On a positive side you will learn every square inch of that car chasing each new issue . and become very very familiar with how each component effects the next.
a wide band afr gauge is a must you don't want to think its running great and have it be super lean. They run great when they are lean, Then not so good ... if you do eventually rebuild and replace everything fuel related . when you go to set it up you will be like wow it all makes sense and it works .
does your car have the three pipe fuel accumulator? if it has a small leak it will blead directly into your return, reducing fuel pressure and you wont know it. The easiest way to test it is remove and dry it out put a balloon on the bottom port and run some compressed air through the supply 100psi and use your finger to close off the outlet side the balloon should not inflate.
i saw this post yesterday and have been super busy lately and haven't driven my car in a few weeks. took the old girl to work this morning , The turbos sure like the cooler weather.
good luck keep us informed of your progress.

Thank you! I'll be replacing all of the fuel components! the only thing I know which the previous owner did was reline the fuel tank and clean it. Hoses are all OEM I'd imagine. The thing had original plugs in which were almost seized to the heads. Electrical has all been done, I almost pulled the trigger on a turbokraft IC kit as well to get rid of that ridiculous recirc system. That's next!
Yeah it's more I'm not kitted up space wise to drop/lower the engine. My garage isn't large sadly (sore subject). So I'll need to find a space/place I can do the work. I have spoken to a few friends who will most likely be able to help! I knew for the bargain price I paid for it that it would need some finessing! lucklily I've worked on many old cars/bikes for a fair amount of years so I'm not phased, more hamstrung by lack of space at the moment!
