vg30 questions

[88minid21]

ok guys i searched and did not come up with what i was looking for so here goes. right now i have a 87 d21 with a tbi vg30 5speed truck and a buddy happens to have everything from a turbo 88 300zx he wants to unload it all cheap and im trying to find out if the intake/manifolds if everything will bolt up fine on my older vg30. i dont want to buy the stuff and find out non of it will bolt up just looking for a low boost set up since i no my engine has a little higher comp then the turbo engine. if anyone has any ideas i would love to hear them.Thanks Nathan

The parts can definitely swap over as the engines are pretty much identical. The only issues you might have is clearance with the turbo, the computer setup will likely be different as the fuel injection setup is different so there's a chance you'll need the ecu and wiring harness from the Z as well. I've never messed with a TBI VG so I'm not sure how different the whole setup is.

thats the one thing im wondering is the intake and such will bolt on just tryen to cover all my bases before i go ahead and buy it, i would be getting the ecu and all the wiring also so its pretty complete just want to make sure it will bolt on for the most part.Nathan

Yeah, everything will definitely bolt up. Just pull all of the external parts needed off of the Z VG and slap them on your VG and you're good to go. The VG block and head castings after 87 stayed the same for most vehicles (the vans got a weird non-interference VG and then of course you have the VG33E in the later trucks but supposedly some parts can still be swapped).

Anyways... you shouldn't have any bolt on issues at all. Good luck!

Aside from the turbo not fitting, no place to mount an intercooler, re-wiring almost everything for FI and getting everything worked out...sure, it all bolts on. It won't run after you've bolted it on, but hey, it will bolt on.

There are reasons that hardly anybody has done a VG30ET swap on a Pathfinder or truck. First is no room, second is $$$$$$ to get it to work. The only turbo swaps I've seen on a V6 are in street-only show trucks with a large amount of money invested in them.
