2.2 crank for 2.4?

[glhs875]

Does anyone offer a 2.2 (3.62 stroke or similar) for a 2.4 engine? I know one is offered for the 2.0 engine.

:confused: I'm confused
aren't the 2.0 and 2.4 's pretty much the same thing like our 2.2/2.5 common block
different crank and pistons?
so you should be able to use the 2.0's 2.2 crank in a 2.4 correct?
I'm a nebwie at this modern stuff so don't take my word for it

Nope, the 2.0L is a different block... the early 2.4L and 2.0L heads are almost identical tho.

2.4L has a longer nose on the end of the crank, larger main bearings, and larger rod bearings. These reasons are why the 2.0 and 2.4 will not interchange. However, the 2.2 and 2.4L have the same rear seal diameter, rod bearing diameter, and main bearing diameter. The nose of the crank is very different. The 2.4L drives the oil pump off the crank and the 2.2 does not.

I've looked at this and mocked it up, but the cost to modify the block/crank was better spent on a killer cylinder head in my case.

I wish! The 2.0 has a different block (shorter deck), rods (shorter), crankshaft (smaller main & rod journals) and different pistons as well. I could use a 2.0 block, but I would rather use the 2.4 block and then have 6.18" rods or maybe even a little longer. If I can't score one I'll just leave it 2.4 for now.

Offset grind the crank to use the same size bearings as the 2.0. You're looking at custom rods anyway. Also, there are tons of cheap used Nascar Carillo rods on eBay that use the same diameter (though, they are all 'skinny' rods). The 2.0 rod pins are 2mm smaller than the 2.4. So, you could get up to 4mm decrease in stroke that way. That gets you down to 2.3L...

I think you may be on to something. I would need a total of .360 in stroke reduction to make a 2.4L into a 2.2L. A 2.0 has a 1.89 rod journal. A 2.4 has a 1.96 which equals a .070 difference in diameter. So your saying if the crank was offset ground .070, that would double and then equal a .140 in stroke reduction? If so that would put the stroke @ 3.84". Or I could go another .010 on the offset which would bring the journal down to 1.88" (Honda size) and then gain another .020 in stroke reduction which would equal 3.82". And yes that would be right at 2.3L.
