haha agree with wardy, if its a street car then go for a drive in a 150rwkw 1200 first and see what you think
i had way less than that and it was more than enough to make the speedo more of a novelty than anything else when you gave it a bit

im wanting to get around 180rwkw, which i figure on the street should be sufficient to have bad traction issues in 3rd...not that i'd drive like that on the street or anything
