84 vg30det into a 86 300zx n/a

[Doomie18]

so my friend has 2 300zx ones a 84 turboed and the other one is a 86 n/a. and heres the problem.

it keep burning out coils. and there are so many spare plugs. i was helping him pretty much halfway through this whole project. "was in keywest for half of it". and i have a few questions bout this swap. would it be better to replace the harness from the dash foward so all the plugs would match up. and to add on to that one how extensive would that be. also the turboed engine that he is putting in was orinally auto and he is putting it in the 86 witch is a 5 speed. what would he have to modify to get it to work good. lastly the rpms wont register with the dash and he got a timing ligt to try to get it timed and it wont work.

sorry for the long read trying to help my buddy out.

if he is keeping his manual trans the speedo is a non issue, if you swap chassis harnesses you'll have to bypass the neutral saftey swithc relay in the relay box fomr the automatic car

I believe the turbo engine harness will go right into the n/a chassis with no issues, changing the chassis harness unless you do ti complete tip to tail might cause more work than it saves
