Celica Forums General Discussion Exterior Stroker Kit

This is something which you guys seem to avoid talking about... " The 2000cc stroker Kit". I think this mod is very good cause increasing displacemnt is key to HP and torque gain. And as the saying goes " there is no replacement for displacement".

If we want to compete with the Big Dogs like the mustangs, corvettes or even skyline and supras we need to look at forced induction and stroking.

give me all your knowledge and insights with pics and details about installing the stroker kits as well as the manufacturers for the Celica GTS stroker kit... the only one I know of is Brash Boy's stroker kit.

monkeywrench racing does a stroker kit. but i think it is only for the GT engine.
it has the option to go either NA or FI with two different compression ratios.

here's what they do for the GTS http://monkeywrenchracing.com/mwr_toyota_2zz_ge_piston_and_sleeve_kit.html
i tpretty much is just beefier internals with the option to chang ethe compression ratio.

Does the block have to be bored in order to install the stroker kit in all cases?

most likely since you have to have the block machined to put the stronger sleeves in.

*drool...*

doesnt trial do a stroker kit? but i think that puts compression up to 13.1:1 or something like that...defintiely dont wanna be having forced induction with that sorta compression...

trial does what they call a '3zz engine' which is basically a 2zz stroker kit.

well at least its not very expensive

wut is a stroker kit?

A stroker kit is a modification which increases your cc rating ...i.e in the case of the celica GTS from 1800cc to 2000cc this significantly increases horsepower, I think plug and play it brings your celi to about 220hp.

The kit consists of connecting rods, pistons and crank

hey Guys,

Listen to this... If you put on a stroker kit yes it normally requires you to increase your compression ratio thats if you are going strictly N/A.

If you wanna go forced induction then you have the option of lowering your compression ratio to a safe 8.8:1.

If I get 250hp to the wheels plug and play with a Turbo kit on an 1800cc displacement stock engine, can you imagine what you would get with putting that Turbo kit on a 2000CC engine. you would be cutting nissan skylines... MAD SPEED!!!! about 300hp---->500hp to the wheels.

No and No.

You do realize that the Evo, WRX, SRT-4 and such all run more than 2000cc with Turbos and produce <300 HP

Actaully, the evo is, if anything, slighty under 2000cc, and with a few Turbo mods (change in boost and such) and a total of about $5-8k, an evo can put out well over 600 WHP. And the awesome thing is, one may may be in my near future!!! Also, those cars come tuned to be street legal, and horribly robbed from their true potential. Oh, and by the way, evos kick out 271 HP, WRX's and SRT-4's about 240HP

First of all you have to look at the potential of the engine, the evo and STI are very low compression engines.

A stock evo runs on about 15Psi boost and gives 270 to the crank...thats about 240-250 to the wheels. A stock celica with a Turbo kit running 7-8 PSI gives you about 250hp to the wheels. Because of the high compression ratio the power output will be comparable.

I haven't seen a Turbo Celi put down 250 at the wheels. I'd like a dyno.

Besides that, anything more than 6-7 PSI on a GTS (which you have) and you'll have to lower the compression ratio or seriously reinforce the internals, then find some serious octane gasoline.

Wasn't Thunder Celica ~450HP?

I agree with you about changing internals with an increase in PSi when you Turbo an N/A car like the Celica. things to consider are the axles,larger injectors,larger fuel pump,fuel pressure regulator, pistons ,steel clutch and maybe even the gear box,But with the right kinda engineering skills, you can get 500hp or more to the wheels of your celica GTS.

have a look at the power you will get by plugging an XS engineering Turbo kit to your stock celica with no change to the internals.

90+ WHP gain

A stroker kit will increase hp to some degree...but what you haven't hit on is that it is the most effective way to increase torque!!!...and a little known fact about the GTS engine is that you can stroke it out to like 1.93 liters just by swapping in the GT (1zz) crank!!! (per ecelica member Illusive)...think about that before you go and spend hords of cash on the trial or brashboy kits

That's crazy cool ... I like it!

Then Turbo the 1.93 litres and away you go.

