finally a real mod [IMG]i/expressions/face-icon-small-smile.gif[/IMG] theoretically you should get more power since ur freeing up that manifold. i dunno if you'll instantly see the results. maybe if u had a dyno that would help. keep us posted if u get it done

what about running lean...any thing to worry about there? I was thinking about port and polishing everything i can! =)

Reset ecu after mode, should take care of the running lean prob.

How much does a port and polish typically cost for a car like ours?

make sure the person that does it for you has a flow bench.

The typical home port and polish job consists of Gasket matching this is when you make the openings of the intake and head match the size of the gasket hole...other than that you may want to clean up any casting marks and radius the short side of the intake runners...when polishing dont use any finer than a 80grit sand paper or the ports will become too smooth and the air will become too turbulant in the intake and head....other than that when doing the Exhaust ports on the head only raise the port roofs or you will loose power in this area, but gasket matching is still fine here.....getting the head ported properly with a rebuild and larger valves, and bowl work will probably run you around $1500, and having the intake extrude Honed will probably run around $500...and net you around 15hp...but this is the way to go if you plan to add forced induction.....Remember more air in and more air out = more HP....but you cant have any bottlenecks anywhere....but if you are mechanicly inclined the home port job is good for about 2-5HP

I thaught our intakes were plastic? I didnt think you could port plastic[IMG]i/expressions/face-icon-small-confused.gif[/IMG]

I was wondering about that myself...

i believe he was referring to the intake manifold, not the actually airbox.

Dakker · 01-18-2002

hehehe, yeah you will feel gains if you do this, about the same as adding an aem intake

<< i believe he was referring to the intake manifold, not the actually airbox. >>

Yes, which would be plastic.....

Porting ur exhaust manifold is a better mod than your intake manifold........

2k1EXracer · 01-19-2002

you cant port either our intake or exhaust manifolds.

our intake manifolds are plastic and our exhaust manifolds are tubular steel. you only port things that are thick cast metal.sorry![IMG]i/expressions/moon.gif[/IMG]

Dakker.

Would you mind removing that cartoon? I've seen it on more than one thread and it causes a delay when loadiing the page.
