metal hg thickness

[minivan_don]

ok ... im trying to figure out what tickness of metal hg to get for my s2 rb25 and although i have searched here and on hybridz, i have not found any difinitve answers.

what i got? - wiseco 8.4:1 pistons- eagle rb rods

im just gathering some quotes for the machinging i require ... (boring/honing/decking/hot tank block + resurface head) and from searching around i found a 1mm and 1.29mm greddy hg

it depends how much is taken off the block and head. you are going to have to deck it pretty far to get a .2 bump in static compression even with a 1mm gasket

have the machine shop do the measurements on the block and head or get a graduated cylinder and some plexiglass and do it yourself.

i doesnt have to be spot on 8.6-8.8:1 ... if i could a bit higher than 8.4:1 is preferred.

thanks for the recommendation ... thats what i figured in a worst case scenaro but my buddy and i are building a huge order with an online store and i can get the hg at a discount and no shipping so thats why im trying to figure this out now

Well What about Metal H/G With the stock thickness so you don't ahve to shave off of the block? Where can those be bought or are they the same as the 1mm?

[Joe]

IMO you MUST deck the head and block with going to a MHG.

[Darius]

IMO too.

[minivan_don]

both the head and block WILL be machined ... thats is not in debate here ..

enjukuracing.com sell a 1mm greddy metal hg
