear from the 33 will I be able to use on the Neo?

cheers

So you have an exhaust manifold, turbo, dump, and the water/oil lines? That should bolt up without much fuss.

BUT the Neo DET ran a bigger turbine housing, and DE ran higher static comp than the earlier version in R33 (which was at 10:1).

DE spec engines also lack under piston oil squirters and an oil cooler to deal with thermal loadings.

Search and you should also find the Neo DE has smaller inlet ports than a Neo DET.

For me, none of the above add up to potential for a particularly powerful DE+T - too limited by a close ceiling to knock.

That said, if done you could end up with a very flat torque curve with low boost.

besides all that the hardest part of it is the neo DE engines dont have the oil and water gallerie ports for the turbo oil and water lines to just plumb into. so this means some work is needed on the block to make it work.

its not a straight forward bolt on anyway.

a bloke on this forum did it with all the results of his progress a few years ago. it was a 4 door neo de auto i think.

as stated above, you either have to drill the block for the oil/water fittings or get a custom oil line and run it over to the oil pressure sender side & plumb water into one of the heater hoses or other water line on that side.

apart from that issue, everything else will bolt straight up, might need to do a minor mod of the cooler piping so it mates up to the DE plenum/tb but that isn't difficult.

you can use the turbo, manifold, cooler & pipes, dump pipe (front pipe is different), fuel pump

you will need; front pipe, GTT injectors, aftermarket ECU (most people use Emanage Blue/Ultimate)

Thanks guys, pre sold it anyway before I got the chance.
