Celica Forums General Discussion General easy low cost engine mods for GT Celica what mods should i go fo

hey all im a noobie lol i geuss you all geussed, i have a silver celica

hey all im a noobie lol i geuss you all geussed, i have a silver celica GT(i think) its a 2005 model.
i am from australia, in australia they dont have celica gt/gts they have the equivelint model celica sx/zr i think SX=gt ZR=GTS i have an sx(GT i think)
and i plan to get the APR wide body kit, nice wheels to fit, but i dont know much about engines and such i was wondering what some simple low cost mods that i should buy to add hp to my stock celica while i save for a turbo. also i was wondering if the celica has alloy pistons? and wondering if the auto GT celicas over in other countrys have E-shift? where you shift with buttons the celica's in australia have this. i think its the equivalnt to the porche triptronic gears.

thx hope i get some replys.

I've heard trd stickers add about 20 hp. j/k. Imo, there's no such thing as a low cost mod to boost hp. A pully ($80) maybe the cheapest but thats only 1 hp. Intake or exhaust, in the $100 - $600 range would be your best bet for noticeable gains.

ok cool i just meant low cost as in under 1000-1500 dollar mark lol

my celica is australian based sx ohh i think its got the 2zz engine init and its 2005. i was wondering if they are LSD?, ohh and do they have alloy pistons?

Exaust, Intake, nitrous

lol sounds good i was wondering what kinda exaust i should get?

should i go for a 2.5 with a 3 1/2 tip or a 4" tip?
and would a cold air intake improve the performance of my car alot?
how much does this cost fitted?
and does it add hp?

CAI will give better gain when compared to SRI. AEM Version 2 CAI is pretty good, that or TPR intake if you can get a hold of one.

I would get a TRD Exhaust give your budget.

Intake + Exhaust

in simple terms? cia=? sri=? aem version 2 cia=? trd=?

i do assume they are brands?
would that be accurate?

Cai= Cold air intake
Sri- Short ram intake
trd and aem are brands lol

i would go for cold air intake witch brand is better trd or aem?

whats the diff between sri and cai?

Cold air ducts air from outside the engine bay
short air is a short pipe.
Look at the install section. and :google:

take your air filter out (JK)
Ground that engine!

put a sweet kit on it, but first i would have to say intake!!

ok cool and how much would it cost installed?

ohh go to the other one i added this twice and other one has more info sry

thx so trd is the go?

can you hook the cold air intake up to the stock bonet scoop for more intake?
or am i retarded?

can but won't be volumetrically efficient as a store bought duct/filter.

in simple terms?

ohh and by the way i found out that the australian SX is the same as your GTS
so i am the proud owner of a 2005 model GTS with sports shift (E-SHIFT)
lalalala yay !

No, not effectively.

Anyway, the TRD (Toyota Racing Development) exhaust is a good bet. Also, the TSRM (Tanabe Super Racing Medallion) is a good exhaust, but is louder and doesn't look stock (I think it looks better). If you are going to turbo soon, skip the cold air intake and exhaust, because the CAI will be incompatable with the turbo, and for the exhaust, you can get a custom exhaust made for your turbo set-up for about as much as an already made exhaust, and get more power while your at it. However, if it will be some time before turbo, then go ahead and get the intake and exhaust.

For pistons, check out Wiseco. Google that and looks for the site.

For LSD, C2 Power makes one, as does Quaife. I believe the Quaife is a clutch-based LSD, which doesn't make for a good daily driver (at least I don't think so). If you don't know the difference in differential types, search and read up a little. It's an easy way to make sure you get what you pay for for such a costly mod.

As far as your car, it has a 2ZZ VVTL-i engine? Just so you know, that's a GTS in the US.

ok thx i figured it was, so cold air intake has no point if i get a turbo and no point getting an exaust if i want a turbo. well damn turbo will be costly and if i buy the intake & exaust i take longer to get the turbo.
how much HP gained from a CAI?
how much gained from a turbo running 10-12PSI?

what price range would a turbo to fit a GTS cost i wanna run 10-12 PSI most likely looking at HKS if you know any other good brands let me know thx

A full kit or just the turbo? A good turbo to run is the Garret GT line, something like the GT25RS. They can handle some 300 horses and are ball-bearing, so they spool fast. Check out www.c2power.com [c2power.com] if you want a good full kit.

