Sleeve's
 

On a B18c1 with forged internals, at what point would i need to sleeve the block if im going turbo? If tuned right, whats the max boost i could run with just forged internals?

If your tuning is taken care of you should be good for about 450whp before needing sleeves. I've seen a lot of 500+whp cars on stock sleeves and even one 600+whp but I wouldn't recomend more then about 450whp if it's a daily driver.

Curious to know. If a D16z6 was sleeved, forged internals, and proper tuning. What types of power can they make?

Is this a full race setup, anything over 300HP is overkill.
unless your at the drag.
build the motor to 200 WHP then boost it.
ya planning running redline all the time...if so, then go crazzy.

Some SOHC D16Z6s are running really fast at drag races. There is no reason why a D16Z could not make same power as a DOHC B18C smallphobia

stock B18C ...yes. if you are talking turbo D16's making the same power as a B18C turbo mod for mod....no



and remember most people daily drive and run pump gas.
