Message As some of you may know, I have a '90 burgandy TT, and I'm looking for some guidance on how to proceed with building it, as I am looking to increase power, and naturally the thrill. I've already talked to Tim, SilverTwin(OH) and he has been a huge help, but before I digress, this is what I was looking to find out...

I just purchased the Greddy TD-05 kit from Coz at CZP, and was looking into getting 720cc injectors, Stillen SMIC (so as not to block the air from hitting the radiator), a racing/street clutch, a different type of plenum (not sure what it is called or how it's made, but was told I would need to get something other than what I have), a dual pop charger, and Greg Dupree's testpipes and downpipes.

What I am looking to find out is some guesstimations on RWHP numbers, for one. Also, I realize that the bigger the injector, the more fuel it can deliver. I guess my question is, if bigger is supposedly better, why wouldn't everyone just spring for the 850cc, or something along those lines? Is there an advantage to the 555's or the 720's vs. the 850's?

And also, I realize that this may be a silly question, but with bigger injectors, you are obviously spraying more fuel. But when using the boost controller, that can lower the amount of fuel being sprayed to keep the correct fuel/air ratio, so your gas mileage wouldn't necessarily be rediculous, correct?

So overall, I am looking for some suggestions on the size injector I should be looking at, or at least some guidance into the differences and what they each would do for me, as well as some insight into any parts that I may be missing from the lineup. If you know a system that works and produces high power, but is streetable, please feel free to reply. I don't post much so as not to "waste space on the board" but these were some questions that I had.... Thanks to all that reply.
