That's an s14 engine - look at how it notches down on the firewall side.

Lets start over.
Why are you replacing the HG at all?
where did you get this motor from?
yeah.. i looked at this car before getting my current one... leaked oil outta the hg like crazy.lol.
you pulled the whole motor out just to replace the hg???lol
