Need some advice

just do it all at once. easier. Why dont you want to keep the sohc? How many miles on the motor?

it has 176k on the motor.
Well, i wanted more torque and higher HP and i would rebuild whether i had a DOHC or SOHC.

ok. your probably not going to feel much of a difference in the dohc over the sohc. i got a sohc i wouldn't mind building that up a little bit.

Agreed ^. Your not going to gain shit going form a SOHC to a DOHC but an emptier wallet and more time sitting in the garage. Parts for the DOHC are more expensive than the SOHC (cams = $500+ for a DOHC, $175 for a SOHC) and your gaining a measly +15hp assuming the DOHC you just installed is in perfect condition.
Honestly I would keep the SOHC or rebuild it. The only difference is the ability to adjust cam lobe separation angle (if you even know what that is.....) and a slightly better aftermarket at a much higher price.

alright thanks, but does the ka-e have good aftermarket support also ? Everywhere i look its always the dohc . Im pretty sure there is. Im just not looking at the right places. Thanks though guys.
