I'm guessing you meant b18? no way...stick with the H-series in the lude. Turbo charged lude's are so sweet, but pricey when figuring in the amount to build the block. Personally I like what Godo said, N/A's probably the best idea...and it's what I will be persuing with my lude in the future. But it all depeneds, how much are you looking to spend?
