Question Of The Month
Q Hey Super Street, much love for Nads, Wong, Carter, and Rikdaddy. (Even though he's leaving your asses for his own endeavors. You never write... you never call...) I just got to say, I love your mag and have been blowing more money on it than $5 table dances at my local strip bar (must have the yellow fever).
The question is this. I own a '90 300ZX TT and I'm currently rebuilding the engine. I've poured a lot of money into this beast already with Wiseco forged pistons, JWT ECU, new water and oil pump, and timing belt. The turbo kit I'm using is Z1motorsports, GReddy 525R Kit. What I want to know is: With these parts, do I have to upgrade from my stock 370cc injectors? I'm a poor college student (the table dances are not helping) and have a pretty small budget left for this thing. Is it critical to upgrade to 555cc or what?
I have a GReddy Boost controller, so if I stay around 14psi, it won't run lean will it?
Also what's up with the Bosch's Platinum, Iridium Fusion plugs. Are they better than NGK's?
Let me know, and I'll put in a good word for you at my strip club. If your ever come to Texas, that is.

A Dude, we are so there! You should know that budget strip clubs are our greatest weakness here at Super Street! Even we are a little worried about the quality of a $5 lap dance though. If you are planning to keep the output close to stock, you can keep the stock injectors, but why go to all the trouble with the engine and turbo, and then limit yourself with fuel flow? The best idea for injectors is to always give yourself a little extra capacity, and let the throttle or turbo size limit your horsepower level. The reason being that if you run out of air, power levels off, but if you run out of fuel, KABOOM! And now you get to buy those pistons and rods all over again. (bet that would cut in on the lap dance budget)! So our answer is that yes, you can run the OE injectors , as long as you have the discipline to keep the boost reasonable, and maybe think about an FMU to boost the pressure a bit, but you are taking a risk for sure. We noticed that you did not mention anything about the rest of the fuel system, but you are going to need to upgrade the pump and lines, too, if you want to make serious power. Hit up Russ at RC Fuel Injection (www.rceng.com) and they will set you up.
