Well i have a HPI nitro mt and was wonderingwhich engine to put in it. The .18 engine only has 1.9 horsepower and the .27 has 3.1 horsepower which is a lot. I think if i go with the Trinity Sirio .27 Racer Monster Horsepower 27XL which will probably get the truck to go 70 MPH but if i install the 2-speed transmission then it would go 90 or even 100.
. But the other car i want to get is a scheumacer sst fussion which with the optional gears it can go 80+ which is great. An if you can't tell i an a speed freak always trying to get things to go the fastest and be the strongest at the same time. Or i would put a Rb concepts engine in the MT and with a RB innovations supercharger.
