First off i'm a new member to Boneville club, But i have been researching bonnevilles for over a month now and have been following this thread very closely. I was aprehensive about joining since i felt i didnt really belong here (owning a 94 Grand Am Gt with a 3100) but the secret is that i have a 93 bonneville ssei, with no body left on it and a good 3800 */c sitting in it that i just recently purchased for 300$. Also as another piece of info the 3100 died after 145,000 miles. I pondered junking it or parting it, the engine wasnt really modded, it was just painted electron pearl blue metalic last year and its been lowered and got a 1200 watt infinity system in it. The the bonneville came along. You all know what im gonna say next.
Take a stock 205 horsepower engine and stick in a grand am, that'* 800lbs lighter, but if im gonna do that i should at least invest the money into the engine to push it to 300hp. So after much research i found a few parts that would help me out here and there, jet stage two chip from adtr, 2.2 pulley from pulley boys, port and polishing seems to be big on everbodys wishlist.
Now everybody has heard the idea of putting an l67 in a smaller gm, has it ever been done? Not that i know of. I've looked thoroughly into it, i've only found one person who even claimed it and it was stephen'sga on http://www.gmp.homeip.net/
. and he has no proof and he admits that the only pic he has of it is photochopped.
So why do i think i can do it, because everybody tries it with a series II, they wont exept the 35hp difference, and dont relize it can be made up for. Fact is that in 1992-93 GM put a 3.3 in a Grand Am, a 3.3 for those of you who don't know is made on a 3800 block, so therfor it fits, and seeing as how my grand am is a 94(same body style and interior, and most importantly engine copartment) makes this a relitively easy swap.
Heres the facts:
I have the wring from the bonneville
The 440-t4 in a 93 ssei, is in fact a 4t60e close relative, its so close it bolts right in and the shaft will work to.
The series I isnt that different from a series II
If a 3.3 will bolt in then if my car were a 93 a 3800 would bolt in but my car is virtually a 93 so, who cares.
and furthermore to me this looks completely feasable, if im wrong please correct me.
So i guess ill end up belonging here with all of you, your all very knowledgeable about your vehicle, and Dr. Jay I've been following your post from day one. I know everybody out there with a series one L67 appreciates your dedication into your project and is following this thread as closely as i am.
I'd appreciate anybody input into this matter and id like to hear what you all think, and maybe Dr. Jay can give me some mod tips.
I' wont be starting on this project for a week or two, because my girlfriends upcoming graduation will have me tied up, ya know relatives comign and staying here for a few days or so, and party prep.But when i start it i will post a new thread on it, im also working on gathering some old pics of my car and throwing up a website for everybody to check out
Thanks Grand Am Man
