Is consumption an issue? Plus what engines do you have in mind? There must be a long list but firstly you need to make up your mind about Honda or Toyota. B18b, B16, Red tops black tops, I can never decide lol
My mechanic is a good guy and he is good with swaps I can arrange a meeting and you can have a discussion. If you feel satisfied go for him if not then don't but if not him I can ask my boss and suggest a few more (he has a B18b of the Intergra in his EG)
P.S I won't suggest a Turbo charged used (kabli) engine
