Jus wondering what specific Rods and Pistons are needed to build a 2.1L de-stroker. I allready no you use the 2.4l block with a 2.0L crank but what specs must the pistons and rods have?

162mm rods would be best. a few companies make off the shelf pistons i believe.

call buschur or awd....... case closed...

Read the title dumbass.

well played sir...

Ive been searching for the 162mm rods all i have found is 156mm. Any one no where i can get them from?

epic win

manley turbo tuffs.

its the 4g64 block (2.4l) with a 88mm crank and stock length rods. At least thats one way to do it.

first off get off my di#%... second i was sugestioning provin stuff instead Of wasting money and risking the chance Of trial and error.....

88mm stroke crankshaft
162mm Manley Turbo Tuff Rods
86.5mm pistons with a dish volume of -12cc's & compression height of 28.7mm.
with a 1.4mm thk head gasket, this will yield a static compression ratio of ~8.96:1

How can you reach a static compression ratio of 10.5?

With 87mm bores and a .051" thick Cometic Phusion Head Gasket you would need pistons with a dish volume of approximately -2.6cc's to achieve 10.5:1.
Assuming a 1.130" compression height, .012" deck clearance and 43cc combustion chambers.

If you can find a thinner head gasket that is MLS and 87mm bores, then the piston dish volume requirement of -2.6cc's can go up.

For example with everything the same and you find a .039" HG or 1mm, your piston dish volume requirement to achieve 10.5:1 can go up to -4.4cc's.

If your engine builder is willing to resleeve your 4G64 back down to 85.5mm bores, then you can run any Evo Head Gasket and have much lighter pistons that could routinely get flogged up to 11k rpm no problem!

I was just wondering if its possible to run a 4G69 block with 4G63 crank and rods . If the std 69 bore is 86.5mm I work the capacity out to be 1.5cc short of 2070 .
