I would like the TT ppl out there to review my plan here and give me the low down on what problems I will see and compare their notes to what I have heard about each part of the conversion as I listed them seperately to get more response and inspire experts on each issue to respond. Please write as much as you see fit to get all points across. Anything is appreciated and will be added to my compilation on the conversion for future Z owners

Fuel PressureNot a newbie, so I know there are differences between TT spec fuel pressure in the pump. If I run the TT spec injectors of 370cc in the N/A fuel pressure with my piggy back on the ECU will she be ok? I could buy an inline pump but my budget is running dry and if absolutely necessary I will buy it. but I hear it isn't a HUGE deal and shouldn't lack fuel as long as it is just the TT spec 370cc, am I wrong? If necessary how many psi should the inline pump be min and max?

ECU PiggyBackI have a V-AFC, "thats only for V-techs" I know I will hear, but wrong Apexi service told me its like the SAFC they have, only it has cam extras for V-Techs which you can just, wow get this, not hook up... lol It comes cheaper as most people have this misconception that it is v-tech specific and can be a steal compared to the S-AFC which everyone else looks for. Now I know there are JWT upgrades and chips galore for timing advancement n such but I don't want to adjust that because of my NOS section, feel free to peak and sigh heavily in dissapointment I guess. I hear you have to upgrade your ECU to compensate for upgrades. My plan as I have read around is, adjust air fuel ratios with the Apexi VAFC, monitor the ratios with a good gauge and I should be ok with turbos. This is kind of a gray area, so please weigh in on the specific diffrerences of an N/A and TT ecu. I already know the deal of boost control solenoids between them, but as you see I have boost controllers, so leave that gripe out. I also have acknowledged the fuel ratio differences as well.

This is what I'm planning to do so far, but I would like any WARNINGS, compliments, or suggestions to guide me one way or the other on anything I mentioned.

Anyone doing a conversion with an N/A engine especially or a swap complete, contact me, I would like to hear more from you...