Expand a little bit more on the swapping of the GT(1zz) crank you are talking about send some pics.

no pics...I"m just talking about taking the 2zz crank out of the GTS, ad putting the GT crank in. The 1zz engine has a longer stroke than the 2zz, and putting the 1zz crank (because it will fit) into the 2zz will give it more dislacement, and probably give you a lot more torque down low ...pm ecelica member Illusive (mostly found on the racing forum), and he'll tell you more than I could

wow i didnt know that. good info azzkikr!!!!

that's what I'm here for

actually swapping the cranks like that is a terrible idea, you're going to kill the reliability and longevity of your motor with that kind of stroke, there is a reason why the GT doesnt rev as high as the GTS and thats because of its higher piston speeds with that much larger of a crankshaft. When you increase the stroke you increase piston speeds, increase piston side-load, and decrease R\S ratio(unless you spend lots of money getting custom rods and a deckplate machined). If you really want to increase displacement in your motor then the best way to do it is to increase the bore to 85mm which would make it a sqaure motor. Anyhow by doing this you would increase the displacement to 1929 cc vs 1932 cc(stroker). If you use the same piston dome CCs on the new pistons this will yeild a 12.32 compression ratio

Jesus that trial stroker kit is expensive.

you want a picture of a crank ? they pretty much look the same ones jsut a hair bigger

if you want a picture of one you shouldn't do the mod have some one eles install it

and all this talk about stroknig and no one has mentioned that it will also take away from that red line

more rotating mass = lower redline

unless you spend uber money

If your rev decreases cant you put on a lightened fly wheel to increase your rev??

what I am looking for you to tell me is not necessarily how to run the celica with increased stroke non Turbo..but how to increase the stroke, decrease the compression ratio (using domed pistons, thicker gasket or bore) then go boost.
what I am looking at is bringing the motor to a comparable configuration as the stock evo engine...low compression with boost running safely.

its rotating mass and wil lhelp make the rpms rise faster but its two diffrent types of weight
the stroker kits make the stroke longer (hence the name) this means the piston is traveling a relatively long distance up and down in its cylinder on each cycle. our stock strokes are smaller so that we can rev higher The piston in our stock engine has a large diameter for the engine size, and it goes up and down a relatively short distance on each cycle. This means that it can rev up to its high rpm

if you can sneak some peaks look at the redlines on some other vehicals like a v8 camaro a v6 camaro a disel truck a crotch rocket

rpms almost always increase as engine size decrease (why my 600 cc crotch rocket can rev to 12 k and love every minute of it compared a to a disel's 4 k redline)


for another compare look at the stock stroke for the gt and gts
gt 3.60 stroke (6.8k redline)
gts 3.35 stroke (7.8k redline)

Face it guys, Celica is not supercar. You would be better off spending that kind of money towards a faster car

amen, but this post is amazingly informative

...agreed ...

actually it's a lil more involved then simply throwin in the 1zz crank. you still need whats basically listed on trials website. it's just prolly a lil cheaper to piece it together yourself then buying their name.

with the right setup and tuning a stroked 2zz should see closer to 220 whp then crank hp. lol probably even higher.

nobody talks about it because its very expensive to do and requires a lot of effort to do. most the celica people you'll find like to stick with simple bolt ons and caim their car is slow.

some guys swap the 3sgte for the 2zz-ge and it is actually a much cheaper conversion than buying and Turbo kit and stuff.

not those in emmisons states thats illegal lol

I seriously doubt that.

^^^ yeah for real

It is actually not about engine size so much as piston speeds, how about a 3.0 liter v10 BMW F1 car reving to 20,500 rpm? They use small strokes, many times less than 70mm. Nearly all high horsepower NA engines have small strokes with oversqaure bores. Hence you can have a much larger final drive.

No, you need to look into a new car.

Your FWD 1.8L Toyota econobox will never be the same as the "Big Dogs".

OK, fine, you stroke it out to 2.0L. Then what? Turbo? Fine, Turbo. Now you have $0, a 2.0L FWD 2ZZ-T, and absolutely no traction under any conditions. Have fun creating a custom suspension setup that will counter all of the torque steer that you WILL be experiencing. Don't forget to buy a few beefed up transmissions, they won't last long.

A 2.0L 2ZZ-T is not the same as the 4G63. And it never will be. Once you are at the limit of the 2ZZ, the 4G63 is just getting started. By the time you performed every last possible modifcation to the 2ZZ, the 4G63 could triple your power output. Just because two motors have the same displacement and layout does not make them the same. The 4G63 was built to make power, the 2ZZ was built to get good gas mileage.

The Celica is not a racecar, leave it that way.
