i'm working on an SOHC turbo setup...so far i have the following...

HKS Std BOVGarrett T3 Super 60Spearco FMICWalbro 255lph fuel pumpVortech 10:1 FMU

i only plan on running light boost, probably 7-8psi max...w/ this fmu are the stock injectors okay at this boost level? i plan on getting the jgstools manifold...what do i do about oil lines? do their oil line kits work for the ka? the Z31 downpipe flange is significantly larger than a standard t3, how did u guys get around this? the turbo compressor outlet is only 2" in dia. and the compressor inlet is only 2.75" where do i get silicone couplers that adapt from 2" to 2.5" and from 2.75 to 3.00? thanks for the help guys
