I have a 1982 crossfire corvette. Can anyone tell me how to ID the lbs of the injectors?

I once found a chart that showed all injector sizes but cannot locate.

Any help will be appreciated.

Thanks
 
I THINK 5oh motorsports had a site that rated all those things....

very large dealer in injectors....
 
- You can identify the injectors you have from the numbers stamped on them
There is a part number and a date stamped on the top of the injector.
Part number format: GM523xxxx*RPD, where RPD = Rochester Products Devision, xxxx is dependant of injector size and application (see table)
- Date format: xyyz, where x = month, yy = day, z = year (1=January, 2=Ferbruary, 3=March, 4=April, 5=Mai, 6=June, 7=July, 8=August, 9=September, O=October, N=Novermber, D=December) .
For example: 8202 = August 20th, 1982

Hey Guys.

I'm starting a new injector business. I am finalizing the details as we speak. I will provide lifetime warrantee on all reman injectors. I can do custom injector sizes if you need it. I will have new injectors. I can do marine injectors, import injectors, harley injectors, and special application injectors. Any size, any application.

All injector sets will be flow matched and warranted as long as you own the car.

Prices will be practically wholesale, as I am selling to auto parts houses at the same price I can sell to you guys for.

I'm sick of working for people, I don't take direction well, can you believe it.

I feel a bit like a whore here, doing this, but if you need injectors, I can be temped to do first set free to see how you like them. The remans come out like new not like they came out of a junkyard.

I am tying up the loose ends, finishing up the website, and will be on line in the next couple weeks.

To the OP if you want to send me your existing injectors, I'll rebuild them N/C so you can be the first to try them out. Makes me feel like less of a whore.

Thanks

Jsup, if you serious, I have some 4 sets of 21-24 lbs injectors to fit my lt1/L98 induction....

I have a rough idle that has been put off for a while now....since the fuel issues...

so I will send you all the injectors for a set of good 24 's.....

maybe 26? if you can find them....but my computer is tuned for the ever popular 24's....dunno if that old computer can keep up with the new ones...course I could trim the FP down a tad...I suppose...

I even pay postage...both ways...

Tell you what Gene, a full set of 24s with a lifetime warrantee is $189. I don't really need the cores, but I'll take them. I'll send you a set of rebuilt 24s flow matched and rebuilt, free. If you want a CUSTOM flow rate, of 26 say, I'll do it for $100, for all 8. It's time and labor. 24s are off the shelf. Because they are custom, they are harder to flow match exactly. Just so you know. But you will get a flow sheet.

What I ask in return is for your HONEST opinion of the quality of the work that goes into these and your impressions of the product, and that you tell all your friends. I'm not commercially up just yet, but by the time your review is ready, I'll be really close. I put a lot of time and effort into this and I am confident of the quality of the product.

You send me $25 for shipping, and we're even. How's that?

Hope I'm not whoring here.

You let me know.

To the OP, I'll rebuild both those injectors for shipping costs. There's only 2 injectors on a cross fire if I remember correctly.

Let me know.

somehow I sure you maybe able to use the cores....up to you...

I send PP or check, as you wish....no sweat....24's are easy do, leave over with it....good till 350 hp, apparently....good enough....

one of them nasty little details left over to the fuel problems....I guarantee one thing, that the tank will be sanitary and dry again, before they get installed....and taking glass full of fuel to see if it's really gas and not 1/2 water as in the past.....I dunno you been following some of my escapades over the last 5? years now with this shit, but I"m getting paranoid....

so much so, I"m tempted to install a water separator system like used for a air compressor on the SUCK side of the fuel pump, which is frame mounted...and take out the water/ethanol/what EVER ....

NOT a issue at this point....we talking and I fully aware of many issues with idle quality, and water/fuel problems over the years.....

I know full well what to look for NOW...instantly...no more of that dummy approach....
