I am thinking about purchasing a t25 off of a 300zx. is it the same turbo as the s13 t25? i heard that the flange is different. please let me know.

Nope actually the 300ZX uses a pair of TB022's

they are 4 bolt downpipes oposed to S13 being 5 bolt
compressor inlet and outlets will need clocking. / adapter flanges.

and they are small. they hold 18psi nicely though

More trouble than it's worth to find a proper downpipe and such. If you're bent on finding an undersized turbo, find an s13 t25 instead.

Yeah but on a small turbo like that it pushes about the same amount of air as a T28 would at like 11-12 psi.

PSI doesnt mean shit its the volume of air that the turbo pushes that matters.

yeah they can do that much but usually for us Z32 guys we only do it with race fuel, since the compressor is a little out of efficiency range.

They can maybe hold 18 psi on half a 3L engine(1.5L), but there is no way they can do that on a 2L SR that revs up 500 RPM higher than a VG30DETT.

Short story - they're smaller and flow less than an SR T25.

They make excellent doorstops though.
