Turbo Buick G-Body Engine Swap

[86MonteSS]

Hi,

I have an 86 Monte SS that I'm looking to swap a GN motor into. I know at this point, most people would suggest buying a GN, but I have the entire suspension/body done on the Monte w/ lots of goodies, plus an upgraded cooling system.

I've been debating on getting a 3.8 N/A block, putting a 4.1 l crank in it and rebuilding it and the heads w/ a GN rebuild kit. This leaves the problems of accessories and wiring (I'll get all the turbo plumbing custom bent or buy used). Are the accessory brackets in the same place on a non-turbo motor?

Any other advice? I already have an efi tank and walbro pump ready to go, and I can get the turbo for a pretty good price.

Thanks for the help.

Actually I think you'll find lots of people who think the conversion you are proposing would be very cool. I can't offer a lot of help, but keep checking back because others will. Welcome aboard.

I can fill you in on all the ins and outs and what you will need to complete the swap. I did this on our Monte SS and will be doing another swap soon.

Your best bet is to find someone selling a complete setup out of a GN. You will see them in the for sale section here from time to time. Complete engine including turbo and intercooler with the wiring harness. Expect to pay a minimum of about $2500 for the setup with 90,000+ miles on it.

this is just the beginning, i only looked for a minute or so.

item #2408234153 if the link doesn't workgn motor at EBAY.com

just thought I'd help

I think it's a GREAT idea. If I could "do it all over again" I'd have kept my 86 SS (hence my screen name) and put a GN drive train in it. Handled alot better than my GN and looked meaner. The Buick is far more comfy though.

go for it dood. I was gonna swap a motor in my Monte, a 383 stroker or a 3.8 Turbo, but wussed out and bought a 4th gen.

Should have never made that mistake.

Not certain, but I believe the accessory placement/brackets are all different between turbo and n/a motors, because the turbo occupies the whole passenger side of the motor and the IC and piping cover the front. So all accessories are on the driver's side of a turbo motor.

You'll also have to source an intake manifold from somewhere, along with headers, oil supply for the turbo, turbo-specific engine sensors, and misc. electronics and wiring. This is why most people recommend buying a complete turbo motor and wiring when doing hybrids. All the little pieces bought separately can add up to big $$$ real fast. In my case, I swapped everything over from a beater '86 T-type that I bought for $1900.

Otherwise, it sounds like you're on the right track and you've done your homework. There's lots of experience out there on these kinds of swaps. Sounds like a great project!

Your idea is a good one.I am thinking of doing the same.
Anyway.........
I have a complete engine that I may sell if you're intersted.
Or,if you just need some parts, (intake ,headers,brackets,ect) let me know.
email me direct. Don't reply here.

I think we need some kind of removable whistle tip to take to car shows and let people think we're really THAT stupid. Or let the older folks go "what the hell was that" as we scream down the track.
