Are they interchangeable. I was under the impression they were, and bought a 2.2 block, but if they aren't im going to take it back. Just the short block, i know the pistons and things are different but all thats being swapped out.

 

the short block includes pistons...?
they use different crank wheels, different cranks, different rods/pistons, and have a different casting, since the LSJ has piston oil squirter jets cast in. Im sure theres more

 

okay but im taking the crank pistons rods everything out. Can i take and build it with lsj parts and put an lsj head on it?

 

yes if you have deep pockets

 

are you asking if they literally bolt up? I'm *pretty* sure.

 

thank you, this is what i thought, and will be happening.

 

essentially they are the same, but there are many differences.

Even if you stuff an LSJ crank/rods/pistons into a 2.2 block, you won't have the oil cooler like the LSJ has. The LSJ head will bolt onto the block, make sure you use the right crank sensor for the right crank. If you use the LSJ crank, then get an LSJ crank sensor. If you use the 2.2 crank, then get the 2.2 sensor as the counters are different.

Whatever you use, I would go ahead and sleeve the block. That's cheap insurance in the long run.

 

yeah i know i need to replace the crank sensor, i plan on using a LSJ crank. Do i even need the oil squirters? It will be sleeved, heres my parts list.

Stock crank (as long as its usable)
Darton Sleeves
Diamond forged pistons ups the compression to 10:1 or 10.5:1 (suggestions please)
Carillo H beam rods
Another stock head that will be P&P
Neutral Balance shafts
Rings
Supertech valves
ARP Studs
Supertech 78 lbs valve springs
Exeedy Hyper single clutch
JBP Cams

 

I'm not 100% positive, but I think the 2.2 also has oil squirters.

what the hell did you do to your stock engine?

 

Hmmm...sub'd cause our cars are twins and im hoping when you go tvs you give your twin some good deals on your old parts

 

High Dollar Build... Good Luck!

Question though.. if you're dropping all that cash (Carrillo Rods especially).. Why not start with the right block?

 

i wouldent use jbp for **** even if it was free

 

As far as using the LSJ crank/rods/pistons.. didnt see it mentioned, make sure the cylinders for the 2.2 block match the 2.0 block. I dont know the dimensions but something I would personally check.. But with the stroke difference, you want to make sure that the pistons arent pulled too far down. when at the bottom of the stroke. Also wanna make sure that TDC is correct in correspondence to the deck height. They may be identical in this case, with the internals removed, but always good to check..

 

theyre identical across all blocks except the 2.4l blocks, which use a larger bore (2mm larger)

 

Absolutely nothing, its whats gonna happen to my engine when the stuff in my sig goes in and im making over 400 whp.

Thanks, I cant find the right block around me, and i found this 2.2 thats in perfect condition with crank and everything i can sell out of it for just 150.

Ill remember that.

alright will do.

 

2.2 blocks dont have oil coolers OR piston cooling jets.

 

do i need these?

 

need? no. do you want them? yes

 

Yes you definitely want them. The 2.2 is the only engine that doesnt have the squirters....that should tell you something.

As far as the oil cooler goes? thats actually debateable, the biggest issue is youd have to delete all the cooling hoses for it, not really a big deal, but just something youd have to do.

An LE5 block would be a better choice, they are cheap too, have piston jets, early ones have the cooler,and then youd have a 2.1L

 

2.1L could be a fun motor.

 

hmm, what kind of cars did they come out of, ill look into them. Would they use the same pistons and hardware as the 2.0s?

 

2.2 block lacking the oil cooler isnt a big deal because you can always hook up an external one if you want one... the piston oil squirters are certainly a good thing to have though. People do build 2.2s and other motors that dont have these, so no, its not the end of the world. However, if you started with the 2.0 block, I personally wouldn't want to "downgrade" and lose some of the benefits it has to offer.

 

2.4s? thy came in all sorts of **** Ion, Cobalt, G5, Malibu, G6, Soslstice, Sky.......

You would need custom pistons. The 2.4 has a larger bore.

 

I think he was asking about a 2.1 which was mentioned..

 

A 2.1 is what you get if you stick an LSJ crank into an LE5 block.
