JON3KGT- 136hp? youre giving them too much credit. most of them up out between 90 and 110hp at the crank. unless you swap in a motor and get an instant bazillion + 1 whp.
now back to the nissan. that manifold looks too small. seems like you might be able to squeeze some more power out of it if you ran a larger ID and OD to accomadate.
