so i was wondering who made the most HP and what your combo was of parts. like using only stock factory internal parts and stock irons and rotor housings, unlimited intake and exhaust. I was thinking of maybe 6 port end irons with the pineapple racing 6 port inserts, 12a center irons, S5 rotors and turbo two rotor housings. thats what my build is going to be anyways, lets see what you all have.

 

I couldnt tell you what the exact HP would be, IMO Pineapple inserts will probably give you minimal gain, look into porting if you are going for a strong N/A with enough work a good tune I have seen Street ports at 200 HP at the fly wheel

 

You can't use TII rotor housings with a 12A center plate. Not without milling a coolant seal groove in the center plate, anyway, and then it's no longer technically stock internals.

Adrian made 191 WHP from a not-quite-stockport (stock port timing but smoothed runners) 13B that had GSL-SE end plates, a 12A Y casting center plate, S4 NA rotating assembly, and IIRC GSL-SE rotor housings. He used a Weber 48 IDA and no auxiliary port sleeves, with a custom 3" exhaust.

 

If you really want a good combo you have to start with 13B RE Irons (largest stock ports), then move on with the RX8 e shaft, S4 NA rotors with FD Rotor housings. Race clearance the rotors, balance the rotating assembly and that has the makings of a good start. Anything else is pretty much a waste of good parts.

Just my 2 Cents.

 

Why wouldn't you use s5 na rotors?

 

S4 na rotors have stronger apex seal slots

 

this is just an idea, we have like 4 motors torn down in the garage, and i want to get something together to put into our rotory truck.

 

TitaniumTT over at Rotary Car Club is making 400+RWHP and has 250 ft/lbs of torque around 3k. I think he made it out of a 13b-RE with REW twins can't remember what porting he did. You should talk to him he will give you alot of info.

 

the idea was to make as much power as possible without spending ANYTHING on porting

 

Pineapple Large streetport template, sixport inserts fixed position, s5 na block, weber Ida 48, all oem seals. 240hp crank. Super streetable, decent milage, Lots of fun.

 

What benefit were you seeking with the 12A center iron? Just wondering?

 

yeah because what is the point of using the tall runner "Y" plate if you are not going to port it. That is the only advantage of using that 12A center.
