The best upgrade so far on my 72 Datsun 510 Wagon!
By Chris H on February 27, 2018
I own a 1972 Datsun 510 Wagon. It has a V6 engine swap out of a 87 Nissan 300zx with 5spd trans and custom headers, Summit ignitin box. Without going thru the headache of deciphering wires for the computer, there is a place that modifies a Nissan V6 truck TBI manifold to accept a Holley 2300 2bbl carb. I was running the holley 2300 350 cfm carb for years. The performance was great, but in the back of my mind I really wanted fuel injection for the reliability and cold starts in winter.
I had my eye on a competitor's 2bbl EFI for months but they couldn't tell me a release date. I just happened to be Googleing 2bbl EFI setups and low and behold Holley had just literally released this 2300 EFI.
I immediately made the purchase thru Holley.com and the box arrived in just a couple days.
I ordered the 2300 master kit in shiny finish since it was all that was available (I really wanted the black). My son and I opened the box and inventoried the parts list and started the install.
The install was very easy, took us 2 days total from opening the box to driving the car. We had only one issue on the install, we had an erratic idle so I got on the Holley Sniper EFI Facebook page and the people on there steered us in the right direction for trouble shooting. Turned out we had a kink on one of our fuel hoses up at the tank that caused the issue. We rerouted that line and fixed the issue.
After the easy install, the initial programming was simple on the handheld screen. After that I have been so extremely happy with this purchase that I don't think I will ever go back to a carb again in the future.
The performance of my 72 510 Wagon has improved so much it's incredible. Fires up first turn of the key every time without getting in the car, even when it's 16 degrees outside. The butt-dyno says there's a significant power gain and fuel mileage has improved.
I am so glad I didn't keep waiting for the other guys EFI to come to market, I'm 100% happy with my new Holley Sniper EFI 2300.
I have been recommending the Holley Sniper EFI to a lot of people and the Holley Sniper EFI Facebook page for quick Q&A. Thank you for this awesome product.
Best money to power investment I ever made

This EFI was easy to install. It woke up my Inline 6, 200 C.I. engine. All I can say is AWESOME!
