R32 Rb20Det Injector Replacement

[Luke HCR32]

I'm currently in the middle of a turbo swap and am upgrading my injectors at the same time. I've purchased second hand cleaned/tested Denso 550s, they have the same impedance as the stock injectors.

I've already consulted this thread while attempting to get my stock injectors out:

However it is for the R33, obviously having side feed injectors and a different arrangements of hoses etc, all my searching has only produced guides on changing injectors in an RB26 or wiring GT-R injectors in a GTS-T.

My main problem is I cannot crack the allen bolts on my throttle body regardless of how much force I apply, seems silly to use allen bolts instead of hex bolts in such an important spot.

Is it essential to remove the throttle body? I've already removed and cleaned the AAC and all piping has already been removed due to the turbo swap.

Also I did not relieve the fuel pressure before I started work on the car, will this be a problem? Should I pull the fuse and run the car dry even though I currently have no exhaust manifold on the car? I would have to re-install the AAC to do so wouldn't I?

The fuel will just spray out no big deal as for throttle body removing it will make life a lot easier but it is possible to install injectors without removing tb make sure you put injectors in the rail before install as you may damage the o rings

Just pulled the injectors out of my 32 but i took off the top half of the manifold to get at the injectors and fuel rail, heaps of room now, also i suggest that you fit new injector seals while you have things apart
