Received the engine today and proceeded to transplant the single turbo over from the blown motor. I then realise the blown motor is equipped with stock injectors instead of upgraded injectors as the seller represented. Remedies against him aside, I need to make a decision quick on what injectors I should upgrade to. I want the stock motor to last a bit and have no intention of going over 1 bar. I'll be dumping the RE ECU and run a PFC with Dataloggit. The car's got a secondary Bosch fuel pump and fuel regulator so it looks like the scum just took the injectors out. Injector combination that I'm considering now includes:

(i) 4 x 850cc
(ii) Stock primary + 2 x 1,600cc
(iii) 2x850cc primary + 2 x 1,600cc

This is very unexpected and I need to make a decision within today as my car's occupying a friend's garage which he needs back urgent. Your comments would be greatly appreciated.

While at it, does anyone recognise what year/model does the following rats nest come from?

The td06 25g is going to get you in the mid 400hp range. Just run the stock primary's and the 1600 secondarys with the pfc. You'll have all the fuel you need.

Thanks Destin. Any clue on why the rats nest from the motor looks like the above? It looks like an improved design and I've got this on both my blown motor and new motor. My previous RX7 has the same conventional and what appeared to be the older design (i.e exposed solenoids on metal rack). To my amazement, I also found that there are at least 3 types of stock intake manifolds with different pipings and attachments on the underside. Wonder why mazda is making so many variant for the same engine?
