If your only out for a drag car, and have the money, then do it... But this combo is NOT reccomended for a daily driver... If you dont upgrade the suspension, and do it correctly, u will have mad understeer (where when you go around a corner the car slides foward instead of turning)! Tho ppl say its not much more than a B, but u have to consider the fact that the EF chasis (much less the EC ur wanting to put that in) is built for a much smaller engine than even the B, u add 60 lbs with a B over the stock, thats fine... But if the H is 60 more than the B, thats 120 lbs total over the stock weight... (I dont know the exact weight off hand, just using 60 lbs as a guess) Thats ALOT of weight... And the EC was designed for a much smaller engine than the EFs were... Also not only suspension, u have to upgrade the brakes... Beat the piss out of the frame to get it in there... And then wire VTEC and OBD1... IMO its not worth it...
