Upgrade to Xray XB8EC

Hi,
I'm a Truggy driver (nitro and brushless) and from time to time I playing around with my Brushless Xray XB8EC. This is my back-up in case of my XT8 truggy is broken.

Today at the track I drove a friend Brushless Buggy. He have LOSI 2.0 with the EZRUN ESC and motor. I think I'm in love...

This Buggy is so easy to control and fun to drive, jumping the doubles like a Kangaroo on Steroids. After that I felt that My XB8ec is like a Tank comparing to that Losi - going slower and jumping lower.

Now to my question, any cheap way to upgrade my Xray to make it close to the performance of the LOSI? I know some drivers installed the 808 shocks but I’m not sure if this is enough.
I don't want to invest to much since my prime car is a truggy.
