Finally got the car, what upgrades first?

[Nick 91 RS]

I picked up a 91 RS 5spd a while back and just started catching up on the payments, so now its time for some upgrades. I was thinking intake, wires, cheap stuff like that. Any tips or suggestions? It's stock other than a cat back with the rectangle exhaust tips, dunno what kind, but it pops like backfires really bad. Also doesn't sound that good imo. what to do first? and whats with the popping backfire? is that the exhaust or is the motor out of tune or wha?

Headers, delete cat if you have no emissions tests otherwise get a high-flow, a nice 3" mandrel bent catback (4th gen LT1 catbacks can bolt right up to your third gen, it's the same setup)... what's the induction on your car? Get some type of cold air intake or if it's TBI or carb i guess oen of them high flow air cleaners... if you wanna spend a little more, a limited slip diffeential with 3.42 or 3.73 (or 4.10 if you're feelign ballsy ) gears would be nice

97 pretty hit all the basics, it not done already, give it a full tune up. Some good sythetic oil, delco plugs, oil filter, fuel filter (will make difference if it's never been changed, wires. Edelbrock Tes headers are a good choice for 3rd gens. The magnaflow from and LT1 powered f-body, would be catback of choice, provides really good flow and sounds damn good too. I have the american thunder catback (flowmaster), sounds really good, didn't really see much of a difference as far as performance goes. Awesome, you got a five speed, i was looking for a five speed LB9, but didn't have any luck.

I'd do a complete tune-up if the car has somewhere around 80K miles or more.

Yeah I hope for his sake it isnt a 3.1

[Savage Messiah]

I wouldn't put synthetic in unless it already has it.

[Nick 91 RS]

sorry, its got the 305 TBI. theres around 110k on it, and already has posi. I changed the oil, oil filter and air filter myself probably 1,200 miles ago. So the backfire when the RPM's go down is from it being out of tune?

[Savage Messiah]

could be the muffler is shot, could be plugs/wires. Can't really tell online from your description

[drvngstorm05]

intake, exhaust, shift kit, holley 650cfm tbi unit... alluminum driveshaft... deeper gears... and a chip. those and the things other people listed... relatively easy mods that will help wake up the car... congrats on the car man

Well you should still replace.. wires, spark plugs, fuel filter, rotor and cap, and if you want to be safe, your fuel distributor. The backfire could be from the muffler though.

a fuel distributor? there's no such thing...

[Rally Sport]

Yeah.. its the thing that is right under your cap and rotor, and under the ICM. All the way in the back.
