Ok here's how it works, i have about 1500 to spend to make my tpi better stronger faster, however, i really dont know what to get, i really dont know much about engines, so this will be a learning expierence for me, im trying to get to know engines better, so what should i get that will give me the most for the money ? I have already done hi flow cats, and everything back from that. I also have the simple stuff such as K&N's and throttle body airfoil, and B&M shifter, what else to get ? Thanks for the help, you help me sleep at night !!!

 

WEll an good ignition set up will help. With the added airflow you might want to get an adjustable fuel pressure regulator and give yourself 1 or 2 more psi of fuel pressure. Some uppr intake porting is free and you can do it yourself. Some 1.6 ratio full roller rockers are very good to.
If you also want to handle better get you a strut tower brace and poly urethane bushing all around and some subfram connectors.
That should make you car feel a whole lot better and should run you aroun $1500 to have it all done by someone else, or if you do it all yourself that would leave some extra money to spen on say a set of headers or something, Now that I think of it HEaders are a real good Idea. Get those to.

89 Trans Am Turbo 3.8L All stock 43,000 miles #1053 of 1555

Past Thirdgen:
86 Trans Am w/ built 355TPI with SLP goodies and too much other stuff to List. One sweet *** car, wish I would have had a good enough Job to pay insurance on three cars so I could keep it, but for a 89 Turbo Trans Am w/ Low miles, I think I made the right choice!

 

Get these products:
Accel Super Ram MANIFOLD (most limitating part of TPI): 400
Spohn SubFrame Connectors : 200
Hotchkis stut tower brace : 175
SLP Headers : 375 (you can get them for 375 if you find the group purchase page on here somewhere)
High Flow CAT: $150
EDELBROCK Lifetime warranty Cat BACK: 300
Now your right around $1500

Assuming that you have the TPI 5 speed or 350, you have around 230 Horses,
Headers + Cat + CatBack = around 275 im guessing that is one bad *** exhaust
the Manifold will put you around 300.
Plus the car will handle this power with the subframes, and it will handle the road A LOT better with the strut bar,
HOPE THIS HELPS... right back on what you decide!

 

Also, If you look around at ebay, the classified, post parts wanted subjects, group purchases, etc, You could probably get all of it for around 1000. Then id spend 200 on a new hydraulic roller cam. and $150 Spohn Lower Control Arms and $150 on Spohns Panhard Bar to make the car with the newfound power hook up better and get better handling. Also, looked for people trying to get rid of these parts.... Ive seen the cam go for around 120 on ebay, and the panhard and LCA's for around 75 each, then with the 150 left after that Get your TPI Plenum and runners polished and ported. There is tech articles on how to do this to. Then youd have around 320 Horses with a good intake and exhaust, then youll have to modify what in between the two, the engine. Hope this helps to..

Buy your stuff used, there is plenty of used stuff around. Don't get the superram, it will eat up too much of your budget. Get some TPIS or SLP runners and buy an aftermarket base, or have yours fully ported. Get a MSD 6A or 6AL, do all the free mods listed in the tech section, and buy go-fast parts as you can find them.

 

1500 will go very far the only thing i would get that is costly is aa vigillante tourqe converter about 700 but you will definatly feel the difference than i'd look for exhaust pieces in the want ad the single most restrictive paart of aa tpi system is the crappy exhaust gm put on them go with a good set of headers y pipe and cat back hollow your cat out with aa screwdriver aand hammer and aan adj fuel pressure regulator to round it out on aa stock motor these mods will give you aa decent up grade no need to do intake work without cam and head work
