Evolution Auto Performance : Project Horny Restart :)

Maybe it's cheap because it was possibly done with an "eyecrometer" and not flow tested for balanced flow across all ports...

regardless. i paid close to the same for my machining with no port whats so ever. not going to get into it but the "benefits" from porting are still questionable. for a true bench tested port and polish you should be looking at ~3k

that labor is CHEAP especially for the port.

mind me asking how much was the machining for the head? including the 5 angle valve grind and the port?

$1600 for labor
$1500 for parts
$1000 for the cams

glad there is a comeback.
I also used a N1 to break in my motor. Guess I was lucky.
all tho I never pushed it beyond 7k while breaking in the motor at the dyno.
Now i sold my jun pump and kept the N1 rev limit is at 9k
with a reimax oil gear kit.
wouldn't do it on a rb25 with out solid lifters tho....

Wow....back from the dead is right. Can't wait to see what she can put out with someone who actually knows how to use a micrometer and a brain. Where did the Trust/Grex dogbox come from, had it all along or did you grab that one from West Coast Hotrods? I wish I had the time to work on stuff, my new fuel system might actually get done.

Keep the updates comin'.....
