Depends on what your goals are. Is this a street car?
Air to water is cool, but if this is a daily driver, or just a car you drive around town quite a bit I wouldnt mess with it... You can add ice to the water to get it nice and cold for the track or w/e but as soon as you generate enough heat to melt it all and heat up the water it probably wouldnt be as effecient as a big air to air sitting in the airstream up front.

well its not gonna be a daily driver as i can't fit my tools for work in it lol, but i will be driving it quite a bit during the warmer seasons, im looking at one with a larger pump, it really never gets much hotter than 90 degrees here, we'll have a few days where it gets riduclous, i would also prefer an air to air i think though, any other opinions.

Thanks guys.

not pressure on the face of the valve, which is facing the combustion chamber.

I stepped up to a set of Crower springs in my 98 B headed 4v heads with a twin 60mm turbo setup.

So far, so good.

Also, I would stay away from the aftercooler.

It's not efficient enough for my tastes on a car you're going to drive around town.

An air to air is going to give you the lowest average intake temps, I think.

thanks guys, this whole build has been riduclous and i never would have undertook such a thing if i could have forseen the months coming, so many variables have stopped me from already having this thing done i almost feel like im not supposed to be building this car, works picking back up and i'll be busy for atleast the next month so hopefully she'll be running by the end of summer.

Air to water is great if it's a track car and done correctly. None of the kits that you see on most aftercooled vortech cars are done correctly. The tank has to be inside the car and not in the engine bay. If it is in the engine bay and you dump ice in it by the time you stage the ice will be melted and does no good.

But most here are street/strip so air to air is the best setup for the GP here
