16-18psi will yield around 350whp. Do you really want or need that much for a FWD? How deep is your wallet? I don't know if your dealer is knowledgable about custom turbos and aftermakert parts, most of them are ignorant when it comes to that.

For the boost you are asking for you need (in addition to a intercooled turbo kit):

1. 8:1 or so compression Forged Pistons.
2. Forge Rods.
3. Possibly resleeve block.
4. Fuel sytem upgrade (Return fuel line, bigger pump, injectors, etc).
5. Full engine management system like Motec, Tec 3, SplitSec, etc. and tuning.
6. Upgrade MAF sensor (possibly one from a Mustang or Ford Lightning)

16-18psi on a GTS? Goodluck.

What turbo do you plan on using?

yea, that will be highly unsafe unless you build the hell out of that motor and i'd just take a guess of you spending at least $10k + on that. plus, IMO that's just too much power for a little light FWD car. my friend's put down 230 to the wheels which felt crazy and barely gets traction as it is. good luck though, but i'd highly reccomend lowering your expected power a good bit and doing a TON of reasearch, turbo'ing the GTS isn't an easy task.

Uhhh, maybe you yourself hasn't put enough research into it? Can I say compression ratio? 16-18 psi on our compression will blow the oil pan off the block! not really, but u know what I mean...of course, with the right amount of $$, anything is possible.
look at one nyoneway posted..he's completely on the right track...LSD would be a good idea also to get the power onto the ground

Y is it made to seem like it?

If your asking questions such as those above, then I'd say you're no where close being "in the process" of installing a turbo kit on your car.

Maybe this needs to be moved to the newbie forum? :)

celicarcr2026:

You should check out the thread on the XS Turbo, then seee why they only wanted to boost 7psi on a GT-S.

I am not saying it isn't possible. It just doesn't make sense for someone to spend that kind of money (roughly 12k-15k to parts, installation, and tuning) to a GT-S. If you do have that kind of money, it will be better spent to trade in your car for something else. :)

A lot of us know about many turbo projects for the GT-S and how difficult they've been, even at boost levels much lower than those you are talking about (we're talking 7 psi and less). I only know of two companies who've attempted boost levels even close to what you are asking about on a GT-S, and they only attempted this after MAJOR internal modifications to the engine. Call them to get some first-hand answers. The trick, however, is to talk to a real tech person over there instead of some phone salesman that knows very little about anything:

TRD USA did research on fully-built GT-S engines running lots of boost for Christian Rado's racecar, before those original plans were scrapped. Call and ask them your questions: (800)688-5912 .

EIP Tuning made a prototype GT-S turbo kit boosting around 12 psi with a built-up engine. Keep in mind, this kit cost 10 grand, WITHOUT installation or tuning.: ORDER LINE: 410.871.0406
TECH LINE: 410.876.1336.

going that high on boost you better have one hell of a engine rebuild. Not to mention the best stand alone management system. Just these two alone is well over $7,000. Add ball-bearing turbo and all the other goodies... I say well over $12,000.
Well if you are still going through with this I wish you luck, because you will need it.
