Grab Our Firm Apple Of A Power. We all want more, but is there ever enough? How is it that the CPA next door is content to clog up the carpool lane in a 50 hp Prius, but we think that our K24-powered CRX needs a 100 horse hit of squeeze to help spool the turbo? Do we really need to drive to the ramen noodle restaurant in a car that can run 10s, or fry the tires in fourth gear? If you are reading this, the answer is a simple one, a confident and sure "Hells yea!"
Ever since the first caveman drew a crude painting of an S13 with an SR20 swap on the walls of his pad, we have been reaching. And just like that caveman, sometimes we still struggle to turn our dreams into reality. Well that is what we are here for. So get out your iPhone, take a picture of your personal cave drawing, and email it to us at firstname.lastname@example.org. Or, if you have a question regarding carburetors, or how to make fire by rubbing two sticks together, you can hit us up at Super Street Magazine c/o Technical Support, 6420 Wilshire Blvd., Los Angeles, CA 90048, 'cause that is better than communicating via smoke signals, we guess (barely).
This month, Kenny Burton ponders the ice age questions of how to tweak his Z32 and wins a set of Invo tires from Nitto.
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.
Q I have read articles mentioning a wiring problem on the Nissan 240SX project. I believe the car is Jonny's. Anyway, I have a similar problem. If I drive my car for 45 minutes it will hold a charge for about 24 hours. I don't have a massive stereo or amps. I took the car to the dealer, bought a new battery, and had it checked by a wiring specialist. No one can find the problem. My 240 is a '93. Also, I think it's related (but no one else does), but sometimes when I turn the ignition key, even on a full charge, it does nothing. I have to turn the key two to three times before the ignition and starter engage. My question is, where or what caused your power drain? Can you give me an idea of who to see to get mine fixed? Thanks for the mag.

P.S. Keep up the great work. I have never seen better in coverage, girls, parts, girls, behind the scenes, girls, events, and girls.
A First of all, never believe a word Jonny says. He was probably leaving his dome light on all night, and then blaming it on a mysterious "wiring issue". Second, get a new ignition switch before you get left outside the club with a car that won't start, leaving your girlfriend to hitch a ride with some dude who has a reliable car! (Chicks do not see the adventure in having a car that only starts occasionally.) Anyway, checking for a voltage leak is pretty simple. First, remove the negative terminal from the battery, then, bridge the gap with a test light. (Either a commercial unit, or make one from flashlight bulb and some wire.) If you have a battery drain, it will light the bulb, and then you can get down to business. Start unplugging connectors and accessories, until the bulb goes out, and you have found your short. If you have any aftermarket or homemade wiring, that is the most likely the culprit. The faulty ignition switch is a possibility, as is a stuck or slightly shorted relay, like for the fan or starter.
Q I have an '85 Corolla SR-5 and I wanted to swap the engine with a 3S-GTE. Would it be better to buy the complete clip or just the engine? Torian GunnPhoenix, AZ
A We've always had a soft spot for these fun little cars, and are surprised that it took so long for the American market to really embrace them. All we needed was a little JDM influence in the form of drifting to make us realize how cool these cars were. The only bad part is that they were never that common to begin with, so now they are getting snapped up and used hard, making them rare, desirable, and more expensive to buy. Anyways, you have a good question, with a pretty simple answer, which is yes, getting a whole front clip is always a good idea if you can get one. The crossmember, fenders, and hood do a great job of protecting the engine and accessories on the long journey from Japan. In addition, you are pretty much assured that the ECU and wiring harness are going to be in pretty good shape, and that you will have a replacement for old, worn out parts on the current car, like the radiator, as well as the little things like fuses, clips, throttle linkages, and such.
