I have an si and I'm about to install my drag gen 3 kit. I would like to know what you guys think :is it worth to change my bottom end for a b18c1. What about the b20 bottom end? Will it make a big difference? I did a search and a had no luck..Thanks.

 

I always try to use what you have to keep cost down. I personally would resleve and bore it to 84.5mm.

but i thought that it would be hard to sleeve a 1.6 to 2.0, wouldn't there be some heating and cooling problems, etc. whatever other problems there is..or is it ok to resleeve and bore a 1.6 to 2.0..someone tell me, i'm getting confused again..

 

I built a B18c block Si with a off the shelf DRAG kit which ran a 13.2@108mph @ 9psi on 17's and full interior with a so so driver. It's worth it for the torque alone