To calculate the power added by boost, you need to know a few things. First, the atmospheric pressure of oxygen is ~14 psi. Second, you need the engine output (say 180 in your GTS). If you push 7 psi, or half the psi of oxygen, you are in effect adding 50% more air into your air-fuel mixture. Then you add 50% more fuel to cope with the increase in air. You then essentially add 50% more power to your car, which would put it at around 270 hp crank. 10.5psi would be 75% more, putting you at about 315 hp crank. Take this all with a grain of salt, though, it is merely theoretical.

ok cool thx for that man
so what would be the max PSI i could run on a stock GTS?

6-7

and how much for a 10-12 psi turbo with all the stuff needed to add it to the motor?

If you lower the compression, get forged pistons and rods, stronger head gasket, and proper tuning, you can push 14, but really any higher and you are tranny limited. The Celica tranny is weak, you can't push insane power out of it. C2 Power has a set of stronger tranny gears. You can send your tranny to them and I believe install is free, but you have to send the tranny to their shop in Hungary and pay around 900 or so for the gears. Another option is cryo-treating, but I don't know of anyone who's tried that.

6-7 PSI owww i want to run 10-12 what upgrades do i need for that? cost?

ohh only 6-7 PSI what mods do i need to run 10-12 PSI? cost involved?

Let's see. Well aside from the 3800 USD for the kit itself, you're gonna spend about 800 on install (assuming everything goes perfectly, which it rarely does), 275-500 for gauges, 350-500 on a boost controller, 100 for a turbo timer, 400 for a new clutch, about another 400-600 to install that new clutch, 100 on a stronger head gasket, 300-400 for the custom exhaust, 400 or so for lower comp pistons, copy that for the connecting rods, maybe another grand on hotter cams if you so desire, and that's all before install and tuning.

does my car have LDS? how can i check? by doing a burnout and seeing how manny tyre marks are on the ground? my car seems to have lsd im ot sure tho any help

what do extractors do and i have heard about getting aftermarket one that give you HP gains is this true?

hey celicaboy wassup?

Extractors? I have no idea.

LSD. No, you don't got one, unless somehow you have the TRD Sports Modelista Celica, which I'm 99% sure you don't. You may feel as though you do because our cars handle awesome to begin with. Another way to test for LSD (which you don't need to do, but it is fun) is to take a turn in a neighborhood at like 40 or 50 and listen for tire squeal.

Oh, and try to put all your questions in one post and then wait for an answer.

i have an auto so would i still have to get the clutch?, i have E-shift though

Oh, it's an auto. Well then, yeah forget about the clutch. Also forget about getting the C2 tranny. I'm not so sure about LSD either.

ok 2 questions how much for a good CAI?
how much for a turbo that will run on my stock engine?
= witch one should i get (your opinion)????
thx

hey combat dont mislead munted turboing an auto us useless and will cost too much especially since he has a gts amd will pretty much have to rebuilt his engine to handle the the turbo
and did i mention the big time turbo lag youll have

munted your best bet would be CAI, exhaust, header, pulley and n2o and even with that fastest youl go will be low 16 in a 1/4

do a search bro this has been discuss many many times

True. I didn't know he had an auto until after I posted most of the stuff. With an auto GTS, you're better off making a show car, because you'll be disappointed with all the money you'd have to pour into your car to make it fast.

yup

i have an auto but it has E-shift with an auto clutch make any diff?
and also right now my car already does a low16 stock i have a celica SX witch is an australian model i dunno if that makes a diff?
i got the chip fixed up so i gan rev out to 4500-5500rpm then let off the breaks and also sports shift is apparently as fast as the manual i have read at a toyota web pag so...

i have raced a stock manual sx b4 and i was slightly faster

^ do you seriuously want us to believe that??

you where doing good until your last 2 post

we have the same car bro and iam no where near 16's
there are no ecu chips for the 7th gen celi that would raise the rpm


try again riceboy

lol is there a way that i can delit above

Nope. Just admitting you were wrong is the best way to cover it. That's another rule around here, if you're wrong, don't pretend you are right.
