I have an 88 ranger with a 2.3EFI, 2WD, A4LD trans, that I am tinkering with. I runs fine and I have no problems with it. I would just like to get more power out of it. I installed a K&N filter to let breath a little easier. I have considered a header, a performance chip, high flow exhaust, installing an electric fan and removing the belt driven one, just to name a few thoughts. Could anyone let me know if they have tried any of these modifications and the results? Also any pitfalls that you have experienced. Is there anything that I have not mentioned that I could do? Thanks
