2ltr bottom end
« on: 06 August 2009, 11:13 »
Alrite people  :smiley:
Ive just had this idea of maybe changing the bottom end on my valver for a mk3 2ltr and using my 16v head with Kr cams i should see around 180bhp? (including the four branch thats on it) my question is, does it have to be the bottom end from a 16v mk3 or could i use the 8v bottom end? are they the same?, as the 8v's are alot easier to get hold of.
Any help, views and suggestion pls.

really would advise against useing the ABF, KR  combo on K JET

the ABF has better cams than the KR,  people rave about the KR inlet cam it has a bit more duration than the ABF cam but the ABF cam has a lot more lift.

the compression ratio is also a bit high for a daily driver,   ABF is soposedly 10.5 :1 cr std  and the kr head is soposed to have a slightly smaller chamber acording to some sorces so if anything the CR is going to go up.  you will be close to the limutes of the k jets fueling and have no knock control.   if the warm up reg malfunctions  it will cost you an enigne if it goes un noticed and isn't replaced
