BHG - - - there's nothing wrong with your car man, this is a completely normal condition... :sarcasm:
All kidding aside, I have a limited knowledge base about these guys, but from some searching I did on some local sites, Accelerated Performance is the ONLY place in Northern OH you want working on your Supra.
Russ and Don own the place together I believe, and before I bought my Supra I had a Russian friend who had abuilt 7MGTE MKIII and he raved about them and worked with them a bit on the side.... He went to UT for school but lived here in the Cleveland area w/parents some time back. We putted around quite a bit and worked on cars together (his MKIII and at the time my Subie)...
I sold the Subie eventually, and he rolled the MKIII; I developed major FAST CAR WITHDRAWAL SYNDROME and two weeks later found myself on the way to South Carolina to pick up my current 2JZ'd '88.
So I bought the car in a little bit of rough shape, and got in touch with Russ at Accelerated and he was going to be able to take my car in July to put in larger fuel injectors, Apexi NEO, power steering rack, etc etc.... Was nice guy, easy to deal with, gave me a quote... etc.
I never ended up going to have the work done because I decided to accomplish as much as possible on my own first, save some money, and get a larger 'chunk' of different stuff done next summer. But still they were eay to talk to and get ahold of and before even calling them I asked around the local forums quite a bit (toledotuners, etc) and Accelerated came constantly highly recommended as the guys to work on a Supra.
I think Don is the one who's into building 1000whp MKIV's, according to my old Russian buddy anyways.
So while I don't have experience with them working on my car, i've heard nothing but good stuff about them. And his prices quoted to me were fair as well.
I will get out there eventually, its just a long haul for me and I'll have to leave my car and go back to pick it up; just haven't been able to find the time to do that just yet. There are places around here like Sweitzer which is local to Northeast, OH area, I can't remember exaclty where, but he's EXPENSIVE and has started working on "wealthy" guy's Porshes and demands a cost for his work. Not even sure he does much with Supra's anyways.
On the other side, Accelerated was pretty busy when I called, was going to be about 1 - 1.5 months before they could get to my car. So if you're in a big hurry, maybe its not the place for you? 419-474-7170 if you're looking for their #.
Good luck with the repairs either way! Tell your wife not to a blow a head gasket over the whole situation... :biglaugh:
