I have a 88 vert N/A and just got done porting and polishing the intake. Took only a couple hour for all the porting and polishing. The trouble was getting it back togther right. But I finally did.

It is crazy how much it changed the top end power. as I am sure most of you know the power drops off at about 6K rpms on the stock 13b. Not anymore for me. It pulls harder at 7500 than at 6000! I am so glad I did this. All this extra flowing is helped out of course by the lack of cat and a free flowing exhaust. This is a must mod if you have the resources to do it.

 

sounds great

i want to port my car is it really hard to do?

 

I have a port kit. Comes with some cool tools. they arn't a must though. Read through the sticky at the top of this secition. AND MAKE SURE YOU HAVE NEW GASKETS! If you are well versed in wrenching its not tough.
