Didn't stay late today but shortblock is together, just need to slap the pickup and pan on. Going in tomorrow to get the longblock assembled and mated to the trans. Might be able to start vehicle install if there's an open lift.

Damn, Just picked my EVO last October and am in Chicago. Been trying to get out to events, but so far just car shows in the western burbs.

I think I've only been to one or two shows with the evo, I don't find them as fun as I used to but every now and then I'll get dragged out to one.
:lol: That, and I get bored. Every car out there: Looks like a race car but can't race car? Check. Horrible offset and sized wheels? Check. Tire stickers? Check. Rinse. Repeat. :crap: |

Sad, but true. I'm now 43 years old and I, literally, don't even speak the same language as those kids.

Well yesterday I got the engine from a block with a rotating assembly to a fully dressed engine ready to drop in. The only mishap er surprise I fortunately caught while I was timing the engine. During the whole time I had the engine apart I was on the fence about doing a balance shaft delete but in the end I didn't have the expendable funds to buy a kit that gets rid of the counterweights and I didn't want to run a stub shaft so I left them in. While I was timing the engine I found a slight issue with the rear shaft belt...
https://cimg8.ibsrv.net/gimg/www.evo...f6874f8f56.jpg So no rear shaft for me. Next time I have the engine out I'll either throw in a weightless race shaft or pull the stock shaft and turn it down in a lathe. Going to get the clutch and trans on the engine monday morning and crossing my fingers there will be an open lift to start vehicle install monday evening. https://cimg0.ibsrv.net/gimg/www.evo...71b14bee7c.jpg |
Without the belt, the rear shaft won't move. No need to machine it down. Or are you talking about the front?
I left my rear shaft in with no belt so oil pressures stay the same. My oil pump already had the stub shaft installed. I was gonna use both shafts, but I couldn't get that stub out. :lol: |

You can, but then oil pressure runs kinda high. I didn't want to have that problem either. I also wanted a turned-down shaft for the front, but I didn't have the extra $200, either LOL

That's a lotta trouble to go through, though. You think it would make that much difference, as opposed to just leaving it in there?

My goal is to get the car under 2700lbs retaining factory body panels and fuel tank. |
You can't run one balance shaft, it will cause issue. Just pick up the OEM stub shaft, they're like $30, and leave the rear shaft in with no belt on it (so you don't have to redo the bearings to cover the oil ports)

Car should be back together and running tomorrow. Just need to reconnect the hotpipe, downpipe, oil cooler lines, serpentine belt and front engine mount as well as fill it with fluids. Then I'll break in the clutch and engine and try to get it on the dyno before the week is over.
Gave the new clutch (comp stage 4) a try and was surprised at how light it is. I've grown used to driving on/off feeling twin and triple disk stuff but this barely feels more aggressive than the exedy stage 1 I just took out. But that's just initial impressions without the engine running.

I actually have experience developing balance shaft assemblies for OEMs. After reviewing hundreds of run hours of data on engines I can't say they really do all that much. Now I haven't looked at the design used on the 4g63 but if it's like most balance shaft systems then it shouldn't be of much concern to just run one. With paired shaft systems (pretty much all balance shaft designs) the counterweights on the shafts aren't canceling out each other other, they're dampening crank vibrations due to inherent design imbalances that all 4 cylinders have (by the way there are plenty of 4 cylinder engines that don't use balance shafts). By running 1 shaft you're just cutting that dampening weight in half, it's still in time with the engine. Either way, I'll find out.
