block difference
 

any one know the difference's between blocks of the 2.2 ecotec, lsj, and the 2.4?
i have a 2.2 block that i wanna throw a lsj crank in it and build it as a lsj, but just with a 2.2 block because i have it

anyone know?>

The only difference I see between the two blocks is the bore. I belive if you wanted to build off the 2.2 though, you'd have to utilize the 2.2 rods as I believe they are a different size....but I may be wrong...someone help us out because I would love to be able to convert to a 2.4 block

well from what i understand the bore between the 2.2 and the 2.0 is the same. Rods are different where they meet the crank. which i would use the LSJ crank anyways because the 2.2 crank i have has a 7x ign trigger wheel on it, and the lsj has a 56x trigger wheel. I'd like to tune with HPT so the 56x trigger is needed.
i know the lsj head will bolt onto the 2.2 because someone on JBO did it.. But is there any other differences like sensor locations or anything that wouldn't be expected.

i'd hate to build the block and then go to swap it in, and things don't line up right

iirc, the 2.0 s/c, 2.2 and 2.4 use the same block. the 2.4l may use different sleeves for the bigger bore.

thats what i thought i remembered also, but wanted to verify for sure..

hmm now i need to start looking for a lsj crank

well there is a difference bettween the lsj block and the 2.2 ecotec this picture is the lsj where the oil filter is!

this is a brand new 2.2 bates engineering block that im building my motor from its got an oil filter block off plate so i can put a screw type filter on these are the only difference i have found bye looking at the two... hope it helps

all the Ecotec bores are the same.

the bates motor is different than all the stock blocks. because the every 2.2 i have ever seen has filter in the same locating as the lsj...including the one in my garage

yea the bates block has the oil filter housing cut off and the plate made to run a remote filter. the gm build book talks about this mod. all production blocks have the filter in that location, however it looks like it may be different around the filter housing for the lsj oil heat exchanger, the l61 doesnt have that.

The oil filter is located in the same place an all balts. If you look closely, the filter housing is a bolt on unit and the little black studs with the holes is where it goes.....

Just to correct something, the trigger wheel is 60-2 aka 58X on the LSJ and all 05+ L61's.

Def not...

thank you, i've coming from jbody territory were all the trigger wheels are 7x in the l61.. and the engine i have has a 7x trigger wheel

I think the 2.4 is one of the new GEN II blocks, not sure about the 2.2 or LSJ.

Edit-just looked, the 2.4 was the first of the Gen II blocks, the 2008 2.2 uses the new Gen II along with the LNF. The previous 2.2's and the LSJ use the first Gen block.

an article on the 08 2.2

Gen II Engine Block
The Ecotec 2.2L starts with a refined engine block, introduced for 2006 with the Ecotec 2.4L VVT (RPO LE5). The Gen II block was developed with data acquired in racing programs and the latest math-based tools. Both the bore walls and bulkheads, or the structural elements that support the crank bearings, have been strengthened, with only a minimal weight increase (approximately 2.5 pounds). The coolant jackets have been expanded, allowing more precise bore roundness and improving the block’s ability to dissipate heat. Coolant capacity increases approximately .5 liter.

The cylinder block is the engine’s foundation, and crucial to its durability, output and smooth operation. For GM, the common Gen II Ecotec block increases assembly efficiency. For the customer, the result is more efficient cooling, more strength to accommodate additional power, as in the new Ecotec 2.0L direct-injection Turbo (RPO LNF) and better noise, vibration and harshness control.
