hey guys im looking to buy some fuel injectors for my 94z28 does any one know what lbs are the stock fuel injectors???im looking to buy new ones stock replacements i was thinking some 24lbs from accell injectors are these injectors a good performance stock replacements???..any suggestions guys please..thanks

 

Stock injectors are great for well over 300 RWHP which you are well off of. I wouldn't spend the money right now. The only reason to change is because your require much more fuel ( cam, strocker, etc) or you have a dry N20 system.

You are exactly right, the stock injectors will hold up for anything you can throw at them for up to 350hp but they will still work for a 400hp application but you will run a little lean on the upper end. I would suggest keeping them in until you stroke it out or run a dry kit, but wet is better. So unless your stroking or fully modified with cam and heads dont do it. I have a 388 ci LT1 running on stock injectors and it runs alright but it needs atleast 50# injectors/255 fuel pump and a tune to run right but it is running on the stock injectors but it runs like crap. My car would run out of fuel on the dyno right now.

 

The stock size is #24 I would leave them alone unless you have problems. But i run SVO's that is what alot of peaple on hear run. Also do a search

 

sorry guys i forgot to mention that i need the injectors right now becuz i had my car on the scope today at work and it turns out my car needs 1 & 2 injectors so i want to replace all of them...whats the stock lbs for the stock injectors??.thanks

 

FMS injectors have served me well. Had a set of used 30# and now a new set of 42#. Work perfectly and the green ones look cool They're inexpensive and everywhere.

 

I have some good used SVO 24lb injectors for sale. Less than 4000 miles. Thanks, Ken

 

Get FMS/SVOs WAY too many bad experiances with Accels, just do a search here and see what I mean.

The are available in 24lbs but it is rated that at 39psi as opposed to our 43.5psi, the pcm will compensate for the small amount at part throttle but WOT will get richer so ideally you would tune for them but they will work without it.

 

Where Can I Buy Svo Injectors???thanks

 

Check any of the board "suppoting vendors" like T. Byrne, JEG's or Thunder Racing. They are very easy to find.

One thought... why not find two used stock injectors? The intake manifold was designed for the spray pattern of the stock injectors. They fit correctly between the stock rails and the intake holes. The retainer clip fits correctly. Its not the same as other types of injectors. It should be possible to find two good used injectors rather than a whole set of SVO's. Or send them out and have them checked and cleaned. The shops that do this will have replacements at low $$ if yours can not be restored to normal.

 

i'd buy bigger than needed now with expecting for more accomodations. you can always de-tune the injectors. and tuning the PCM will do wonders for the car any ways....i'd still go bigger than stock.

at least some 32-6lb injectors.

 

yeah i was thinking of buying two injectors from napa...just for now..
