Sorry All, Haven't had time to get on the comp.
There is NO physical external difference between the Just Jap pans and the ET Perf.(High Energy) pans.
As I have previously stated, We make both ASR and HE pans.
I think you might be comparing a Race pan with our Street pans (S/S or S/C), two completely different designs for different applications. The Street pans are the entry level pans designed for street use (6.5 Litre capacity). The race version is obviously designed for racing (8.5 Litre capacity).
The only difference between ASR and HE is the internals.
The ASR pans are generally more complex and contain more, as we update our designs.
The capacity of all the oilpans is engraved next to the Drain plug on all ASR and High Energy oilpans, along with a serial number that corresponds only to our work history logs. That will tell us: When it was built, What it is and Who it was for, as we do pans for many other Suppliers/Speed Shops.
If anyone would like to query a serial number of any ASR or HE pan they have feel free to email
[email protected].
Thanks
