well dude in that case go for it if your motor's blown cause you can always swap to a manuel later... I guess I missed the part that your motor was blown up... but realize it does take some work and there is always going to be extra money needed for getting an ecu a jumper harness if need and you'll need an engine harness built to get everything running right then you gotta figure out what you're gonna do for getting the driverside mount to work... I can say you're lowend will blow *** and if you finally get to higher rpms you'll love it but I have an f23 manuel tranny on my h22 and I hate my low end... and mine as more torque than the f20b... and according to drift there's about 8-10 less torque compared to the h22... and he says there's a definate difference.. but if you can afford the motor( cause you need one) and the wiring harness and the ecu and all the rest of the small things I say go for it then immediately start saving up for your manuel swap but if you dont have all the extra money to do the swap I say stay with the f23 just because it'll literally just drop in. I'm not trying to discourage you I just would hate to see you buy a motor then have no way to make it run your car... that would just be a waste for you.. :/ just research and price things sum more and make your choice... if you need help or want more info on the swap just pm me.
