I can get this FP Regulator for 75 bucks. Will it work w/ an LO3?? Product discription says it's for Fuel Injected cars and is universal, but for multiport injection so I was unsure. Thanks in advance!

does not look like it would fit at all.

that wont work on your tbi setup. the used to be a write up around here that shows you how to turn your stock fpr into an adjustable one with one bolt and a tap/die set. save yourself $70 and do it yourself with a stock piece
