lsj head on le5 block
WRONG he used the pcm from his 2.0, there were a couple of things that needed to be changed though for his anyway He wanted to use his exedy stage 3 clutch but the flywheel wouldn't bolt to the le5 block so he had the holes filled and drilled to match. after it was all said and done with the m62 on it and a 3inch pully he put down 265whp and 290ish tq. he had one dyno of over 300 but it did not print and was on a crazy ass tune. So trust me I helped build that motor i know it can be done. this peticular motor was built for a big ass snail shell anyway. a guy on here chevytech007 bought the motor and trans from fullthrottle when he traded in his redline, only paid 1000 for it.
here are the dyno numbers

whatever man all im saying is it can be done and its really not that hard at all. if you have a 2.4 and want to drop and lsj in your car then yeah you would have to have your pcm or computer reprogrammed. I didn't try and make you sound like an idiot...you did that one all on your own.
don't get ass hurt. it sounds like your the nooob. Im not ASSuming anything. So go grab a coke and a smile. there is no need for you to be acting like a A hole.
He actually did a little more than that. not really that big of a problom just find a clean ECM from a ss/sc and your golden.

italicized...basically thats what i said on the first go around....but you had to be a noob and try and create some idea that was totally aside from what i said....
underlined...ok? im the noob? thats why you tried to explain something to me i already knew had been done. i knew it when it happened...i remember the original post. secondly, you did assume. if you hadnt, we wouldnt be talking about a le5/lsj combo motor. instead, wed be talking about doing a complete engine swap.
thirdly, im not a noob and im not acting like an a-hole. you came in here, assumed you knew what i was talking about, and then proceeded to post results of something clearly mentioned earlier in the thread, and then decided to call me lazy and tell me to use the search button. moral of the story, dont assume, and admit you were wrong. i dont get ass hurt over punks with smartass posts like yours. thank you and have a nice day

haha i dont believe you see any e tears comming from my e-face....grow up

oy vey.. first.. this is pointless .. it'll be more worth then is worth it in the long wrong.. yes while it'll fit on there.. it'll **** with the computer.. and since we can't make custom os's we wouldn't be able to fix the VVT issue unless something in one of the extra efi live tables gives that options.. further more.. you can't just " drop in a lsj ecm" like you say stryder.. there are ALOT of things different.. first off it's setup for a car that factory runs boosted.. so it'll be looking for a bunch of sensors you WILL NOT HAVE>.. scip, boost, 2.5 bar map .. those are just a few... if you're looking for a better flowing head.. get the 2.4 head ported and polished..
as far as the frankenecotec.. there was ALOT of work for him to get that to work.. and he almost gave up a bunch of times due to complications.. i wouldn't suggest it to anyone.. as it's not cost effective.. it was good for him because it gave more displacement and higher compression then a stock lsj (but lower compression then a 2.4) as well as better flow from the lsj head..
you can't just swap **** out and expect it to do easily.. tuning the 2.4's is a totally different animal then the 2.0 because of features they each have individually
you need a reality check if you think you can just drop in something from a totally different motor and have it work with little effort.. we're not honduhs.. yes the bolt pattern is the same for alot of ecotec parts.. but that don't mean **** when your car wont turn over without a new tune and you have no idea how to fix any of the problems you've created..

Anyways Like someone stated before WHY would anyone swap their lsj out for an le5? Its not as hard to do something the second time around since the bugs and issues have already been found and taken care of.
the issues with swaping an lsj head onto a 2.4 car are totally different the the issues mvp / fullthrottle came into
well...why not?the le5 block has everything the lsj block has plus some iirc. swap pistons and rods into the block, and your good to go. the engine has the potential to be superior to the lsj block. it just doesnt have the equipment to get it there. but thats not a problem. pistons and rods can be had for a thousand or so. in truth, when you take the blower off the lsj, it isnt a superior motor. just a debored 2.2 with some modifications to handle boost.
