I found a VG30 engine for my 87na, but the intake is different. It has twin throttle bodies. Can I use it or do I have to use the one off my car?

 

You can use it, but you'll probably want to use the one off your car. The twin throttle body setup will most likely require fabrication to make it fit.

...and from the ashes shall rise a new hope. And it shall be known as "Z". And it will be good.

 

if it is a sohc engine vg30, it will work fine...just swap out to your intake and stuff like that...

just make sure it is a vg30 and not a vg30et or vg30det, as neither will run with much power without a turbo.
