It does since the fuel pump, filter, etc. are on the right side normally. Since he is running a fuel cell, it opens that area up for interpretation.

I do what I want!

But yes, I moved the fuel pump to the drivers side since the fuel lines run down that side of the car. So I moved the exhaust to the other side.

The eE21s that I've seen corner-weighed are also a tad light on the rear right corner.

There is a meaning to your madness. I like it!

cheap glasspacks do indeed work well. they definitely helped with the rasp on my car.

Im always hesitant with cheap glass-packs because they can fail. If they are welded in that means redoing exhaust, and Im not a fan of working on exhaust..

Just wanted to drop by and say hello.

I guess I'm finally old enough to have some proper dad shades. I think I've had those since maybe 2003...?

I bought some glass packs from http://www.heartthrobexhaust.com/glasspacksandflowpacks.htm The shell is much thicker than el cheapo ones, but they were very resonably priced, just call to order. I think I paid under 60$ shipped for a pair of small ones. I would never buy Cherry bomb or Thrush after using these. Made in Litchfield Minnesota too.

Got the car back together enough (barely) to take a couple beat-runs down the road in front of the shop. Can confirm that the exhaust is not just loud, but also obnoxious. Still no floor in the trunk, and no back seat, so the exhaust might as well be plumbed right into the cabin. It's the kind of loud that you can feel, as opposed to just hearing it. Also still missing one of the side windows. That combined with the not-car-culture-friendly temperatures this weekend, stiffer suspension, manual steering and general fear of things falling apart or exploding made for quiet a visceral first-drive experience. I survived, nothing broke, but there are more things left to do than I have fingers to count them.

I thought I did a pretty good job bleeding the brakes, but they didn't work worth crap (try rev-matching your downshifts when the brake pedal goes straight to the floor. It doesn't work well, but it's worth a laugh...). Bled the front, which made little, if any, difference. Will have to try re-bleeding the rears next weekend. May have a leak somewhere? Who knows...

Body roll is still substantial, even though my spring rates are 2-3 times stiffer than stock.

Also can confirm that Hankook RS-4s are no match for the mighty torque of a tired M42 when the temps outside are near freezing...

All-in-all it was a good time. Much work left to do, but definitely excited to get this thing out to an autocross or ten this summer.

The ride height and “stance” look great!! It takes a lot of lowering to make an e21 look like that. So to recap your suspension changes, you relocated the subframe mounting points, changed springs and dampers, and what else?

HipMF

The front is shortened strut tubes with Bilstein mk-I Golf inserts. This is a pretty well documented "mod" on the internets.

The rear is...... "custom". The subframe mounting points have been moved up about 2 inches so that the car can be lowered about the same amount without effing up the geometry. The rear on e21s is already a coil-over, but the stock dampers are too long, so for the time being I've replaced them with some cheap Bilstein coil-overs that are intended for circle-track midgets.

From what I've read, I think what I need is a "digressive" damper (ie a lot of low-speed damping, with less high-speed damping). This helps control body roll, but still allows the suspension to absorb bumps. I've converted the rear to 1/2" heim mounting top and bottom, so I can swap that out for any 'ol coilover damper that I feel like. The fronts I believe can be modified to be take-apart shocks. Bilstein shocks, internally, are all very similar. So, once you can take them apart, and have a way to recharge them with nitrogen after you put them back together, you can have them re-valved to whatever damping you want, provided you can find a competent shop to do the work. I feel like my spring rates are in the right ballpark, so I'm thinking it's the dampers that are failing to keep the roll in-check.

Do you have a rear sway bar?

Yes, it's a stock one I found at Gibsons.

Question of the day: Is my car over-heating, or is my temp guage being an a-hole?

The temp guage in the car occasionally bounces around for no reason, but seeing it way above middle is still disconcerting.

Top radiator hose is plenty hot. Have spent much time bleeding with no change in results...

HipMF

Nevermind. Finally got the courage to just let 'er bake. Head temp went from ~200 to ~210. Temp near thermostat shot up to ~190 and the entire radiator got hot, as opposed to just the area around the top hose.

So, apparently the T-stat opened. Guage still displayed ~3/4, so apparently that's my new normal.

My brake lights were also on constantly, and I had to adjust the switch to get them to turn off, so, apparently somewhere between 33 and 35 years old is when e21 electrical systems start to shit the bed...?

Jdesign

LOL.

Oh man that gauge would worry the shit out of me. Maybe the sensor for it is bad, or the SI batteries? Does it even have those?

sooo... updates...

Battery is in the box and tied down, but I still need to get the cover that I made for it installed.

Was having some tire rub in the rear, so I rolled the fenders a bit. Also man-handled the front fenders around enough that it mostly doesn't rub.

Spent 12 or 15 hours clay-barring the paint. Aside from a ridiculous amount of overspray that I didn't even realize was on the car, there was 2 1/2 years worth of shop dust that had done bad, bad things to the paint. I'm actually pretty surprised that it cleaned up as well as it did. My method was more like you'd use a pencil eraser than the "glide the clay across the surface" technique that's normally recommended. I think a light buff would make it look pretty nice, but that's pretty low on my priority list right now.

Made it to the picnic!

The car is stiff and loud. That combined with the constant fear of smashing an oil pan of something falling apart made for a pretty exhausting drive.

Speaking of things falling apart...

When I put the subframe back in I had to loosen the bolts that hold the subframe bushings to the subframe to get everything to line up. Apparently I forgot to tighten them... None of them fell out, but none of them were tight either...

Also the LSD that I put in blew the input seal. It lost a good pint-and-a-half of fluid on the ~240 mile round-trip. Most of it appears to be all over the bottom of the car. It's back on jackstands again. Equilibrium has been restored.

Your cross country road trip in that car still inspires me. Youve done cool things on that car. We were talking about how decent the exhaust sounded as you pulled into the picnic as well.

YoungCR

Forgot to ask for a proper demo of the exhaust but it did sound good coming in! Was glad to see you driving this car.
