Hey guys. I never build 2.2L and I want to build one now. What pistons/rods/crank are you guys using to make 2.2L out of 4g63 block? I have brand new pistons that were originally purchased to make 2.3L ( 608010C) , can those pistons be used to make 2.2L? Thanks!

 

Anyone can help?

 

I found this thread very informative:

Good luck!

 

Thank you so much it is very informative, I just still can't find what pistons do I use to make it 2.2L , I have some 2.3L pistons and not sure if I can use them. Thanks a lot!

 

This thread is similar. I used it to determine the required piston wrist pin height during my build. From initial glance, it doesn't look like we can use 2.3l pistons on any version of the 2.2l.

Go for long rod if you can!

 

I apologize if this is wrong, but it's my understanding that the piston size does not impact whether its a 2.3L or a 2.2L just the crank size which you need a 94mm crank. If you plan on using a 86mm piston, you will have to re-bore the 2.0L block (to go from 85mm to 86mm) and find an appropriate rod for the 2.2L application. Again I do not have any personal experience with this and a very limited knowledge base. Sorry.

 

Piston bore stays the same but the compression height (wrist pin location) has to change with the stroke, or the 2.3-spec pistons will stick out over the block on the 156/94mm combination combination, or too far under the block with 2.2-spec pistons on the 150/100mm combination. Pistons are application-specific for that reason.

 

Yes, you are correct. But wouldn't the OP just use a 94mm crank on his 2.0L block and adjust the rod length instead of changing the wrist pin location, which can get complex?

Maybe I'm looking at this wrong, but the OP has a stock 4G63 2.0L block and a set of 86mm pistons that he wants to use in a 2.2L stroker motor set up. Wouldn't boring the 2.0L block from 85mm to 86mm accommodate the piston he already has, while using a 94mm crank and the appropriate rod (to eliminate the piston sticking out the block) accomplish his goal?

I'm so confused right now.......

 

So I pulled the details of the piston part number (608010C) from the original post. It is a Manley stroker 86mm piston with the standard pin height of 22mm. Therefore, in theory, all the OP would need is a 150mm rod (standard EVO spec) and a 94mm crank to accomplish a 2.2L build. This combination should yield a piston deck clearance height of -0.35mm. He would also need a 86.5mm head gasket. Is that correct?

 

Your train of thought is not wrong, it could be an alternate solution . The thread I posted above assumes a 4g64 block (larger factory bore size and additional 6mm of deck height.) There are a few ways to assemble the 2.2l, but the big question becomes what will fetch the best rod/crank ratio vs which parts are standard off the shelf (cheaper) vs custom order. The OP has a few options. Some people use the OEM 4g64 eclipse head gasket since it already has the right bore size. (Mitsu part MD332035)

 

Thank you so much!! Yes those pistons were originally purchase to build 2.3L stroker with 4g63 block with 100mm crank and 150mm rods. The plan has changed and I want to use those pistons only and upgrade wrist pins to make 2.2L if possible. So to do that will I need 94mm crank and 150mm rods? Yes they are 86mm because block was bored to this size.

 

That's my understanding. But please confirm with an engine builder as my knowledge is theoretical and I have no first-hand experience with a 2.2L build. BTW, Pal215 did bring up some good points (about rod/stroke ratio and cost) that have been heavily discussed on this forum. If you do a quick search you should be able to easily find those posts. Good luck!

 

The problem is I am the engine builder but it is my first time doing 2.2L. To my understanding if those pistons were purchased to use with 100mm crank and 150mm rods I think I need 94mm crank and 153mm rods to achieve 2.2L but I might be wrong here. Everywhere I search look like those pistons are only to make 2.3L so I am kinda lost here.

Also, PM LetsGetThisDone. He's pretty knowledgeable and I read good things about his engine builds.

Good luck!

 

This is what I did with my engine, I opted for the upgraded wrist pins and they honed my bores to 87mm for clean up. Then opted for Callies crank, Manly turbo tuff rods and Manly pro pistons.
