yes unless you know what you need to do properly to stroke it dont do it yourself. ZZP you might pay but you'll wish you had

So did you build it yourSelf... what kind of power did you see...

My bad I didn't do it, I was just saying. I accidentally typed yes

Oh ok i know that the le5 crank is cast iron and the lsj is forged...big difference in strength there..i build engines for a living..i have access to all the tooling to make it work i was wondering if any one has done it out side of zzp..i just can't justify spending that much money on a engine Wen i could do it for 1/2 the cost of less..i can
get a brand new le5 crank for 320 shipped to my front door.
I have another thought to combine the zzp 2.1 lsj block with the 2.4 crank...should come out to be a 2.5 lsj. Any thoughts about that

I believe all the ecotec cranks are the same? I can be wrong but that's what I was told its all rod length and such

lsj-86mm bore, 86mm stroke
l61-86mm bore, 94.6mm stroke
le5-88mm bore, 98mm stroke

le5 crank in lsj or l61 gives a 2.3l, lsj or l61 crank in le5 block is 2.1l. those are the only combos you can build with stock blocks/cranks. you cant get a 2.5l, at least not without boring the block or a custom crank.

Hmm ok thanks for the info..makes sence..wat about a 90mm bore in a lsj block and the le5 crank..i can have JE forge the pistons and have darton make the sleeves and i can bore the block for larger sleeves..i wonder wat it would take to get a head gasket made?

I just don't want to snap a the cast le5 crank. That's y Im asking. Cuz my plan is a s259 turbo step up after that.
