Sounds good
Mine was an SX that turned into an SX2.
I fitted the alloy gearbox top mounts and the new gears which relocates the slipper.
As for 3rd party upgrades, they are expensive but I like the Ghea big bore pistons.
Steve rates the FAB, but I never bothered with that.
Based on the fact that you can drive I'd go for a 6.5 V3
I'm running Nosram LIPOs in my SV, but will be moving to Speed Power when they need to be replaced.
Orion's in my Rango.
I run a 7.5 V3 in my Durango, but it is silly efficient in putting the power down!
March for the 22??? I've cancelled mine and am sticking with the SV, too much time and money. For cheapness I nearly went back to my old B4 from Dave Moore...
Oh and the RW spur gears for the SV and SX rock
