You can use a variety of injectors on your car. If you are looking for plug-n-play style injectors I suggest finding a 89-91 Mazda RX-7 turbo with injector part # 195500-2020 (these are 550cc) and also a direct fit into the fuel rail with the correct connector.
If you can't find a turbo model the N/A model pn 195500-2010 is 460cc and the same drop in capability.
Neither of these injectors will run well with the stock ECU, you will need at least an S-AFC to adjust for proper use. Stock GTX injectors are 330cc so the 460's are a good upgrade, I believe I maxed the 330's out at around 9-10psi with no extra fuel pressure over stock.-Braden

Oh, its not broken, I'm taking the chance while its out of the car to clean everything, polish the intake etc. I'm also having an adaptor plate made up to mount the turbo as we speak - its almost bigger than the engine and its got a weird bolt pattern. I think I'll need to brace it as well cos it appears to be too heavy for the manifold I'm also planning to get the injectors flow tested but who knows when I'll get around to that.....

Its a high-flowed t3/04e. Physically its a LOT bigger than the vj20. The bolt holes are a much bigger than the ones for the vj20 and there is just a lot more heavy metal, especially in the exhaust housing.
The adapter plate is a bit of an ass cos the turbo was originally off a 20b cosmo and they have a very weird bolt pattern.
All in all, it just looks way more solid than the manifold but I'm sure it'll be okay...I hope. I have been assured by the guy who rebuilt and high-flowed it that it will be good for close to 400 but I'm not going there, 320-340 is my goal for now.
