My current setup:
96 Maxima, 5MT, JWT ECU N/A Tune w/ 7500 Rev, Warpspeed Catless Y, Greddy SP2 Catback, PR Short Ram, MEVI (opens at 5200rpm).

Considering purchase:
V1 blower w/ bracket, 8:1 FMU, Vortech BOV, Walbro 255, 2.87 pulley (12psi?), and the usual goodies (oil lines, fittings, 4g charge pipes, bolts, belt, filter, thermostat housing)

Will I be able to run this safely as is, with my current setup? Will it be imperative to change the ECU? Will I need a different MAF? Any input is appreciated.

 

No, you will need to get rid of that ecu and get proper injectors for the boost level achieved from the 2.87 pulley. I would also recommened the Z32 MAF for that setup.

 

Could I simply use the appropriate pulley to attain 10psi, and keep the setup?

And if I use the 2.87 pulley, and get a z32 MAF and 300zxTT injectors.. what ECU should I use? Would stock be appropriate? Or would retuning the JWT be necessary?

 

In for enlightenment.

 

You could run the 10psi pulley(on my V1 I used the 3.0 pulley) with stock injectors and the FMU but they will be maxxed out and not really an ideal setup.
The JWT NA tune will not work for a boosted setup, the timing will be too aggresive.

You could keep the 2.87 pulley, upgrade the injectors, run a Z32 MAF (The Z32 MAF is recommended when making above the 300whp mark.) and then have JWT reflash the ECU for that setup and be done with it and have a relaible setup making decent power.
However running that setup wont yeild you the most power your capable of making.
To do that, you will need an adjustable engine management system and some time on the dyno for tunning. That is the real way to make the most power, and be somewhat safe. Just as long as the one doing the tunning knows what they are doing.

Also, get a Wide band, no matter what setup you plan on running it is a crucial part of any FIed setup.

 

**** the FMU off. Those things are useless. Bigger injectors and electronic tune ftmfw! seriously.....

And yes..you will need the Z32 MAF. Fixes heaps of issues. I'm running the 2.62" pulley with no issues now.

 

Thanks guys!
