Cadillac Seville / Cadillac Eldorado Forum Discussion, I need more power in Past Cadillac Vehicle Discussion; Hi I'm new around here and I was wondering on how to get more power in my Cadillac STS. Also ...
Your best bet is to buy another car. There is limited aftermarket support for performance mods and most everything you'll find is snake oil BS crap. GM got about all you can get from this motor from the factory. You can drop $1800 on a Corsa exhaust and maybe get 5 HP. Go find something powered by a Chevy 350 and mod to your heart's content. N* is not a motor to play with unless you have deep deep pockets and infinite time.
Basically: There is NO aftermarket support for the FWD Northstar Seville/Deville/Eldorado package.
Look at www.corsaperformance.com for a cat-back for your model, then look it up in www.autopartswarehouse.com. That's IT for mods. There are a few DIY tricks in here, you just need to search. A so-called "CAI" is a waste because the car already has a perfectly adequate cold air system straight from the factory. As chubbyranger posted, there ain't much out there.
Go up to the top of the page, in the black bar, and read the entire Cadillac Technical Archive and then begin wading through Northstar Performance down below.
EDIT at 1057: You have a 1996. CORSA does not make an exhaust for your car. You might contact Wester's Garage to find out if they have developed a mild tune for your ECM ($350 ??) - it can't be done to later models, though.
I really wish there was more aftermarket for the caddy's like ours, but then again it's plenty fast enough to get me in trouble, looks great, comfortable as he!!, and I save money by not being able to do many engine mods lol
You're not riding around in perfection: far from it. You're riding around in a car that has zero to slim aftermarket parts appeal. A company, any company, that did a development on some widget for a FWD Northstar would go broke on the R&D alone, not to mention building the thing for the very few who would even buy the new widget.
perfection of crummy engineering! Total money pit!
GM was my favorite until I bought this caddi in 02. You would think with how expensive caddis are, the parts would be superior in strenth and design. While things look cool,and pretty, they designed them to fall apart too early and made it as difficult as possible for a human to work on.
Very dissapointed with Cadillac and GM.
ps-- keep an eye out for blown head gasket! It happened to me 2, yes 2 times! 2 different engines.
Whats really sick, is after all that I still love my car......
Mine isn't particularly well built but it hasn't cost me any more money in the past year and a half than I would have expected it to. Mine already had motor work done to it before I bought it, but the car really hasn't been so bad. Seville's are a mixed bag for the most part. Some don't really suffer too many issues and some are full of problems from the start.
Then again, I paid 1/5th of the original $51,992 sticker.
You take the good with the bad with these northstar models, I sold a 94 Eldo 2 years ago with over 184k on it & no HG issues!!! So some last and some dont, you roll the dice and see how it does, one things for certain, problems or not sure is enough of them on the road & the Cadillac brand still going strong as Hell!
Seems odd to me that so many on here say you can't get any more power with an aftermarket performane exhaust and/or intake when I clearly remember reading once in something like MotorTrend or Road n Track that when Corvette and Camaros where running with the same engine platforms, the reason why the Corvette made more HP was purely because of the exhaust set up!?!? So if I read that wrong or misunderstood could someone set me straight on exactly how that applies or doesn't, I'd seriously appreciate it!
