Max Psi On 14b?

[LAZPNO]

I'm trying to build the car up over the winter and see what it runs after that. Gonna make sure everything is good first. Anywayz, 3" turbo back w/ ported 02 and supra fuel pump (hardwired) will be done in Jan. After that i was wondering the max psi i should be capable to run without leaning out the engine, this is without fuel controller and using stock injectors.

Hacked air can.
K&N filter.

P.S. i plan on leaving the MAS alone until i get an afc and 550's or 3kGT injectors.

Thanks for the info.

I would vote 16-17psi

I think efficiency on the 14B starts to fall past 15-16 psi .. I've heard of people bosting a 14B to 21psi, but I think your just pushing hot air at that point and without a large FMIC it will do you no good.

16-17 psi on pump. If you have a modded sidemount, 18 psi. Front mount with 550 injectors and a AFC, 20 psi max. At 20 psi, expect the life of the turbo to decrease and porting is recommended. I would rather upgrade the turbo than run a 14b at 20 psi though.

Just my .02 and have a nice day!
