Transplant M18 into HT81S the Russian Way

A casual browsing today bump me into this page in Russian by an owner of HT81S. He had picture out the process of him getting a M18 engine into a HT81S. Mostly the words are in Russian so I don't understand much, but with google translate we can read and understand a bit of the question and rant he have in the process. The photo are great and a good source of reading.

I do appreciate if the original writer could share what is the current status of progress of this mod. Really interested to ask about the electrical and mechanical parts.

  2. i had the M18 inplanted...it is a very simple job for the workshop as everything is just plug and play...performance wise is more on torque and not hp...i dynoed a 125hp which is somewhat the same as a M16A. however peak power came at 5000rpm. which is 2000 earlier than a M16A with peak torque at 5500rpm. The M18A is build for more torque...to get hp...will need to change more aggressive cams and lighten up the piston, strengthen the conrods and rev higher!
