I own a 1998 Lumina LTZ it has the 3800 series II (3.8L V6) 4 spd Auto on the floor (side console) I'm looking to REALLY mod it out!! I've found a site; http://www.thrashercharged.com As you can see they have performance parts for GTP's. I've e-mailed this site and they said that i can perchase the parts from them and they should fit. This is a list of things that i want to do to my car I just need to know if any of this is do-able.

Bored and sleeved to original size
stock pistons, crank, and piston rods
3angle valve, ported, pollished
DBL coil titanium valve spring, bigger valves, titanium pushrods, hi-perf. roller rockers
Crane Cam w/ matching hi-performance Hydrolic Lifters
Super charger??? not sure what brand ( 10-15 PSI)
Intercooler
Larger Throttle body and intake....
hi-performance / larger fuel injectors and larger fuel line
newer headers with 2 1/4" TRUE dual Exhuast coming back to TWO Borla Mufflers.

Ok now the web site that I posted up top sells a shift kit for my trany BUT, here is the ultimate question that I need answered!.......
In 1991 Pontiac put out the Grand Am GT with a 5spd manual with a 3.1 liter engin. I must know, it is posible to cut my firewall, mount a clutch and do away with my current floor auto shifter and install a short shifter 5spd. Please reply to this with what ever you think!

Hi Mitch, I too have a Lumina LTZ. I also would like to increase its performance but have not had much luck in finding companies that make parts for it. As to your question, I don't think a 3.1 tranny will bolt up to the 3.8. I could be wrong, but the blocks are different.

I also have 1998 ltz and i'm also lookin to get more performace out of the engine, let me know if you have any luck. if you're looking for ground effects http://www.razzi.com/ has a set for a ltz that aren't too bad.

Hmm sorry i didn't view this post sooner... it was one of my first posts when i started here, and i didn't think that anyone would check it out... but...i have learned ALOT since i made that post.. and i found that;

There is NOT a 5 speed that will fit the 3800

You can do a 3.4L DOHC swap that,stock, puts out almost just as much HP has the 3.8L and DOES come in a optional 5spd Manual Transmition,(was the GTP back in 93 or 94 i beleave before the 'gtp' was a Supercharged 3800) and alot of mods CAN be done to tha engin as well as the 3.8L.

Of course, like i new before, ever engin can have some form of forced induction, if you want to travel that road *at high speeds mind you *
so the 3.4LDOHC is no exeption!

Lastly, get head! No not the head that your 2dolla hooker, or your fine ass asian G/F gives you! But the head work that can be done to *again* ANY vehicle.... port,pollish,3angle valve job, bor and fit larger valves,dbl titanium springs, ROLLER rockerarms, new pushers for your head and new shuvers for you Pistons... you can get a full unorthidox racing pully for most cars too...and fully ballace your crank and you have a complete engin...

Forgot to mention, Cams,cams, cams... Cranecams.com all i got so say about Cams...

NOW,lastly, there is several ways to knock down that 1/4 mile time with simple shit, first, get AAA, then dump your 50mile blow-out spare, and your 'gettin-your-head-crushed' jack that already DOESN'T work.. notice your "dual exaust" :finger: f*ck it!:finger: the one on the left is NON-funtional..chop and patch (with a piece of metal and a welder, we dont need more noisy ass cars) there goes about 80pounds off the...ass of your car... litterally


ok well now that i have told you both how to completely F'up you Lumina much how i'm currently working on mine.. HAVE FUN!
