We know how difficult it can be to work on cars; believe us, we’ve had more than our share of problems over the years. Good thing we’re willing to share this knowledge of problem solving with you and act like we know something technical about cars. Feel free to ask us about your tech problems by writing to Super Street at tech@superstreetonline.com or Super Street, Attn: Tech Support, 831 S. Douglas St., El Segundo, CA 90245. We’ll try out best to answer your questions but can’t answer every one we receive personally or in print, so if your issue is urgent, we highly recommend you seeking the help of a nearby mechanic! Also, try to do some basic research online; while the Internet and forums aren’t all foolproof, it is a very good start as there are many excellent resources to look at. If it helps to include a few photos to describe/illustrate your problem/project, please do so.
Crank, Slugs ‘N HarmonyQ
I hope you can help me with a problem I am having with my car. I have a 1988 Nissan 300ZX non-turbo that originally needed a fuel pump, then head gaskets, timing belt and now a harmonic balancer. A friend of mine said that if I change the harmonic balancer, I also have to change out the crankshaft as well. I find it hard to believe because I changed out a harmonic balancer on a ‘86 Mustang V6 and ‘90 Eighty-Eight. They never gave me any problems after. I actually had to buy the Mustang’s harmonic balancer off of a ‘90’s Cougar with the same size engine and had to grind it down to make it fit. This was back in 2006 and the Mustang is still running today.

You’re absolutely right Eric, so long as the balancer you’re installing was designed for your engine, you should be good to go. The only time you’d have to start worrying about re-balancing is if you stuffed the motor with lightweight internals or are using an aftermarket crank pulley.
Canistroke?
I have a ‘72 240Z I’m working on. Should I get a RB26 swap or should I stick to the L-series and stroke it? I think I would really enjoy a RB swap, but then again a stroker is pretty sweet. What do you think I should do?

This isn’t the easiest question to answer because there’s no right or wrong way to choose, it’s really up to the build you have envisioned. If you want to keep the car period correct, then stroking the L-series is the way to go (and the blown 3.1L S30 from Rocky Auto earlier in this book makes a damn good argument for stroking). However, stroking the L will be expensive, time consuming and more likely than not, end up making significantly less power than the RB would. Although the swap might seem daunting the difficulty level is nearly the same as building your old engine and cost will be similar too, but for outright performance and reliability you just can’t beat a newer engine.
Lexus Perplexus
I’ve got a ‘98 Lexus GS400 with the 1UZFE VVT-I in it. The only thing I’ve done is put some 18" BBS wheels on it and have just been daily driving it. I also have a 2JZ non-turbo (from a GS300, around 50k miles) just sitting at home (my brother rebuilds cars for a living) and I was wondering if I would get more reliable power modding the 1UZ or the 2JZ? I know stock that V8 is a monster but it’s common knowledge of what you can build out of the 2JZ. So I was wondering what your thoughts would be?

For starters there is a huge difference between the turbo and NA versions of the 2JZ. Sure, they have a few parts in common, but you should really consider them two entirely different engines. For the amount of work required to get a 2JZ into your car we wouldn’t bother unless it’s of the turbo variety. The 1UZ isn’t the easiest engine to modify and you’ll likely need to get custom if you want big power, but there are a few places making parts for these engines including transmission adapter plates for W55-58 and R154 transmissions should you want a clutch to play with. Take a look at lextreme.com, v-eight.com and clublexus.com for inspiration—and if you decide to ditch that 1UZ let us know; Sean is looking for one.
