Also things that will need attention. Coil conversion is almost a must. The stock coils break often, and when they do replacements are hard to find and are only available as used.
Front and rear main seals leak if not replaced. So far every G motor I have ever seen has had one or the other leaking. New oil pump is also a must, as the stock ones seem to have the internal hardware back out.
Other then that. EJ20G FTW!
