Compound Turbos on a 2nd Edition B Engine (9 Viewers)

[bsweaty]

so I pulled apart the spare automatic timer I have and looks like I’ve taken all the washers out of it for my Motor. however, the dimensions that they need to be are 14 mm OD 8 mm ID and then varying thicknesses as per the manual of 0.1 mm 0.2 mm and 0.5 mm
Here’s some photos of just taking one apart. They’re not too hard. It’s all done by hand. Just need some pliers to remove the circlip and two pry bars to remove the bearing

Also included are the pages from the manual discussing the automatic timer

@Busted Crank you’re a hero! I’m gonna order some up tonight. Thank you so much. Your timing’s perfect, I’m just getting my turbo fit.

Are you still going compound? Or just a single turbo now?

Single CT26 Mamba designed for the 14bt is where I wound up. I ended up with a 11bt manifold as well and everything is bolting up. I would have never had space for compounds reasonably, in retrospect.

Is that one of the Chinese 14B-T turbo manifolds from eBay? What's the quality like?

By chance, I got my 15B-T (same as 14B-T) manifold machined flat today to remedy warping.

Are you keeping the Bii intake manifold? What will you do for piping frpm the turbo to the intake?

@Eurasiaoverland https://www.unicornpowersystem.com.au/ProductView.aspx?ID=1426. this i the exhaust manifold I ended up using. quality seems decent. mount flange is around 10mm thick, so is the turbo flange, pipe is around 1/8" thick. welds seem acceptable. I did quite a bit of fab to make it fit the turbo the way I needed in my engine bay on my mid engine van. I can't say how well it'll hold up until I see 1200 egts. I will also be wrapping the whole thing in exhaust tape as I am basically sitting on it when I drive. where did you get your 15bt exhaust manifold from? seem good?

I'll be keeping the stock intake manifold and piping air over accordingly via intercooler. all will be custom. i haven't decided on piping size yet, either 1.5" or 2" will be what I can use. I don't have much space to work with, so it'll be a delicate and slow install. hot side to intercooler will be more straightforward than intercooler to intake. intake to turbo is a challenge too, this van has two air intakes factory. a lower pulling filtered intake, and a high clean air intake. you can switch in the cab, I am planning on keeping both and merging that pipe over / in front of / behind the engine. BUT I haven't found the simplest path yet.
