I wonder if it would be possible to put a 6.9 engine into a 126. It certainly fit into the 116 chassis. Another interesting car would be a 140 with a V12 or even better a V12 R-129 (lighter weight).

Might I make a suggestion? Your video is evidence of wreckless driving. Might be best not to put stuff like that online. Many states will revoke licenses on first time offenses of wreckless driving.
