I'm installing a Buick GN 3.8L Turbo in a 1988 S-10 4X4 with a 700R4 can anybody help me with this engine swap, as to what is needed and what has to be done. ie headers motormounts oil pans and so on if anybody could help please let me know
Thanks  

Generally you do not use headers with a turbo because you have to route exhaust to turbo. That engine should have same bolt pattern as a 2.8, 3.1 and 3.4 GM V6 as I recall (I am not 100% sure though) otherwise it should have a SB pattern if not. You need to find the correct 700R4 bellhousing to bolt to it. Otherwise this is not going to be a realy nasty swap. It will require some fabing of mounts and wiring for engine but it should be easier overall than a V8 swap. You are going to have to watch/measure clearance for turbo routing and location.  

It has the standard B.O.P. bell housing the 2.8-3.4 are different. you'll need a adaptor to to use the 700r4 or use a th2004r it will bolt right up and will also survive quite well in the light vehicle.

I had a 79 luv I put the 3.8 turbo in with a th200 then swaped in a th2004r, it's not a hard swap at all for the luv. On the s-10 you may run into a problem with the crossmenber and the oil pan.
headers aren't going to be an option with the turbo. you'll probably also end up making a new exhaust crossover pipe to fit.  

MAN!!!YOU ROCK,THAT TRUCKS GONNA BE AAAWWWWWSSSSUUUMMMM! AHEM..THINK OF THE POWER YOU CAN MAKE WITH THAT LITTLE GUY,RUMORED IN THE DAY THAT YOU COULD GET A THOUSAND HORSES ON METHANOL,DONT KNOW BOUT ALL THAT, BUT WITH SOME TWEEKS,DANG! NOW THATS WHAT I CALL INNOVATION IN A RIGHTCHUS, RIGHTUS,WELL YOU GET THE GIST.THINK BUICK HAD A 252 V6 IN THE TURBO RIVIERA A 4.1 OR 2 ANY HOW HOOK US UP ON THE PICTURES!!! GOOD WHEELIN TO YA,PS..INTERCOOL.  

my little luv ate corvettes for lunch....just as the GN's did when they came out.  

Sounds like a pretty cool swap! Keep us updated on your progress!  

You guys have all the fun cornered! i cant even imagine the total rush it must be or have been to drive the killer monsters. my bubby had a courier with a 306 ford and c4, took me one ride to figure that these little meth trucks were to much for me! that is the strait no pooper!,when he got slidways at 80 in second i was to scairt to say nothing but ooh,ooh!he wound it up to 8500 in second, daaannng!!!that little GNS-10 IS GOING TA BE THE RUSH OF THE YEAR FOR THE MAN, very happy wheelin to ya!  

Thanks for the reply so i would be better off to fabricate my own motor mounts, instead of trying to use OEM style mounts and jerry rigging it to fit  

Thanks for your reply.Since it is a lowered 4X4, I managed to install a CV drive shaft from a S10 cyclone. I don,t have the engine in yet but gona try a dry run. Would this drive shaft be in the way of my routing of exhaust tubing and would it be worth while to fabricate my own exhaust manifold out of stainless steel.  

Thanks I do have pic of what it started as and what it now looks like but don,t know how to upload it to let people see can you help  

put it in the readers rides, you don't need a link or host to post it there.
