95 L sedan to 98 V4 JDM STi
buy a clip!!! you'll kick yourself after you've spent months finding parts you didn't know were needed. i needed random differential clips, new LSD half shafts form an 02 forester, custom rad brackets(JDM's were trash), rear disc swap parts, swaybar and mount kit for non swaybar equipped L sedan, RHD>LHD wiring lengthening, and custom heater setup running the 95 blower, etc off the 98 controls......... yeah, you read that right, custom a/c grafting, custom power steering line grafting...... other stuff i can't recall!
always prepare $$ wise. if you think it's going to run you $500 for a part, plan on doubling that. time wise do the same thing, theres always parts you'll have to wait on, etc.
