just so i know, its the ECU that robs the USDM version of 31 HP?? Thats nuts, you can only optimize a car so much for 103 octane (thats regular in japan) and it wouldnt have that great of an affect, EGR valve does some of that by creating more back pressure than the JDM version sans EGR, but its only by a couple of psi, which shouldnt have a big effect, no more than 3-4 top end HP, but 31 no way, again the best thing i can think of would be increase the boost to stock JDM levels (10 psi, is it?) and that should have it back to proper 231 HP spec, if anybody has anymore info please post
thanks for the posts, i just wanted your opinions on the subject, cuz the 2nd gen 3SGTE is fairly cheap if bought domestically and i wanted to clear up the issue of the missing HP, 30 is alot when u think about it people, and if it can be had with stock boost levels then all the better, plus by not having to import the engine i save a ****e load of money, money that will one day (a year or two from now) be used for an AWD conversion, Muahahahahahahahaa

The emission rules in japan are different than the ones here, but the cars over there have less actual emissions and run cleaner, people who import cars to North America cant pass "visual emissions" which is part of e-testing, so thats what the big deal is...even if USDM engines had insanely draconian (haha, i feel smart) emissions controls, that still wouldnt drop the power of an enigine by That much, the only thing that i could see being emission control related would be if it had something to do with the ECU cuz i have no idea what OBD system JDM cars use vs. USDM ones (either OBD I or OBD II)
haha, thanks for the help though, got me thinking some more about it.
So if anybody knows why the engines are rated differently please post, my best guess is something to do with the turbo/turbo settings.

but the engines are from the same generation (2nd gen 3SGTE) so it should be the same engine.......DAMN north american polution laws, JDM cars run cleaner than USDM cars, the only problem up here is visible emissions (north america is way too strict with that), the US version of a JDM car would never pass japanese emissions testing (this is a fact), and i refuse to believe that emission controls rob the engine of 20/30 horses. ARGH, haha this is frustrating
thanks for the reply

Ive been researching the topic and have yet to come across a reason for the difference in the ST185 ratings, the USDM engine only pulls 200 HP and 200 lb/ft of torque, while the JDM versions of the same engine make between 221 and 231, im almost positive that the engines themselves are identical, same bore, stroke, CR...etc, so where does this mysterious power lie hidden. Could it just be the difference in the stock boost setting, are the turbos the same, what gives?
I'd like to get myself one of these babies, and im wondering if i get the USDM version if it would be an easy matter of freeing up the 21-31 HP in there,
this is only regarding the ST185 3SGTE, and not any other generation of the engine
Also if anybody knows any place that would sell the USDM engines here in Ontario (maybe even Quebec), cuz id much rather not end up having to buy the whole car (im on a freakin' buget, university starts in the fall)

hey speedracer_2020, im from ottawa and i was down there for the CART weekend, props on the car, were the sportlines easy to install cuz the car looks awseome,and i dont have the cash for coilovers yet.
would you know of any decent engine importers in T dot because im really looking at maybe getting a swap done,

Ok guys...
look at it this way the 360 modena (I LOVE that car) is a 3.6 L V8 with 400 HP
and the 3sgte is a 2.0 L i4 with 250-255 HP, now the ferrari is only only 300 pounds heavier than the 6g but if ur going to mod the car u can get a 6gen under 2200 lb.
GT2GT4 - man just reading those parts made me drool...imagine all that under the hood of ur average 6g celi gt haha. Oh yeah and the Modena costs $152,000 USD, and what GT2GT4 is suggesting would cost about $55 000 including the car and u could still spend about 5 grand on details like suspension and gearing. so with about 60 grand u could have an 800 HP (yes 800, with the parts listed and with mild tuning u should have no trouble achieving that, Port everything u can and this turns into 800 HP at the wheels) AWD Beast that could take on most ne car. if u really want to go and race a ferrari like a week from now get a 3sgte get the biggest turbo u can, strip the interior and get the biggest nitrous shot u can (I personaly dislike that method, like the man said its ricey) and u should be able to keep up with it.
Ferraris are sweet but you gotta respect our celi. given enough money ne thing is possible however and you could make ne car that fast. But few would have the looks that that rival the top exotics like ferraris. by the way an 800 whp celi that weighs around 2200 lb would run mid to low 8's and the 360 modena runs 12.8 on the quarter. Plus ur car would handle almost as well so u could win no matter what the race.

Dude save up another 5 grand and get an Rx-8 fully loaded... then turbo it. with a custom turbo setup/intercoolers on the renesis engine u could be pushing almost 360 WHP with medium boost, thus raping anything short of european exotics. Period.

is it possible to put one of the 4A engines into a GT fairly cheaply (compared to the 3SGTE)?

And can some one give a straight answer, which is better the 4AGE balck top (165 HP) or the Late model 4AGZE with the 170 HP, since the 4AGE isnt supercharged, and has the unique 20 Valves and 4 throttle bodies/cylinder it should have more potential right? If I were to get the 4AGE, could I just supercharge it in the same way the 4AGZE is done (I know that the GE has a CR of like 10.3 and the GZE has a CR of 8.0 or something, but even running a tiny supercharger on the GE would yield more HP than the GZE has)
I'm really considering this as a swap, since I would love to see what I could do with the small 1.6 L and all those intakes when it comes time for tuning.

