Building a stroker motor
Yeah, I have an 06 SS/SC. I am going to go with JBP's 3" exhaust from the tuned headers back...Oh, and I wanted an EVO, but my parents wouldn't let me get one because my father did not like the dealership, something from the past, and they don't get good enough gas mileage...damn, but I have really fallen in love with my balt.
Greetings! I would like to pick all of your brains with some quick questions. I am looking into building/purchasing an LSJ stroker kit/built stroker motor. I want to run a lot of boost from a fully ported and polished M62 blower and have it as my everyday driver. I am beginning my long list of researching now so I can begin saving for an already built motor, or start buying up all of my components necessary.
I greatly appreciate all of your help and can't wait to begin buying my new parts.

And here is an LSJ one. I got this picture from the GM LSJ build book. 8 bolt with a screwed on ring.

I'm very curious now about the Eagle crankshaft that has the option of with or without timing ring. If you get the one without the timing ring, can you put an LSJ ring on there? I'll email them and ask. See what they say.

Email sent, let's see what they say.
It appears the rings are in identical locations. Another option would be to machine an L61 crank to accept the screwed on LSJ ring. It would have to be a precision machine shop job, but it's possible.

How did I miss this thread? Least all my questions were asked. This 2.2 stroker idea is looking to be more of a hassle than its worth. Wish someone would just make better rods for the LSJ.
I tried getting a hold of fullthrottle who did your cams, he has a 2.4 bottom end with LSJ head and is using the Exedy clutch for LSJ if I recall. So he has somehow gotten it figured out cause the LE5 crank is 6 bolt as the L61 I believe. He hasn't gotten back to me yet.

Very nice, how much can we bore the LSJ block over without running into overheating issues? I guess you can always sleeve it if you go too much....how about the L61 block? how much can it be bored over? I can slip one of those 2.2 sons of bitches under there and up displacement really easily.
We don't know yet, I guess that is why. I just want something stronger. Even though they are forged, they are still OEM rods and probably not as strong as aftermarket. But like I said, no one has ruined a rod yet in the LSJ. I just don't want to open up the motor again incase something would happen to a rod.
yall are out of your minds. You say you want a reliable daily driver with 500whp? IT DOESN'T EXIST IN A 4 CYLINDER!!!!
The amount of time and money you are going to put into this in the name of getting more displacement is unreal.
You want more displacement? You can turbo swap the 2.4L engine in the SRT-4 and beef everything up for around 10k and make well over 400whp and have it be far more reliable than a bottom end from one engine retrofitted to the head from another engine. This just screams disaster and it's going to be a ******* expensive disaster.
If you're doing it to be a pioneer, I wish you the best of luck, but mark my words...this will be a disaster and you'll have a car that cost you 38k that doesn't make it to the finish line on a 1/4 mile drag track. You'll just swap in a LSJ crate engine and be pissed you spent that much money to end up there.
Another option? Buy a mid 90's DSM turbo, swap the internals, get a big ass turbo, pay a shop to do all of this for around 12k fully built = 4-500 AWhp and burn up the quarter between 9-11 seconds, and drive your GMPP stage 2 LSJ to work everyday.

I don't want no 500whp. That will not be a daily driver.
All I want is something different that everyone else is doing. Plus I love doing motor work. What ever amount of power it gives me, I will be glad and take it.

And as it has been stated in this thread, people have already done this with the 2.4L block and 2.0L heads on a Redline.
If you have enough money, anything is possible sir. A reliable 500hp street machine may cost a lot, but it is really possible. Yeah, I love torque and I went to the track tonight and talked with some fellow LSJ owners and they say they are working on a 2.2 ecotec bored to 2.3L! Theirs should be down relatively soon, I can't wait! So, I am going to look further into that idea tonight and see what I can find and post up. I have a friend with a pre ecotec 2.4 stroked to 2.6L!!!! It sound ******* mean, I will look for the link to the video and see about posting it up.
All I could pull out of my car was a 13.9219 @ 100.81. Yeah! I have a 13 second car! Now onto the 12's...

Well I decided to scrap my stroker build idea. After seeing the reluctor is cast, and my flywheel/clutch won't match up, I decided it wasn't gonna be worth all the extra hassle and money. Keep my square motor and just make up for it in boost, lol.
Good luck with your build, keep us updated.
