ITS WORTHLESS


For the money and time you would put into it to make it work you could have a complete H22A swap.

its not as easy as it sounds. the guys that did it on h-t had parts and machining readily available.

the only reason the "g23" frankenstein motor had such good power is because its HIGH compression, he is running h22a4 pistons and the f23 block was overbored to 87mm. h22 pistons have a 10.1:1 compression ratio and with the h22 piston extra 6.3mm stroke and smaller h23 combustion chamber he calculated about 12.5:1 compression but it didnt fit in the head so he had to hone the chambers which lowered CR to 12:1 and with the head gasket he estimates about 12.25:1.
