The first thing we do whenever we pick up an older car is go through the fuel system. So when we dove into a 1985 Toyota MR2 that recently fell into our laps, we started by shipping the fuel injectors out to noted EFI specialist RC Fuel Injection, Inc. in Torrance, California.

Ooh! Good reminder - I have two sets of injectors I need to send in!

Anyone know the differences between RC and witch hunter? Better? Worse?

How does this compare to buying new injectors from rockauto etc? Is rebuilding a factory set actually better? Or are new aftermarket pieces junk?

Yes!  I sent my OE ND injectors from my FC to RC, and they fixed them up ASAP.  That fixed my hot restart problem.  Highly recommended!

“New” injectors from rockauto are going to be cheap turds that fizzle out. OEM injectors are the business, it’s why you pay so much for even reman OEM injectors.

Besides the obvious quality difference, it’s also way cheaper to have RC rebuild injectors than it is to buy new. RC charges about $25/each, but RockAuto injectors are about $50/each for this car.

New injectors will not get you a matched set, this is very important for getting the same squirt in each cylinder.

How often should this be done, 100k, 200k? Is it worth looking at the tune after this too?

I've got 450,000 on the 4Runner. Might be worth it. Mabye.

I'd like to see an answer to this too.

I'd also like to hear some good scientific tests of fuel economy and power of ~150k+ mile injectors compared with the rebuilt. I've heard anecdotes but I've never seen anything concrete. I sure would love to have a few extra hp and a couple more mpg's on my almost 190k mile Forester.

Random thought #1- When I pick up an older car and go through the fuel system, it requires a carburetor rebuild. I guess definition of older car changes from person to person. Random thought #2 If you keep pushing enough fuel through an injector, there's no time for dirt and junk to become stuck. Fuel systems stay clean in cars that don't sit still. Random thought #3 Can't remember exactly who it was that recently revealed the fact that newer injectors have multiple discharge nozzles for better fuel distribution and are better than older single nozzle style injectors which would make rebuilding old units similar to beating a dead horse. Well, maybe not quite that bad.
