Hey what type of bit do i use on my dremmal??? and can i port the part where my MP TB is connected to the intake manafold??? Or does this have to be done by a machine? thx
97 Rs 5sp -Intake -Front upper strut bar -Tint 20% o yeah -Coilovers/KYB ADJ -60mm TB -P&P intake mani -Cat Back System. -Funny Rims?? dont lie ~likestofloorit.. (1/4=16.258)(60=2.363)

yup, those are what i use, and just dont forget, a little is a lot, don't do a lot in one area at once. gasket match everything so you get the most out of your porting. take the sensors off before you get started. clean it out really well with carb cleaner or something before putting the intake mani/tb back on your car. if you do your exhaust mani, its not quite so critical because its all just going to blow out of your cars ass anyways, but id till clean it out for the most part as well before re-installing. dont do any porting to your engine/block, have that done at a shop. if you ever think your really talented with the porting, you can maybe think about plugging up the holes with some rags and portmatching your exhausts ports on the block to the exhaust mani/gasket. happy porting, enjoy the endless hours of boredom just keep thinking "hp" and wear ear plugs at least sometimes to keep the headaches down.

Everyone says gasket match this, and gasket match that. Gasket companies dont know anything about flow. What they do know is to make that gasket big enough that it wont restrict flow and make the gasket good for sealing.

Don't try to port it to match that MP throttle body unless you take it and have material added around that bottleneck. The exterior diameter of that bottle neck is barely over 60mm and you'll have a big gash (it happened to someoneon this board)

well no you see, obviously youve never gasket matched considering your firmly against it, but honestly there is nothing dramatic about it. it has absolutely nothing to do with using the the gasket as a diagram for perfect flow size/shape. it's simply an easy way of assuring an identical mating surface between the two parts separated by that gasket. which WILL improve flow in these cases.
perhaps you already know the process but just for example what you would do is: take the gasket, line it up perfectly with the bolt holes, trace the gasket holes onto your intake manifold, then take the same gasket, line it up on the throttle body perfectly with the bolt holes like you just did, and trace the hole on there. then, you port it to match the tracing, and be very critical about tightening up everything with the gasket in there the way you need it. boom, now your throttle body and intake manifold have a perfect fit with no restrictions. like i said thats just an example, infact now that i think about it, our stock intake mani's and tb's might match up perfect to begin with. but this definately serves a purpose in at least some applications.
just keep thinking "hp" and wear ear plugs at least sometimes to keep the headaches down.
