Re: Fuel Injectors
 

Are we sure they are 21#??
I was checking Summit and went throught te shop by make and they show that the ZR-1 stock replacement is 24#??

Anyone?

Re: Fuel Injectors
 

Yes, positive... they are 21#, I have them too.

Theres the link for the summit page.

If you click on overview it shows 24# for 92-93.

Are they wrong?

Re: Fuel Injectors
 

They are wrong.
What you need is 21#, ACCEL p/n 150121
http://www.accel-dfi.com/ProductDeta...minselection=2

I'm pretty sure that the standard 'Vette with a LT1 engine uses the 24#'s.

I tried contacting the folks at Autoshop Racing Engines by phone all day yesterday without any luck so sent them an e-mail last night. Got this reply this morning:

Hello,
We do no longer carry Fuel injectors.
Thanks
Birgitta


I didn't see the 21#s listed on the AtlanticSpeed website but did find them on Summit Racing's site listed @ $269.95 for the 8-pack. Is that the best deal around at the moment? I'm in a bit of a pinch as I'd like to get them installed this weekend.

btw - I did talk with Marc Haibeck yesterday and he said the Accel injectors are a good replacement. He repeated the information about needing the special o-rings is incorrect. They are not needed.

btw2 - Where can some information be found on the Delphi injectors? Thanks.

Re: Fuel Injectors
 

I'm fairly certain that I saw a posting last week from Uly (Guinessdude) saying that he took the last three sets that Atlantic Speed had in stock.
Summit is your best bet, especially if you want them by the end of the week.
I'm sure other places stock them, but they probably will want the usual "Corvette Tax".
Make sure to specify they "New Style" not the "Yellow Ones". Make a big deal about it when you order, that way the request goes all the way back to the warehouse to the person who actually pulls them off of the shelf and puts them in the box.

Don't know anything about the Delphi, I didn't research them when I replaced my originals last year.

Good luck!!

Re: Fuel Injectors
 

Thanks! Got 'em comin' from Summit with arrival slated for Friday. Hope to get "The Beast" out on the road some over the weekend...!!!

Re: Fuel Injectors
 

:censored: - figures, an hour after placing the order with Summit I get an e-mail from AtlanticSpeed informing me that they have received more inventory. The difference in price would have covered the 2nd Day delivery charge from Summit. Timing is everything...!!!

Re: Fuel Injectors
 

tccrab....

Still in Folsom? I'm in Briggs Ranch and thought I was the only one in the city with a Z! Anyhow I have a black 91 that needs injectors. Is there any place in the area that you know of that carrys them? Tognottis?

Thanks!!

Roger

Re: Fuel Injectors
 

Roger:

I live behind Folsom Lake College on Silberhorn Drive, only a couple of miles away from you. When do you plan on changing them? I'll PM you my phone number, I'd be glad to help.

The closest and cheapest I found were at Summit, and they are over the hill in Reno. Most of the local shops can get them, but once you tell them what they are for they add a 200% Corvette Tax, AND tell you that the book says they aren't for a ZR1. Duh. Tognotti's might carry them, and they might even be open tomorrow.

There are a couple of ZR1's in our area, Bob N. at the Smog Shop on Blue Ravine has a red '91, and I've seen a red '90 ZR1 at the UC Davis Medical Center over on Iron Point Road.

Re: Fuel Injectors
 

Cool! Ever since the first time I laid eyes on a ZR-1 I have always looked for the emblem on the rear of passing vettes. With that, I have probably only seen about 10 Z's in my life! One was here at Folsom OSH and was a white one....you?

Tognottis does not carry accell in stock (no suprise), but Summit has them and IS open tomarrow!!! (big suprise) Guess I will be taking a trip to Reno today or tomarrow. I gave them my car year and they claimed to not carry the right injectors, so I grabbed the part numbers from one of your earlier posts and purchased them that way. Hope they work!!!!

Re: Fuel Injectors
 

Wasn't me, my '90 is Red with Saddle guts.
The white one was probably Patton's car, he was trying to sell it last year, haven't seen any posts from him since.
There are half a dozen or more ZR1's in the general Sacramento area that I know of. I've seen 3 of them. I can't wait to see Bill's car at Vette Magic on June 2. He had his engine PC'd Candy Apple Red, should look SHARP!
Think you'll have your Z running by June 2? Vette Magic is the big once a year 'Vette show at the Marriott on Sunrise and I50. Should be HUNDREDS and HUNDREDS of 'Vettes...
Give me a call, let me know when you plan to yank your plenum and I'll make sure to squeeze it into my schedule.

Tom

Re: Fuel Injectors
 

Patton did tell me this winter (in a PM reply to my PM to him abt where have u been lately?) that hiz ZR-1 is for sale (he may have sold it by now)--And he has not been here (the forum) for a year now!

Re: Fuel Injectors
 

Well just got back from Reno and have 16 Acell 158021 injectors. The connector is not the same so the groves don't line up. I guess I'm just suppose to work it on til the connector snaps on. My only other concerne is that this new accell injector is slight shorter then the stock ones. Will this cause problems with the fuel rail and how it bolts to the intake runners? I't looks as if I just bolt the fuel rail as is with the new injectors, that the injectors won't fully seat into the injector hole. Any thoughts?

Also....Summit Racing is quite the toy store!

