rb20 internal upgrades
 

aight, ive read some bits about the actual displacement upgrades for the rb20, such as boring it out to use 80 or 82mm pistons and using the crankshaft from the rb25 or rb26. wat i would like to know is, is the rb25/26 crankshaft practically just drop it in and go? or wil more work be necessary? how bout other parts such as bearings?
