Anybody ever Ported Intake or Throttle body?

[GTR PrYdE]

A company called PPI http://www.paradigmperformance....html does port work on the KA's intake, which seems to be very good work.

I'm sending him my TB soon to see if he can port that as well.

So, does anyone have experience with port work on the Intake or TB?

i smoothed my lower intake. basicly just took a couple flapper wheels to it and smoothed out the casting. and im doing the upper soon. and i polished the throttle body. didnt port it though. i think you can get a q45 throttle body cheaper than having someone port your stock. i have the throttle body on my car now but not the intake manifold. good luck

If you plan to do it with just a Dremel, it's going to be a long and tedious job.

I had to enlarge a Greddy manifold to fit the Tomei throttle body with a Dremel. Took half a day and was very messy.

Isn't the Q45 tb 90mm?

If so that's way overkill, unless you plan on making 800+ on boost, i'm not.

i enlarged mine with a jand drill and then finshed it with a dremel it took me all day but i did the while intake manifold and did the head

Im under the belief that Nissan did a pretty good job as far as designing a daily drivable motor. Once you start messing with porting you can lose intake velocity and low/midrange power.

I would say the best thing you could do to it would be get it extrude honed. Pretty damned expensive unfortunately, but its the ish. Then a gasket match and your set.

I port/gasket matched from intake manifold-to-head. And then smoothed a bit inside the intake manifold using, what I call, a bottle brush hone. Looks like a baby bottle brush on steroids.

Other than that, I left it alone. Didn't even take the throttle body off. I got a ton of pics on here somewhere in a thread I made when I ported my head.

The port thread is nice Eric, I wish I would've done some head work when I had the head off, but it will be again when the motor gets built,

I just saw alot of before and after of the intake manifold and it seems like just in gasket matching there's room for improvement, andwith the polishing, and maybe even ported TB, that'd be great. Hell I might even do before and after dyno's to see if it's worth it.
