RE: OST-050 - a VERY special build
from another forum Wrote:Are those stock rods with press-fit 18mm wrist pins? I can't remember if those 10:1 pistons had 18mm or 20mm pins.The 10:1 pistons were available in BOTH 18mm, and 20mm wrist pins........ These are 18mm wrist pins... oldeskewltoy Wrote:These are 18mm wrist pins... and a bit lighter too  ![[Image: AEU86 AE86 - RE: OST-050 - a VERY special build]](http://ost.ebeans.ch/albums/userpics/10005/wrist_pin_comparison_2_panel_w_arrows.jpg "AEU86 AE86 - RE: OST-050 - a VERY special build") I decided along with the new 10:1 pistons, that the light weight wrist pins will work nicely in this engine. The 23+ gram (nearly an ounce) saving will help allow the engine to accelerate/decelerate quicker, as well as lower the stress on the rod. btw.....not sure anyone picked out the older design head gasket......... That type (from Toyota) hasn't been around in quite a while... more to come......
