out of the stock system you should pull 14 psi on premium and 9-10 on regular. with the stock t3, im not overly sure. i think around 22 psi or so, but someone else will chime in with a closer estimate. any pics??

Just say NO to Imports!
Most people tend to agree that the T3 is pretty much done by 18-20psi. His will probably be towards the 18psisince the 84's have the smaller exhaust side.

With a good front mount or alky the t-3 seem to continue making power in the 23-24psi range. The ihi seems to be about done at 20-21psi.
Keep in mind the psi is just a restriction in flow and 22psi on my car might not be 22psi on yours. That being said if you go test you will find what your turbo likes but it should be north of 20psi pretty easy.
Get a boost controller, you can use that to turn up the boost. As for not hurting the wallet, it depends on how much you will want to spend. Turn up the boost to ~18psi, bump up the timing a bit, CAI, these are cheap to do. Past that, it's pretty much about what you want to spend. A 3 in downpipe and exhaust is the best bang for the buck mod you can do. Anything that increases the airflow the car will see will increase the power. Porting anything/everything, swap to an E6, larger throttle body, front mount intercooler. Another small improvement that some do is swap in an LA3 from an 87-88 Turbo Coupe and installing the larger 35# injectors, some add the TC intercooler as it is a bit larger. If at all possible get a boost controller, turn the boost up to ~18psi, advance the timing a couple degrees, disconnect the knock sensor, K&N, and the exhaust work.

ok thanks alot but one more quick question 18 pounds of boost will my stock t3 produce that much and will my 23 year old stock motor hold 18 pounds. and is that on regular or premium gas
The T3 will do that easily. I run 12* timing and 20psi with a TC intercooler on 93 octane gas. A word of caution though, first, be sure the car is in good running order first before you start changing things. Second, don't disconnect the knock sensor before you are sure the car isn't knocking really bad. Some cars seem to handle more boost and timing better than others. 18 psi is a safe starting point, it will definitely go higher than that if you want it to. Basically what you have to worry about is a head gasket or something, the bottom end on these engines are very nearly bullet proof.
