Re: TBI porting
You won't need more fuel than stock for now. Clean injectors and if necessary, new fuel pump. I just ran a bottle of injector cleaner through my '92 and picked another MPG. Now I'm at 23 MPG. This IS a 17 year-old vehicle. I'm still on my original fuel pump.
Please read the FAQ, the Stickies at the top of the forum. I had NONE of the answers to ANY questions. It's ALL been asked and before and stored away.

Re: TBI porting
Yep if stock the fuel is probably fine. When you upgrade heads and cam you will need more. I added headers and LT4 cam without much tuning. [Not that it did not need it a little ]
