I removed the Multec injectors in my 92 Z28 with a 5.7 liter engine. They are stuck from sitting too long. Who makes a quality replacement injector that fits like the original? I prefer not to have yellow or pink or some other bright color. Gray or black would be great. The GM injectors are $80 each. OUCH!

By the way, it was a royal PITA to get the lower front bolt on the passenger side out of the intake runners!!!! Be prepared to take your time when you decide to replace your injectors.

Injectors?

Start to finish about 2.5 hours or so :-)

Well, for quality injectors I would suggest just getting the Ford Racing/SVO injector and calling it a day.

Best way to do it would be to change the injector constant in the chip.

Injectors will run you about 220$ or so.

Stock replacement ones are junk and you pay way too much for them.

Do you have a part number for these? Can I purchase them at a Ford Dealership or where? Will they fit like the stock injectors with the lock ring?

Thanks for the advice!

Leonard

 

Check the rating on the Ford injectors. I think they are rated at a lower fuel pressure than the GM injectors - i.e. they will flow more fuel than the rated value at the TPI's fuel pressure. I think they have slots for the locking clips, but can't confirm that 100%.

I think they are based on 38.5 psi, whereas the GM's are at 45psi (someone please correct me if my numbers are off).

Jeg's has them:

Get the SVO injectors, and get and adjustable fuel pressure regulator, cuase you'll need one eventually anyways.

 

I won't be changing the fuel press. reg. because the car only has 125 total miles on it. I just want to put a quality injector on it so I don't have to do it again.

What does the stock GM injector flow? 24 lbs.?

I would like to find someone who has done this swap so I make sure I am getting the correct injectors.

 

go to the summit racing website (summitracing.com ?) or better yet give them a call. Members here use the SVO injectors all the time.

According to the ACCEL fuel injector catalog your stock injectors were 21 lbs.

 

I am looking for those people that are using the SVO injectors so I can see what they used and get the correct part number.

Thank you for the post!!

 

I have a set of 8 injectors that I bought new last year from Advance Auto,only used for 8k miles. I just upgraded to 24lb injectors and I have these 19lb's sitting in a box showing absolutely no signes of use at all. I want $110 for them shipped anywhere in the US,that is 1/3 of what I paid for them new and will not accept a penny less. I have no trader feedback on here but I do on www.corral.net (zx3) www.popsracing (zx3) and Ebay (danthelister). I accept USPS money or PayPal - Welcome for payments. tabesperon@yahoo.com is my email

 

That's amazing. I would see why you wouldn't want to change anything, and you shouldn't (I'm assuming that those are original miles on the car, or is it the motor?).

 

Thats the total on the car!!

 

I believe that 305's has 19's, and 350's had 22's. I put Accel 24's on my 350.

 

SHOW US PICS OF THIS CAR! IT'S GOTTA BE BEAUTIFUL!! You came across one with only 125 original miles on it?!?!? DAMN!!!

You could do what I did. Send your stock injectors off to Cruzin Performance. The owners name is Rich, and he's a REAL nice guy. He took my injectors, on my car, which sat for 6 years, and has 96k on it, and rebuilt them, with new o rings, pintle caps and screens, and sonic cleaned them. He will even send you a before and after flow chart. He got ALL of mine in equal specs. I had 2 injectors hardly flowing at all till he rebuilt them. All that for 100 dollars total, including shipping. You won't be dissapointed. Besides, I'd keep a car like that all stock. That is one of a kind and a serious collectors car.

 

I don't think Rich does Multecs. The Ford ones won't look like the Multecs either. If you still want working replacements use the search feature and type in Ford Injectors. You should come up with a slew of threads.

 

I bought the car new. It was the last car built at the Van Nuys plant prior to it closing.

 

Just a note on this.....the bosch's are louder than the multecs....just so your aware of this and don't think something is wrong when you install them.

 

125 miles !!!!!!! How could you have kept that car for 14 years and not drive it everyday. Id like to see this car.

 

Barrett-Jackson anyone? I'd imagine that car would sell for a nice $.

 

Give me your e-mail address and I will send you some photos.

I cant wait to see what a 125 mile Z28 looks like. Usually you only see the Turbo Trans Ams or GTA's with this kinda mileage.

 

Just sent the photos to you.

 

On a car like that I think that I'd just bite the bullet and buy a new stock set from GM.

If you know the part number you may be able to get them for a lower price at gmpartsdirect.com

 

I am going to send the original set to Rich at Cruzin Performance to have them cleaned. Then I will put them in storage. I am ordering a set for an 87 IROC 5.7 which I will leave in so the car will start and run better. Rich suggested this and I think he is right on the money.

 

What type are you going to put in the car?

The Ford 22 lb. injectors are pink ya know....

 

I am going to put a set of original 87 5.7L injectors in the car. They will look like the originals except the plastic on them is black instead of gray.
