a3 bottom?

[2slowcivic]

how high can I rev a a3 bottom end with a k20z1 head and be some what safe?

[nightrider2002]

8K would be some what safe 8.5k is pushin to the limit. The crank and rods are weak.

i would say 8k should be the limit, and that is with an upgraded valve train. the stock valve train wont take too many passes spinning that fast.

edit: doh....just saw the Z1 head as i hit submit. guess i should read in more detail...lol

The time and cost of swapping heads isnt worth it, unless you change the A3 internals as well IMHO. R&Ring the head is not a quick job. It also will not produce the same whp as a typeS either(lower compression on the A3) and you will need Kpro.

not worth it IMO my buddy did it and was still gettin pulled by new si's all day...
