I heard that you cant run ITR cams with a stock b20 bottom end because of piston valve relief.Is it true?How much valve relief do I need?I need to rev safely to 9000rpm

Those are two mutually exclusive statements.
Like a b16 and torque

 

are you referring to the b20a5?

if so, good luck getting it to rev that high without blowing up.

 

it will go bang

 

Maybe not 9000rpm but yes to 8000 rpm.Does anyone know how much valve relief I need?B20crv block and b16 head and itr cams

 

Most likely the engine would blow up.

 

dont even waste your money and time...

 

Rod stretch and broken rods are awesome to see. please post pics when done.

 

If you cant build a B20/Vtec to rev up to at <U>Least</U> 8500,you dont know what the hell your doin.Ill send you the pics of a 13sec maybe high 12sec car when Im done!
