i have recently bought my first TPI IROC since i have never had one dont really know alot about the TPI motor i have had a few camaros and TA's current daily is a 98 TA LS1 but this is the first TPI so if any one can give me any ideas as of what to do to just wake it up it would be great by the way it is a 1986 with the 305

 

congrats on the purchase! i'm sure you will enjoy it.

im more into carbs myself but a better exhaust would be a good start for any car, they are all restrictive. A bigger throttle body, maybe some different injectors, a ram air or cold air intake, some better runners, an underdrive kit. then if you want to get into the motor, an lt4 hot cam will work wonders but i think it may require modifiying the heads. don't quote me on any of this, like I said, i usually mess with carbs and haven't really gotten into cams to much yet, do some research!

as always, i would recommend upgrading to a t-56 6 speed transmission and i would probably change the rear end gearing to like 3.73 or 3.42 or something around there. 4.10 or 4.11 if you want to get crazy.

 

thanks for the ideas ill check into a cold air and exshaust what would be a good setup dont wanna do flowmaster or borla have that on my TA and its just a over priced name

 

If it were me I would go with the magnaflow cat back, its around $430, but its stainless steel and is 3" so it has good flow. the best bang for the buck IMO. also i would get a high flow magmaflow cat, and hedman 68470 headers. They are pretty nice and they make a y pipe for them that can be modified for 3" after the y so its a very free flowing setup all the way through. it will run you around $6-700 for the whole setup not including shipping or installation which i don't think is that bad for a whole system and you can buy it in peices so that makes it a little easier on the wallet too.
I've heard as much as a 10-13% increase in power just from upgrading the exhaust.

 

 

gas leaf blower = 18 hp/tq

 

get some 3.23 gears or higher if you don't have them.

Also I'd recommend getting a good performance chip for it.
My Hypertech Chip really does help compared to how it drives with the stock 350 chip.
