Davegerous E21

[99sil-teg]

Awesome build, I've been playing with the idea of getting an e21 and I love seeing stuff like this

[Dave-ger]

thanks man.


Now if only I could figure out my diff situation. I'm 99.9% sure it's junk, the one I just put in is also not much good. I hear that E30 carriers fit in E21 diff cases, so I'm thinking of getting all new bearings, seals, R&P, and an E30 LSD. Any of you perhaps heard of this? seems like a good option, E21 diffs are hard to find, and probably equally expensive I would think. (haven't priced out these parts yet)

[Mr. Gumby]

It's actually the E36 small LSD carriers that fit with slight case modifications. I've rebuilt a few diffs for guys over in the E21 area of Bfc. Here's the write up I did on the first one.

Here are the part numbers and prices

I'll be swapping a LSD carrier out of a 3,91 into a 3,64 ring & pinion for a guy soon, he's gathering up parts. Feel free to contact me if you have any questions on the process.

There's an 83 being parted out in Cali and I think the diff is available, not sure of the ratio or if it's open or LSD.

Interesting about the E36 carriers. If that diff in Cali is in good condition and an LSD, I'm definitely interested. if it's open, I don't want it. I currently have 1 welded diff, and 2 open diffs. All of them are shot. LOL. not sure if the ring and pinion gears are any good or not. the pricing on those diff parts are discouraging, but I'll have to do something. when I get more time I'll look over all that stuff more thoroughly and let you know if I have any questions. Thanks!

Could you please re-up those pictures?
The text is interessting, but pictures say more than a thousand words

[Dave-ger]

ha, sorry about that. the bandwidth on those should reset in a while, if I get real ambitious I'll resolve the problem in the mean time however. Sorry for the inconvenience

[markshulikov]

cleannn

[Dave-ger]

thanks markshulikov.


by the way everyone, the pics are back up! sorry for that mishap there. Lately things have been slow for the car, but getting a differential legitimized is in progress.

Also, if any of you want to see some of the other stuff I'm up to with this kind of stuff, you can peep my page: http://www.facebook.com/pages/Daves-...594190?sk=wall


I just got a new job and I have a little family stuff going on, so things might have to settle a little until I get any more serious work done on my projects. I'll make it all happen though, I always do.

[Dave-ger]

lol, just busy right now man. I've been spending what little time I have on The White Whale (my new tow rig for those of you who don't know) and I was just letting those who wanted to see the pics know that they were back up.

Nice,Oregon FTW!

[Dave-ger]

Thank you.


some updatage:

Got my new holley 465 mocked up on the slightly modified intake manifold. There is a gap below the adapter setup, but that's because the stock carb spacer is going there.




My ghetto machined carb adapter. I had something way more complicated in mind, but thanks to Terry of Old Skool Vulcan Werks, I was inspired to do this:


It's not quite what he suggested, but his suggestion is why I didn't over complicate it like an idiot.


Lastly, I put the stock steering wheel from that "Igor" E28 which belongs to my home slice Alex. the horn and turn signal shut off deal didn't work, despite the fact that the splines did. I wasn't too concerned about the turn signal shutting itself off, but I really wanted to keep my horn. My solution was to extend the contact piece with an old CIS banjo bolt. I had to grind it down a bit more than in this pic, but this ugly piece of engineering sure got the job done.



and the steering wheel. I even got in the back seat to try and get a proper photo.

[Dave-ger]

I'm injured and making slow progress.

here's a shot of my choke mechanism that's confusing me. the "dvd footage" online for holley carbs says they only come with electric or manual chokes... this appears to me neither. This almost looks like a hookup for a hot choke to me, or maybe a fancy thread on vacuum thing? I'll figure it out soon enough with the power of google if all else fails.



and here's some mock up!


the air cleaner is too close to the alternator adapter bracket, but because I have heaps of hood clearance that I didn't expect, I'm just going to add another carb spacer to fix that. Seems like a better idea than an air cleaner spacer to me, plus the carb is closer to my dumb water cooled oil cooler lines and other stuff than I'd like anyways. the stock carb spacer is upside down in this pic, which was an accident, but I think it will work out really well that way actually.

oh yea, I'm also going to get a taller air filter for my air cleaner. I'm pretty happy with the 9" air cleaner, it seems like it will fit real nice.


lastly, a shot of the intake manifold I will be using next to the one I was using. you can see that the one I will be using has a lot of useless crap taken off of it, and even ghetto enlarged ports. I have to grind out my stock carb spacer to match real soon.



Thanks for tuning in!

[airkooled]

Love this car! the vacuum pot on the left is the secondary and the black circle thing is where the choke should be but isn't. someone forgot to put it in there!

[Dave-ger]

Thank you sir.


I knew about the vacuum deal for the secondaries, and I just checked it out, and it appears I have a heat choke. that threaded fitting leads to a small opening inside the choke mechanism and there is a coil type deal that holds the choke in place. I imagine it wouldn't be difficult to just put an electric choke unit on it.

For the hot air choke, I believe I need to buy this: http://shop.advanceautoparts.com/web...content=value4

kind of hokey, but it almost seems even simpler than an electric choke. probably cheaper too.


Another thing that concerns me is that there isn't a vacuum port for the PCV hose on this carb, so I need to figure out what to do with that. This should reduce clutter and be a good thing, but they way the emissions were removed on my 12A was kind of particular. apparently the vacuum stuff on my engine can mess some things up if it's not hooked up quite right. I need to look into that.


Anyways, here's a diagram of the carb, apparently mine's a bit different. LOL.





I'm kind of dumb when it comes to carburetors, but I'm trying.


oh, and just realized that I also don't have the vacuum port for the "full manifold vacuum source"

PS, I also just checked here and this is what I told The FitGarage to get me. it does say "hot air choke" on it. Looks like TFG definitely got me the right thing, only I'm seeing 2 different model 4160 carbs online. some have electric chokes it looks like, those ones probably have the extra vacuum ports too. I didn't know this at the time.


sorry if this post is kind of odd to read, I was doing some research as I was writing it, and I wouldn't be surprised it it's not laid out in an eloquent manner.
