ID injectors + greddy
Hey guys I have been searching for weeks now and I can't get it straight....I have the greddy intake manifold, greddy fuel rail, and Injector dynamics 1000cc injectors and I can not figure out how to get them to fit correctly....I have tried several different ways of putting them in and I have tried different o-rings...every time the injectors get pushed too far down so the o-ring goes completely into the manifold and I have to fish them out of my head...so if anyone has installed these injectors with this manifold I would definitely appreciate your help and pics if you have any...thanks

Being that they are pencil style, you can actually weld metal bushings into the manifold, that then have the same bore as the injector o rings...I've seen them on here, but I'd hafta search for them again. Shouldn't be that hard to make though either if you have the ability.
On my car, I actually had a plated welded atop my rubber bushings, and the body sealed in the large gromets themselves.

Well I thought I had my injector problems sorted out (I have the greddy mani and injector dynamics id1000s) and the greddy rail.
This thread is making me think my fix isnt going to fix it all though. What exactly is the point of the top plate? |

This pic is more recent, still not a good shot: This pic is from FOREVER ago...heck I didn't even have my VC back from powdercoat yet LOL! Quote:
So I came up with that solution with that upper plate. It's remvoable as well in case the rubber o ring goes bad or whatnot too.

Ahhh. That makes sense. I have the OG greddy mani without the mounting points for the new greddy rail, which would have been nice if they would have this advertised about their rail..... When I called greddy about this we had a "nice" conversation where they told me I shouldnt have bought a fake manifold and I told them it was real (real real expensive back then too) and they didnt want to hear it...... Couple hours later I get called back saying that there was a design change soon after they came out with the manifold to mount their rail on. I was hoping they would exchange my manifold out even if it cost me some and they offered to sell me one for retail.
ANYWAYS So I had to make an adapter to mount the rail and I had to modify the spacers on the rail so it would sit low enough, but something always seemed to be missing. I dont plan on running the small orings at the tips as they are not sealing to anything and just seem to pose a hazzard as they can come off. Anyways something just seemed to be wrong still. I never thought about the big seals pushing past the injectors under boost though. I guess them fat bodied injectors do have an advantage. |

See on those injectors it has that little plastic keeper sort to speak, so that may work out for you just fine. On the Seimens/Deka/Mototron 60lbers that I have, it's a smooth injector.

Yeah I am pretty sure the same thing will happen with the stock manifold....the washers seem to be working but I won't know for sure until I get the car out of the body shop and do a boost leak test on it....

Yeah I had to drill them out...I used a step up bit and went to 9/16....its the closest to the size of the injectors you can get with bit in the ft/lb/s (American) system....it is a little big but I think it will work fine

Leaky Injector
|
Is there a way to use top feed on the stock manifold? Only thing I've read about so far was using something like Mazworx's spacer. But haven't really read too much reviews on that.

Go search for a post I made about getting top feed injectors (like yours) to fit greddy manifold. Although its an Rb, the solution I found using a companies spacer could be your answer. And you won't have to worry about any leaks etc.
