I also could not view the technical information at the KIA site, but I suspect that a 2002 car will have a fuel system without a return line back to the gas tank. I recall Sport Compact Car superchargine a Miata about a year ago (possibly 2-yrs ago) and that car had no fuel return line. I know it made it more difficult to achieve added fuel under boost, and that a rising-rate fuel pressure regulator could not be used. The article did hint at what they did to overcome this problem. I would look for this article (maybe your library has the mag.).

Sorry for the links not working. I know what the major parts are that I need. It's just this stupid fuel thing that is stopping me. I don't even know for sure if it is a returnless fuel system. I believe it is.And, I'm not too sure that I will ever fing a SuperCharger that will fit under my hood. That could be cool though. I just don't really know what kind of fuel system I have here is a little tech info though. I'll just paste it here.

It looks like the FPR is built into the filter.Look at the diagram, the fuel line from the in tank pump runs to the filter and then back to the tank, it looks like the fuel line to the motor hooks to the filter next to the inlet from the tank. This is a guess on my part but thats what it looks like from that diagram. If that's the case you could run a different filter with only one inlet and one outlet, use your stock fuel line to the engine for a return line and run a new fuel line with a regulator and a FMU. Does this make sense to you?

that's what I was about to say.. My focus is "returnless " too, if I wanted to make it any faster, I just slap a zex wet kit on it.. But it breaks enough with nitrous or a turbo...

if i were you i would do a standalone and scrap the stock fuel system, or do some type of added injector system.

doing some sort of patchwork thing with the stock system would be too much of a hassle. (for me at least)

you should look at that supercharged miata article if you want to still use the stock fuel system. fuel systems for turbos and superchargers are basically the same, they just depend on boost.

also how much horsepower does this car have stock and how much does it weigh?

89dxhunchback

If it is tuned well, I see the tranny living about 2 months.. If its not tuned right I see the motor lasting 2 runs.. Not hating, but you gotta see it coming sometimes..

The best thing you could do is look for a additional injector controller SMC has some fairly cheap ones that work.
The thing about putting a turbo isn't the turbo itself, but the fuel delivery.
If I were you I would do the SMC and get a MSD BTM(igniton boost retard)
Good luck.
It will work though
