RE: RS4 3 rtr+ big block conversion .26 .21
Yes, but parts add up. The thing about hpi is their parts are affordable but parts do add up. I don't even know how much I spend on my rs4 anymore because I buy all kinds of parts for it. C-Los, I almost split my engine in half last time when I hit that same speed bump. My car flipped like 5-8 feet in the air and landed upside down. Engine heatsink grinded on the cement and ripped all the zip ties off the head; the antenna broke in half, supposed to be flexible. The engine did live thanks to the roll bar.
A word of advice to anyone trying to do a big block swap in their rs4, try to be conservative. Go for .21s not .26+ engines. The torque is too much. Get a .21 and rev it all the way. It is not the drivetrain that you have to worry about but the gears themselves. No matter how great your gears mesh, they will strip sooner or later (too much torque). I have to be conservative on the throttle for take off.
