a few questions about the intake mani and etc.

I was wondering if I could take a die grinder or something like a dremmel to the intake manifold, exhaust manifold and throttle body to open up alittle more flow or not?

If you do that then you have to port the head as well to gain performance.

I better just leave it to the pros lol

thanks pico , Ill search alittle more lol.

There's a lot to consider when porting.

You might want to focus more on porting the head though since it will be where the gains are... also larger valves. talk to rjudgey

then upgrade to a after market intake manifold from B16 or B18c5 and port match that
Also don't bother porting the stock exhaust manifold, though you can, just grab a header.

Also if you port the exhaust manifold make the ports on the manifold larger than the ports on the head to create a small step for some added resistance to back flow.
However it's really more for those with a cam that's prone to reversion. Remember not to smooth the transition by chamfering/beveling because that will aid in back flow.
Too large a step will lead to separated flow and drag on the exhaust gas.

if you don't want to go too far,take your head,paint the area where the bolts are with dykem blue, now slip the intake manifold gasket,or exaust manifold gasket over the studs, and mark around it with a sharp object such as a scratch awl. you'll see there is metal that is inside of the gasket area. this is what you want to carefully remove. this will help considerably as far as flow.you need to do this to the head side,and the manifold side. one mistake a lot of people make, they polish the intake manifold side, you don't want a mirror finish on the intake side. use some 180 grit sandpaper to rough up the surface when you are done,talking about inside the ports. a mirror finish on the intake side will cause fuel to come out of suspension and condense on the surface. now on the exaust side,you want a mirror finish,the reason for this,a mirror finish reflects heat back into the manifold and back into the exaust stream. more heat reflected,less heat absorbed by the manifold.

thanks guys!

yeah send the head to the machine shop so they can do a port and polish job on it. also the b16 or b18c intake manifold
