Hi.
I have a Corvette 1990. L98 (not modified).

I'am about to replace my original injectors and i would appreciate
a second opinion on theese:

Dude,
Save your money. Look at a set of Ford SVO injectors (Jegs or Summit)if you have to have new ones. You can also look for a set you used LT1 injectors on ebay or www.LT1intake.com and then send them to Rich at Cruzin Performance for cleaning. All told both ways will cost about the same ($200 to $240).

BTW places like Ecklers are just overpriced.

Hope this helps.

The ones pictured appear to be the Ford/SVO 24# injectors...just with a higher price tag.

As said above, Summit Racing has them for cheaper. Thunder Racing (sponsor of this extremely helpful board) may have them as well...check www.thunderracing.com for info.

 

Ok. Thanks for the tip!

How about theese Accel:
110-150824 24 lbs/hr (8-pack)


I'am a bit unsure about the flow (24 lbs).
My engine is not yet modified. Can i use this "size" of injector in my original L98 anyway?

I prefer not ending up with a burned catalytic converter

 

Your L98 in Your Y-body probably already has 24lb/hr injectors from the factory. Stay with that rate unless you recalibrate the prom.

 

There was at least one horror story with the early Accel injectors, back when they first came out. I'm running the Ford SVO 24# myself, but I had to change the injector flow rate constant in my chip to 25.9# before the engine was happy w/ them.

The Accels are rated at 43.5psi, same basic range your stock fuel pressure is set to, but your factory injectors are 22#. Accel makes a 21#, 23#, and 24# last time I checked...and they specified the 21# injectors as TPI replacements.

If you want to buy a custom chip from Ed Wright, or get into PROM tuning, the 24# are a good investment. Otherwise stick with stock rate for best results.

 

If you want to get the bigger injectors now so you have room to do mods later, then go for it. Just get an adjustable furl pressure regulator too. You'll already have everything apart, so the labor won't be anything. Then just turn the fuel pressure down a little. A 4 psi drop in fuel pressure is about the equivalence of 1 lb/hr in the injector rating. Put in the 24 lb injectors and set your fuel pressure around 38 psi. You won't need to mess with burning a custom prom then.

 

I'm using the new Accel injectors, and they seem to be working fine. I've only got about 5K miles on them so far though.

 

Go with the SVO #24, I've heard horror stories about accels.......

 

I've been using the accel 30lb/hr injectors with no problem so far. And I think the price is right on them.

 

Gee. Thanks for the help

i'am a bit confused here, since my engine runs
porly as it is right now, i need to be quite certain that i'am buying injectors corresponding the original flow without being ruined.

Kind'a hard tuning it in when i'am not 100% certain that the
injectors is what giving my Vette a hard time

And one more thing, thoose Ford injectors everybody is talking about, do they have the same connectors as my originals?

 

I've downloaded this program WinBin.
Is this program any thing you Pro's recommend?

PS.
Having a hard time finding a suitable ecu-file for my ride.

 

now i belive tpis states that a smaller injector but more psi would be better for better fuel burn although the injectors would work harder but in return your performance gain should be better as well now it just depends on your mods and how you plan on going about it for injector size.

 

I think i'll go for det #24 Ford Injectors and change my flow-rate constant. If i just could find a ecu-file that works for my car's binfile. I've downloaded a ecu-file from http://www.eecis.udel.edu/~davis/z28/
but when i read my flow rate constant with winbin it just says:
"."
