Golf MK1 Cabrio + 1,8T Upgrade
Posted: Wed Sep 24, 2014 10:27 pm
Hello everybody,
i´m Jan from the north west of germany near the borderline to the netherlands.
My car (Project) is a MK1 Golf cabrio from 1993, i bought it without engine. Rebuild it complete at the technical side.
The first setup was:
1,8T AGU (everything stock inside)
K04-023 Turbo
Stock gearbox from the donor car (Golf MK4 GTI 150hp)
Complete harness of the MK4, everythin also light harness.
Install the ABS system of the MK4
Spec 3 clutch
H&R 50mm rebound coilover
Complete 3 inches Exhaust
Intercooler from a Mercedes Sprinter.
Get a file for the Bosch ME3.83 from a Tuner that was for the bigger Turbo and the Audi S3 injectors.
But the file was to hard and the engine had to early to much torque thereby one of the connection rods left the engine block
So that was a big damage!
Next step was a bit more work at the engine:
Zylinderhead was completly overhauled with RS4 valve springs and some more.
A new engine bolck get new pistons and IE connection rods with the result of 8,5:1 for more boost and more ignition angle.
The engine is now build for 500hp but with a small turbo.
It is an TTE upgrade K04-023 with the data of 300hp
And a new manifold
The Mercedes intercooler canged to a custom cooler from schweizer. (Not more than 10°C over outsidetemp at full load)
The gearbox get an Wavetrac locking differential.
The engine reached with stock ECU 312hp and 400NM
The mapping does a Tuner but after the first mapping i get the car back and was surprised that the EGT went to 1000°C and i tested not longer full load.
No wonder with an AFR of 14 at full load!
After some discussions with the tuner he believed me and the car goes a second time to him.
After the second mapping the car runs good at full load but partial load was not so fine.
For example the ACC enrichmet is too high and AFR goes to 10
After some more discussions i had enough!
And now i tune it by my self with the EMU
The EMU is a very great ECU and unbeatable price compared with other ECU on the market with the same features.
Now i´m at 1bar pressure and partial load is 100% better than before, everything is very smooth.
I have now a lot of functions and posibilities as with the Stock ECU.
I will give you some more pictures soon.
