Which motor would be faster for a civic a gsr or a B20 out of the crv's?
I have about 10k and I want to get to 13's fast as possible? So which one would be better? Also which one would be faster with a turbo?
in stock forms GSR is quicker...alot quicker. b20s are good for their torque and can be a crvtec. They're also somewhat good to turbo (sleeves are kinda thin, and not many companies make pistons for them).
2.0 liters > 1.8 liters
with 10K, you could make the b20 faster than the b18c
So you think I would get to 13's faster and cheapier with a gsr than a b20vtec?
:roll: 2 tenths of displacement doesn't make that much of a difference. with 10k you could easily build a 12 second B18. As 92civicb18b1, there isn't a lot of aftermarket support for the B20.
With 10k, you could sleeve a B18 to an 84mm bore (2.0L displacement), build a solid bottom end with forged components, build a head with a reliable valvetrain and good cams, and still have money left over for a good engine management system.
The only part that is really different for the B20 is the pistons...they have an 84mm bore instead of an 81mm bore. We use CP Pistons for 84mm blocks. They are available in a variety of compression ratios from 8.5:1 to 12.5:1, and have proven to be very reliable under extreme load.
