ok guys i have made up my mind i want to boost the b20 whats the best manifold design to go for either the top mount or the ram horn design and what would be the best sleeves to go for as i am planning for 500whp any help would be most apprecited thanks in advance,

ps i am a newbie so wont understand any abbreviations so when replying please keep this in mind

 

Sell the b20 and buy a b18 to sleeve.The b20 can have problems when sleeved.You can make 500 hp with most any manifold with the right turbo choice.Any of the recognized sleeve companies can hold up to 500+ hp.

 

aroon i'm with you i wanna boost my b20 i keep hearing about sleeves being bad but i also hear that if it is set up right then you have no problems. if you find any more info on boosting the b20 let me know.plus the compression on the b20 is very low so boost is a MUST!!! lol Also the b20 has more displacement.
