[Vwdiesel] pump id

[raymond]

hi all, while reviewing an engine i had picked up though never investigated. it occurred to me that i am not sure of the ip that i am looking at. while it is a 1.6 na engine, it has a pump with a rectangular (space ship) diaphragm thing on top. the type that i have seen used on turbo engines. is there a site i can reference the model number. also, i would like to id the engine type. like i said it is a 1.6 though a perspective buyer was curious at to whether it was a hydraulic head. the number on the block is cr833966. wiki says it is an early 80's engine which came out of a caddy though this was a world wide use and listed years not present for the us market. 
fyi i am looking to buy a k14 turbo for my back up engine. wiki also suggested this motor used a garret turbo though did not list a part number. so i am wondering if the list finds one of these turbos to perform better on the 1.6. i do have yet a second td motor with a slightly bigger turbo. while this motor may be a good back up, it has not run in several years it will start though runs at high rpm and so i shut it down quickly. i am running a cleansing mix of fuel in hopes that it willcure this condition. 
just sorting out some parts and cleaning the shop a bit. i am in chicago if anyone might be interested in a running na motor.
