to do or not to do?

well i bought my motor this past weekend and the guy i purchased it from said to take out the balance shafts out.. i have done a little research and they say it makes more vibration... i have talked to a few peoples that have done it and they say it vibrates like hell and not to do it is it really that benificial? its a 7 bolt and i am running an evo III

Use a kit and get them out of there. The one going to the oil pump siezed on my first dsm which stopped the pump and blew up my motor. The extra tiny bit of vibration is a non issue IMHO.

There are so many 4g6x engines running around without them it's a no brainer.

The Evo X doesn't use balance shafts. Take them out properly and you'll be better off in the long run.

If you think the vibration might bother you then maybe not, but as far as reliability its more reliable having them out, most timing belt failures are caused from the stupid front balence shaft belt.

Pulled mine out of my original 7 bolt and never noticed a real difference. Take them out and move on.

The added vibration is minimal. Poly or solid motor mounts will add a lot more vibration than doing a balance shaft removal. You do get crazy vibration if you only remove the belt, or if you don't know that having the oil pump marked lined up when doing the timing belt only gives you a 50/50 chance of being right and you get the balance shaft 180 degrees out of phase.

alright im prolly gonna have a shop do it how much does it cost? and what hp improvements can i expect? and should i put 264 cams in?

**Shane@DBPerformance** · 03-04-2010

It's a pain to do with the motor in the car. Most people do it when they have the motor out for a rebuild. Who knows on power, maybe 5 hp. It mostly makes life easier and makes it less likely that the balance shaft belt takes out your timing belt. I would only put in 264s if you have a tiny turbo like a T25 or 14B, otherwise get something bigger.

96GST16g · 03-04-2010

so if i am running an evo III should get 272s?

**1ViciousGSX** · 03-04-2010

If you're going to make the change, go 272. 264 cams are not much bigger than stock.

96GST16g · 03-04-2010

then would i have to do valvtrain work?

**asshanson** · 03-04-2010

No, you'll be fine with 272s on stock valvesprings. Pretty mild lift on most of them for DSMs.

96GST16g · 03-04-2010

so what would be a good brand to go with that is relitivly cheap?

**goodhart** · 03-04-2010

HKS. I know Brad (C3L1CA on here) has had pretty good luck with his DKS (I think) cams.

**1ViciousGSX** · 03-04-2010

**asshanson** · 03-04-2010

hks 272 or FP2

Constant_Project21 · 03-06-2010

I'll be going with some delta k272's in my car this year, but those are a bit more aggressive. I'd say if your going for budget, BC 272's are okay....by no means the best. Better off spending the money and buying hks 272's.

cams are so expencive do they increase alot of hp? or is it more for torque

It's for everything, helps turbos spool better and give more power down low as well as help the engine breathe in the higher RPM range and hold power better to redline.
