Newman's 1986 BMW 326rb build thread.

yeah, but i do not plan on doing a 6-2-1, just a 6-1 collector

I was talking with boardjnky about this. any reason behind this? space, and simplicity?

both. if i was using a twin scroll housing, then there may be enough to merit it, but just the increase in flow characteristics doesn’t outweigh the complexity.

cool its good to see you are really thinking into it :tup:

i think about EVERYTHING. It’s why i never sleep… And why i’ve been so cranky lately…

How thick is that rust-proofing agent? I’m going to pick up a can if it if it’s heavy and not priced like POR-15.

designed to go on at 3 mils

POR-15 is way better then that cheap shit.

:tup:

I think POR is 2 coats at 2 mils IIRC.

POR-15 = 35 DOLLARS
RUST DESTROYER = 30 DOLLARS

OMG IT’S SOOOO CHEAP.

Plus it’s called “Rust DESTROYER.” I’d pay the five bucks just for that :stuck_out_tongue:

HOW DID YOU SPEND YOUR FRIDAY NIGHT?

Schedule 10 304 SS.

Weight = 30.74 LBS…

Too bad I’m not baller enough to afford 321 thin wall… At 80 dollars for 180*, that’s $1040 in tubing alone!!! Yikes.

The green parts are constraints from the car itself. Here are the listings of the length of the runners:

Runner 1: 20.790
Runner 2: 20.861
Runner 3: 20.794
Runner 4: 20.759
Runner 5: 20.801
Runner 6: 20.786

Standard deviation: .033 (1/32)

Wastegate will probably be added after the fact…

thats pretty cool how thats mapped out. t4 i presume?

GT35R, T3 Flange…

it was about 5 hours of work…

damn that looks sexy…

how many cubes again? is there no way to option for a t4 on the 35r? and what a/r?

Displacement is 2.6L (158.661 IN^3)

There is a t4 flange option, but i don’t have it. My A/R is .82

Don did a lot of work sizing this turbo for my application.

I should be able to efficiently get 500-600 wheel out of this particular turbo.

pretty interesting. how big are the primaries

1.682

It was worth it.
