I have a 93 R1 that was stock until recently. I have done the vacuum hose job, downpipe, air intake mod, full tokico adjustable suspension, RB sway bars, AST, and basic maintanance. I was thinking of changing to single turbo set up. Two questions came up...Am I devalueing the car by doing this (even if I keep original parts and I decide to sell)?....What other mods will I need to make? (I do have a Power FC and fuel pump to add). Thanks for your input. (I am the original owner and it currently has 48,00 miles

 

I don't think you have de-valued your car. You could always put the stock parts back on to sell the car. Then you could sell the aftermarket parts.
