randy 77zt Posted June 9, 2006 Share Posted June 9, 2006 from what i have heard if you bore out a l24 rod 1mm on the small end and run a ld28 crank you can use these pistons.i got a free set .the piston has a roughly 9cc dish-i measured it with a syringe and soapy water.what would compression ratio be with p90 head?bore size is 86.5 mm Quote Link to comment Share on other sites More sharing options...
olie05 Posted June 9, 2006 Share Posted June 9, 2006 still need the pin height to calculate everything. Edit: I got a pin height of 31.75mm... is that correct? with that pin height, and ozdats online calculator: 2.927 litres 7.236 static cr with a 1mm head gasket Quote Link to comment Share on other sites More sharing options...
TheNeedForZ Posted June 10, 2006 Share Posted June 10, 2006 I thought VG pistons start at 87mm? With VG30E(I know it's not vg30dett) you get 21mm pin size and 1cc of dish, dunno about ET tho. If boring & honing out six rods cost as much as getting VG30E pistons then they are about the same cost-wise. Just throwing it out there in case you have second thoughts.
