FAQ: Series I Performance Mods?

I have a series I Riviera with a CAI and 95,000 miles. I'd like to mod it some more and was hoping to get some help with what to do to it. A series II swap is out of the question. I have $500 to put into it. Any help is appreciated!

a FWI a 2.6 pulley auto light 104s and a custom cat back

Can't do a FWI, I'm not cutting the car to make it fit.

then just do a regular short ram intake

I think most of the guys didn't have to do any cutting. I did on mine because I didn't want to have to go through the fender well everytime I needed to clean the filter. But even though I cut mine, the factory box will cover any enlargment to the opening I made if i decide to put it back stock.

I have a CAI as it is. Could you explain a custom cat back? Also what about a KR scanner, do they have PCMs? thanks.

If I had only $500 to spend on a series I, I'd do a CAI/FWI, scanner, mini AFC, AL104s, 180 t-stat, & 2.6" SC pulley... Make 15-20 HP and call it a day!

custom catback would probably be eliminating the resonator put in a 3" pipe into a Y pipe with 2.5" exits to two hi flo mufflers... just an exhuast system...my guess is it would cost about 250 at most muffler shops.

Any sites to suggest ordering from?

exhaust is up to you, go to you local auto parts store get autolight 104 IN COPPER shouldnt cost you more the 7 bucks for the plugs

EDIT, get a 180 t stat from your local store i got mine at advanced auto parts for 10.95 its a stant 180 thermostat

you could go find a CAI that fits on another car but has the same bends that you would need. i think mine fits a acura or honda, cant really remember, bought it new and cheap off ebay.

what is FWI?

FWI = fender well intake... the pipe routes into a conical filter in the fender well.... theres a bulletin with all the abbreviations somewhere... mps is modular pulley systed , dp is downpipe , pcm is powertrain control module.... those are some of the common ones.

Does anybody make headers for the series I?

Don't know, but this place may: www.seriesoneperformance.com

Also I need some ideas for what to do with my series I. I don't realy want to swap it for a series II. I never had a blown engine before. Is it safe to run it on nitrous? If so how big of a shot is too big for these 6 cyl.?

naw they don't even have an exhaust dept.

I have heard a guy run a 100 wet shot. I would make sure your fuel system is up to spec first.

call me crazy but the GN headers look the same. i know the GN is RWD. but im sure an exhaust shop could make it work

hey everyone, my name is justin and i own a '95 riv. i wanted to put a smaller SC pulley and a cold air intake on it. Any suggestions on what size and make? i want to go as small as i can without having to do a lot of other mods

Can you put headers from a series ii on a series i and what other go fast bolt ons can you put on a 95 riv that will helpall i have is a CAI and straight pipes

fraid the series one is a bit scarce in the mod dept. Headers won't work from a series 2, because on the series 2 the exaust ports are evenly spaced. The series one has un-evenly spaced ports, so if you wanted headers on the series one, you really would have to get them custom done. For mods, start with the basics(tune-up etc), then move to cooler Tstat, and scan for engine knock. If you are knock free you can drop a pulley size. also you can consiter doing a port and polish on your lower intake manifold.

http://www.pontiacbonnevilleclub.com/forum/ has a bunch of good info on series 1 modding

mmk then well i just had the whole motor redun jet washed with new rings and pistons and the crank was balanced so the motor has no knocks also what are some good handaling mods that can be done to a riv to reduce body roll and stuff like that
