Re: Portholes
No reason to pay a professional. I think Tuna's DIY instructions are dead on. Stick with round or oval for that "ghetto Buick" look. They also are rated at 5 more hp than diamond. Of course, if you turn the diamond sideways they become squares, and then the hp gain is the same. We always recommend fuzzy dice and a Pep Boys fart-can exhaust to complete the upgrade. Maybe a leapord skin seat cover from Walmart. You will turn heads....and stomaches. Have fun and thanks for the chuckles.
