Ebay Turbo difference T3/T4 TO4E

[RB30E+T]

I'm going to stay away from the ebay turbo's now & I'm thinking about using the turbo off a 1985 Z31 300ZX vg30et single turbo motor as it's basically the same as the vl's stock turbo. Should go alright with a 9:1 compression RB30.

Dude.. go a standard vlt setup... i cant stress it enough.. Unless u have a good understanding on whats going on.

or if you do decide to run another turbo leave it on 7 psi with that hi comp cause 7psi would be like 12-14psi on a hi comp

so bow my highcomp on 10.5 is roughly what man>>16-18psi??

And the 300ZX turbo would b 25 years old so it will require a rebuild which is $$$$$$

 

[nasty1]

7psi hi comp is near enough same as running a low comp engine on 10 ish psi

The t3 on the Z31 1985 300ZX is the same turbo fitted to Vl's anyway & the car it came off is only 1 year older than a 86 model Vl. The 300zx that it's coming out of has only done 114,000km and looks to be in top nick for it's age. It's the one that has oil and water, not just oil feed. Surely it has to be a better turbo choice than a Chinese copy.
