I've yet to see a production block handle 1/2 studs know one ever does it right and they think they need to go past 80ftlbs you need a little spring there to absorb shock you should also consider going to a 3.45 bore it makes the head pickup Airflow(almost 30cfm) in the .330 to .350 lift a 3.500 bore will even more and your sleeves will more then handle either bore size
ive found a brand new gen 3 2.0l block, actually several of them. whats everyones thoughts on a gen 3 block limits? always remember it being "600hp", but im unable to find anyone thats had a failure, and found several people talking about running well into the 600hp range. i know css can put a deck plate in them, however im a little on the fence on that seeing they cant (easily) be resleaved, and im concerned about distortion and having to bore the block after.

the gen3 stuff is ok i think the lsj is a better block but i have seen some people pop a gen3 at 500hp and ive seen them go 750 and live.flatgod has the best setup you have the option to change a single sleeve you can increase the bore to 90mm (which you should) the bigger the bore the better the head works at low cam lift
i decided on the gen 3 block, at least for now. wish i wasnt put in a predicament where had to make a choice in somewhat of a hurry, but it is what it is. i have always leaned to the lsj block with either a cylinder support and drop in sleeves or darton sleeves being the best option. that being said, ecotec blocks, at least where i am are getting a bit harder to find. if i had the time id wait to find the right block, but being realistic with with machine shop back log and inevitable delays, i done have the time. ive got a drag and drive event in june, i need time to break in and tune, testing, etc before then. realistically i need the car running in march, which sounds like a lot of time, but in reality its not when redoing pretty much the entire engine bay.
im now just debating weather i toss my old 2.2l rotating assembly (eagle rods/wiseco pistons) into the gen 3 block and use all the new 2.0l stuff i bought into an lsj block later, or just build a 2.0l in the gen 3 and call it a day.

When I originally did the build almost 10 years ago, all the parts I had acquired new from people who wanted to do big things but never did, hence the stock piston bore. I think the diamonds I used were originally purchased from intense performance if that gives you any idea how old they are. In the event of failure that required more than 1 piston needing replacement I'd absolutely be sizing up.
well, been through hell trying to sort this out. bought a brand new gen 3 block on ebay, the seller screwed me around for a month, never shipped it. i just got through the refund process and got my money back, but a month wasted and i still have no block. feeling defeated, i decided to have a closer look at the l61 block ive beat the hell out of for 15 years. bores are out of round, 2 of them close to .0015" and with some cylinder taper. with too much piston to wall already i dont want to hone it, so i just decided im gonna put a fresh set of rings and bearings in and send it. but before doing that i decided id give the honda life a try with a pour in closed deck.
filled the block with sugar to roughly 5/8" below the deck, packed it in and smoothed it out and filled the block with Devcon F2 liquid aluminum. once it cured i set a head gasket on and drilled the coolant holes through the epoxy and drained the sugar out. ill flush the block with water, and may fill it with boiling water to make sure it gets all the sugar out.
im going to stick the 2.2l rotating assembly back in and continue to run it for this season while i sort out my other engine. doing this will actually help me with all the other changes ive made to the car this winter (everything from the turbo outlet to the intake flange is new).
I love it. Interested to see how well this works. Lotta people on forums just want to **** all over peoples ideas and trying different things. I'm well past ever doing something like this but really enjoy other people trying stuff out. Honda guys have been doing this kinda mod for years with varying levels of success. Keep us posted.

i figured i was past doing something like this, but when i cant seem to get the right thing done, well, this happens lol. i figure the motor owes me nothing, id never build another ecotec with this combination, and its worth nothing to sell any of the parts, so why not give it a shot.
im actually surprised we havent seen more people try this on an ecotec.
