13b-re questions
Ive searched here and google and gotten no clear or undisputed answers if any at all..I have some real basic trivial questions about the 13b-re.
1) how much hp does it make stock and at what boost?
2) what size are the stock injectors and how much boost/hp can they support.
3)ive seen several people mention the stock fc radiator not being enough for the RE is this true or BS?
I have more but as usual i forgot them as soon as I started to type this thread.

Also, on a 13b-re with a s5 turbo will a stock s5 exhaust match up?

^^^^I didnt literally means tock exhaust, i have a RB downpipe and aHKS midpipe and cat-back. I bought it for my N/a turbo project but i sold that and am currently buying a fc with a 13b-re swap. So i need to know if it was still useful.
Sorry for the turbo confusion I know what I mean it just came out wrong. I was trying to ask, at what level of boost would you usually upgrade the secondaries? Im -planning on running around 12-14 psi, do you think the stock 550's will work or should i upgrade to 720's. ALso will fc top fed injectors fit the secondaries and FD side feds the primaries?

Im confused now, another site states that the 13b-re shares the same injector sizes with the s6 which is 550's & 850's. Im sorry for all the dumb questions im just tryign to learn what i have.
I searched for a whole day and turned up squat before i decided to post(assuming i would be flamed)

CR is 9.0:1, same as all post-89 Turbo rotors. Stock max boost is 11psi like I said, which isn't all that high.
The info's from www.dmrh.com.au. This guy knows JC Cosmos better than anyone outside Japan.

^^ thanks man, looks like a pretty informative site. I searched here and google for days and couldnt find any real helpful 2-rotor cosmo info. Im gonna go read through it all now
Im still a bit confused about the psi thing but maybe its just my lack of turbo knowledge/over expectations.
If the s5 TII makes 200 hp at 7.5 psi I woudl thing the re with the larger port/runners ect would make a bit more than 230 hp at 10-11 psi.
