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, too. 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 your tech problems by writing to Super Street at email@example.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.
A If you’re looking into picking up a motor we do recommend picking it up locally so you can inspect it first. If you want to have a transmission that is worth three times what the engine is worth, then the B20/ITR trans is a good setup, but you’d be better off all-around to use the same money for a complete B16A swap.
A Hey Tim it sounds like you’ve got really good taste given the mods you’ve done so far. We find time and time again that KW’s line of coilovers offer the best balance of comfort on the street and performance on the track. That’s why we keep installing them on our own rides. As far as seats are concerned we’d recommend looking into reclining seats like Recaro Speed or Bride Cuga. As far as clutches are concerned most Nissan guys swear by the NISMO Copper Mix units and given their OEM quality we’d presume engagement should be excellent.
A To answer your first question, yes it could be a bad ECU, although it’s rare they do fail from time to time. However, your problem is too difficult to diagnose given the amount of information we have. We’d recommend taking the car to the dealer or a reputable mechanic shop as a professional should be able to diagnose the problem in less than hour. Once you know what’s wrong with the car you have the right to refuse repair and can do it yourself, you will have to pay a diagnostic fee though, but it beats sitting around scratching your head and scouring the Internet for bad info.
