That is beautiful. Why is there so much room in the front thought?Did the guy remove the fan and radiator assembly and do something custom? Mmm I love it!

 

looks like they just arent installed yet. my radiator is moved back 2 inches and i have a custom fan, soon to be replaced by a small (LIGHT!) push type fan prabably from a honda. mine is currently a huge fan pull through type setup, good for turbo or whatever setup, but not needed for NA.

hehehe... its getting an electric dual fan set up, to handle the scortching of autocross and time attacks =0)

 

Has anyone noticed that the intake is missing?

 

back to the thread topic. the S13 KA's have a flap in the upper part of the intake manifold near the valves. this are closed at lower RPMs to increase torque, and at higher RPM a valve creates some suction and the valves open fully to increas air flow...

 

now removing these arn't going to give you a noticble power gain.
if you have a s13 ka, i would recomend you just leave it alone unless you plan on trying to eek out any bit of power for competion reasons...

here's another pic.

 

i believe they are strictly vacuum operated, with a stiff return spring for when vacuum gets low and then they open. ? ill be taking mine off soon, while installing the itb's, then i can confirm how they open and also power gained/lost by removing them.
