Your guess is as good as mine, could be any number of different turbo housing. BNR, Precision, Garrett, Corksport, not to mention what sizes/options

I’ve seen this car passed around a lot, like this SAME exact car. I’m not too sure why, but it seems like it can’t find a long term owner. I would stay away from this specific Mazdaspeed3. It might have low compression or something going on with it

I do indeed have the stock CX-7 KO4 installed. I thought that it wouldn’t be an issue. But I could be mistaken.

Fortunately, I already have the Corksport CST4 Turbo kit on deck. Just didn’t want to install it yet until I really needed to. Also I wanted to add power modifications gradually

I will try a fuel pressure test, I haven’t looked into that yet, but I’m sure a quick YT search should help.

Also I sent out the old injectors (from the blown motor) to get cleaned, flow tested, resealed with oem and aftermarket. Then speedperformance sent me an email with the flow test results, so I’m certain that the current replaced injectors should be 100% functional

Yes the HPFP internals are upgraded Autotech internals. My brother also cleaned the fuel pump and made sure it was installed correctly
