thats it in a nut shell. u drop in a stock b20 vtec and rev the piss out of it good luck. build it a lil before u drop it in or dont get all vtec crazy and u stand a good chance of having a reliable motor.

The only bad thing I've heard about building a B20/VTEC for high performance is that they have thin sleeves.

b20/vtec, and ls/vtec can be reliable.

i have heard so many retarded people say they have to many problems. They have problems cause the people who built them, don't know what they are doing.

just do it right. and you won't have an issue

exactly.. my personl experience: 5 years, about 50k, great power, 30mpg, never had to open it. leaks nothing.
its all in how you put it together. do it right, do it once.

ummm. ya i alreadybuilt it and found out all the info i need i broke 203 to thw wheel and not done till i have 220-50 all motor and tryin not to spray but i might have to

be careful hitting vtec all the time, those rod bearings don't hold up too well in high rpms, had it happen to me w/o vtec. people said it would handle 7k all day and I never brought it past 6500rpms but developed a rod knock anyway with black and blue bearings

i have a friend doing a B20VTEC swap now. i chose not to do the head swap and did a 75 shot. head was remilled and ported w/ a 5angle valve job. Crower 404-2 cams, ARP head studs. i made 203 / 197 @ the wheels. 156 / 148 NA. (that was stock injectors, and pump gas. i've got RC330ccs' now and 106 octane to mix on the next tune) my friend is wanting 180ish+ whp. *shrugs* we'll see.

That has nothing to do with VTEC or RPM.

I revved my stock GSR block to 9900rpms for oh i dont know, about a year. then i sold it, then someone else drove it for about a year before the oil pump failed.

If your motor rod knocked it was because of an oil pressure failure or an incorrect bearing size

We found out that the problem was that someone had switched the #1 and #4 bearings in the block. The #4 bearing was too lose which caused it to spin, and the #1 bearing was too tight in which the crank and rod ate it up. So we'll have to go with a new crank and rods.
