i dont know if u need an adaptor plate, i thought it bolted up, but i have a spare ct-26 layin around, but it needs a rebuild bad, i bet u would benifit from a larger intake and exhaust and use the afm housing off a 5mge supra, they are bigger than the 22re and 7mge's but use your chip board in the bigger housing and if needed, u can turn the afm up a couple of clicks to richen up ther fuel for the added boost
