Intake porting on a turbo charged engine...Questions

I tore apart my intake to clean it all up and had been thinking about porting it while it is off the engine. I have never ported an intake before and have a few questions.

 

1. Being a turbo engine...would a mild port job be of any real benifit? I am upgrading the turbo and will be running a 3" DP.

 

2. I can see where the old gasket ended and where the extra metal is...should I buy a new gasket first, to make sure, it fits the same way?

 

3. Do I need to tapper it back into the intake? Start out getting all the extra metal up front, and then just tapper it back, as far as, I can go?

 

4. With the bits I bought, I can only go in about 3 maybe 4 inches...is this enough?

 

Any other tips or thoughts to add to this?

 

Thanks,

Jason

One more thing, at the very top of the intake port opening, where the fuel flows in from the injectors, is it ok to grind some of that away. It won't mess up the fuel spray patteren or something? Just wondering.

I have the old How to modify your Nissan/Datsun engine, and it has a section on head porting. I'm in Pittsburg, KS have you ever taken your car out to MOKAN? What color is your car? I'm in Joplin all the time, maybe we can meet up sometime.
