99-mod AT200, turbocharging with stock tranny/clutch++ Options

[Illyont]

My question is. If I turbocharge my standard engine, will I need a new transmission/clutch, brakes etc?

Or to put it this way, how many horsepower/psi of boost can my standard transmission/clutch/brakes etc. handle before something blows?

I'm not interested in a GT-4 or all out engine swap and 300+ horsepower. I just want to freshen up my 116 hp standard engine a bit. Anything above 150 wheel horsepower and I'm happy. New intake, header, exhaust and a turbo should be able to get me those extra 35-40 hp, right?

Also, the part search lists the Greddy SP1 Cat-back exhaust as a possible addon to my car, but is that because in US the 99-model Celicas are all 2.0 litre GTs? Or will this exhaust infact fit my car (non-GT european). On a sidenote, why should exhaust for the GT not fit the non-GT? The cars look the same, don't they?

(This is the German version of the car with a 1.8 litre engine (1.8i), not the 2.0 litre)

You should be able to hit 150whp with those mods, yes. You could probably do it on stock tranny etc but I doubt that it is recommended. The SP1 is no longer in production and no one can say for sure whether or not there is a Greddy SP2 for our cars. The AT200 is a US model as well with the 1.8L 7afe engine.

Okey, thanks for your help!

[97sccelica]

it can take 150whp easily if its in good shape and you know how to drive

the clutch on the other hand, i would plan on changing that soon.

brakes, depends on how quickly you plan on slowing down, just because the car accelerates faster, doesnt mean that it will brake slower, get fresh rotors and nice pads and new fluid. you should be fine, you might even consider a rear disc conversion if you are still worried about it.

My car have 50 000 miles on it. So everything should be in good condition. Atleast yet. And, I'm pretty sure my car already have disc brakes in front AND in the back.

They didn't put rear discs on any ST's did they?

Good deal man. You got to love them 4 wheel discs. I learn something new every day. This sites good for that.

I'm still looking for an answer to this. If anyone know about it.

if you have 1.8L 7afe i've got the prefect thing for you a turbo kit
at only 9.5 psi you can have 170whp and 180trq
check the FS forum and its on ebay under 7afe turbo kit
there are dyno sheets and videos on here also if you have any questions e-mail or Pm me

[94ST2]

Nik didnt you boost over 10 psi on your stock internals

[Blakout16]

yes he did boost it alot higher than that but found it actually hindered the hp because of poor injectors i believe... he's in the process of building a 7agte if i remember right.... really hott setup

[Blakout16]
