Borescope arrives to check inside the T3 WBX racemotor
So, since the WBX race motor was built it never came up to expectations and I had a sudden question come to mind – it’s a 2.1l WBX motor and was originally a DJ code motor that has high compression (10.5:1) pistons in making 82kW – 112bhp DIN @ 4800RPM- this was a European only…

Fitting up external oil cooler for the Doka
The T3 double cab runs LPG and petrol, the LPG is half the price and makes less pollution than petrol so it runs on that all the time. LPG burns hotter (and slower) than benzine so the ignition is about 7 degrees advanced and the engine runs hotter – constant running over 110km (70mph) and…

Ratio Rockers for the T3 Doka
Learning how to cut to length cut-to-length pushrods Then the procomp billet 1.4 ratio rockers go into the #vwt3 #doka What could possibly go wrong ?

Laptop setup for the 02 sensor in the T3 Doka
Booted up a .Mac laptop in windows to reprogram the #innovatemotorsport wideband O2 sensor to display in lambda rather than AFR air fuel ratio – now it reads correctly whether I run the #vwt3 doka on lpg or benzine. Basically lambda 1.0 is stoichiometric – ie perfect fuel burn – irrespective of what fuel you…

Installing Wideband 02 in the T3 Doka
After new carb jets the #innovatemotorsports #mtx-l wideband and lambda sensor gets installed into the #vwt3 doka – will change the display from afr to lambda and it will meter both fuels without problem. Just need to find a windows laptop with a serial interface from somewhere to talk to the gauge?

Rejetting the T3 Doka
New upgraded primary and secondary jets installed into the NOS pierburg carb in the #vwt3 doka – it’s a 1.9 carb on a 2.1 motor so on lpg all is good but on benzine it’s super lean – going from 102/110 to 112.5/120 hopefully helps and a dyno session will dial it in

Fixing oil leaks on the T3 Doka
Addressing the oil leak that appears to come from the distributor on the #vwt3 doka double cab reveals the rubber oil seal is perished and so stiff it cracks when trying to remove it – new seal – slot back in – leak hopefully solved

Wiring for the wideband O2 sensor
Splicing cables together for @innovatemotors mtx wideband O2 sensor & gauge- but there are identical colour signal wires and can’t find multimeter to check – make diy continuity meter with battery & tiny motor :)wires are common – all fixed and sealed – next install in #vwt3 doka

New custom built rev counter for the T3 Doka
And now – in the #vwt3 doka – the new rev counter is installed, cabled and working ! From a gti it’s Mounted inside a custom 3D printed case with a new oem style face and peaks at a hopeful 7k rpm
