i need a new engine for my rs4. the last engine i had rusted cause i forgot afterburn. so i need a new engine at least a .15

OS .12 tz, insane amounts of torque and 1.5 hp. I got one, just tryn to find a fly wheel for it.

I have a HPI K12 purple head race motor for sale. It's my backup, backup motor, and I don't race much any more. It has tons more power than the stock motor, comes with a header, and an oversized race carb. If your interested I post some pics.

OS .18 CV-R. SImply cheap easy power!

i got a nitro star .15 in the classifieds

whats afterburn?
