I'm going to try this experiment. I'm buying the rails Eric designed from BC and going to get the 12 hole 24# injectors since that's what the injector rating for my car should be.

Can anyone tell me the connector type or ​​​number for the wire side of my car harness to see if osidetiger has the adapter to make these injectors plug and play? Looks like the injector has an EV6 so trying to find out what adapter I'd need in case they don't know.

I completed this evening my Motor Overhaul with completed new ignition.
The same 4 hole injectors as Roger sells and new dampers and regulators from Adapt Motorsport.

With the old regulators and the new Injectors I have 10 % Higher pressure, maybe the old injectors are worn Out?

I'm not a fan of adapters. I'd get new connectors with pins and go that route if you must have those injectors.

However, 24lb injectors with an EV-1 connector are not particularly rare. Have Roger source you some of these:

Why not using these?

Thos look like 4 hole versions. I'm interested in pursuing this with a 12 hole version to see if the more distributed spray pattern has any positive impact on performance from better fuel atomization.

Roger, you have a good source for a 12 hole, 24# injector with EV1 connection?

You're over thinking this. We typically only use injectors from Fuel Injector Clinic and Injector Dynamics, the best money can buy. They don't offer anything small enough for a stock 928 though.

Here is a set of (used) 43lb injectors from Fuel Injector Clinic. I'm going to run these through the cleaning machine (we have an ASNU injector flow bench) and use them in one of my 928's.
