does any body or any one that you know have crvtec? if yes do they have there blocks sleved or not. because im trying to find out weather or not i shold sleve my block i no i would be better but if it is not super nessary then i would rather not spend the 800.00 dollars on it and just get a good pair of cams. please give mee feed back i need to know soon.

 

b20 do not need to be resleeved. b20 can be safely bored out to 85mm for NA applications, but thats kind of pushing it. Usually people bore it out to only 84.5mm like I have. What are your plans for the b20??, all motor, or forced induction. I have had my b20 bored out to 84.5mm and revving to 9000 rpm rev limit, making 225 whp, and roughly 15000+ miles. Still very reliable. Hope that helps.

 

thank you for the help i will be going all motor so it will be reliable
