I have been wanting to know for a while what the max boost limit would be for a stock 13B-TT Cosmo engine??

Also what would the safe boost be/driving around town boost level be??

Thanks

 

i take it that you are referring to the 13b-re 2 rotor ....well it uses the same twin h12 turbo's just different higher flowing manifolds and a couple different things...i would imagine that it would be able to boost as much as the 13b - rew which is about 16.7 psi...well thats my own opinion...we arent in japan so we have very little knowledge about this jap only engine

 

My understanding is that the Cosmo 13B-RE(W) uses two HT-10 turbos rather than HT-12s like the FD 13B-REW uses. I don't know what the stock boost level is, but the maximum boost depends on too many other things for anyone to say for sure.

-Max

 

stock boost is 9-10 on the first turbo and the second should start about 8-9 and then drop off to 3-4-5psi by redline
