well, i'm getting ready to do the h22 swap since the 2x f22 i put in back to back blew up. got quick question. i read the h22 faqs but couildnt find anything on the knock sensor. i have a 96 cd7 ex- do i need to run a separate wires for it or can i do without.. couple of things i found that was not on the swap guide was u can retain the h22 fuel rail but just need to switch the fuel line banjo bolt with the closed access port on the other end. any info is apreciated. thanks in advance

 

Ive never heard of the fuel rail giving people problems.

Idk how you couldnt find anything on the knock sensor.. If you google 'h22 accord knock sensor' you get multiple links all with answers..

"The Knock sensor is a red wire with a blue stripe, and goes to D3."

 

The hondapartsnow guy here and on ebay will sell you a readymade kit for any of the wires u need for the swap. Just do a search. You can also use your f22 fuel rail or an h23 fuel rail since they're supposed to be the same and will be on the same fuel filter side as your f22.

 

Mine came with it feeding on the driverside already, so I didn't have to get a different fuel rail to retain the factory fuel line coming from the fuel filter.

 

thanks peeps-found the wiring for the knock sensor- i couldnt use the f22 as mount bolts are different on the h22 mani. had not time to sourdce out a h23 mani but the fuel rail is good. getting ready to drop her in just need the lude engine mount.

 

An engine lude mount or the Hasport will do. I preferr the Hasport mount as it gives minimal engine movement.

 

i got a deal on the hasport kit so i went that route-thanks nus. i started the brackets and had to use a 93=96 p/s bracket and accord alternaotr bracket- friggin accord p/s bracket washiting the block and mount didnt line up= i thought that write stated can use accord p/s and alternator brackets. i finished rewiring for missing iat,knock and map. i also just removed map sensor from tbody of f22 and rerouted the vacuum hose to the other opening on the intake manifold. i'll try and keep post as i go along. btw, i had this h22 swap in my 89 prelude inx. i hate to part out my inx but its time....

 

anybody know compression ratio for h22 is it 10.1 to 1-was thinking of installing my turbo that i had on my f22

 

If you do, make sure you run low psi.

 

You welcome. I'm trying to get the Hasport Rear and Tranny mount for my CD5 Accord as well so that there's minimal engine movement and more torque to the ground.

JDM H22s are 10.6:1 and USDM H22s are 10.0:1. I recommend you going with Mahle's Gold Series 9:1 CR pistons because the ringlands on the stock H22 pistons are weak as f*ck, and it wont last you long before you take it back out again for an overhaul plus going with Mahle Gold Series pistons won't require you to get the block sleeve like other aftermarket pistons such as CP, Arias, etc. But I do know that some ppl runs them at 6psi tuned just to be on the safe side.
