This is the project that I am referring to in the Robbomaz thread... It took the guy from Rostov (south of Russia) 2 years to complete and was way more expensive than the original S/C by Tone.
Just got installed a couple of days ago, needs some fine-tuning still, but he already runs out of 7 secs on 0-100km, even without adjustment for R20 tires..
The guy used to run on Alpine before and says the Rotrex gives much more power..
Here is the original 11-page thread... all in Russian, but some English names of the items used and some pix there.

p.s. his VX has like 250k miles on the clock, but looks better than 99% of VXs out there..
