youve got to be kidding me. how bout this....my ls vtec has been making 180 whp all motor on stock gsr cams for over a year now. it sees redline (8400 rpm) at least once or twice a day, and gets 34mpg. regular oil changes with a good tune and quality ignition components helps with longevity. as long as its all assembled and tuned the right way you wont have a problem with it. make sure u use arp rod bolts and dont cut corners during the assembly. IMHO there is no replacement for displacement. youll be happier with the 2.0l over the 1.8l bc of the tq when daily drivin. if u are only gonna spray a 50 shot the stock 84mm sleeves will hold up fine. esp since i doubt youll be spraying all the time driving 100 miles a day. hell there is a stock sleeve b20vtec on boost makin over 500+ whp. so if the sleeves are weak you would think they would crack on that build right? youll be fine with the 2.0l on a small shot if its all assembled, broken in, and tuned right. and just so u know...they both take the same amount of oil as any normal ls, b20, gsr, or b16. end rant.
