I am picking up a wrecked 01 nb tomorrow for a good deal, running driving car but the body is completely done. I have a 91 that I would like to swap everything over, complete wiring harness, engine, trans, rear end, and dash. Looking for opinions on this swap. I have a lift and pretty much every tool you could need. Engine swaps aren't anything new to me, I have a LS powered FD as well, just looking for some input from people who have done VVT swaps.

What sort of opinion are you looking for?

Why swap complete harness + dash from the '01? Why make more work for yourself then you need to. There's plenty of threads here on the VVT swap into the 1.6 cars.

Well my dash is cracked so that is reason number one, the thought of obd2 to scan is nice, I can use the trans and have an electrical speedo. I haven't looked too much into the forums for the vvt swap how it is typically done.

So you're also going to use the stock ECU? Which one?

You mentioned OBDII.

themetalman

I'll be using the nb. I don't see another way of controlling the vvt

Swapping engine and using existing wiring is a weekend.
Swapping everything including wiring loom and dash will take weeks and weeks.

You sure bro?

themetalman

No I'm not sure. That's why I posted on here for input, I guess I will do some reading about the vvt swap using existing wiring.

Have you read the VVT swap megathread?

If not go do it before you ask any more questions.

themetalman

They expect you to use an aftermarket ecu to control vvt. So far the only small problem I see is doing the fuel system but that will be easy, just use an aftermarket fpr and set it to 44 pounds and utilize the return line. Running stock wiring should be cake. My last swap ran me 5 days from start to finish. I really can't see this being a huge pain.

VVT ECU expects a constant 60psi of fuel pressure. Its not 1:1.

I swapped a complete VVT setup out of a 2001 car into a 1994 a few weeks ago. Needed OBDII for emissions when it becomes an Exocet. Pulled the complete NA harness and replaced with NB. Had to drill one extra hole in the center of the firewall for NB engine harness. Runs stock ECU from NB.

It was not terribly difficult. Took a bit over a weekend.

You can swap over the NB fuel lines and the NB fuelpump/tank unit. I did not swap the fuel pressure sender and got a check engine but other than that it worked great.

Fuel lines can be installed without dropping the tank but it's not recommended.

PM me if you have questions. It's not as bad of an idea as people are leading you to believe.

themetalman

Thanks, I won't need to have obd2 but I want it. I have it in my rx7 and like to just plug and play. My plan is to strip the 01 of everything, part it out and keep what I want. I need to look into how it is tuned with the supercharger. They guy I got it from didn't know anything about it.

themetalman

If that's the case I can just run a corvette fpr and be good.

slug_dub

If you want to supercharge properly you need to change over to an aftermarket ecu anyway right? Yes, yes you do.

themetalman

I'll have to dig into the car more to figure out how it is controlling fuel and timing for boost. If it doesn't have anything (which I doubt, it runs just fine, granted I have no wideband in it) I'll just do a vvt swap and sell the supercharger.
