I plan to dual cam head swap it later. That way I get the best of both worlds.JDM_albert wrote:It's nice to see the build moving again.
I usually see people pulling single cam KA's to trash them...
I didn't know the KA had a variable intake system. is it the Nissan version of tvis?FlatBlackIan wrote:Then I will strip the secondary butterflies out of the intake, and clean and reinstall it.
I think it is similar to tvis, though it does not use multiple intake runners like toyota does. There are just butterflies in every runner right before the head flange. They are activated together by a vacuum diaphragm on the back of the manifold. All S13 KAs have them, but S14s do not. I would assume, that like tvis, the butterflies are used to shift the torque curve while lowering emissions.
I picked up a new water pump and thermostat today, and hopefully I can get the engine all buttoned up, and maybe even installed in the car.
