Hello guys, in advance I apologie for my english, I'm from Transilvania.
Last summer I have started a project: to swap the original 1.1 VW engine with a 1.3 G40 engine in my Trabant, and to make it turbocharged. In romania we don't have G40 experts and not even G40s, I barely found an engine donor (don't start throwing rocks, I didn took apart a good G40), so I need to rely only on online documentaton, so imagine how happy I was that I found this forum.
At first I would like to start with presenting my car: I'm working on it for la last 5 years. In this time i have changed the 4 speed gearbox for a 5 speed (code WW0 from a Golf1), servo brake, FK inoxline adjustable suspension, 50mm stainless steel exhaust, Opel Corsa Sport ventilated front disc brakes, and more others.
Now comes the hard part the swap. I have finished the exhaust manifold and the downpipe, I'm using a k03 turbo (the cold part and the midel part from a Skoda 1.8t, the hot part from an Audi). I have the original wiring form the G40, the stock engine, and I think the original gearbox. The questions ar the following:
1. What should I change in the wiring to make the conversion from the G-lader to the turbo?
2. I need to change the map sensor? I'm planing on running on 0.7-0.8bar boost at the beginning with the original chip, then go up to 1 bar when I can get a new chip.
3. For this configuration the original intercooler is enough or I need a biger?
Thx in advance for the help, and if you are interested I will keep you posted on the project.
In the pictures I use the original 1.1 engine as a dummy, it's easier.
