ford cvh pistons do not like boost , ive got the remains of a set in my garage. the ring lands are weak!!!!

if you are building on a budget(like myself due to buying a house and more recently a Scooby) , you could try what i have done.

use vw golf 1600cc pistons(80.950MM with really good ring lands)
use vw beetle bushes on the rods(the pins are smaller)
take 4mm of your block
remove 5mm off your head bolts
efi inlet manifold , gotech and 500cc injectors , t34 , vernier

the car to tune down here is a golf , so parts are readily available and bloody cheap

im aiming for over 200bhp
