Cams for FD?

787b ftmfw and idk if you were serious but bridgeport or periport for the sound but the 787b is the swap you should do. 4 rotor n/a and makes i think wat was 900hp
 
I think forged pistons are the best way to go.:bigthumbu

I think RB26 pistons fit the 13B block but u need to sleeve it.


Bwuuuahahahahaha!

787B isnt exactly a swap....... lol The motor is a R26B and Mazda only made a handful of factory ones, and then supported a few private outfits running them, like Jim Downing up in ATL and Courage recently ran one at LeMans. These days you have to build your own (lots of time, money and machining) or find one from a race team, ($25,000 or better usually).

Also they made more like 700hp at around 10,000rpm. Just like a NA PP 13B will make roughly 350hp at 9-10k rpm. If you want more than about 10,500rpm then you need specially heat treated and hardened stationaries and you can start teasing with 13,000


But yea, for that sound, forget PP, just get some fat cams, like 320* duration with TONS of lift. You can add PP later but it will just be ridiculous then.... lol

Yea well the 13B has a funny cylinder shape from Mazda, they did it for some special reason, so if you want to run aftermarket pistons you always have to sleeve it....

You have to be careful with the big cams in the 13B you need to upgrade your springs and retainers so that you can safeguard against valve float.
 
Hmm. Idk, I'm thinking of roller rockers and some beefy springs but still can't find a good cam.
 
the valvetrain on a rotary is THE MOST IMPORTANT THANG NOT TO FORGET mazda almost always forgot with the rotaries





























:D
 
Yea I know man. Wheres the kid who said he knows someone who can make them? I'll pay up to $1500 for some good cams.
