Bought some Blitz 525cc injectors of greenline and spacers, Part # 31209, got a mechanic to try and fit them to my car but he couldnt get them to fit, said that the orings dont fit and there wouldnt be enough room for them and the fuel rail in between the manifold. So basicly paid $200 to get my old injectors pulled out and put back in. Can anybody help if you have fitted injectors to a r34 please.

Thanks

Brad

I just sent you the same info via PM

I took one of my old injectors and the new ones and the fuel rail to a mobile injector guy and got 12 new orings to suit, cost me $20 on a sunday. There was a 6 "green" thicker round orings and 6 black cyclinder shaped orings used.

You need to remove some of the smaller orings that come with them the blitz injectors

I have seen the blitz injectors on Yahoo japan for sale and come with additional orings

I had them in for approx 2000k's with no problems. I have since returned my car back to stock and sold them

No other mods needed. the plugs go staight on. no need to use the supplied plugs.

Fit the spacer between the manifold and fuel rail. I did need to use longer bolts

I had the same problem on an R33 S2. (I assume same fuel rail)

Swap the O-rings with the factory injector O-rings.

Once the O-rings are on you will notice a lip above the bottom O-ring (middle injector - purple top)

You can sort of see it in this picture attached.

You need to trim this lip back a little, a set of side cutter pliers will do.

The injectors should then fit, you do also need the blitz injector collers (which you said you bought).

Then you have the injector caps (hold the injector into the fuel rail) they have a little rubber piece underneath that you pull out

and then sits snug on top of the injector

They should sit the same as the stock injectors so shouldn't have a problem with clearance on the plenum top is

back on

If you have anymore questions just ask.

There is also a pic of the injectors installed in my car.

I SMS'd you a pick mate.

Thanks mate

Bah, leave the manifold in place you'll find it's a nice challenge......that's what I keep telling myself :)

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
