me and my friend had a discussion about the b20 vtec vs b16 motor.. he has a hatchback thats ready for a swap... which motor is the best way to go?????? and why....

 

there's no replacement for displacement

is he boosting it or what?

 

im not sure exactly... i believe hes going leave it stock b/c no money but all i know is hes having lsd tranny...

 

b16 would probally be more reliable, unless the b20 vtec is a least a little built

 

Aren't the b20 block's internals weak?

 

if the CRVTEC is built properly than it is one hell of a machine, but properly means $$$$$. if he is just planning on slapping on a VTEC head using the golden eagle conversion kit, then I would def. just go b16a...although if it were me I would save all that money and boost a stock b18b1 for the same price but more hp and fun for teh win

 

B20's have very thin sleeves, but can definitely have potential if, like stated above, done right. I would agree to not go with either, and drop in a B18c1 or even the B1. Both are a lot of fun boosted or N/A.

 

The problem with the b20 is not the sleeve. The sleeves are fine...they can hold high compression, high rpm, and boost. The problem is in the OEM rod bolts. They tend to stretch under high RPM loads...that's the weak link. 8k rpm every day is not reliable unless you have at least ARP rod bolts. I'd rather have a B20 over a B18C/B or B16 any day of the week, even if you didn't slap a vtec head on it...just by the sheer cost of the motor compared to the GSR. A B20 costs slightly more than a B18B, and you get more torque. I'm not a very big fan of the B16, and they'll cost more than a B20 for a relatively new motor.

 

thanks for the info guys.. this kind of stuff confuse me more and more everyday hahahhaaa.... heard some story that some guy has a b20 vtec and some kind of headers on hatchback running somewhere in the 12 sec on a quarter mile run...
