yeah. for a start you need to take the crosmember off the box.
and turn it clockways to clear the starter hump of the tunnel. when its in you can rotate it to its normal position.
ps. also helps to tilt the enging down aswell.
no oil pump on a rb can take the harmonics of the crankshaft at hi revs.
if your buildng up a 30 bottom end and still using the rb30 crank. you will be limmited to 7000rpm.
if you want to rev it more you gonna need an external oil pump set up or a ati harmonic balancer.
also using a standard wieght flywheel will help to.
