Well you will need to add $500 - $600 for motor mounts...
Are you going to install it or a shop??
If you're going to have a shop install it thats more money.
The bad things about h22,h23's is you have alot of over steer and around 120 more lbs in the front of you're car. Bolt on's are more expensive for them then b-series engines.
The good thing is horepower
I have seen people put them in and there is some cutting and maybe some pounding of the firewall involved to make it fit.
I think a b-series engine would make you alot happier and you would not have to do so much stuff to make it work.
