I can't say anything about Kleeman from your side of the world. They may be as inexpensive over there. I can say for 3.2 liters, these motors will hold their own against a lot of larger displacements. But, I not going to win against an all out race car...with several more pistons, and displacement. It's not comparing apples to apples. It is cheap HP, for what it is...you can't make it any faster than what mods are available. So, pick what you want to run against. Hell, I will race anything, as most things are larger displacement, and higher priced cars than mine. They SHOULD win, but, they always don't and that is the smile I enjoy most....
