IIRC Betty's 914 is a stock L-Jet; does the Raby cam require any other mods ?

great news! I'm sure Betty will be glad to be behind the wheel again even more so when it's freshly wrapped in leather!
good work Clay
now, on to the 4.X?

Nope... the L-Jet works fine with the cam. The only other mod was using a bus throttle body that is 10MM bigger.

Still hunting for a 3.6 engine to use for my car. They seem to be getting rather rare.

Great news. Hopefully Betty likes to hotrod.

Glad to hear it is working!
It felt pretty bad to drag you both away from her car to have you help with mine. Hopefully we will have them all back on the road in the new year!

Clay,
if its an L-jet, is it a 1.8, or did you increase displacement? if so, which injectors are you using and how did you adjust flow with a L-jet to increase or change fuel flow/output? (tune A/F)?
Thanks.

Don't mess with the AFM internally. The only thing you should do is adjust the air bypass screw. Messing with the insides of the AFM requires special tools to calibrate it correctly.
The 912E was a 2.0 914 engine in a 911 chassis, with the L-Jet added onto it. They used different injectors than the 1.8L car, but the factory 912E injectors are basically unobtanium these days. So I used Nissan/Datsun 280Z injectors. Nippondenso license built the Bosch L-Jet system, and it was installed on most of the Nissan and Toyota product line in the 80s. The Z injectors are the replacement called out in all the parts catalogs for the 912E. They bolt right in with absolutely no mods needed.
That and the bus throttle body conversion make for a strong running engine.

Congrats. You've been the shoemaker with holes in his shoes for lack of time. She has a super car.

so theoretically, one could replace a 2.0 set up with d-jet, with an l-jet system, just source these Z-injectors and a bus intake manifold ?
if I have to rebuild my 1.8 I could keep the l-jet, but go to 1911 stock P&C, heads etc,
.
Ive heard the L-jet systems were used on many other cars, and seem to be a smoother more dependable system overall than the d-jet, so it might be a better option and affordable one going forward on these.
thanks for the info. When I saw Betty's car at last years' Octeenerfest I did not know it was the 912E set up. Hope you guys can make it next year!

It's not a 912E system. It is the 1.8L-Jet with bigger injectors. I just added the bus throttle body with the engine rebuild.

Congrats!
^ditto!
I've run stock 1.8 L-jet on a factory 914 2.0 before, I think I swapped to newer Ford 19lb injectors. (and a Mallory distributor later on)
