Need Some Help! (Z31 300ZX)

[XBLG20]

i take back my last comment and say drop a VG30ET motor in it (the turbo engine from the Z31) and build that up with bolt ons and can easily net 450RWHP on the stock bottom end. The VG30ET can hang right with the RB and SR and even be a tad better because of the head set-up (more torque) it will also be much cheaper to install the VG30ET

i take back my last comment and say drop a VG30ET motor in it (the turbo engine from the Z31) and build that bolt ons can easily net 450RWHP on the stock bottom end. The VG30ET can hang right with the RB and SR and even be a tad better because of the head set-up (more torque) it will also be much cheaper to first install the VG30ET since it will bolt up and then mod it.

That motor is kinda junky though and there isnt too much aftermarket support for it. The formula for 450 in that is just going to build a rebuild and big turbo. Not to mention they are a bitch to work on. The head setup doesnt have much to do with the extra torque, that has to do with the single cam but the springs and retainers on those are going to let the motor rev out very high as opposed to an Sr or Rb.

Between those id get an Sr20
