Celica Forums General Discussion Exterior Automatic Celica GT Looking for Horse Power!

I have a GT and I need some speed. It is slow off the jump of course, but I need some advice on what to get. I need exhaust, but everyone in town says they can't bolt any muffler on the brackets and I would have to get a whole new cat-back or the trd sport. If anyone has some advice please help!!!!

Intake, exhaust, headers...but to tell ya the truth man its not gonna do much on the auto

sell it and buy something faster.

GT auto can't and never will be fast, unless you dump A LOT of money into it.

Hence, buy a faster car.

don't feel bad dude i got an auto. one mod i found that worked well with throttle response was the AEM pulley. of course just the pulley alone won't do much and you would have to invest on i/h/e. but if you want "uber"-speed then you will have to look at forced induction (or/i.e. turbo/N2O/s/c). from experience bolt ons do not add as much to an auto as it would a manual but they do help and my car really is a lot more peppy especially in mid-high end

Do you know any website or place I can get the AEM pulley for a good reasonable price? I heard the K&N FIPK system was good, but I haven't heard anybody say anything about AEM. Which would be better?

AEM isn't going to give you a noticable increase in power because it only under drives your alternator. If you want a good HP gain from a pully, you should get a crank pully that slows all accessories down.

I would reccomend looking into the UR crank pully (unorthodox racing).

the store here in e-celica

... great service!!

Natnan...do some reasearch before you purchase crank pulleys like UR. there have been a few cases where there have been engine troubles due to this mod (look then up at new celica.org or search thourgh mod section at ecelica.com). the AEM pulley is safe because it does not require removing the harmonic balancer...yes UR will give you more power but there is a reason why i didn't get it. you can try it out, many people have it and they experience no problems buti don't feel like playing russian roulletle with my car.

one word for GT performance... Supercharger!

TRD is putting the kit together as we speak, the lower compression of the 1zz will allow for ample boost levels.

yu,yup...and i've seen what a 1zz s/c trd can do

...it's sweet!

Yeah a supercharger would be nice, but I don't have 3 grand off hand!!! They are expensive and a lot of people I talk to say they don't make that much of a difference. I wish I had a standard transmission to mess with. I should of just gotten the gts. I don't know anything about the pulley's, but I can research them. Would throttle body help me at all of the line?

And Natnan Get a Honda S2000 Antenna, That Adds 20 HP...J/k, but yea it looks way better than that Lighting rod you have there.

like i said before just add stickers...

all you need is STICKERS!

Just make it a show car

actually I know of someone that did all of that to their celi and it actually made it slower at the track...Before the header they were running atleast 17.xxx and after 19.xxx

wow...that sux. that must have been at least 900 bucks worth of mods...

hm...as all you guys say..GT is slow..but what about gts, it's only got 180hp, what can you do about 180hp, i just don't understand you guy's. gt is still a celica, even gts, when you put a S/C or even a turbo, its only have 280-290, never can go over 400+ so i think celica is all about the look. and racing, it's all about the driver. i just hope pple here dun fukin look down gt. that all i have to say, Celica=Celica, no matter what, we will all owned by those new car like 350Z,Supra, NSX, you never can beat'em so... and i going to get a supra, and i got a Celica GT auto now, and i think i will still keep the GT auto, cause i love celica so much. Peace

well we are just tryin to get enuff power to at least beat/keep up with the tegs,civics, and other compacts we see on the road out there. of course it wont beat 350zs, NSXs, Supra and such.

Yay I agree!!!

Does the Mustang V8 = the Mustang V6? Or does the RSX = the RSX Type S? The difference is a matter of seconds in the 1/4. That's car lenghths, and quite a few. And by the way, the last production year for the Supra was in 98 I believe. So I don't think it would be considered a "new car." A fast car...YES. And I have to call bullshit on the fact that you would take a Celica GT auto over a Supra, unless you are clinically insane or a soccer mom.

But anyways, I'd stick with the simple mods such as Intake, Exhaust, and Pullies, etc. I wouldn't waste your money on headers.

Simply put, if you want BIG hp and tq and have an auto GT, you bought the wrong car.

OK everyone has made their point about automatics. If you aren't ready to bag it yet, you want to try to go for mods that don't hurt the low end power you need to get that auto moving. I would suggest pulley's (just the aem alternator one or the full UR set if your brave) a K&N filter, groundwires (some say these help throttle response and low end, some just get brighter lights, but good either way right?),and the lightest wheels you can afford, for a start. None of these give you the high peak hp numbers, but they will help, they won't hurt low end power, and all (except wheels) are pretty cheap. Good luck!
(edit) btw I have a 5sp celica, my auto experience is with other cars so take my opinion for what it's worth!

Which one of these mods would do this? Im not looking for power gains cause im goin to build a show car. I wanna add intake and exhaust maybe headers just for show purposes but not if im goin to lose power. So do you think it was the headers that probably did this? or what?

Yeah it was after the hotshot header was added. Apparently, the person went back to the shop who installed it and they looked it over again and said everything was fine. They didn't notice a loss of hp during daily driving, it was only when they took it to the track. I heard that it has something to do with "too much back pressure." But this is just what I heard, I don't know anything about "back pressure, etc"

So i should be fine as long i stay away from headers? and just get exhaust and intake

Well, I would ask other auto celi owners that also have headers what they think about it. Don't base everything on this one car, I just wanted to give you a heads up.

wow...just when i was thinking of headers..lol. thanks celiprincess! i'll do some research on this...

If you find anything please post it or PM me

huh.. headers free up air flow and relieve back pressure. most likely with you have I/E/H you will have lower back pressure and lose low end torque but gain high end.

that is wgat i am thinking as well. lose low end but gain in the mid/hi end..i felt this when i got my i/e...my pick up a bit slugish but after 3.5K it pulled great...

like I said...I don't know exactly what happened I only heard it had something to do with "back pressure" Now thinking back it could have been either no back pressure of too much...sorry, it happened a while ago. But im not an expert on this stuff...I just wanted to let people know what happened to this person. I didn't know if it was a common problem or not. Im just trying to help

There are turbos available for the the GT. Auto or stick, it doesn't matter, additional HP's are additonal HP's. Don't worry about it being an auto. If you don't want to pay for the turbo, then a CAI and exhaust would give you a nice gain. I have heard several people with Hotshot headers that are having problems.

I heart GT Autos/Manual have most turbos like the dude said above, if you dont care about asthetics save up and buy a turbo...patience is a virtue..regardless what people say, auto is slow no doubt but you add a turbo pushing 7-xx psi ur gonna nottice a differnce, a lot to gain, and do some suspension mods after that, you have a decently fast car, that corners great... fun to drive in my opnion... i like standard too but sometimes its not practical in busy downtown areas, or just plain stop and go driving... my .02 cents...

personally i like the auto if ya are gonna turbo it, a lot easier to put in a tranny cooler than to replace the clutch all the time
