I'm no longer holding my breath for a Turbo/EFI from Hyper Tech. I can't get a hold of them. GP Engineering has done nothing with the DS. They are at Pikes Peak with Turbo Banshees right now. Unless a DS owner can get a hold of these people and persuade them to offer some DS650 kits, it may never happen.

 

your giving up too easy. if you want it build it. all after market parts are built by someone. as far as i can tell i have not found a ds as built as mine. and you can't beleve how many times i've been told you can't do that. the only people i have been beat by are over built side pipe banshees' who have to change there plugs every third pass.... there are lots of turbo co. out there. the only way i know to run efi is with a closed loop system and cal-map software. this system will increse fuel when boost go's up.(cal-map software is around $1500.00 alone) if you run a carb. use an electric pump that will put out 12-15 psi. get a holley fuel regulator drill and tap the top 1/16 pipe install vac. hose fitting drill intake same. run vac. hose from reg. to man. this will give you boost ref. we need more built ds's.
