hey every1, i did a search, found nothing on comparisons. i got a 3k and i just purchased a complete 4ke injection setup, my 3k has a 2.5" exhaust and extractors, and the bigport head, i was thinking about getting a new cam, and putting the 4ke setup on, but i was thinking why not get a 4k and do the same, with this sort of setup will i see that much more power from the 4k compared to the 3k?
cheers

a bit.. more compression, less than 10% more capacity..
should have more torque. if you have to rebuild the 3K anyway, just get a 4K, 40 or 60thou oversize ACL pistons.. all good.
2.5" seems a bit excessive

heh heh, they look a little bodgy, but at leat the primaries are fairly well matched in length..
the collector doesn't look like 2.5"diameter tho... or is it????
what are pipe outside diameters for primary/secondary/collector?
at least you can cut them pipes off the flange plate and start again
