Its all a sales pitch to be honest with you. I mean think about it if it was so much better they would have been doing it 20 years ago. And on top of that mitsu would have made them oem just like the make the stubby shafts to go on whatever engine they belong to from mitsu.

 

lets not forget that those long shaved balance shafts retain the plain bearing which runs at 2xRPM and is potential point of failure by itself... I too prefer the stubby..

 

Best kit to eliminate the bs is the oem stubby kit, least rotational mass, works as it should with no ill-effects such as the argument that the pump gears will push apart and wear into the casing.

Just gunna throw in my .02 on Team Stubby as well. Been running one in several different engines for years with no issues. 4G63, 4G69, and 4G64.

 

Not a good idea and 63 pully. I know you don't like the idea but Fluidamper is the better option.

 

This is minor but anyone have any issue with their downpipe rattling against the transfer case due to the manifold being 6mm higher or anyway to get the pipe down some? Or should I just wrap the downpipe to stop the sound.

 

Sounds like your missing a hanger on the downpipe. I know mine doesn't rattle at all and if it does I can't hear it anyways lol.

 

No hanger issues, I think it's just I have the megan downpipe which possibly has fitment issues with the ACD on a stock engine.

 

Yep get rid of that garbage and get a quality one should fit better with the acd. I know when I first got my car mine rattled but after looking closer hanger came off.

 

running balance shafts is a bad idea?
this is a daily driver. im going 2.4 to broaden the torque curve. i have a ss htz green, dont plan to upgrade so i likely wont exceed 500hp.

 

Its not that the balance shafts are a bad idea. They just add another potential point of possible failure in the timing system. And there are no adverse effects to removing them. You could argue there is more vibration. But I'll take a little vibration over ever having that silly little secondary timing belt break again.

 

Vibrations can drive bolts out of place....

 

Thank you took the words out of my mouth. That little belt breaks that throws the timing belt off and that wacks the engine and instead of spending 10 to 20 dollars for a stubby you just wasted 2 plus thousand fixing a broken timing belt because you didn't want a little vibration and spend a few bucks eliminating one of the biggest problems in any 4g motor.

Loctite if your that worried.

I drive my evo almost everyday with whats in my signature. If you have ever owned a 4g motor in the past, trust in what people tell you to do. I had 4g cars since the late 90s early 2000s and trust me when I say go stubby shaft. Sure a little vibration but you wont even notice it if your running stock motor mounts. Please see posts above.

 

i had the balance shaft belt let go and take out my timing belt about a month after i got my evo, so i can relate.
it shouldnt cost 2 grand to fix a broken timing belt. i spent maybe 300$
i have spent a long time pondering how to approach the balance shafts. i kept them in my 2.0 and figured i could leave them in my 2.4.
i have poly mounts going in the car.
its a tough choice for sure.

 

Ok with that said then you already know how bad it sucks lol. Did you inspect your head? Usually when a timing belt goes it takes out quite a bit in the head being the 4g is an interference engine. If you haven't I would pull the valves and make sure they are straight, and your guides aren't cracked.

And yes with poly mounts you will definitely see more vibration. It isn't overbearing but you do notice it for a little bit. I noticed my car rattled and was very noisy at first but once the mounts settled in its not that bad. Being I have Kelford 288s it lumps pretty good so you tend to notice it a little more but its not bad.

On the thought about the balance shafts like I said earlier its one less pain in the *** to deal with when they aren't in there. The benefits of knowing that its one less thing to go wrong.
