As I always say, the first "mod" you should do to your 2.8/3.1 (or even V8 for that matter) is to give it a major tuneup.... which isn't just the usual "plugs/wires/air filter" that a garage charges $100 for. When your engine's at it's best "stock" running condition, you'll see the most gains from any aftermarket parts (like exhaust). For instance, why put a hotter spark coil on the car when the distributor cap is the original from 1988?

Tom P's Major Tuneup Info: 3rd gen (82-92) F-body series

Here's the Major Tuneup stuff- this covers alot more than a garage would do for you, and it'll wind up to be cheaper (or at least the same price)! First, buy a Haynes 82-92 Firebird (or 82-92 Camaro) manual.. they're about $15 from any auto parts store. I like them alot better than the Chilton's manuals (which aren't what they used to be 25 years ago). And of course, the ultimate manual is the GM Service Manual, available from http://www.helminc.com - I paid about $60 for mine back in 1994.

Replace: Distributor cap/rotor, spark plug wires (use aftermarket), spark plugs, air filter (use K&N replacements), PCV valve, fuel filter, engine oil/filter, auto trans fluid/filter (or manual trans gear lube), and rear axle gear lube (use limited slip additive if required). Check and reset the timing to stock specs (in Haynes manual). Check and reset the TV cable if you have an automagic (in Haynes manual). Do a lube job and get an alignment done- the car will go faster "easier" if the front wheels are straight. Buy a can of "Intake and Throttle Body Cleaner for Fuel Injected Engines" by Gumout (yellow or gray can, with a red cap), and follow the can's instructions to clean out your intake. DO NOT USE CARB/CHOKE CLEANER- this removes the protective coating fuel injected engines have. Put a bottle of injector cleaner or my "red magic" (STP Gas Treatment) into a full tank of good gas.

It's also a good idea to replace your coolant, check your brake fluid level and p/s fluid level, check the belts, and check your brakes while you're at it.

Call Summit Racing at 800-230-3030 for a free catalog, then you can pick and choose a spark plug wire set and get your K&N air filter(s). (You can also find this stuff through their website, at http://www.summitracing.com , but it's not as thorough as the catalog.) When you leaf thru the catalog, you WON'T SEE any parts listed for a 2.8l v6 - you need to call them and ask them for part #'s/availablility. (Same goes with exhaust, etc.) If you're like me, and can't want to wait for the catalog in the mail, call them and order one anyway! Then, go to their website, at http://www.summitracing.com , look up their ignition wires, decide on a brand, and give them a call for a part # and price.

But definately do a tuneup first... you'll see the best improvment from the "fun" parts when your car is in good running condition.
