I know of someone who swapped an EJ20G engine and then had a bad block, so he used a USDM EJ20 shortblock then with EJ20G heads.

I would say yes, that you can use atleast the EJ20G shortblock with your USDM heads and intake manifold.

Unless you have fragged your block, I wouldn't even consider this. And as has been mentioned, putting a 12-15 year old engine in there in place of a virtually new one is a risk. More and more people recently are getting old swaps into their cars and having them spin bearings in the first 6 months. You just can't trust the stuff that's older.

Furthermore, closed deck is way over hyped, and the early heads have HLA's that don't like to rev very much. Unless you were going to use an STI block (with solid lifters) and do a full rebuild from the ground up, this is a stupid idea. And closed deck engines will only be '94 and earlier. There really aren't very many of them still floating around. I do have an EJ20G closed deck shortblock that needs to be gone through if you are serious about this project. But, you would be far better off sourcing a V7 STI shortblock, and mating it to your heads...

Not in my mind, it isn't. I would sell my shortblock for $250 plus freight.

HLA on the ej20g's dont liek to go past 8K. unless you have a turbine that wants to go past 8K and the other such, HLA isnt bad. no need for mechanical whatnot adjustments. the normal Sti's had HLA's in the G motors. the sti-RA's were the only G that will spin past 8K happy. to 9, or 10K if you dont have a rev limiter (and want to suffer the consequenses....)

unless you actually can argue that you can go past 8K and make power, going HLA isnt bad at all.
