Hi,
In our previous discussions regarding L Series EFI on a W53 head you mentioned that you know guys who have modified these heads to run EFI.
May I get contact of one of them so that I know what is in store for me before I take my W53 for drilling?

Hello Antony
I dont think the 160J (I think it was also called a "Violet"?) was sold in
Australia. Therefore no one knows much about them here in Australia. Only
a few old rally enthusiasts, like me, who remember seeing the "works" Datsun
Violets running in Australian Championship Rallys in the late 1970's, using
260HP EFI Lseries engines. I know you had them in Kenya. Didnt one win the
East Africa Safari - driven by Sheka Mehta (cant remember how to spell his
name)? ! If so your 160J would be as legendary in Kenya, as a P510 (Datsun
1600) is here in Australia.
I think you should be able to modify a W53 head to run the EFI injectors.
You would need to drill and tap the large central hole above each inlet port
runner and grind or drill out a small tapered channel downstream of the
injector to allow the fuel to enter the ports smoothly. Just as you
described. I know some have done this in Australia.
If you are running a mechanical distributor, how are you timing the fuel
injection?
What fuel pump/pressure regulator did you use on the EFI setup?
