Direct experience with them. Very good. These are Bosch injectors. Running them in my personal ZR-1 and in multiple client cars (had them in the car when I received). No problems tuning with them.

Sent from my SM-G950U using ZR-1 Net Registry mobile app

Since the mid-90s RC Engineering has had 1G LT5 injectors available.

RCs are not near as cheap as the stuff you can find on eBay, but they are a heck of a lot more consistent across a set of 16 and they'll last almost forever.

When I owned Barney, I put a set of RCs in the engine at the same time I had the late Jim VanDorn do his 500-hp "Street Skinner" engine package its LT5. Those RCs were installed in 1998 and were in the engine when I sold the car four years ago. I pulled them out a couple of times betwen '98 and '16, ran them down to RC and had them tested. Each time, their flow spread was the same: 1 to 1.5% and their spray patterns were just about perfection.

Het Hib, any idea where Barney is right now? Hope it is now in a good home. After you sold it, didn't the new owner also sell it? --Bob

If you want good injectors, use a few of the sources listed above, but keep in mind, a some of that stuff is just used injectors which have been cleaned ultrasonically. They are not new and are not even "remanufactured" in the sense that legitimate business use that term because stock LT5 injectors cannot be remanufactured nor can most other injectors used in an LT5.

If you want the best injectors for 1G LT5s, go to RC Engineering. More than two decades ago, the late Jim Van Dorn and I worked with RC Engineering to develop a set of high-end replacement LT5 injectors which would support 500-525-hp yet offer good driveability in all situations. RC Engineering continues to sell them today. They are a derivation of the Lucas rotating-disc injector design which was a far better choice that either the Bosch pintle (ie: Ford) injectors or the ACD ball and socket design.

If you are interested in the best injectors you can get for an original LT5, contact RC Engineering and ask for Wayne San Miguel who understands the 1G LT5 injector situation.

RC injectors are not the least expensive but they are an outstanding product. I installed a set in Barney's 500-hp Automasters "Street Skinner" engine in 1996 and they were still in the car when I sold it 20 years later. When I owned it, they were in-and-out a couple of times during plenum-pulls. I sent them to RC for cleaning and retesting. Each time they came back with a flow spread of 1-1.5% and "execellent" patterns.

Since I sold Barney, I continue to use RC Engineering injectors. I have a set on my '04 Z06 which have been there for about 13 years trouble-free. I just had RC clean the OE injectors out of my '12 ZO6. They came back with a flow spread of 0.9% and exccellent flow patterns.

I have Southbay injectors in my car 1990 #254 they were installed when I purchased the car in 2018 and have not been a problem.

Not a clue.

The car has changed hands twice since April of '16 when I sold it to (a person) in Florida. He kept it for a couple years then sold it to a guy in the Northeast. that dude had it for less than a year then took it to Barrett-Jackson Northeast and auctioned it off. I lost track of it at that point.
