[u:98f2b5eeb5]16V[/u:98f2b5eeb5]
US 4AGE early 9.4 to 1 euro 4AGE early 10 to 1 1990+ 4AGE 10.3 to 1 stock head gasket is 1.2mm. Each 1/10 of a mm is ABOUT 1/10 of a compression point. using .8mm gasket you get a .4 compression boost. The later 10.3 slugs, and .8mm gasket gives you an approximate CR of 10.7 to 1 Anything much over that will need a stand alone engine management to run at its best. There is an advantage to running 16V high compression slugs... they are cast(with heat coating). They are MUCH lighter then the 20V pistons which are forged Woper - from my info each piston has different rings... 20V rings are pretty much for 20V pistons. Dan - You can |  .... OR you can ask for help!!!OST Porting service - http://hachiroku.net/forums/showthread.php?t=19991 |
