G4CS block Destroked! What pistons?!

[sonicnofadz]

I am currently working on a G4CS block removed from a 1991 Hyundai Sonata. To destroke this motor and run with 2.1 liters (and get a better rod to stroke ratio while I'm at it) I wish to run a regular 2.0L 4G63 crank, regular length 4G63 rods, and OEM NON turbo 6-bolt pistons. The non turbo pistons are of a much higher compression and will make up for the crank's shorter stroke and the taller block. Does anyone know what type of compression this will make? 8.5:1?

I have a G4CS also, you will want a 88mm crank, 156mm rods and the wiseco or similar pistons that are made specificaly for the 4G64/G4CS and 4g63 head build to reach the beloved 2.1L "De Stroker". BE CAREFUL no one makes 156mm 6-bolt rods with a 21mm wrist pin, you will have to have custom rods made and i was quoted just over $900!! make sure you get the 22mm wrist pin, but keep in mind the only 156mm rods/6 bolt/ 22mm pin are the manley I-Beams ($700) this is why im selling my G4CS and looking for a 4G64 so I can have more buying options. you will also have clearance problems possibly with the exhaust and oil pan. make sure to buy the 4g64 head gasket with proper bore size and 4g64 timing belt... worth all the BS in the end with a stroker engine revving like a honda s2k

I'm Actually using the oem crank eagle rods.weisco pistons acl bearings 8.8:1 ratio

My build isnt the same as yours. You might have clearance issues but I wont.

The clearance issue would be on my downpipe I believe
