so i have always been a D series guy up until last month when i came across my 92 hatch with a gsr swap for 3500 dollars..great deal. anyways i noticed the engine was sluggish between 3k and 5k on the rpm curve. with a little research i found out that the IAB valve isn't hooked up. then i decided i would wire it myself and i've been reading you need a p28 or p72 ecu and i have a p61 which is very rare but i dont know if or where i can plug my IAB's into? can anyone help?
