I was thingking about boring out my lsj block and using a 2.2 crankshaft and eagle or wiseco 2.2 rods and piston. Is it possoble or should I stick with the 2.0?

 

its possible just a little harder to tune it with a 2.0L pcm

 

Why will it be harder to tune? Regardless I'm want to get my car tuned by intence or ZZp.

 

you would need to run 2.2l crank rods and pistons to make that work. you would need an 07+ crank with the 58x reluctor wheel, and may need to bolt the 2.0l wheel onto it. the other big difference is the flywheel is a 6 bolt on the 2.2 and 8 bolt on the 2.0. not sure what you would need to do with clutches there.

 

You dont need to bore, they have the same 86mm bore. Its the stroke thats different. You would need the 07 crank, like said from sparkey, and a flywheel from a 2.0 but made with the 6 bolt pattern then you should be able to run an lsj clutch without an issue. The problem with that, is if want to get a custom flywheel made like that say from SPEC, you must order 10 at a time. Not worth the money for that little extra displacement.

 

i guess a guy could switch to a f23 tranny at the same time, and he could theoritically run a 2.2 clutch w/out any issues, with a 2.2 flywheel, but than ur looking at like i said earlier trying to get it tuned, i believe the flywheels have different amount of teeth

 

From what I saw at harrop does custom machining. Thank you all for the input. I guess a custom crank seems like the easer route.

 

Yeah but i hate the F23... It can handle some power but the gears blow IMO. You cant even make 60mph in 2nd gear w/ 6500rpm redline. Now if you ran it with a 7500rpm redline im sure it would be better.

 

Im planning on keeping the f35 cause I want the six speed swap. I'm going on deployment soon so I will be saving up all my money. Well the main reason I was thinking of stroking my motor was so that way one of our sources can catch on and maybey make one for those of us who want a stroked motor. Thanks to all the input and knowledge from you all I'm one step closer to stroking my motor. I'm trying to find out if one of our vendors does any custom machining.

 

For quite some time we have been considering this as a project.

We currently make stroker cranks for the LS1/LS2/LS3/LS6, and several custom products for V8Supercars and NASCARs.

Before getting too excited, we need to better understand the requirement and market. We can obtain most of the technical data from GM (we have a very good relationship with them ) but some market info from you guys would help ...

1 - Is it mandatory to have a "kit"? We do not have ready access to pistons/rods/bearings/gaskets etc for the EcoTech, so we would only be supplying the crank and reluctor wheel.

2 - What is a reasonable price? Be realistic ... what is the most you would pay to get the crank (with reluctor wheel fitted)? Perhaps consider other similar vehicles and offer the street price for a comparable product.

3 - How many of you would actually buy one as a crank (not a kit)?

id be willing to supply a spare bottom end if u need one

 

Ive also got a full stock bottom end L61 sitting in my garage i wont be needing. If that helps you guys out. I would be willing to go with a 2.4 crank with the 7x reluctor ring setup so i could fit it to my ecm without too much issues. Now that there is real tuning for the e16a i could have a sweet 2.4 turbo with a built bottom end.

Price wise, the eagle forged crank is what 799? I'd pay $500 for a 2.4 crank w/ a 7x reluctor ring to throw into my 2.2. As long as its still good for at least 600hp. But you would have to have it done by mid april because im not going to take apart my bottom end again for a long time unless i have to.

 

I'll shoot you my thoughts via email today after work.

Thanks Ken.

 

the thing is we can build a stroker motor with a 2.4l crank (98mm stroke), the big issue is the flywheel. if there was a flywheel for a 6 bolt crank and the f35, that would open up a lot more options, 2.2l and 2.4l cranks aswell as the eagle crank. the way i see it, we dont need a stroker crank built, we just need an f35 flywheel that is 6 bolt.

as for rods and pistons, id say build it around eagle rods (small pin) and come up with a piston for the 2.4l around 9.5:1 compression and a supply people with a build number from wiseco (or whoever) so they can order the pistons up without hassle.

 

+1...

not only would this open a market to the 2.0 guys, but 2.4's would then be able to swap to f35 trannys easier. I paid ~400 for a spec flywheel, I'd pay up to about 500 for the same 6-bolt flywheel that would allow an LSJ clutch...

 

This would be an incredibly unwise decision.

First, there are different flywheels available for different aftermarket clutches that are not the same dimensions.

Second, an LE5 crank will not swap into an L850 block without suffering structural comprimise.

Third, the stroker crankshaft that would work would be the L61 crank. 06 and prior units would not work with the LSJ crank reluctor ring. The 07+ may but will probably be on a different center similar to the LE5 reluctor ring since they use a hall effect sensor on the gen 2 block.

Bottom line is, if you swap to a different production Ecotec crank, you almost certainly have to swap blocks as well or in some cases a different PCM.
