Although its AWD and I have heard you cant just throw any motor in there as it may overheat so please suggestions on what to put in it to make it hella sick.
Overheating happens when the car is over geared, with respect to motor.
Generally speaking, you would gear the following motors as follows:
fdr = final drive ratio
17.5 around 3.8-4.0 fdr
13.5 around 4.5
10.5 around 5.0
8.5 around 6.0
4.5 around 7.0
final drive ratio is spur gear divided by pinion gear x internal ratio..
so a TT02 has an internal ratio of 2.6, so if you run a 86 spur and 25 pinion, you’re looking at
86/25 = 3.44; x 2.6, 8.944.. so you could run a very hot motor with this gearing and it would not over heat.
as a precaution it is recommended that you check the temp regardless after every run.
Now I personally don’t recommend any motor faster than a 13.5 in the TT02.
