For starters there was no such thing as a AE82 SX. They were AE82 Twin Cam 16's. Seeing as the engine is different, even the stock ones, and I'm pretty sure the exhaust sensor is placed differently that the extractors wouldn't fit. Besides this you should have a larger exhaust for forced induction anyway. Under the cars they are different. I assume you mean the exhaust set up. Everything on the AE92 ( If you mean the seca it's a AE93 )is much neater than the AE82. I should know I've owned both a Twin Cam seca and a SX seca.
