Today i've boosted my fuel up to 55 psi from 40 psi with a AEM regulator. But is it okie to drive it with the fueL boosted up as much as a type r?

My mods right now are b16a1 with CTR pistons and higher compression Mugen head gasket.

 

 

i would suggest setting your fuel pressure to 42psi,

id say that 55psi si too rich and will affect your power and mileage...

t..

 

for ur engine, i think 55 is too rich also..

i would say like 42-44 psi
