hp estimations...???
ok i have a 1987 t2 and this is what im gonna do to it so if some peeps could add some idea along the way or if i missed something plz tell me, also if some one could give me a rought hp estimate.
1)s4 13b t2 with stage 3 street port/ all emmissions removed and ported and polished TB.
2) hks t04s with hks manifold
3)greddy FMIC
4) 6 puck un sprung clutch
5) haltech (not sure which one to go with the ek6 or e11)
and all the rest of the little mods that must be done to support theses things, injectors, oil passge mod on the e-shaft with the holly jets, thermal pellet mod, radiator and so on.
i am also debating running 2 NOS foggers in the LIM for a total of a 70 shot just for a little faster spool, but not sure on that yet.
any suggestions or stuff i missed??

If you have to ask if thats an ok "plan" and your trying to guess HP then you probably shouldn't start doing that serious of mods yet. untill you know exactly how everything works don't mess with it, you'll end up spending way to much money and time fixing the stuff you break because of lack of knowledge.

I dont think you really know as much as you think you do. You didnt even tell us what turbo you have. All you did was give a compressor housing. No A/R, no trim, nothing. Yeah...You sure know a lot about what youre getting into.
Hell, I bet I at least know more about a keyboard than you.

Slow down there man. Geeze, you can't come on here and ask a question... and then start spouting off about how you know more about this and that than other people when they say something you may not like. You will get ZERO help that way.
With that out of the way here's my $.02:
First you need to tell us what you want to do with the car. Daily driven track only? Auto x, Drag, drift... what?
I have no idea what a "stage 3" street port is... I'll assume you mean a "large" street port. That can be good, and I have a large street port, but the shape and port timing make all the difference in the world. Simply putting a big hole in the side plate won't do anything and could hurt power if not done correctly.
A T04S is a generally a good turbo for the street and is *capable* of making 400RWHP. This is TOTALLY dependant on all the other modifications being present to support that sort of power. Why get an HKS turbo though? Just get a turbonetics 60-1 and save some money by not having the HKS name. To some people that's worth it though, just don't expect that an "HKS" 60-1 is any different than a "turbonetics" or "garrett" 60-1.
WHAT?! dude, what are you talking about.. I take this comment as complete and totally ignorance. That's not bad, just means you don't know what you are talking about. There is no "best" A/R for a rotary. I have a .84 AR and made almost 470 RWHP with it and with a few minor problems fixed this car will make over 500RWHp no problem. I have 20psi boost by 3900 RPM and this is with a turbo larger than a T66 and you're saying that's not up to par?? People run anwhere from a .84-1.32 A/R housing on rotaries, it depends on what you want to do with the car.
The haltech E6k is usually plenty sufficient for yoru setup. The E11 is still somewhat in a trouble shooting stage IMO.
Anyway, you need to do some research before you get to far into this project. You need proper selection of injectors, FPR, fuel pump, fuel lines, ignition, who's porting the engine, what do you want to do for corner seals, side seals, rotors. etc, etc.
The Greddy FMIC is a good choice but will need modified piping to fit the turbo.
I would strongly suggest looking into the clutch offered from Pineappleracing.com They have a new 6puck sprung hub clutch that grips like a copper and wears like and organic, so you won't destroy your flywheel and it *can* be slipped for street driving. Unsprung is just plain harsh, then get an ACT Extreme PP or something like that.
Good luck with your build, but please do some more research before you start buying. Know gear ratios does not mean you can properly design and build a hi HP rotary. It's not as simple as slapping on a big turbo.
