Hello all,
I've tried searching for this question, but haven't found anything definitive. Though its still a ways off, I am hoping to add the ol' RX-7 oil cooler up front, complete with a custom fiberglass valence on this '73 1.7. In the meantime, while I've got the motor sitting here in the driveway, I wanted to switch to the heavy-duty oil pump. I have heard this is a good idea with an oil cooler mounted a ways from the pump. I'll be using the sandwich adapter and keeping the stock cooler as well. My question is mostly pertaining to the relief valve inside the motor. Do you have to replace it if you use the type I pump? Will it dramatically increase oil pressure if you don't? Any help would be appreciated. Thanks! |

if you block the filter relief valve, be sure to get a high pressure filter can or buy a filter with an internal relief valve. the HP1 filter has a 22 psi valve. the stock relief ball valve at the filter opens at around 10 psi or so.
lesser filter cans can rupture if no relief is used specially if you rev it whilest cold. since space is at a premium for the stock filter and that space is reduced with a sandwhich adaptor, you may want to use a remote filter mount, this will allow use of a much larger filter, for less pressure drop and less chance of a rupture. |
