I don't know if this is a good Idea but I was woundering if I should buy a B20 to replace my good GSR block and fit my head with it ???

Or should I keep my engine? or any better setup ???

 

Stick with your GSR block, it's a little stronger from the start so you're a little less likely to break stuff. Then later on you can sleeve and build it to displace just as much as the B20 ever would have. Just my $0.02 tho

 

Cool thank's
