banks is still in full production too.you can call right up and order a full kit,to any small part you want.just for thier latest waste gated turbo of course.no longer selling the discontinued one,or parts.though most parts might be the same anyway actually lol i dunno.
i bought a used waste gate sidewinder and called to order parts.very helpful and shipped 'em right out.
all over the net.yes they're sold directly from banks and on their site too.
pricey new though.2500-3k+ because the kit comes with the E40D trans command and full exhaust.
i asked banks on the phone if he'd sell minus those two parts and he said yes.however the price matched an online vendor selling the whole kit for about the same $ anyway........that's when i went used.
