Heres the deal, I have an 89 CRX HF. prefect shape. I want more power and willing to scarifice some MPG for the power. I have been researching and talking to a few tuners that said the easiest and cheapest swap would be the D16A6 and keep the HF tranny for the better gas mileage. I dont plan on racing or anything, just when I feel like slammin on the gas, I wanna go somewhere unlike the car' current status when the AC is on (I live in the dang AZ Desert) to downshift to 3rd from 5th to go anywhere. Help me out guys. Budget is tight, but will spend enough to get the job done.
