paulyyy Posted January 6, 2010 Report Posted January 6, 2010 Hey guys I'm sure someone will chew me out for this but I can't find the info any where. Just wanting too know if a 4k head on a 5k will improve it or not? Quote
Evan G Posted January 6, 2010 Report Posted January 6, 2010 (edited) this will increase the compression? why not shave the 5k head? I'm also curious if anyone has put a 4k head on a 3k bottom end? very low compression suitable for some boost? a lazy 10psi? Edited January 6, 2010 by Evan G Quote
paulyyy Posted January 6, 2010 Author Report Posted January 6, 2010 well I have the head off the 4k out of my old 55 and I had the head shaved and cleaned up a bit at the time so figured if it works too my advantage id use it Quote
love ke70 Posted January 6, 2010 Report Posted January 6, 2010 most 5ks have a piston with about 16cc (from memory) dish in them, so you end up with an absolutely shit comp ratio. there are a number of threads about it on here, is it not covered in the faq? Quote
BReNt Posted January 6, 2010 Report Posted January 6, 2010 Bad. Don't do it unless the heads from a dished piston 4k engine. Quote
paulyyy Posted January 6, 2010 Author Report Posted January 6, 2010 ok cheers thanks for the help...guess the head will make a nice paper weight haha Quote
SLO-030 Posted January 6, 2010 Report Posted January 6, 2010 Can you PM me with details of this Shaved and "cleaned up" 4K head please. Quote
