I was talking to my friends about this. We thought it would be sweet to drop a 3800 turbo from a GNX! inside a Bonneville. But I was wondering what kinda trans and other parts you would need to make it all work well.

Stop it. You're drooling! Hey, Speedguy is a wiz at fitting things into the front end of these cars. He could probably tell you right off what it would take. The only thing I'd wonder about is room for the turbo near the firewall....... :?:

I had the same thought
Actually I was thinking of stroking the 3.8lseries2 then when i found out the gnx unit could be stroked i thought just what you thought. They did it with the v6 fire chicken. Actually if you look around I think I mentioned this way back in the day. LOL old guys do that. There is a company turboing our non sc 3.8l but they will not put out the same bang. I believe if you want to do it it can be done. 600hp would not be a problem. The only issue is in smog areas you are no longer a "car" but a kitcar. kit cars are very hard to pass. Otherwise you can go for it without too much problem.

You mean to say that this won't kill the tranny?]

Hey hey! Taking our ideas, geez... We (ADTR) found a guy out here w/ a GNX engine (all of it) for $125 dollars. God I love Southern California. Going to pick it up on the weekend.

Ok I come from the land of 4x4'* where they make from scratch rear ends that are bulletproof and maintain the very best clearance. This one single solid axle rear end or front end cost $10.000.00 each. why? Well if you want Dana 60 with IFS clearance you pay 10000.00.

So for the front end of the Bonneville 4t60-e or 4t65-e. Well I believe if it becomes cheap enough to put out 600hp there will be a much bigger hp option for the 4t60-e 4t65-e. Actually the 4.6l could be made to run at 6-800 hp so the 4t80-e would be a great candidate for big hp. with a limited slip and a serious unit I can see it eat 800hp. But but but what about the reality of a 800hp fwd. Well the tire set up would be an issue. My idea would have you use an Aurora front fender style with a carefully set up tire and rim setup.

Actually a GNX unit has already been done but it is a great idea the only problem is the need for smog issues. It would be a track only/kit car option for California. I have also seen on this site a fellow Bonneville owner with a bonny sc strapped to a gnx motor.

I am sure more will come and the limits are I believe in the 600hp area. But who would complain about that. Not me. I want 500 out of an Asg 5.0 that would give me the best of all worlds hp with style. I can do it with a single sc or turbo. Or as the ricers like to do.... Nos.


Ok while we are sharing I will suggest the real crazy people who want a Bonneville with hp look to the art of body work. LOL that’* right with simple bodywork I can add rwd and the ability of a gnx or 454 v8 to a Bonneville. No big secret, as for fwd performance i would say 600hp would be a comfortable limit.

having also done the research on this it'* sorta a waste. Buy an SSEi, a chip, and a pulley from a hardware store... SSEi ($3500) + Chip ($300) + Pulley ($5) = $3805 and that'll be a nice daily driver.

FWD + "Serious" hp = Bad Mojo. It'* hard to stop the Torque Steer on a 300 hp FWD car. 400 is nearly impossible.... especially with a 5-speed FWD, but that'* a different story.

And honestly if you're going to build a race car, don't start with an H-body. They're about 3 feet too long and a 1000 lbs too heavy. This coming from a guy who used to race Tauruses ... which are a little lighter, but still have the same detriment. Furthermore, you'll be making serious upgrades to support the really high output of the GNX plant. The fuel system just won't be able to take it. And assuming you either wire up a stand-alone Fuel Injection system, you'll have that added cost. OR, you'll have to patch the GNX computer into the old bonneville wiring harness and I don't think the two electrical systems are similiar ... so you'll have a real patchwork job there. Don't for get new exhaust! You'll need to put at least 3" single exhaust out the back.

If you find a GNX Engine, find a G-body (Is that it for those Monte'* and Regals? Or is it A-body? **** it, I'm a ford guy, LOL) with a standard V6. Drop it in, hell add a 5-speed if you want, wire up the computer and go to town.

GNX Engine w/ Wiring and Computer = $500 in these parts (sometimes more)
G or A body (I don't know which f-ing one it is) = $1200 in nice shape with a V6
new exhaust = $600
So for, about $2300 you'd be running 12'* with a nice set of sticky tires. That'* not so possible in a Bonneville. :(

I hate being the local skeptic ... but uh ... yeah ... I'm going to stick with my position that Bonnevilles are great daily drivers but not so great Race Cars.
