Lots of people have considered it, as stated. There are many reasons that they are not done more often. As with any engine swap into a car that didn't come with one (or one based off the same block) there will be issues. - 3.4L, 3400, 3500 V6 swaps are done because those motors either came in the w-body, or they decend from a motor that did. - 3800 NA and S/C swaps are done because the motor is inexpensive, has a large aftermarket, and many people have done the swap, so it is easier and cheaper to do now. - 4.9LV8 swaps are not done much cause you don't get much power out of it compared to the above swaps. Also almost no aftermarket - 4.0L Northstar V8 swaps are not done much cause they are expensive to work on, have some major issues (head gaskets) and don't really have an aftermarket. - LS4 swaps as stated are a wiring nightmare and still very expensive compared to the others. - LS1/350/305/etc swaps are not really done because while you can use some of the aftermarket for the motors, you still have to do custom mounts and exhaust routing, and even if you do get over 300hp, you'll be swapping transmissions every couple burn outs, or dropping some coin on a built trans. And that is actually one of the biggest reasons that you don't see much over 300hp in a FWD GM car is that to get the power from the motor to the wheels, you have a lot of parts that were never designed for that HP that like to break that you would have to fix constantly, or find upgraded (read as Expensive) replacement parts, and even those are not bulletproof. I have a friend who had a 300+ HP bonneville with a 3800SC and he went through 4-5 built transmissions before deciding to part the car. There is a difference between no large modification to GM and no large modification to a backyard mechanic. GM made a RWD bonneville powered by an LT1 for the hell of it. in the end it consisted of parts from 4-5 cars, all of which they had access to. Also, if you read the article on the Z50 (HERE) you will see that there were no modifications to the body, but they "came up with a special short water pump and reduced the back of the motor" to get it to work. It was also a 4 door, 5 speed AWD car. Yeah, the fiero guys are a good resource for some of the stuff, like getting it to work with certain transmission, but mounting it in the car will be w specific. I believe these are measured in couches. They were fairly large monstrosities that mounted the motor longitudinally, but powered the front wheels. They were also hooked up to Olds 455ci V8, which is a big block. And lastly, if you ever though the 4t40 trans was weak, wait til you see one of these. They were not very reliable and did not like increased HP at all. There's a reason Leno put his toronado on a Corvetter chassis to make it RWD. With all that being said, if you are serious about doing it, go for it. We will help in any way if we can. Oh, and here is a V8 swap on crack: http://www.ls1.com/forums/showthread.php?t=71662&page=1

@pwmin thanks for the pictures looking to make this upgrade on my '92 lumi

Ya, that’s not how a name plate from a manufacturer is done! Ever! A name plate, in this case the Grand Prix, is determined by a manufacturer body change! Not a platform change or a discontinuation & then a revival & not even a drivetrain change. Case in point the Camaro was discontinued in 2002 & then revived in 2010. 2002 was the 4th Gen. 8 years later in 2010 the 5th Gen was resurrected. The OGs in their mind didn’t want a FWD vehicle to be associated with their RWDs. But irrelevant of what they want or how they want to spin it, the Grand Prix is one name plate line be it RWD or FWD! Fact!

I have a Plethora of NOS Grand prix trim, window seals, moldings. Most of them are still in GM Factory packaging I have part numbers for most of them some don't have part numbers and I've tried to get some but have come up short. Text me if you have any needs at 763fourfour1 795five. Included with trim and other NOS parts is a center piece taillight with the word turbo instead of Grand prix I can provide pics a lot of these parts are posted on Facebook already under my profile. If you search GM NOS or the old part number you're looking for you should find my profile and can scroll through the parts I have listed please let me know if there's any interest in these parts.

I'm going to attempt to attach photos (yay it worked, but they're not in order). I'd say it loses about a quart a week. 182,000 miles, plan on taking it on a long trip (~1300 miles). She's all I got right now I'll try to explain. There's a recesses area just to the right (perspective of someone standing in front of the hood/engine) of the plenum?/throttle body?, oi the thing that says "3.1 Multiport FI". Basically just behind (same perspective) the filler cap. It's oily down in there. It leaks out apparently, then travels toward the rear of the car. You can see the pathway in one of the pictures. Sometimes it even seems like coolant comes out of there also. No oil is not smokey or anything like that, looks normal. Assuming it is a crack, I'm planning on getting in there, cleaning it thoroughly, then jamming epoxy putty in there. I should think it would hold for a while. Oh it's a one way trip

Yep thats what it is. Those o-rings get hard and brittle and crack over the yrs letting oil out.

o-ring on oil pump drive shaft? [ where distributor would be ].

Has anybody ever considered a v8 engine swap into a gen 1 w body? Maybe a 4.0 and 4t80 from an olds aurora, or even a caddy engine, seeing as how they are ff layouts too? I've been reading a lot about w bodys and performance upgrades in interest of my own, I've got a 91 lumina with the LHO 3.1 and even with forced induction the biggest number I've seen doesn't even crest 300 hp, and to be honest that's dismal to me. Any thots or support?

There used to be a company that would take old caddy 4.9s and open them up to 5.0 and install them. company was called ASG if I remember. Why they picked one of the more boring slow caddy v8s I'll never know though.

Anyone know the dimensions of those FWD v8`s they dropped in the Old Toronodoes or Cadillacs? probably be too heavy for realistic use

This. For simplicity of swap, modability, and power. Or you could go the 60* route and turbo one for similar results. IMO any fwd v8 isn't worth the swap...

Theres a northstar swapped monte for sale!

The only feasable FWD V8 swap worth doing is the northstar (I know theres the LS4, but the electronics involved with that swap is overwhelming.) A good community to watch is the Fiero guys. If a swap is possibly, they are doing it. very few guys do 3.1 Turbos Some guys do 3400's Some guys do 4.9's A few more do 3.4 DOHC's and Northstars but most of them do 3800 SC's for the simple, bang for the buck swap The are kits that allow them to put LS1's and the like in fieros, but FWD LS1 isn't the same as mid engine rear drive LS1 In all honesty, buy a super cheap j/y 3.4 DOHC for a couple hundred bucks and jam it in there. 200 hp vs 135 hp for your 3.1 Or a series 2 3800, even an N/A one and top swap it or turbo it later.

Gm did a 305 swap into a lumina, idk what trans they used but I know they did it, they called it a lumina z50, and the article I read said that no large modification was required. I by no means claim to be an expert but common sense dictates to me that a 4.0 swap wudnt be any harder than a 3800 swap from a newer vehicle with obd 2, but idk if mounts will mount right up, if it will fit, if there are driveshafts compatible even for the swap. I don't plan on doin this myself but I was putting the idea forth curious if it was ever thot of.

What car(s) does this guide apply to? I have a 95 Lumina, with drums and I am doing a rear disc upgrade. I plan on buying new brake lines for the calipers, so I need to remove the flex brake hose, where it meets the solid brake line to the master cyclinder. Do I need any special parts/tools to do this? I assume i need flex brake hose from a 95-99 Lumina with rear disc. Also, do i need new bolts or bushings between the knuckle and the link rods/trailing arm?

i got an ebrake assembly off a newer car and got new front and rear cables from Advance (pn's C94727/8 - rear and C660173 - front). for the brake assembly, i used one of the side mounts and welded on an appx. 1.5" spacer and used the rear top mount by bolting a small flat bar and put a spacer on it. i know its kinda ghetto, but it seems to work. i may make it better some time. here are the pictures: http://smg.photobucket.com/albums/v476/pwmin/91%20Grand%20Prix/rear%20brake%20upgrade/
