my boosting project underway!

[Backfire32]

Yeah i decide tonight was the night to begin and everything is almost done! except i had a few questions for you turbo guys out there..

1. how excatly and what tool did u use to widen the plastic and rubber ring on the intake manifold where the new dsm 450cc injectors go to make them fit in?

2. what would be the best place to run my vaccum line off my bov for the best response?

3. what size pipe did you use to the cat. i was going to go 2 1/2 in off the turbo to the bottom of the car and cut off right before the flex pipe on the stock downpipe i had and weld it to that but will this cause problems with flow going 2 1/2 to small ass factory piping or is it not that big off difference? i was thinking it would save some money plus let me disconnect the cat and run a test pipe.

i would appericate any info to these questions! thanx

I used a air drill on the orings. tee off the intake manifold. there should be extra outlets if you need them. I used 2 in pipe. everyone is going turbo

don't do anything with the o rings. its a myth that they need to be widened to fit. just grease them up with vaseline or grease, and put them in. they will be a little tight, so use a pry bar on top of the fuel rail.

or you could just widen them. I would feel uncomfortable forcing the injectors into the hole

[WiKKeDV16]

why.. if u have to force them in.. the seal is tighter than a virgens ass.. we did this.. this past weekend.. NO LEAKS.. what-so-ever.. .. hehe.. some may widen it.. but thats just a waste of time IMO and seans.. ahahha

yeah, but you're a fucking idiot. i'd feel uncomfortable modifing a car if i were you

[90_accord_dx]

wow that was a mean reply, lol... i think i might jus widen them a LITTLE bit.. then lube her up and slide her on in (then injectors into the o rings i ment) LOL

[Backfire32]

wow! you still have to widen the hard plastic rings tho for it to let the injector sit farther in the manifold i suppose but i will try leaving the o rings the same. so it really doesnt matter were to run the vaccum line off the bov on the manifold? i just thought there might be a better port off the manifold for it to react quicker. thanx for the help.

[WiKKeDV16]

if u wanna get technical... the farther away from the head the injectors are.. the better atomization..

[Backfire32]

so i guess the back part of the manifold away from the tb toward the fire wall would be a great place. thanx wik!

are you boosted?? don't tell me what i have to do, i've boosted about 3-4 cars now with dsm 450's, and i've never widened the injector seals that sit inside the intake manifold. those rings are rubber as well

[WiKKeDV16]

i was talking about the injectors backfire.. the further away from the head the better they atomize

[Backfire32]

really ? well mine has 2 sets of rings the bottom ones are plastic while the top ones are rubber. thats wired cause the plastic rings will not let you force into them i tried but the top rubber ones will. or am i suppose to leave the plastic ones alone? but if i do that there will be a gap between the rubber seal and the plastic one.

"o and wik, i like to get really percise cause i want everything on my car to be top notch!"

[Backfire32]

o ic, so it would be better for there to be a gap between the plastic rings and the rubber?

[Backfire32]

do you have a pic of how your injectors seat into the manifold?
