Exhaust upgrades are soon coming, and I am teetering towards 1 5/8 long tubes or shorties to replace my crusty stock headers and H pipe.
I was planning a 110 or 155 LPH pump to replace the old stock unit. The injectors are pretty good now, but I figure they are pretty old, and the price for a new set is not a killer.
Will I end up with problems running the 24# injectors?? I figure I will need an adjustable FPR along with the new pump.

Since it sounds like your staying close to stock, don't get a 70mm TB, stick with a 65mm. A 70 will actually hurt you unless your going forced induction or head towards a big HP application. As far as the 24lb injectors, if you get them you will definately need an adjustable regulator cause it's going to run rich without it. I don't see any problems with you running them, but I bet if you asked someones got a set of low mileage 19's you could probably get for next to nothing.
