It costs me around $2500 to make the kit, but that's with the intercooler and piping along with the downpipe/midpipe outsourced to a overseas factory. When you get stuff mass produced, the price comes down significantly. If you were to build everything yourself and source it all yourself, you would be looking at around $3000 in parts or so. Then you would have to do all the wiring, tuning the FIC, and fabrication yourself.

Please add me to your list. I'm starting to reread maximum boost and starting my initial research. I've got a 2002 sportsdesign as well, and low boost seems to be the initial goal. And ultimately I'll do a tranny swap once I open up the head. What suspension upgrades to you suggest with this added power?

glad to see a fellow NA-T on here. i just got done doing my 2nd overhaul on mine with swapping all TT internals and a .70 trim. Are you running a valve body upgrade on the trans and if so which one. I know you were talking about making a kit for these car but your still working out the kinks.... if you need a hand i can help. My first setup i was running only 18psi but ended up cracking the pistons and now everything is setup for 900+ HP

Here is the parts list. There might be some changes made to the kit. As it sits right now, the Stage 1 is limited to 5psi because of the stock injectors. You can actually run around 8psi on stock compression if you have large enough injectors. I'm trying to keep the Stage I kit right at $4k.

Actually, I am running with the stock exhaust. The down pipe and mid pipe will work with either the stock or aftermarket cat back exhausts. Not much loss of power since its only at low boost. I like keeping the car quiet so I kept the stock mufflers. You can't even tell the car us modified until the turbo spools.

I would say that if you raced a gs4, the gs3 with this turbo kit will beat it after 60 mph. Maybe not as fast off the line, but when the turbo kicks in it definitely has more kick than a gs4. Keep in mind that's just the stage 1 kit at 5 psi. If you bump up the stage 1 to 8 psi, then it will eat the gs4 alive lol.

Man im kinda wishing i went with a GS300 instead of a gs4. Im pretty much maxed out with whats possible for my car and i want MORE power

Yea, that's the problem with the GS4. There's not so much aftermarket support. The GS3 at stock compression gains around 20rwhp with each psi of boost. At 5psi, the car puts down approx 280whp. 8psi will net you around 340whp. Stock power is about 185whp.
