All the engine should be fast at that kind of prices, but I think Mspeed is a better buy, the reasons being;
Kondo - Modified engine out of the box, most work are done on the P&S and Crankshaft, minor work on the backplate, carb and conrod. :) Zac/Kawahara - Not too sure who mod it, heard it was Kondo too, if that's true most of the work done should be simillar. ;) Mspeed - P&S are match before modification, mod are done on the P&S, Crankshaft, Crankcase, conrod and Carb. Backplate is also specially designed to increase flow and internal pressure. Crankcase is treated to increase strength and for better heat dissipation. Hestsink fin is machined on the button to improve heat dissipation. The heatsink is also replace with 7075 machined unit and is very light for low CG. Re-alignment of bearings in the crankcase. :D :p But of cos the extra work done by Mspeed cannot guarantee better perfomance as they maybe for look only. :cry: :( They are also other company doing modification in Japan such as NEXT and T-Force. However as far as I know ZAC TR and MT12 and T-force only have modified OS TR :p :blush: |
However I have put one of those Kondo engine on my wish list, may buy one next year if my racing budget allow.:D
