im on the verge of picking up a rustler pro .15 from the forbidden e place. Is there anything i need to know about the rusty from what i can gather it is a very ordinary car but it will do im just looking into driving something new. I have a few questions
1. For a new engine to be mounted into the chassis what mod's need to be made if there is any?
2. What would be a good reasonably cheap engine to put into my soon to be rusty?
3. Is there any steel tranny gears for the rusty?
4. Would i be able to rpm everything on this rusty?

i have the rusty and comes with plastic shocks and plastic drivetrain like the output yokes the half shafts and plastic on the axles even with the old pro .15 engine you will have alot of problems with them in a few weeks the first thing i would buy for it would be mip cvd kit if you put a new engine the mods that need to be made is usually just cutting a few threads of the crank so the clutch nut can tighten up to the flywheel tight and a good cheap engine to put in it later would be a OS .15 they dont make any steel tranny gears for the rusty i dont know if you can full out rpm your car because i have never looked but i know they make a few things

ig you buy a 2.5 upgrade kit for mounting the 2.5, pretty much any engine would fit, i have one with the pro.15, and the 2.5 mounts are way diff then the 15 or any other engine

oh yeah one more thing, the pro.15 if you tune it correctly theres no need to buy a diff engine, it has good RPM ad alot of torque and speed

ok thanks everyone. I lost the auction outbid me shame on them. yea so ill jsut be putting a .18 cv-rx into my ultima insane power and speed but my poor poor poor tranny! lol ill tell you guys how it goes
