Got some goodies today. Reinstalled the rear diff, looks so pretty, and so does everything else. Saturday will be the day trying to get the transmission and transfercase back in. All I know is that it's going to suck.

Rear diff comes with a neat sight glass which was where the oil fill plug was and the fill plug sits a little higher now.

Looks like they did a very thorough job!

Odd fact...Evo and STI both have similar rear diffs...based on a Datsun R180! The parts look new which are always fun to install vice grease balls. You can do it!

cool to know. Ive got 2 r180 sitting at my Dad's house. One day Ill get around to reassembling the car it goes to... :(

Hell, with the value 240z's have these days it would probably end up making me money if I were to sell it.

I think remember a good year or two ago you mentioning you something done with your rear diff(maybe something with the clutches), what was that? I did also get a 12 plate clutch in the rear diff as well.

Got the transmission, rear diff and transfercase in, still have a lot of random stuff to put together before I can start breaking it all in. Did run into an issue where a subframe bolt (common issue on evos) basically rounds off and to access it you have to cut a hole into a piece of the subframe to get to it... yay.

I would be at the home stretch since all it needs is fluids but ran into an issue with a subframe bolt so I will need to get someone to do some cutting and welding to address it :bangwall: .

If you like a little more power oversteer Steve, then you might like the changes :grin: .

How big and how rounded off is the subframe bolt? Could you save some time and weld an arm onto it?

Picture paints a thousand words, well probably only like 30 in this case.

Anywho in this pic you can see the nut that goes onto the bolt. The head of the bolt is in the subframe but has come loose and is spinning. Last pic shows an example how the bolt is placed.

One option is sticking a screw driver to help it not spin but didn't work for me.

So people cut to reach the bolt to tack weld it so it doesn't move.

I have none of the stuff to do any of that so I gotta pay someone to help do that for me.

We had to do the same thing on the front of the Festiva. Damned hidden captive nuts!

Had a person stop by and cut and tack weld the nut. It worked!

Anywho everything is back together and running. Thought I did something wrong since there was a wobble clunking noise coming from next to the gearbox. I had the car off the ground with no wheels on so when I engaged the drivetrain, the sound would happen and make more clunking thumping noises when speeding up. Well it ended up being the rotors. I forgot the rotors aren't fully on until the wheels are tightened :smack: .

Anywho my aem air fuel ratio gauge is just showing 14.7 non stop so I think something with the sensor itself went bellyup. Also I gotta fix the front ends alignment since the tackweld job required the coilover to come off.

Break in is 1000-1500 miles before I can go all out. So see you guys in a little while... :(

We could drive it to the Keys and back if you'd like? Nice easy road miles. During the week even. Kind of like the guys who used to break in other's new shoes by walking around in them.

So far the car has 2 autocross events under it with the rebuilt drivetrain and everything seems good. Transmission shifts better, there is way less "play" from when the car is at a stop and you accelerate on and I use to get this clunk when backing out of a driveway in the rear. I thought it was brake pads just having a small amount of play but I guess getting the rear diff refreshed it got rid of that problem.

The rear diff has more locking now and the last event was a pretty good course to test it out and Im happy with it. I didn't have any issues going through the course with understeer when accelerating. I did get some pretty crazy power oversteer on the streets but my previous tires (rs-4's) were done, hard as a rock. So I'll assume the power oversteer was from the lack of grip.

Did get RE-71's put onto the car(first time running them) and right out the gate they seemed pretty damn good. I got them installed sunday morning and did my autocross runs that afternoon. The first lap I underdrove expecting them to be very greasy. They were slightly but again, underdrove. By the third run I put more and more faith into them and they gave this strong grip feeling into the steering wheel when at the limits. The rear also gets a very nice grippy feel when at the limits(the RS-4's never felt like that for me). The RS-4's felt like they were almost sliding around and that made me focus more on being smooth which isn't a bad thing. I definitely need to be a step above what I'm doing currently with the 71's, I feel like they have more grip but I didn't deliver in the drive side. I could've been more confident in them and trust them more. The Rs-4's getting rock hard made me a wuss when at the limits(a lot less forgiving), just need more seat time.

Would I get RS-4's again? Naw. I was expecting more life out of them since they had a lot of praise about tire wear being minimal. Yes it had some less wear than my only other 200tw tire falken 615k+ but by the time it got to the wear bars, they were done. I noticed the slower the tire wears after an event, the less grip it has. Basically by the time the falkens and rs4's got near the wear bar, they wore like iron and the grip dropped off the cliff. We'll see how the re71's do with double duty DD/autox. If I can get them near bald and they still hold the grip then I'll be happy.

I feel it must be stated that daily driving on worn RE-71s in the summer.. in Florida, is a turrible idea.
