Sick dude you're in San Diego. I will be in San Diego in three weeks. will definitely hit you up for pics or drive. I Know a few other 3rd gen owners in sd also.
hey dude sorry i never cruise around on prelude power . usually serving the lude ha. but yeah. this mod is quite extensive and requires a 3 axis hand mill. (enco or bridge port) and a lathe. i converted all the header hardware to stainless allens as well. and because of clearance issues the bolts alone are length specific . but you need to get the original manifold gasket from the b20a and lay it down on the flange of the h22. you will see where you have to slot the header stud holes. 2 out of the seven or nine (cant remember) holes line up with light die grinder. but the others need work. and the two out side holes you have to add metal to give you more rigid seal surface. and mind you after all this you have to face the flange sealing surface to eliminate warpage due to machining it. so......... thats just a taste of what it would take but with what i had at my dispossal i did it for 120.00 including the header wrap which is recent. but i can show you more pictuers if your serious about attempting it. and it makes awesome power since its a little bigger primarys
