Block rebore issue

malaysia_boy · Aug 27th, 2003, 03:28 AM

let's say, if we rebore the engine block, 2mm bigger.

can the original gasket be used back? or we need to alter the gasket for the enlarged bore?

unless you want the gasket to be resting essentially inside the combustion chamber, you'll need to alter it or get one with a larger bore. You could get a machine shop to cut you one out of copper

the block is the same from what i remember between the two displacments. im preety sure the displacment is altered by other means. so if im correct then the pistons should be the same also. am i? i jsut remeber someone sayin that a while bak. havent really got aroudn to tearin these e-series down and seein how they tick.

the head gasket is ok for .040 oversize...still 2mm is standart rebore (2nd actually)

It's safe to go that much? That's .080, a lot more than I would have considered.

1mm = .020 ... some people goes to .080 but that way over standart rebore .... 2nd rebore is .040 (2mm)

Crazy, check your math. 1mm is approximately .04, 2mm is .08. I promise

E15 and E16 have the same bore (76 mm, IIRC), sorry. for large overbores (<1mm) you can get the NISMO head gasket... 77.3mm... i believe the stock gasket is good for .3mm (.010") overbore, but i'm not positive. otherwise, i can get you a brand new block... but you'll have to pay shipping.
