will this 2.2 kit fit the lsj block, after looking at the build book the only thing i know to be different that would cause an issue is the piston to bore clearance is smaller on the 2.2 pistons vs the lsj, and they both use the same bore. it would seem that the bearing end of the rods are the same size as well, but the pin size is smaller on the 2.2, but of course the aftermarket pistons and rods would be sized together i assume.

im sure this has been asked, i looked it up and alot of the answers are about the pin clearances i only care about the piston to block clearances.

I'm honestly not sure myself. But if you're looking for pistons or rods (or both) for your lsj, I have both on sale (bnib) if you're interested.

the 2.2 uses the same bore and a .033 longer rod and a longer stroke crank the part will physicaly fit and work but as for the comp ratio I couldent tell you. you would be better off buying the correct stuff for the lsj as it has a different rod length and a shorter stroke

Mrb is right.

If u do the math u might be able to buy a hella thick hg to make it work. But its now worth it just use the correct parts for ur engine.

Would that be a good kit for my Turbo 2.2LAP?

Oh ya..
Im not sure wat the difference is between the lap and l61
I would think the bottom end parts r interchangeable. I think the LAP has a different head

i did not think about the rod length hahah. i should have checked that first. ill probably end up with just some diamond racing pistons and rod, or just stick with stock rods.

LAP has VVT, i think thats the only difference.

Sorry to steal the thread! :cssNET:

You should just buy forged pistons and then buy sleeves through mrB. Do it the right way, and you def. Won't be disappointed

didnt think sleeves were an issue, but ill look into it. im using lk9 blocks, i have the engine in my car and a spair, and i just come to find out during my auto to mani swap my headgasket is blown and im going bigger turbo, so i have to decide whether to pump money in now for arp's and head gasket, or just go stock studs and save the arps for the other engine, and build that later. i already dumped alot into the turbo setup and working the swap.

im only running a t3/t4 so i figure stock engine should be good to about 350whp after seeing everyone else's success.

the thing with the sleeves is just dropping a set of forged pistons in the stock bore the piston to cylinder wall clearance is more then likely going to be to loose and if there is to much taper and the bore is out of round the rings wont seat in as good as they should

You need a 2.2 crank to use that kit. If its an LSJ engine you would need the pickup wheel off the LSJ crank also

For sure if the block is high miles. The forged pistons require a least 3 thousanths clearance and that can be checked by a good machine shop

Yeah well the extra block is fairly low mileage. Honestly it will come down to how much money ill have in my pocket at the end of next year, but I will probably consider it only because I have a goal or 500+.

I can get you molnar rods and diamond pistons for $815, if you want k1 rods just add $25. We normally stock these parts also.
