Ok, to make a long story as short as possible my car (97 SC300 5speed) was recently in the shop getting a boostlogic turbo kit installed. Everything was cool and then after the dyno we took it on a few street runs. At first it was good, but then with the next few street runs it would go all the way down to 0rpm when coming down out of boost and stall out. We tried adjusting engine parameters on the AEM EMS, but it didn't help. We experimented with unplugging the idle control valve(ICV) and setting the idle on the EMS and it worked just fine coming off of boost. Since I know my ICV is bad I want to replace it but here's my dilemma. It's $515 at Lexus but I can get it a lot cheaper from toyota for the NA Supra (only $295). Is it the same exact part. I know so many things are directly interchangeable but I'm not sure about this particular part. I need to take the car back to the shop on Saturday for a few additions and a retune so I need the ICV by Friday meaning I have to order it ASAP. Any help would be greatly appreciated.

 

I am almost positive it is the same. almost.
