Hey fella's, just had a thought.
They say the JZX100 2.5L 1JZGTE vvti single turbo model has the largest turbs of the toyota range. It has a T3 flange on it too which means it'll bolt up to a standard rb20/25 exhaust manifold. Obviously the dump flange is different to a gtst turbo, so fitting one will require a different dump and possibly changes made to the intercooler piping.
So does anyone know if they're any bigger than the r33 rb25 turbo? Flow more etc? Good/crap upgrade/downgrade?
It has the much hated ceramic turbine wheel, and can't safely be boosted above 14psi much like the skyline turbo's. Buts thats all I know.
I'm probably answering my own question, but i suppose it comes down to if it does actually give an extra 15rwkw, is the price you pay for the turbo, dump fabrication, front pipe modification, intercooler piping modification, oil and water fittings actually worth it? .......Probably not.