How come toyota built such a great small engine and then gave us cars that are pretty much all show and no go. I think the engine should reflect the appearence of the car, if it looks good make it fast.

Are u guys nuts?
The RSX TYPE-S way made to work with its 200hp engine.
its tuned
and it runs 14.8s stock.
2001 RSX Type-S specs
now a GSR would run slower then a Type R
which also runs 14.8s.
The RSX is hailed as the fastest production FF car, the celica and the GSR are not.
now a turbo celica with those mods MIGHT win, as the competition is pretty close and anything COULD happen, but ill bet on the GSR coming 1st the RSX 2nd and the celica 3rd.

V8's sure,
Sweet, strong solid engines with massive power.
Just keep the US made SH$T away from me.
Most US V8's make about 50 Hp/litre of displacement very unefficient, they also fall apart.
If ur gonna get a big V8 or 10 or 12 get it from europe, 4 bangger/ 6? get it from Japan.
Japan - compact economy cars Very efficient sleepers decent engines make 100 and up HP/Litre (7g GTS, S2000, 2JZ, GSR, etc.)
Europe - Finely tuned, elegant machines making at least 100 HP/L on average (all Porches, ferraris, Mid-High end BMW, etc.)
American - Utter **** that falls apart in no time flat, cars made with junk parts and driven by morons. Oh yeah theyre f$%king slow and make about 50 Hp/L.
Note to V8 drivers: Dont get in my face and brag about the 300/400 Hp u got cuz
1. with the money I save buying an i 4, I'll top that.
2. Ur car's made from old toasters, and if u try and race me in curves it'll fall apart
3. I know cars enough not to buy Domestics (Ford's, etc.) so while you rant about big muscle cars, I'm laughing at your redneck accent.
4. Any one can squash a gas pedal, but it takes a refined taste to appreciate the engineering of a smaller engine
5. My car weighs a ton (literally) less than yours.
6. Jap/Euro cars look 10^99 times better than US V8's.

I found sweet rims, not too expensive, and they look sweet, check them out:
New Rims
whaddya think?

Big Pic

What Body Kit is that, it looks better than pretty much anything i ve seen so far ?

Not to bash the whole 5sfe idea but the costs are pretty close (plus or minus 1000 right), and you would get a world class racing engine if you went with the 3sgte.
The engines are different past the point that one is a 2.2 L and the other a 2.0 L.
The 3s has internals that rival the Nissan Skyline R34's engine in strength and capacity for horsepower. Also if u go with the 3s and get the 225/255 Hp, and if thats not enough yet (it not enough... its NEVER ENOUGH heh heh heh...) you could always get a nice new boost controller and double the boost there by achieving the HP of the average Supra TT. While on the other hand your 5s would top out somwhere around 300 Hp and blow up a week or so after that. I love the Celica in all its forms but given the choice (by which I mean if I had the cash) I would trade in the 5s for the 3s. But whatever you decide It should be your choice, If you only want an engine with a little more go for every day driving spend a little on a small turbo or mabye get one of the 4A engines (like that exotic 20 valve), but when it come to substituting a turbo 5sfe for a 3sgte its just not worth it

HEY Toyota, How come the celica has such a wimmpy engine. Please give us 200+ for the 7th gen.

Where those prices US or CAN (US price/0.68)

First of all I have done an engine swap before (B18C1 Integra GSR into a Civic DX ps:civics suck), granted it was pretty straight forward that engine and the car are almost interchangeable. Second my friends father is a mechanic, and their garage has a pit in which i have worked in. That same friend has an amazing Mitsubishi eclipse turbo for which we did a turbo replacement together. And since I have never done a drive conversion I had to ask if it was hard or not. Sure Im no mechanic (Going into Biology/Life sciences in the fall) but I'm pretty sure I can get away with having to pay little/none for the labour on the AWD conversion.

Thanks for the numbers though.

If I get the ST205 Clip and get that dealt with (- read - Thats a big IF (I'm in my last year of high school and have all my cash going towards university, scolarships are pending)) HOw much would it cost to do the AWD conversion. would this be something I could do on my own? Is it harder or easier than an engine swap (with a clip). This conversion is pretty much a must, if I decide to get the 3sGTE, that many horsies in a FF car (front engine, front wheel drive) would really take away from the experience/clean starts off the line. Also I have a bunch of mods already (UD pulleys, sway bars, short shifter) would any of these have to be replaced or would they work with the new engine and drive train?

PS: anybody know how easy/hard it would be to get a 3sgte in Canada (Ottawa).

Has ne one done this yet?
What I mean is, has any one gotten into the OBD II diagnostic interface of the post '96 celicas. The OBD II gives all kinds of info about the way your car is running but it costs like $200 dollars to buy the adapter/cable/protocol adapter. That money could be used elsewhere. So has any one done this without buying all the stuff needed?

does the DR. CAI work on the GT/GTS ?
