Since you have an investment to makee, It might be worth while
to price used NF motors (130 hp). with the 4kq exhaust these will
make 136+ hp.(4kq's have best NA exhaust systemWith high quality
gas, you should be ok with the 10: CR. Course you could also update
the engine mgmt sys with it; but, that's a lot of work. Another alternative
