Just curious which fuel injectors are preferred. i already have the bbk fuel pressure regulator an i upped my current stock injectors to 55 psi (stock was 35psi) i want bigger an newer injectors but which ones? accel? bosch? i tried lookin for other post on this subject but nothin i found was any help to me. how about 30lbs injectors? with 80% duty cycle or so? (my engine is a 355 with 10.5:1 compression tpi) any thought or ideas?

 

I'm not sure you need bigger injectors unless you've got heads, cam, and larger intake parts. If I were you I'd run a set of Bosch IIIs, proably 30lb/hr would be more than enough. You realize you'll have to have a custom tune if you change injector flowrate from stock.

At any rate, I'd call Jon Banner at Fuel Injector Connection. or hit up www.fuelinjectorconnection.com. Jon is a FANTASTIC guy, I just bought a set of Bosch IIIs from him and would again in a heartbeat. He truly puts customers #1. Do a search on this site and you'll be overwhelmed with good feedback about Jon.

 

for intake i just have a CAI stock plenum stock thorttle body wit the air foil thing an i do have a mild cam cant remember the specs but its pretty close to stock but lil bit more lift an duration with 112 lsa hydro roller cam, lifers, an rockers. stock l98 head but brand new with stonger valve springs i think it said 100lbs more then stock and 1.6 rockers all the way around. i dont have a tuner or chip tho but ill check out that site see wat i can find o it doesnt have to be 30lbs i jus want bigger then the 22lbs an newer these injectors i have are from 87 so there old lol need updated

 

I completely agree that you should replace the old injectors but why do you think you need bigger than stock? There is NO reason to go bigger unless you need the fuel, and I highly doubt you need the extra fuel with that combo. Do yourself a favor and just get 22lb injectors and be done.

 

if everything is pretty much stock i tend to agree with 1MeanZ

 

i thought bigger would be better cuz im gettin in more air so y not more fuel? plus im up in colorado an the elevation im at is 5820 ft above sea level but if u think 22lbs an the fuel pressure regulator will be fine i guess i can try it

 

you are getting more air, but not that much. You're still well withing the range of the stock injectors. You're still running it on the stock tune even with engine mods, so if you want to improve something get the car tuned properly for your combo. Being at high elevation means less air so LESS fuel would be required....

 

alright i guess im ganna but stock injectors lol

 

what brand would be best tho? iv always been sceptical with Bosch so im hesitant on using Bosch

 

Stick with Bosch, you can get them almost anywhere

 

Bosch is widely accepted as one of the best there is. Put Bosch IIIs in it and be done....

 

out of curiosity, why are you skeptical with bosch?? It's one of the most efficient and reliable brands out there.

im skepitcal cuz jus i know the spark plugs are cruddy (experience) along with the mafs (read about bad reviews an lil experience [stock maf] ) so i figured it be the same deal with fuel injectors but thats why i wanted in-put on the brand subject

 

you will be very happy with the bosch injectors...it is a great product.

 

o real quick what about nos an fuel at my altitude? i have a 35 dry shot sneaky pete system but i plan on goin to 100 shot in a few months

 

If you want to do something cheap find a set of ls1 injectors. you can find them for $50 all the time. They are 28lbs at 60psi. I made 375rwhp on a 355 with them.

 

i though of that but wit ls1 injectors you would have to change out the injector clips would you not? sense its ob1 to ob2 an i dont wanna cut an splice anything i dont have to

 

You can get adapters for that sort of thing…

 

why would he pay $50 for injectors that are used and who knows if they work properly. Also they wont fit without adapters that he'll have to buy and they are the wrong rating so he'll have to have a custom chip burned.

This is so simple guys. call up fuelinjectorconnection.com, or call up the guys at southbay and get a set of 22lb BoschIIIs and be done. For a measly $150 you get completely refurbished and flow tested injectors, adapters and all. Just bolt them in and you're done, no chip burning or any other messign around.

I JUST did this on my 91 TA and it was the best and easiest thing I could have done for the car. You don't even have to pull the runners, just pull the plenum. I took pix of how I did it and can post a writeup if needed.

then i guess ill check out the 22lbs throw them in call it good
