I'm in the same boat. I'd say, start with Intake and exhaust (I don't know which is better first, but I went intake). Then, it's on to the internals (cams, electronics, etc.).

I'm in the process of beefing up my suspension, then I'll get to the exhaust. I like the corners more than the sound for now.

$6K will get you a REALLY good turbo kit with an awesome ECU to manage fuel/spark/boost so you don't blow your engine up.

Shiv Pathak sells one with a TEC-2, and Rally Knight is set to release another using either a Haltech E6K or Motec M4.

These are the only two preconfigured kits that I'd consider, seeing that most others either custom fit the system to the car, or use a combination of gadgets like S-AFC, ITC, voltage clamps, etcetera instead of an ECU.

With Shiv's or Rally Knight's kits, you're looking at 300+ reliable horsepower and torque without requiring any internal engine work. You may have problems with breaking gears in your transmission, depending on how hard you shift gears. If you can shift smoothly and don't drag launch it, you can get the stock gearbox to last quite a while. If you bang through the gears, and drop the clutch at 6200 RPM, you'll probably kill the trans in short order.

Whaddya wanna know? The kit was originally developed by Leading Edge Performance in Temecula, CA, for application in turbo EJ25 sand rails.

Rally Knight has worked with LE to adapt it to their rally cars, and have submitted samples to a testing lab in Arizona that is sanctioned by CARB to test to their standards.

Being in MA, I think you needn't worry about CARB legality, arguably one of, if not the strictest standard to meet.

The kit I'm getting is the first run of their 300HP street kit. It uses a watercooled T4 hybrid (T3/T4, I believe, but don't quote me), custom fabbed IC, Motec M4, and custom up/down pipe, cat back pipe, etcetera. All sensors needed to run boost are included, like a GM 3bar MAP, baro sensor to allow compensation for atmospheric changes, etc, but reuses stock sensors as well. (cam and crank sensor for sure, will get complete tally of what's stock vs what's replaced when my car gets back to me).

I won't lie, my price is cheaper than what you'd pay, because I'm the guineau pig. I'm Rally Knight's first commercial customer, and up until now, their supplier has only built for their rally cars. So they're going to take extra care and time to build mine up, and make jigs for future street kits.

thank u all, indeed a turbo kit will do the job for me, however first I'll probably motivate for a new intake and exhaust. However, i'm really concerned about my take-off acceleration etc.
and I've heard that with the exhaust you lose some power at take off and that it kicks in at higher speeds, it this true? or are there exhausts that can help my take off performance?

Most will argue that a 2.25" catback will have minimal low-end loss. A 2.5" catback will allow your engine to breath better up top, but it will come at a loss of the low-end.

Decide whether you will stay NA or go turbo. Things will be different for each route. For example, if you are going the turbo route, a 2.5-3" exhaust is going to be the best choice. (I say go 3") If you stay NA, a 2.25" will work well.
