Sorry to ask but hows the quility of the manifold, Ive heard heard some horror stories from a few guys in my area, I had a friend put a "XS power" kit on his b20 Honduh motor and the manifold cracked after about 2-3000 Kms on it it just couldnt take it and this wasnt the first, I hope you dont have these problems and good luck on the project if all is well it should go like pretty good as long as you dont have too much lag, Any new pics of the build?
