how comfortable are you doing custom work? if you want off road and 100mph here is what i would do.

losi 8t 2.0 Tekno brushless chassis and conversion kit with 44mm mount

losi 8b 2.0 buggy a-arms front and rear. put the buggy a-arms and CVDs on the truggy chassis so you have a very long but narrow and low off road car. (RCM member has done this)

also, you will need to run those GP rally 1/8 tires cuz buggy tires will just come apart. my losi brushless 8 2.0 clocked at 56mph and 3 sets of tires were destroyed just to hit that. both AKA and proline sets. 100mph is a lot tougher than you think just a heads up.

anyway, in the motor dept. i would run a Neu 1521 1.5d F on 6s lipo with 35c 5000mah rating. the MMM should be fine for the esc.

then for gearing take the 2 speed center diff from the inferno GT and mount the inferno gt center diff mount to your losi chassis. now you have a 2 spd. get the 2spd pinion from RCM with the tallest gearing possible and you should be good to go. even doing all this you will be very hard pressed to hit 100mph. youll have to make adjustments to the body or a custom body to avoid flight. also many other unforeseen challenges will occur i promise you.

i would probably even use the inferno gt shocks and mount them on the losi for super low cg. so all in all it wont really be off-road.

really what you are asking for is impossible. a 100mph speed runner on one hand and a daily backyard off road basher on the other?? aint gonna happen. even at the World RC Speed Record races where people dedicated to RC speed come from all over the world there are dozens that show up but you can count on one hand how many break 100mph. and that is in perfect conditions and a prefectly smooth drag strip.

but if i was going for 100mph what i mentioned above is how i would do it if i wanted to do it cheap and just try it. good luck!!
