If you don't have the cash to play with maybe you should do mild port or just stay stock.

I responded in a pm to you, if you plan on keeping the Pettit Ecu and the stock twins anything more than a very minor port is just a waste of time. The stock porting is plenty sufficient for the stock twins, Im not saying there isnt anything to gain, there just isnt much. You are simply asking for idling headaches, likely slight smoke at idle if you keep that ecu.

If you start with stock port use this mesurement. It's perfect, not to big for secondary.

You should port those too. Just get a template.

template is the best idea, and take it to a GOOD machine shop, if you're close to someone who has had their motor ported, just ask them who they took it too, I'm taking mine to omaha (about an hour away) to have mine ported, but I'm going with a larger port.
my mods: 99 spec turbos, efini y-pipe, greddy FMIC, elbow and intake, custom exhaust, 4x850 injectors, and PFC, the guy I told you to PM has the port template I'll be using, and the PFC maps, yay!

its best to practice on a few junk irons before going on with YOUR irons.

you can easily find a 12a or two at the local junk yard... i got 3 of mine for a deal.... $50 each or $150 for one. and they all spun freely, i only needed to turn them with one hand.

I used them for practicing porting to get a feel for how the tool reacts and how close i can get to the line before going with a hand file and beveling the edges.
