I have a 92 accord and i wanna know how to port match the intake manifold. i know it has somthing to do with lining up the gasket. What exactly do i do? THANKS

Put the gasket on the intake manifold, get some bolts and nuts so you can keep the gasket from moving around. Then carefully take material away gradually until the ports on the intake manifold match up to the gasket. Your going to have to use porting scrolls that are basically sand paper bits for a dremel tool. Sand stones and metal bits have a tendency to clog. Good luck.

Doesn't help much though unless you port match the intake ports on the head in the same fashion as well.

That's the "port matching" part. You're not port matching if you only do one side.

Exactly. The original poster was appearantly only planning on doing the manifold.

Theres also a special machinist technique of bluing then scribing to port motch both the head and the mani. to the gasket size. If You have no acces to such technique Just place the gasket and bolt it or tape it in. Then Scribe it (with a sribe lol) Around the ports Untill its matched with your gasket. You can then use a dremel (as stated before) to CAREFULLY remove the material.
Try not to change the shape of the port or get to ambitous and take away to much material because this can either make you port job ineffective or Even lose power.
