Hi!

What's the new compression on the NA mkiv with a 2mm HG, and how much boost can I run? Ca. rwhp on this boost?

I'm pretty blanc, so please help me!

Thanks

2mm gets to about 9.2:1 compression, good for about .8 BAR
3mm gets to about 8.8:1 compression, good for about 1.0 BAR

These are RWHP pump fuel numbers.

Thanks

I think hes talking about NA-T or IS300 using the GE headgasket.. it depends on the thickness of course.

Thats what I meant.. i.e. 2jz-gte headgest on a 2JZ-GE engine resulting in 9:1 compression.
