What exactly is this.
How hard is it to do this?
How expensive is this?
How much power does it have?
Are there any maintenence problems associated with this engine?
Ive got a 93 SI and was considering this as an alternative to a full on H22 swap.
an alternative, but here are the downsides
1) will cost as much or more than a full h22a swap unless you have both engines already sitting
2) not nearly as reliable
3) to take advantage of the h22 head, the h23 block will need oil squirters machined in, which means a lot of work...without, the h23 block will overheat and eventually something will give at higher rpm......h22 block has these oil squirters to cool the piston/rod
4) you'll end up making a LITTLE more tq and the same or slightly more power.....i've heard that torque will be a lot better, but compare it to an h22a with intake/exhaust and you've got no advantages for a lot more work.....i'd never consider this
