Spencer[RL] Posted May 28, 2011 Report Share Posted May 28, 2011 What size gaskets are used in the calculations? Quote Link to comment Share on other sites More sharing options...
Mitch-12 Posted May 28, 2011 Report Share Posted May 28, 2011 45thou thick and a bit bigger than bore size and are done on standard bore there are some factors that will make it different but it is within .25 of the amount of comp Quote Link to comment Share on other sites More sharing options...
Spencer[RL] Posted May 28, 2011 Report Share Posted May 28, 2011 (edited) For all you boost junkies! A 5k block with d-shaped pistons and a 4k-c head with 8 psi of boost will give you around 10.6 Hmmmmm :laff: Edited May 28, 2011 by Spencer Quote Link to comment Share on other sites More sharing options...

kickn5k Posted May 29, 2011 Report Share Posted May 29, 2011 +1 I got mine with a 4 speed for $150 off Sloth, just from asking around. Speaking of that, when I put in my 5K-ZE setup in a couple of weeks, can I enter this K challenge? :D The setup will be in a Ke55 That's a cheap 5k Ben. Be interesting to see how a blown 5k would go in a 55. I know how they are in a 1x well from the drivers seat of one I never got a chance to race my setup.(damn). Well now I got a r31 LSD and on the hunt for a kr42 "w" series box and it will then cop anti-lag launches!!! Forgot to pick up 4age main bolts from mate yesterday when I put together his forged 4agte short. If anyone wants a quick leg up into a forced "k" Ke-1x I know of one that could be pried off the owner at a reasonable price. Stu. Quote Link to comment Share on other sites More sharing options...
