Mission to mid 300s low 400s rwhp

Hey guys. I am fairly new to rx7s or cars in general for that matter and would like to learn more. I have a 1988 TII with rats nest/emissions removal, s5 turbo with a ported WG, FMIC, 3" TID, greddy PE exhaust with RB down/mid pipes, ACT HD pressure plate, and lightweight fly wheel. Its a virgin 13b block, never been opened up. That also goes for the ems as well. With that being said, I am looking for a set up that will get me mid 300s, low 400s to the ground. I would hope for mid to low 12s on the 1/4 mile as well but at the same time be able to street it. I hope its not too much to ask for but, I really only have the slightest idea as I already mentioned I am a total beginner to all of this. I was told upgrading to rtek 1.8 with a bnr stage 3 can get me close to those numbers. I just want a cheap but efficient way to get to my goal. I am still in school so take it easy on me guys. Hopefully some rotary elders can find the time to hook me up with a good ballpark set up or "spit some knowledge" so I can have something to look into. Thanks in advance guys.

cheapest way for you to go is BNR stage 4 with 720/1000 cc injectors, Rtek 2.1 . The Greddy PE exhaust I had was 2.5", you will want 3" . That will get you mid 300's on stock ports. It is my understanding that say 330-350rwhp is the limit of the stock airflow meter, or at least I've never seen anything higher than that. Once you get over mid 300's costs go up and up and up: ignition, turbo, manifold, fuel system, engine management, porting... each additional hp costs more and more time and money.

for your info, my stock block hit 340rwhp with a 60-1 turbo.
I wouldnt bother porting for lowish HP's. It does have it upside for spool etc, but when on a budget its not critical.

Havoc would you mind sharing how your set up looks like.? Also, If you have the information; what did you run in the quarter mile? The link in your sig doesn't work.
