M20B29 w/ Triple Webers into my '71 2002

This should be a cool package. I plan on doing titanium exhaust when I do a 3.5" system.

I looked at specing everything out from them.

Nice, best of luck. I'm curious to hear it on your setup. I chose Vibrant for parts because a couple of their people are bimmer guys who have been friendly for a while.


LateFan - you're set then. I do all bending either by hand or with this tool. It's my favorite bender to date (yes, the 5/16 size gives the bends a little breathing room).

[LateFan]

No, just the undergrad right now (Aero Eng. w/ Astro emphasis). Very fortunate to be in a great group at Northrop where I've been able to work as an engineer without the degree. Similar to how Jeff was at Ireland ... whatever I can handle, go for it. Little intimidating, but not boring!

As for the wire, it's just basic stuff I had on hand. Stiff enough to hold the shape, but not too stiff where it's tough to bend. The wire gets you 90% of the way, but the last bits of adjustment are done on the car. Once you start working with it, you'll be amazed by how easy it is.

Nice!

The only ones I've done were new cunifer rear lines on the E30 trailing arms. It's pretty fun to work with. Did you use big sockets for tight curves, or a bending tool? I just kind of shaped them with various sockets and shaped by hand using the old one as a pattern.

Thanks, I have my fingers crossed for him! You're in grad school?

Wow, this is such nice work you're doing. What kind of wire did you use for brake tubing patterns? Like heavy electrical wire? I'm about to tackle an entire new braking system on my '67 Alfa, but with the engine in. MC to calipers. I'm a bit nervous.


Oh, EDIT - Is it in post 475, second pic, that fine wire?

[AceAndrew777]

Reichart12 - Thank you sir. An old local fabricator taught me that. I've now had to find excuses to break out the wire.

2mAn - As usual, my car remains a lawn ornament while you're actually enjoying the drive in yours! Can't wait to join you.

LateFan - Dude, huge congratulations to your son. That is no joke. I bet you're hugely proud of him, and rightfully so. If he ends up at Fermilab, please let me know! I've got some experiments needs doing, lol.


Finals are looming next week (yes, still in school), but I did get a couple little things knocked out this weekend.


1) Exhaust

In an effort to mitigate weight gain I opted to do a titanium exhaust system. Ordered a bunch of bits from Vibrant to make it happen. By my estimates, it'll end up being close to half the weight of the factory system. Overall, taking into account the M20 swap and all part changes on my "weights spread sheet", I'm getting very close to a net-zero weight difference over a stock roundie running a 5-speed. (a couple mufflers are not pictures).

A couple observations with regard to titanium ....

1) One goal is to have a higher pitch in the exhaust note. Titanium helps with this by simply being thinner. We are going to try a couple things with regard to header design as well, so it should be interesting.

2) When buying material, mandrel bends of titanium are actually much more expensive than the fancy "pie-cuts" you see on fancy aftermarket systems.

2) Brakes

Final brake system clearance checks..... and jeez it's tight. I really wanted to run the Alfa-brembo single-line brake calipers with e21 vented rotors behind the Diana wheels .... did a rough mock up a year ago. Did final mock up over the weekend. Looks like the OD of the rotor and the hat itself need to be turned down slightly. Rear 250mm drums also JUST cleared.

Cool OEM little bracket from the Alfa the calipers came off of that allow for a short section of hardline at the caliper. Made some new hardlines and had technafit make some custom flex lines to thread right in. This setup mitigates stress at the fitting, so we'll call it a win!

I'm alive! Just very busy (...now can publicly state I was working on the James Webb Telescope, [happy to report that my parts didn't fail, lol.])

Nice! I've been following all the unfolding and calibration steps. My son just graduated with a degree in astrophysics and is trying to figure out which way to go next. Fermilab, space telescopes on a mountain somewhere...?

I really like your brake line routing. Very tidy. You're doing beautiful work.

[2mAn]

As usual... speechless

[Reichart12]

Brake lines look cool. Makes total sense but never would have thought to mock it up with wire first.

[AceAndrew777]

Progress has been happening!


Firewall heatshield finished. Started with a butcher-paper template, then cut out of the DEI heat shielding material. Sealed the exposed ends with aluminum tape. Then started on the front brake lines (templates made from wire before cutting, flaring, bending the cunifer tubing).

Next up was the front/rear glass. On the 2002, this installation is done via the old/fun string method. It took a couple times (and a willing wife and child), but it's all in now. The hardest part is definitely the little locking trim strip.

Used OEM seals from Walloth and Nesch.

This stuff (sprayed in the crack) was a life saver.

Those hood props are awesome. I wonder if they make them for the 30.....

[econti]

...now can publicly state I was working on the James Webb Telescope

Now the quality of work makes sense

[AceAndrew777]

Whoops....

Also installed these awesome Koogleworks Hood Props (more speed holes!). With these, I was able to delete the hood cross bar and get some extra clearance.

A couple new OEM hardware pieces to round things out.

Thank you Simon and Moat.

3.1.22 Some more updates.

Headliner is now in. I do NOT like the OEM 2002 headliner, as it looks like cheap wallpaper from an old motel. Opted for the headliner material used on the E9 Coupes which has embossed pyramid details.

Doing the sunvisors in the same material, however, they are not quite done yet.

.Fuel and Brake Hardlines

At the beginning I mapped out the route for the brake and fuel line with welded mounting bolts. Now that the bodywork is done it was time to put the lines in. Running E30/E12/E28 mounting tabs for a little OEM+ action. Lines are made from 3/16" and 5/16" Cunifer pipe.

First, the gas tank was dropped in (little gold heat reflection tape added for good measure).

IMG-0142 by Adams Autosport, on Flickr

Prepping the mounting tabs (needed to drill them out for the 6mm stud size).

IMG-0527 by Adams Autosport, on Flickr

Started with the brake line.

IMG-0706 by Adams Autosport, on Flickr

Moved on the the fuel line.

IMG-0763 by Adams Autosport, on Flickr

Love these mounting tabs. There's a little piece of mind using the nylon versus straight billet.

Here you can see where they terminate up front. The fuel line ends with a flare and runs a 1ft. section of hose to the fuel pressure regulator. The brake line ends underneath the frame rail with a 2 PSI residual pressure valve. Will route it up to the brake master (just found a compatible Alfa master cylinder with a 23mm bore, so swapping out the 20mm E21 master for that!). Happy to have bought the 2002tii booster years ago, they are stupid expensive now.

Looking forwards to more updates!
