2002tii Brake Booster into E9 (Tripple DCOE Weber Install)

[nobrakese28]

Hello,

Is anyone running the Tii booster in their E9? I understand the linkage/rod needs to be modified to connect onto the brake pedal.

What about the brake lines? The Tii brake booster is about 2" longer than the booster in my 2800CS, just curious if they can be rerouted/softly bent into fitting or if they need to be completely replaced.

Trying to gain as much clearance for trumpets and air filters.

Thanks,

Marco

the tii booster is the best booster to use with Weber DCOEs you can buy a rebuilt tii booster from our member @halboyles with everything correct to go on the coupe.

My concern is with the brake lines, it appears that the 2800CS booster is about 2" shorter than the 3.0CS. I believe the brake likes will need to be stretched out or replaced completely.

My car is a 3.0, and I gently bent my existing lines into place. I don't recall the problem with coming up 2" short - your lines must be different than mine.

La mienne est également équipée. toutefois quand je l'ai achetée les filtres a air étaient modifiés pour cause d'encombrement avec le servofrein car les pipes d'admissions étaient des longues d'origine inconnu. Une fois installé le kit Alpina tout est rentré dans l'ordre.

the 3.0cs booster is thicker than the 2800cs. all 3 are ATE T-51 boosters, they are all just different sizes

Yes, upward horns like those in the Alpina airbox are a good option. I've gone with reproduction Alfa Romeo GTA horns:

I find it confusing that there are different boosters all sharing the T-51 moniker from ATE. When I was looking for mine, I searched for a 2002 tii booster.

Who's intake manifold is that?

Gothca, I appreciate the feedback. Current plan is to split the ATE T51, rework the clevis into a female thread to accept a threaded rod like factory. I went ahead and purchased bulk 3/16 line and the metric flare M10x1.0 tube fittings,

Korman. But Ray doesn't sell them any more. https://e9coupe.com/forum/threads/korman-manifold-mod.48012/post-421436

You can also buy six inch extensions for those brake lines at any automotive store that carries European brake lines. Most all of them do. Here's a link to our Tii Booster that has been designed specifically for the M30s.

Here's the Tii booster bought from Hal and the Weber DCOE 40 trumpets and screens bought from Pierce Manifold. I also have the Korman intake manifold on a Korman built engine.

Thank you @Drew Gregg for the pics and mention.
If you have triple side draft Webers, you might also check out our linkage designed specifically for the E3/E9s . It is not only much easier to install and maintain than the generic erectic-set versions, but also looks OEM and beautiful! (IMHO, of course)
