Not too sure, I think that Neukin is pretty much the shit as far as Honda turbo mani's go. When Mike gets on you can ask him and he'll be able to tell you the best to fit your budget. That's what I like about him, he'll tell you that you can get x part for x dollars but for your application y part for y dollars would be best. He won't try to sell you something just b/c it's more expensive. For instance, the AEBS manifold on my car is what he reccomended. I was ready to buy the skunk2 or Victor X intake mani and he told me to go with the AEBS which was about $150 cheaper.
