3sgte stroker, i finally decided on my spare 3sgte... Options

what dictates the displacement of a motor? Its bore and stroke. If you look at the specs for the stroker kits on the market you'll see the bore and the stroke are identical to that of a 5sfe.

it's been done look here
it's been done if I get the parts & money I will do the same thing

Chris K is who I got my pistons and rings from. Hes a VERY nice guy and is willing to go above and beond to help anyone out. My shop stayed in touch with him to keep my crank machined to his specs while installing my rods and pistons.

That's not what I meant. You said rods/crank/pistons are the same. I highly doubt that. I doubt the crank journals are the same (5SFE vs JUN stroker), I doubt the rods are the size/length, I doubt the actual bores are the same, the 5SFE being an odd number (87.5mm). I honestly am not even sure if the 3SGTE piston pins are the same as the 5SFE (press fit). Again I'll say, I'll stick to my gut. Stroking with a stroker kit that costs more than the swap itself, or is the cost of 2-3 spare longblocks... just doesn't make sense... because the torque advantage just isn't that great.

I will do it to since you know him how can I get in touch with him???

I dont think I have his email or his phone number any longer. Just create a post about him at MR2OC and he will show up. That will most likly be quicker than me finding the recepts.

ok cool!!!

i did this set up with all stock parts an the car runs nows

ATS Racing 2.2 Stroker

There is no replacement for displacement. By adding approximately 10% more displacement to the original MR2 engine customers are finding much quicker turbo spool up, better driveability, wider torque curves, and excellent low rpm response. The ATS 2.2 stroker short block is built from a 3SGTE block so there is no additional fabrication required for installation. All accessories, oil and water lines bolt up just like factory. Each 2.2 stroker short block includes:

3SGTE cylinder block - bored, checked, decked as necessary

5SFE crankshaft - machined to accept 3SGTE connecting rods. Cryogenically treated for strength and hardness.

Reconditioned 3SGTE rods

How much did the stroker kit cost you, Punch? Would like to hear about it. Don't think any of you remember me but I once came here a few months ago looking to buy a Celica, asking a billion questions... now I'm looking for an MR2. I drive an Integra for now (I know.... GTFO Honda!)

Sorry for the thread hijack... anyways just wanted to know how much it cost for the kit? Couldn't find it anywhere on that Aaron guy's page.

it says "Prices from $2300"

I'm dealing with this exact same debate with myself as i type this. The 5s has too high of a comp ratio to boost very much past stock 3s if even that. the work and cost it would take to build a 5s-gte hybrid engine would be astounding, and i'm not saying it wouldn't be possible or that it wouldnt be good, it's just that you're basically building an all engine car that you end up turboing in the end. if you machined all of the parts precisely to their potential and tuned the engine right, it would produce a fair amount of hp and tq. but unless you go stock engine components, the bill for the rods, pistons,(which a company called JE makes for the 5sfe block with 3sgte head) head (incl cams, gears, valvetrain etc) would be at LEAST 5grand for good parts. I've decided the best way for me to go, and that's primarily for my use of the car and budget, is to swap the whole shibang out for a 3sgte which goes in almost perfectly bc the all-trac gt4 is virtually the same car with a factory 3sgte and awd. I need to get a 5 speed manual tranny in mine also the pansy i bought it from had a 3spd auto .....*crickets chirping* *wolves howl* *tumbleweed bounces by*. it is ok until around 90mph then it almost loses all power bc the 3rd spd redlines and the engine forcibly kicks in o.d. which has almost no power since it is designed for economy and low rpm travel. i got a quote from a garage where i live to have a full 3sgte swap incl labor and all parts for $4500-$4700 depending on labor but everything i've seen heard and read says it goes in the st202 bay very easily

The 5S-FE has a 87mm bore x 91mm stroke = total displacement 2164cm2
The 3S-GTE has a 86mm bore and stroke = total displacement 1998cm2

According to this site: http://www.junauto.co.jp/products/cylinder...aft/3sg.html?en

Jun stroker kit have a 87mm bore x 92mm stroke = total displacement 2188cm2

this is about the best deal on a stroker kit you will find

i am a die hard MR2 guy and i can tell you from copious amounts of experience that the 5s block does mate with the 3s head. TTE 1.2mm metal head gasket and ARP hardware FTW!!! the 5s crank is way beefier than the 3s crank but it would be wise to use 3s rods and pistons. 5s rods and pistons can be used, but they dont stand up to the rigors of 20+psi.

[Punch]

wow this is still talked about....
look all the guys runing 9-8-7 sec rwd 1.8 corolla wit a 3s has 5s blocks and cranks. the whole 5s block 3s head been going on for a long time they get pistons and rods for the 5s (raceeng.com) the set up cost less than a stroker kit! o! always use a turbo oil pump...
