I want to send off some injectors for flow testing and cleaning, and I was wondering if anyone had experience with either RC engineering or Cruzin performance, and which is the better company. RC's price is $24/injector and Cruzin's price is only $11/injector. Here's their websites:

http://www.cruzinperformance.com/fuelinj.html

Please let me know if anyone has used either of these two companies, or would recommend another company instead!

So does this mean that no one has ever purchased used injectors and had the cleaned and flow tested before? I find that one hard to beleive.

I had mine cleaned, but what amazes me is everyone wants to send them off to these companies.

Why not get it done locally?
In my town alone there are 4 shops that do this all within 10 miles of me.

My injectors went South on me October of 2000.
I went to my Toyota dealer where they took them out and sent them down the street to a specialty shop much like the two URLs above.

They flow tested them, checked for cracks, and then ultrasound cleaned them.
Took back to Toyota where the tech put them back in my rig.

The rig ran so much better afterwards.
Here is my flow chart test.

As you can see, a few were not putting out the correct stream, and were spurting out few, and causing the wild bucking sensation I had at the time.

The only thing these online shops do is "blueprint" which is nothing more than take other used injectors and match them so you have 100% across all of them.

But a local shop can also do that if they have several in stock.
The local ASAP Autoparts store 2 miles from me does the exact same thing.

 

Thanks Corey,

What kind of shops should I be looking for? What do I need to look up in the phone book to see who does it?

Chris

 

I'd look in the automotive section of the yellow pages, then under carbs.
Most carb shops also do fuel injectors.

Also a lot of machine speed shops that specialize in performance stuff for imports, and muscle cars do this service.

The one by me is just a normal parts store, but with a machine shop too where they turn rotors, clean heads, ect.

I have had many dealings with RC Engineering and all of them have been great.

They are tops in their field using high end testing equipment that they design themselves.

If I had any need in the future for injector or fuel pump flow testing, or maybe a throttle body overbore I would not think twice about using RC Engineering.

Thanks Corey and Gadget!

I've used both.

Cruzin wasn't set-up for my injectors off my Mazda RX-7 (high impedance injectors), but he found a way. Great customer service!

RC Engineering cleaned my older RX-7 injectors in a jiffy and supplied flow test results.

RC had a turn around time of about 3 business days.


Unfortunately, I haven't found a reliable source for cleaning and blueprinting injectors in the Austin, TX area.

It's very feasible as well.

I've dealt with Cruizin' Performance. Good service. High recommendation.

 

That's what I like to hear. I'm going to use them I beleive. Does anyone know for sure if 1995 SC300 red top fuel injectors pop right into a 1998 4-runner with the 3.4liter?
