Baby Holset Turbo Conversion build thread
Hello to all
Been delaying this project for a bit, and I've now started, better make a thread.
To summarise, I bought a 1978 300D a couple of years back. It was 4 speed NA, with a 1980 (dunno why) 617.912. About a year ago we swapped a 617.952 engine with a 5 speed 711.113 from a T1 van into it. Trouble is it burns oil like no tomorrow - probably just a seal gone in the turbo, but I've got better plans for that engine...
So, I'm going to swap the .912 back in. Marry it with the turbo exhaust manifold from the other engine, and attach a Holset HE200WG to it (thanks to Alcaid!). Idea being reasonable flow for a NA>turbo conversion. Rather small on the hot side helping to spool quick, and probably preventing me from blowing up the NA engine due to choking at high RPM Still, this turbo made 186hp on a 1.6 IDI VW.
I bought a cheap water/air intercooler on ebay which turned out to be enormous...going to use it with a radiator off a Renault.
With that is a 7.5mm M pump. It's a bit OTT for a formerly NA engine but it'll get swapped onto the .952 eventually. Looking at feeding it with a Bosch 044 pump (hate electrical things on an all mechanical diesel so will have to "work on that" ).
Seeing that I will have an excess of fuel, I thought I be best to install piston oil squirters too. Also looking at water injection to help keep things cool.
