Alright gentlemen, I'm far from new to Honda's in particular the 5th gen Accord.  I've been modding mine for a few years now and I'm always looking for something more here or there.  I've got the typical H22a1 swap and Type S pistons, camshafts, exhaust, etc.  My question is whether or not the H2B tranny adapter and B transmission would fit and or have any performance gains for this car?  I know the kit was made for Civic's and Integra's that swap an F or H series motor to retain their tranny.  I simply want to reverse the process if possible as long as it would net some sort of gain.  I'm thinking along a B18C5 tranny; however would the weight of the car present a problem and or make the better gear ratios null because of the weight?  Its was simply an ideal that popped into my head lately and my normal forum hasn't touched on it yet, nor do we have the uber tech savy there anymore.  Any help would be greatly appreciated in this ideal/endeavor.
