HTA green or red... i cant decide!!
If you are like me which fast spool is absolutely imperative I would choose the HTA green over the red. There is an exception to that(only my opinion), that would be if you have a larger displacement Evo.
If someone ever offere a turbo with varioable geometry blades that would be your choice, unfortunately there is not such thing for Evos but there are for Porsche and VW in Europe.
Again, my suggestions would be HTA green by a long shot. I would also suggest getting it ported and get your manifold ported, IC pipes and a high flow air filter with a good air pipe intake(Perrin).

Perrin is overpriced garbage imo. Im willing to bed that the red only spools a few hundred rpm slower than the green so i thing the red is going to be my choice
im not running stock manfold and i have aem so no maf
what maifold are you running tim?? You need to see my custom one that just got finished. as you stated you went with the top dog like me the fp black. Carlos you do realize the fp red is not to much slower in spool then the green. but i understand if you want in the powerband as fast as possible with decient top end.

yea for sure man id love to hear the results, and yes i think perrin isnt that great and very over priced. maybe for a stock evo i guess it would be ok
rockman lets see it

The Perrin intake is garbage, IMO. I have seen too many people with gunk in their pipes or the filter just cracking on them from the heat underneath the hood. It does a terrible job in filtering out small particulates from the intake air. Less filtration means more crap makes its way into your turbo and eventually your cylinders.
FP does offer indeed a intake pipe for the FP Red, Green and Black but it is made of silicone. Also the outer diameter is now 80-84mm so 4" would be a 100mm (too big).
I just ordered today a HTA GREEN and I had absolutely no need to get a bigger cover port. There is a lot of literature about bigger port =lesser surging but I know of a tuner that had difficulties already tunning a HTA Green with a bigger port cover and a specific intake pipe causing surging.

Why the 24psi on 91oct quote/remark though?
