SuperCharger+NOS #5124 Kit
I'm buying the NOS 5124 Kit from a friend this week.
I also am getting Blueprinted 300zx TT Injectors very soon.
I already have a Cartech Adjustable FMU and an APEXi AFC I.
Running a 3.12" Pulley at 9PSI on the V1 SC right now. No detonation, no issues with fuel at the moment - tuned to 12.1:1 A/F Ratio across the board.
What else do I need to run this safely?
Do I NEED a JWT ECU?
Do I NEED the J&S Safeguard with this large of a pulley?
(I know Mardisgras swears by it, but he's like running off a .25"
pulley right now)
Basically I want to know what the minimum cost would be to get this to run safely. Later I will add larger components. If I have to wait until I can afford another $1200 in A/F stuff, then I accept that - but I want to hear opinions.
Also, what will I need to simply run the 300zx injectors without being super rich?
PS: I don't plan on ever running over a 30-shot.

You should be fine with that, but how many shot is this kit? If its 35 you should still be fine.
Mardis at the time was running around a 2.67 pulley. Way smaller than your current 3.125" It was near 14-15psi.

Fine without the J&S. If you are staying with the 9psi and shooting 35shot, as long as you tune it with either a Fields AFC or Apexi SAFC, you should be fine in not detonating. I think once you start running above 12-13psi, thats where the J&S comes into definete need/use.

Or will a SARD FPR do everything I need?

If you use the 2 together, your fp will shoot way over 100psi. You need enough "starting" fp to be able to account for the nitrous, but your ending fp cant be too high. Kind of a pain in the butt but its nice when tuned.

Maybe I'm misunderstanding you - but I was planning on having hte SC at boost and the Nitrous at the same time, after about 2800RPM. Not Nitrous then SC Boost.
Am I htinking about it wrong?
Jay - Yeah - you're right - I'll go with the Fields AFC.
I can't afford a JWT until after my wedding next spring, so that will have to wait awhile - but it will happen eventually. This going to cause any problems besides making it difficult ot tune?

Yeah - I may run that eventually - don't have the funds this year or the 1st half of next year (getting married).
So I'm tkaing it I can use a Fields AFC, Keep the Caartech FMU, get the 300z Injectors, and that's all I need?
(I'm a sucker for clarification - sorry guys)

I'll do that! (Especially since I already have a spot to mount it!)

OK so here is exactly what I'm going to do:
Install the 300zx Injectors
Install the AFC II
Install a Walbro Fuel Pump
Adjust the Cartech to ramp the FP under boost.
And that's ALL I need?!?
Also, can one use Water Injection with Nitrous??

It was issues like these along with Mardi's change of heart concerning the JWT ecu upgrade that led me to go the JWT ecu and Z32 mafs route for the 370 cc/min injectors. I'll be running a 3" pulley until I figure out what I'm going to do about charge air cooling.

I think the jury is still out about whether the JWT upgrade or a do-it-yourself system with adequate dyno tuning produces the most power (there is the opinion that JWT is too conservative when it comes to afr and timing), but from what I have been reading in other forums (nissanforums.com, for instance) I'm becoming convinced that the JWT ecu provides a safer and proven alternative with respect to detonation.

Well, basically, Matt talked to Jim Wolf and was persuaded that an ecu programmed by JWT for operation with 370 cc/min (or larger) injectors using stock fuel pressure is superior to cobbling together a system of fmu for coarse afr adjustment and safc (or other means) for fine adjustment of the afr, along with a lot of dyno tuning.

I've always been a JWT product fan, however the customer service hasn't been the greatest.

Funny thing was that they said now with the 550's, they have fuel for 350+whp safely.
Shouldn't they be good for 500+whp?

Another one with Blitz 550s and Z32 MAF...
'91 240 w/RB25DET + 100-shot NX:
Uses JDM EF-Sports modified ECU, Blitz 550cc injectors, Z32 MAF, and an Apexi S-AFC.
Says it puts down 350whp w/o N20.
