Tee6gen,
The auto isn’t going to hold up to the kind of power the H22 should make stock, forget a supercharger. I’m not sure why people think the 6th gen Accord is a bad canidate for a manual as mine came that way stock. No custom lines, holes, pedals or master/slave cylinders are needed, though there is nothing wrong with using a SS braided line instead of the stock rubber one. I highly recommend you use the manual that you are getting with the H22 as it should be LSD while your auto certainly isn’t. Additionally instead of spending a fortune on a high stall torque converter (and lots of auto trans rebuilds) Spec has many excellent clutch options that will hold the power without a heavy pedal feel/heavy pressure plate. (Stage 3 is my favorite, very streetable, reasonably priced and can handle all the power the SC could make)
All this said, is there anything wrong with the prelude or reason you don’t leave the H22 in there? Does it have the ECU or other parts you can use?
