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 about your problems by writing to Super Street at firstname.lastname@example.org 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 isn’t foolproof, it is a 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 Man, the H23 is a horrible idea. Sure it has 0.1L more displacement, but aside from that it’s inferior to your current engine in every way. Unless you’re talking about the H23A VTEC motor, which we highly doubt you are, because they’re very expensive and you’d be better off building your current motor than buying one. So in a nutshell, keep the motor you’ve got, cram it full of aftermarket goodies and party on.
A Although Charles no longer works at Super Street, he was kind enough to take a break from his busy import-tuning schedule to answer this question: “The brake upgrade is great. I can’t comment on the pads yet because I haven’t tried any others on this setup and since it all happened at once, it’s hard to tell what effect the pads have. Overall the setup is pretty good, but I’ve yet to track it; with my lame skills on the street, though, I love the setup. I’ve had zero problems with the paint so far—I just wish I had used a little more clear-coat because now they need wax to really shine.” - CT
A Although the MK2 Supra isn’t the most popular car, there’s a very tightly-knit cult following for them. We recommend going to celicasupra.com and celica-gts.com, signing up for their message boards and reading as much as you can. There are a lot of people out there who have already mapped out the best ways to modify these cars, and you can learn a lot by reading what others have found works and what doesn’t.
