LT1 swap into T-Type

[boostedblkbeast]

I have a 1986 Buick Regal T-Type with a stock drivetrain-3.8 turbo, 200r4 tranny, 8.5 rear. The car is not running now, but I really need to get the car back on the road as soon as possible. Freind of mine will give me a great deal on a 94 LT1 that has just been rebuilt, and is carburated. I was wondering what specific issues I would run across. Will the LT1 bolt right up to the stock 200r4 tranny w/o having to change the tranny mount location and will this also put the motor in the right position for where the stock location motor mount are presently. If the motor does fit in the same location, do I need different motor mount, if so what application. Any imfo and specifics greatly appreciated. But If there is a lot of reworking, changing motor mount position, tranny position, please be clear and let me know, because I still plan to go back to the turbo motor in the future, once it is built. Thanks for any info.

You'd save a lot of money by just rebuilding your 3.8.

But, if the motor will drop right in, I still can't rebuild it cheaper than what I am getting the motor for. Also, the motor is mildly built.

Lt1 in a Turbo buick

MAN THAT'S SACRELIGIOUS!!!
MAN THAT'S BLASPHEMY!!!
MAN THAT'S JUST PLAIN WRONG!!!!
You can always tell a previous small block chevy racer, when things go bad they revert back to their previous habits.

Id say do it if you can fab a manifold to stick your Regal's turbo back on the Lt1

It not about just junking the turbo and going to the V8 for good, it's about having a car to drive, beside I plan on building the turbo motor and what needs to been done now, will just take quite a bit longer than putting a V8, and gives me the time to build the turbo motor the way I want it, instead of just slapping it back together just to get it running. Besides, I am not asking for opions on it, I am looking for the facts of the swap and if any major fabricating is going to need to be done, because yes, I can just rebuild it, but it won't be the set up that I can take 6 months and just build right.

The 2004R will bolt up to the engine as it is a dual bolt pattern case so you can keep the trans in the stock location. Impala SS motor mounts are what you need but I am not sure if you will have to drill the holes in the frame. Maybe try the MonteSS website as I am sure this has been done a lot over there.

your an embarrasment for turbo buick drivers everywere, why dont you just get a junker to drive, instead of putting your beloved buick through all that.

 

[boostedblkbeast]

Sorry, didn't mean to offend the buick gods, but I am not all things buick, I am all things fast. For one, If putting an LT1 motor that I've helped work on and personally seen hit 11's in a Blazer is blasphamy then screw it, but I need a car to drive to work, not to look at everytime I walk down to the parking to catch a ride with a freind. I need it running fast, and if this is what it takes so be it. One last thing, I made this post trying to get the correct information, not to start a debate, so thanks to the people that are trying to help, not piss me off

how much would you sell the car for as is?...i could send a flat bed after it....

damn man, a little harsh there?

 

[boostedblkbeast]

Sorry man not really looking to give up or anything, but as they say money talks, so if you were to make an offer I might consider it. I would just like to drive the car and Hopefulley asap I can put the 109 back in all freshened up and running strong. I don't want a LT1 T-Type, if I really wanted to drive an LT1, I would have just bought a T/A, but I need a temporary solution, and for the price I can't beat it.

you're gonna have to think of something in regards to the fuel system.60# of fuel into a carb isn't gonna work so well,and sucking thru a disconnected intank pump ain't exactly the hot ticket either.

not to jump on the bandwagon here,but i'm sure someone in florida has a decent running stock longblock they can sell you...

 

[boostedblkbeast]

Just to let you guys know, once I build up the 109 block in a couple of months, the LT1 is coming out, so within a year or so, I plan to make that a 396. As far as the fuel issue, I can pick up the fuel pump relatively cheap and I guess I will figure a way to get it out of the tank.

By the time you sort out your accessories, pulleys, motor mounts, fuel system, wiring, etc. you will have more money into the swap than you would in rebuilding the current motor. Heck, if you are hard up for cash, hit the boneyard, find a clean 109 NA block, drill the turbo return hole and slap it in. We paid $50 for a nice long block this past weekend here in Jax.

One more point: it'll be slowww...11s in a Blazer? With a 200 shot or what? In a 3600 lb. Buick, it'll be a 14 second, lousy gas mileage, carbureted slug.

 

[boostedblkbeast]

Just to clear this up, I am getting the motor from top to bottem, everly thing in between all accessaries and so on. Besides you say slow 14's, but the stock grand national is sitting just about that time, right. Besides I know this motor personally, I know what it has gone through, who know's at the junk yard.

 

[Vendor Defendor]

also think about exhaust, you are going to take out you turbo exhaust and put in V8 exhaust just to put back the turbo exhaust, I agree with these guys, you will be spending less to rebuild the GN motor, summit sells rebuild kits for like 300 bucks i think

Call Brett Barnes in Bham,AL,205-428-3857,his shop is called Boost by Barnes. A few years ago he put a FI Lt1 in a 78 T Type. He knows all the ins and outs of these swaps(done alot of lt1 stuff,hybrids,turbos,etc).As far as I can remember it dropped right in with a th350 .HTH

i know i fell asleep and didnt post my just playin thread so hear it is.....Just Playing with you i totally know how it is to need a car, i had to drive a 84 silverado for abhout 9 months after my Mustake got stolen (thanks thieves) it didnt have a A.C. and am i Texas, it always overheats and did all types of crap when ever it wanted to but it was free and alowed me to save up the money to buy my gn (thanks again theives).

Gotta go with the masses on this one. It can be done, but for all the time, blood , and money to engineer this sucker, you're probably better off rebuilding what you have. Especially if this is just a temporary thing. It might be easier to do this swap in a non-turbo car because of the efi/carb issue.
