Well if anyone saw my post “make it good or get a different one” they’ll know that although I did in fact decide to rebuild the rs4 2(go check out that thread) I also ended up buying an rs4 3, which I dropped a t3.0 I had into it, and that was fine, but of course I had to make it more stupid, so…
I decided to put a 3.4 in it! Probably my dumbest thing I’ve ever done with an rc car(actually now that I think about it it’s definitely not, but it’s still ridiculous) a .20 inside or a car meant for a .15, that makes perfect sense, to me at least.
The initial problem was, this was a big block(well small block formfactor but basically a big block) going into a side exhaust .15 platform. So exhaust was one of the first problems, which I solved by using a os .18tm header and a RB TM523 exhaust pipe(I’ll put a resonator in at some point, but I had this lying around so might as well use it)
That solved the exhaust problem, and as for fitting it, I’m not as proud of that solution… unlike the beautifuly done version by @fyrestormer(I think that’s his name? Look up 3.4 rs4 on google and you’ll find his form, he does great work) I basically took my old chassis and motor mounts, and just kinda.. crammed it forward, cut a unprofessional extra space to slide the engine where it needed to go, and it works!
I can’t say I’m proud. But this build was supposed to be a laugh for me,using stuff I already had so It’s not keeping me up at night. These pictures are the final product, I have some of its “pre development” stage that I’ll probably post, but for now I like it, it’s good enough for me, although I’ll probably throw something else in it, the .20 is definitely too much power, but I’ll just enjoy it for now.
Here was the initial build, with a linkage from a jato! Also where I stole the engine from(yes I had a jato 3.4) which as you can imagine, blew up transmissions way too much, I have a much more elagent throttle linkage setup now, along with better wheels and tires as seen in the main post
Here was the rebuild I did before the pictures at the top of this thread, this was a few days ago, and I cleaned everything up, also note the cheap spare tire I had on it and all of its wear!
