veilsideS14

I'm trying to piece together where and for how much I can get the parts needed to put my turbo KA system together and would like some help from y'all.  Who makes good FMU's, fuel rails, and fuel pumps for the S14?  I know that JWT makes good fuel rails but I does anyone out there know if they have any competitors in the market?  Also, where can I get a good high flow fuel pump (i.e. Walbro) and FMU?  Thanks a bunch for all the help!

I've been doing the same kind of research and so far what I've found, the best bang-for-the-buck upgraded fuel system is a Z32 fuel pump, with 370cc fuel injectors with a JWT programmed for such... the FMU is an ok idea since it's boost controlled (it adds fuel pressure under boost, the more boost, the more pressure), but according to Corky Bell (author of Maximum Boost and known turbocharging expert) he doesn't really recommend FMUs, he refers to it as a "band aid".

But I guess if you're not expecting to boost over 6-7 psi, the FMU should be OK...  

Oh yeah, and I'd go with the Vortech FMU, the XS kit comes with it, and remember Vortech has been working with forced induction forever.

I use the pump from a z32tt it will support up to 600hp
but let me warm you, it a lot louder than the stock one
