Hey guys, I'm planing on getting a new engine to replace my torq .21 (its kinda dead) and i was thinking about a .28 engine. I just dont know what engine would be good. I need one with good torqe becaus the Thunder Quake is a 15 pound car but I also want decent speed ( I have a 2-speed tranny). what do you guys think? i wont be able to respond right away but ill do my best, if you have any questions feel free to ask.

If it's torque you want in a heavy kit maybe try this

Wow that is a big engine, I like it, but the only thing it does not say is if its a roto carb or a slide (I need a slide carb) and if it is a roto can i just replace the carb with a different one that has a slide?

Yes, it's slide carb. Most big blocks are slide carb.

You do realize that going to a much more powerful engine than your stock .21 and you will more than likely end up needing to upgrade your drivetrain as well.  I learned this the hard way, lol.  But now I finally have a monster that is fast and just about bulletproof.

Also you will be losing some top speed with a bigger engine just an FYI they have less RPMs up top. but you can gear up to compensate.

My Drivetrain is a hefty so i dont think ill need to upgrade, i think this rc was made to have a bigger engine.

I'll look into some gearing but right now i just want this thing moving, the original engine is dead, all the parts inside are worn down and its discontinued.

You may gain some top end speed,  just because the engine is bigger doesnt nessarilly mean it will turn less rpms.  Many of the big block engines turn more rpms than the smallblock sport engines.  It just depends on the two engines you are comparing.  An Axial .28 would most certainly turn more rpms than your stock torq .21

the nitro way

an sh28 p8 is fine for ya not too big not to small very good power though