Re: Fuel Injectors
 

You have to remove the tab on the connector for the primary injectors. I just used my dremmel tool with a small grinding wheel.

They don't bottom out into the fuel rail like the original Multecs did, you just clip them into the first slot on the top of the injector, I've had no problems with leakage.

Good luck!

Re: Fuel Injectors
 

I need to replace the injectors,no getting around it but which one?What makes RCs worth twice as much as Accels?Ive heard some horror stories about the Accels,I dont want to do this twice,so I call the tuner everybody trusts and he tells me hes installed over 50 sets with no problems and since his word is golden,Accel it is.Now I call Summit to order a set and they havent got a clue and the guy tells me Accel doesnt make an injector for a ZR-1,plus I want a direct drop in with no mods.Ill call Accel tomorrow and get some info.Im not looking foward to this but it has to be done.How much of a hassle is it to get the cam covers off?

Re: Fuel Injectors
 

From the summit site, order 2 of 150821.

Re: Fuel Injectors
 

I've got accels with no problems

Re: Fuel Injectors
 

Why would you need to take the cam covers off?

Re: Fuel Injectors
 

:mrgreen: I smell a powder coating job coming!:sign10:

Re: Fuel Injectors
 

If you order the Accels from JeffVette and ask him *VERY* nicely, I'm sure he'll remove the tabs for the primaries.

Won'tcha Jeffie???
Specially since it sounds like he's sending his top end to you for a powercoating...

TomC

Re: Fuel Injectors
 

Thanks for the info on this Jeff.

Re: Fuel Injectors
 

First I wanted to say thanks to everyone who contributes their vast knowledge to this board. :worship:

I just replaced the injectors in my 1990 with the Accels from Atlantic Speed Performance Parts (and got my free shirt with each set.) Also from the recommendations I got scouring the boards I changed out my plug wires and fuel filter and reset the ECM. I am amazed at how much of a difference it made! My Z only has 35,000 on it so I felt like it was still pretty fresh - but now it jumps like new again!

Also, I spoke to Jeff at PNWZR trying to buy the injectors and Marc Haibeck trying to buy the illusive O rings for the primary injectors, and they both confirmed that there is no need - you just use the stock GMs that are in there already. Also both of those guys were very friendly and helpful. Thanks!

Re: Fuel Injectors
 

Hi ,
Thanks for your post. I am installing new injectors I got from Kurt White. Was not sure about which groove at the top of the injectors to use and then I remembered your post.

Re: Fuel Injectors
 

I have an opportunity to buy some injectors from a '93 ZR-1. I have a '91 that needs some injectors and am curious if the '93's will fit. Any comments on this?
Thanks

Re: Fuel Injectors
 

93's are 405 motors. 8 will fit, 8 will not.

Re: Fuel Injectors
 

They will fit fine (assuming you mean factory stuff from '93). However, since the '93 seals on the end, and the '90-92 seals around the body, you will need new o-rings for the injector housing. They are slighty bigger than stock because the '93 primary body is slightly narrower than the '90. Marc H sells them pretty reasonably, possibly others sell them as well.

I have '93+ injectors in my 1990.

You might also want to clean them up a little since now part of the body will be sticking into the sealed or clean side of things.

Re: Fuel Injectors
 

If any of you need O-rings - I have them - $1.50 / O-ring. I did a lot of research - They are Vitone rubber and are resistant to all of the bad things that make them go bad and have a fantastic temp. range. I learned my lesson when I tried to by them from GM and Kurt white - Kurt wanted $16.00 per oring and my local GM dealer wanted $20.00 - He was only able to find -(1). So I went looking on my own - did not want to let KW take unfair advantage of me. So if you are interested let me know - They are easy to drop in the US. MAil - You will need a Qty of 8.

I'm using a set I bought from Don. They are excellent!

Re: Fuel Injectors
 

I have read all eight pages of the fuel injector topic and did not see the answers to my questions:

1) What are the ratings for a '94...21#?, 22#?, 24#????
2) Are the primary and secondary ratings the the same?
3) If I go with the Accel's...mentioned in the posts...would I need the O-rings mentioned in the post?

Thanks

Re: Fuel Injectors
 

19lbs


Yes

No

Re: Fuel Injectors
 

I visited one of the suggested sources for fuel injectors...Atlantic Speed.com and the only LT5/ZR-1 injectors they list are 21#'s. They show the 19#'s for use on '93-97 LT-1's.

Are there any advantages or disadvantages using a 21# (Accel) instead of the recommended 19#'er?

Re: Fuel Injectors
 

BB,
I ordered sixteen of the #21's from Atlantic Speed for my 94 Z.

Re: Fuel Injectors
 

Have yours failed? I didn't think the '93+ injectors tended to have issues?

Re: Fuel Injectors
 

They have less issues, but will still fail from lack of use.

Re: Fuel Injectors
 

You are supposed to use the 21lb for the LT5. If you use the 19lb accels you will lean out the motor.

Order Accel 150821 cut off the alignment tab and remove the lower o-ring on the injecotr body for the primaries and install.

Re: Fuel Injectors
 

No failures yet, I'm a diesel man and you can't sleep easy unless you have a spare set of injectors handy just in case you run into some bad luck.
Plan to put them in this winter along with the P&P plenum and IHs.
