750cc injectors for sale 300.00
So I got some balanced 750cc injectors from Marren. They are Rochester style with 8 hole nozzles. Low ohm. I have them in my car right now but they are not enough for my latest setup.
If anyone is interested I would take 300.00 for the set. They have only been in my car for about 2 weeks. They idle fine even down to 650-750 rpm at 80 psi rail pressure. These would be perfect for gas up to about 600+hp at the crank or E85 up to about 450-500 ckhp. I am just running out of fuel at 5200 rpm is the only problem.

Lets say I super charge my motor,I need extra fuel for my HFM car.Would all I need to do,is to add larger injectors?

Yes, but you cannot use low ohm injectors with your stock ecu.

I guess I could measure ohms of a stock one

High impedence typically fall between 12 to 16 ohms. Low impedence will usually be around 3 to 4 ohms.

You can use resistors for low imimpedance.
I have run larger injectors on hfm m111 for supercharge application seems to work great but I didn't have the chance to check it with wideband before my Ecu shorts because of the famous bad wiring harness

wanted to add that i have a set of e55k injectors high ohm that are a shorter body than the stock m104 injector but same plug and o-rings. They are 420 or 440 cc injectors I do not remember exactly. These are also good to about 400whp on pump gas with higher fuel pressure. I ran these for many years and I have 8. I would let them go for 200.00.

Ok so I got some ID1000s. So these are out of the car. Someone here should just make me a reasonable offer. The marrens have less than a couple thousand miles on them and work great they were just to small for e85 at the power and rpms I need. More than enough for the power on gasoline. Probably good for 500whp on gas.
