2000+ Multec2 injector option (opinions please)

[grayman]

Concerning 2000+ model year V6 fbody fuel injector system:

ok, I know these are much more expensive than used gtp injecotrs but they are multec2 (pin style) rather than bosch. They are 'mini' rather than long so the fuel rail feet will have to be shortened. Other than the fuel rail modding the rest should be plug and play, right? They are 38# at 43psi so they have even a little more room at 50 psi. With shipping the cost of 6 injectors will be about $300. They are also new rather than used...(as opposed to buying some old gtp injectors) so it should take some potential problems out of the mix following install.

I am not sure if these have been covered here in detail before or if they were just ingored becuase of the price and the fact that they are still 'mini' type.
I really don't want to hack up my injector harnesses and if i did splice in bosch connecors i would have to buy an old harnes or buy new adapters ($60) and 'de modding' would be a PITA.

What do you think? Are they compatible other than the shorter length?

Any problems out of the normal as far as idle? (consider the 50psi of stock L36 fuel rail rather than 43 psi fuel rail of LS1)

here they are...

secondary question:
Can an pre 2000 fuel rail bolt on in place of the stock 2000+ fuel rail? I only have my 2001 car to look at. A pre 2000 fuel rail already sits lower on the intake manifold. I can keep my eye out for a parts car fuel rail if so.

you car has 50 PSI at idle after its warm?

mine only has about 43 PSI

idle should not be a problem lonag as you use hp Tuners

you need look at you fuel psi at idle and use the calculator in HP Tuners to figure out you new flow rate

EX:
38 @ 43 psi okay if you running 50 psi your goign to have about 40# flow (do have hpt in front of me) this is the value you want to use in you flow vs KPA box.....

to be really accuate you would want a fuel psi reading ae every step along this way the pcm knows exacly how much fuel is going in...

HOWEVER i have found in my tuning it "confuses" the PCM and i got much better WBO2 curves if i set every box the same aas the idle box,

having differnt flow rates made it hard to dial in the car beacuse the PE table change more in different blocks then others... :mad:

hptuners has not arrived yet. perhaps today it will get here.

yea, i say 50 psi at idle becuase that is the most average number. i never see as low as 43 like some people. very rarel 48. sometimes 51. as far as i know the sneder and gage are accurate. it responds perfectly to a 6/1 fmu.

thaks for the heads up on the flow rate calculations.

well get yuor WBO2 and drive out this way i can tune it for you..... im mean come one its only a 4-day drive :eek: ;) [img]tongue.gif[/img]

i am thinking a satelite camera phone connection with me on a back road and you at a desk.

going out to start the ls1 retainer swap. got a little time before work.
