Curious on best route for a powerful all engine swap on my accord. I've read around the site and see mixed reviews on the f23engine. I see most people just swap the transmission for a h22/h23 trans. I have a 4cyl/5 speed set up already. Would it be best/ less headache to install new tranny or engine or both or even build on my set up internally? Maybe even consider kseries or other engines that can fit my chassis? My goal is to get to 200hp. I want to stay away from turbo bc my intentions are to do it myself and learn along the way.
Aloha Sir...
Powerful ALL ENGINE swap is an option. The OEM F23 bottom end with OEM K20 pistons has proven its merit at +280hp on Methanol fuel and in the 10sec range.
BUT THIS IS AN F23 SWAP IN A CIVIC HATCHBACK, NOT AN ACCORD...
My point is that the F23 as an ALL MOTOR option is under rated, due to the weak point being in the head... (which I have been currently working on, going on two years now)
Turbo wise, a basic ebay turbo kit, upgraded injectors, and a good tune can get you into the 200hp range with ease.
Limiting factor on the OEM configuration would be around 10psi and net you the high 200's/low 300's on a pump gas tune.
the limited data i have collected, the weak point on the f23 bottom end are the RING LANDS... you can open the ring gap up a little bit and easily get into the 300's at about 14psi and still on pump gas.
I don't know how much the F/H transmissions will hold at max power/torque. But the ones i have worked with are into the low 400hp range over a few years and still going strong.
Hope this helps and good luck with your build. Please keep me posted as im always eager to learn new things!!
