warm up regulator part #needed

[carnutvic]

Hello I am new to this forum and just bought an 87 turbo.I have the dreaded dpo syndrome.My car is a mess.I knew that when i bought it but i did not realize the extent of the problems the car has.I have fixed alot of the problems already and now i am getting into the nitty gritty of fine tuning.The warm up regulator on my car is missing and in its place is an adjustable regulator.

Does anyone have the part # for the correct warm up regulator or a cross reference? please help.

Has anyone tried a different warm up regulator than the rare expensive hard to find one?

Here is what i have written down about the warm up regulator:

928S 4.7 litre (8 cyl)

79-83

Bosch K Jetronic

0 438 140 086

928.606.109.01

but it's identical to a volvo one as well. The warm up regulator, however, has nothing to do with you boosted fuel use... so, it's really just a warm up regulator... Some turbo-cars (not lotus) had warm up regulators that had a vacuum line from the intake plenum attached so as to increase fuel under boost but our does it via the frequency valve.
