1. CAI
2. Cutout / Cat - Back
3. 1.7 RR's / Springs
4. MadWolf Tune.

I did the CAI a few years ago, it made a nice diffence, then after a day or two later, the difference wasnt as noticable. I would think that the CAI leaned out the overly rich LT1 mixture and the compuer after a bit learned and compansated again making it rich. I think a tune would help.

 

Stay away from N20, first of all as mentioned, IF something goes wrong then you will be without a ride. And don't forget that best bang for the buck is prolly headers or CAI, because with N20 you have to refill the bottle ofter and that can be costly. a full bottle will prolly get you about 8 passes then you have to refill again. Not very cost effective.

 

The 94z28 that I just sold had all the bolt ons and lt4 hot cam and such. Here is my opinion on order of worthiness.

1. Get a cai (without it other bolt-ons are crap)
2. Catback
3. Torque converter if auto(2500 slp stall made more car easier to drive and gave it more manners. )
3. gears tie with tc
4. headers
5. cut-out
6. Cam and rockers


With just 1 and 2 my 94z hard top ran a 13.7 @ 102
with entire list I ran a 13.1 @ 109 (couldn't hook up with nitto dr's)

Now i have a 94z28 vert and have to start all over. In the spring when the car comes out again I have a slp cai, loudmouth, and 3.42's waiting to go in.

good luck

I wouldn't advise 1.7 rr's unless he plans on staying with his stock cam or a very small aftermarket cam...you gotta watch for clearance issues with the lift...
