Hey whats up...

I just wanted to say hii, to all.. And plus i wanna know? If anyone knows or has any ideas, of what i can really do to, modify my ride to handle and increase speed and braking power. To be able to "Eat up Rice Mobiles...".. Thanx. I have 91 88 4 door brough. And looking for mod shops in and around Ontario CA.

Welcome. Aftermarket parts are few and far between for these cars so pretty much everything you do is custom or retrofitted.

Anyway, the easiest way to boost power in a hurry for fairly cheap is to open up the exhaust and the intake.

Intake: pull the stock air box, install a K&N cone filter on a tube, encase in a CAI box to keep out hot engine air.

Exhuast: Replace stock cat with a hi-flo cat converter (dont gut it tho...), and get a hi-flow muffler like a Flowmaster 42583 (single in, dual out):

Suspension: Replace all the factory rubber sway bar bushings with poly bushings. Get a strut tower brace from a later model H-body from a junkyard (this is a bolt-on part, stabilizes the front end on corners: http://www.lesabret.com/phpBB/viewtopic.php?t=4251 <<what it looks like and where it goes).

Brakes: You can pull a 4 wheel disc setup for your rear drums... this is a do-able project but difficult to get everything to work properly: http://www.lesabret.com/phpBB/viewtopic.php?t=2331 and http://www.lesabret.com/phpBB/viewtopic.php?t=1285

Anything else? ;)

you might not want to do those burn outs anymore or you wont have a trans to ride with :(

yeah, 4t50e's were a weak trans. Such a shame that the motors will run forever though

Hey whats up everyone, I hope all is well with all are GM Motor owners...
I have a quick queston: where can i get or find and 91 oldsmobile service manual book!!! which i donèt have to pay ex amout of cash ... lol thankx.. peace out!

autozone sells the haynes manual for $20-$30 give or take. not a bad manual, just not much on the trans. oh and depending on the year look for a supercharger, because the lss had one. maybe you could pull one out of a salvage yard and polish it up?

I thought the car had the 4t60e trans rather than the 4t50e... Im wondering about their interchangability... as far as I've heard the 4t60e is a pretty durable trans??

From everything i've heard the 4t60e has issues with the tcc shudder and sometime a somewhat weak sungear. I'd expect that gm's incredibly reliable 3800 v6 will outlast this tranny.

just what i've heard... i can understand the tcc shudder, but i don't know about the sungear thing.

i have the 4t60e in mine and it shudders going into overdrive and up hills in overdrive. but also sometimes slightly in other gears as well. then again i got in an accident off the end of a t-section and only had to replace the radiator so I guess i had it coming. otherwise they shift very smoothly. i suppose if you take care of them they are pretty reliable.
