Twin Turbo REW Cosmo. How much boost?
How much boost can you run on a Twin Turbo 13BREW Cosmo motor stock turbo. Big streetport and front mount intercooler.
Car will have a Haltech F5. Manual boost controller.
Any schematics on the turbo layout etc?
Thanks,

I think you mean twin turbo 13B-RE cosmo motor. 13B-REW = FD3S...not JCSE(or whatever the cosmo body was called).
Boost is dependent on how much fuel you have but don't expect the turbo's to stay alive long if you daily drive 15 psi.

Mazda quoted both engines as a 13B-REW
Simply defined as a JC 13B-REW or FD 13B-REW
As they are basically the same design of turbo, dont exceed 1-bar boost if you want them to remain reliable. 99% of the Japanese tuning shops use 0.9 - 1.0 Bar for any twin turbo engine job. They are simply to fragile to tolerate anything higher & remain reliable.

also IIRC, the cosmo (13B) has different turbos than the FD motor.... FD uses 2x hitachi ht-12's... (and im pretty sure) that the cosmo 13b uses 2x hitachi ht-10's which are tiiiiiny. if i screwed that up can someone correct me? but im pretty sure thats right. oh and for reference... the 20b uses one ht-15 (primary), and one ht-10 as a secondary (too bad they didnt use a 12... but the way they have it configured in stock form i understand their choices for turbo sizes) -heath
