Well, I Am Going To Add Triple Webers To My 3.0L M20…

Curved trumpets. Easy to do with 3D printing.

Unfortunately There isn't enough space to add even curved trumpets. I connected with Lee in Quebec about his really nice manual setup. This is always a proven and available option. My ideal is to run power brakes if possible though. I just want everything to feel correct. I drove a friends E90 powered booster recently and the touchy nature made it difficult to heal toe naturally, like it does so well OEM. I am looking for progressive pedal feel.

i would investigate whether if you use a smaller booster from E90, 10 degree DCOE curved spacer (max recommended) to kick tthe carb up whether you can sneak in a curved smaller OD trumpet

Thank you for the info Digger. I feel like today I made the decision to run Lee's setup. I really like Lee, he is also a fellow Canadian. I would be running 2 x tilton cylinders. How do you feel about this setup for street driving Digger? Do you miss boosted brakes? I drove my friends exact setup 5 years ago or so, but I cant really remember the details. My touring is a street car through and through. I just cant get a booster to fit well unless its the iBooster. Thank you in advance for your input!

look into early m10/m20 manifold intake runners. have seen them used for curved runners ending in trumpets above the valve cover on e21 323i 6cyl builds with webers. not sure which ones worked best, they angled forward away from the booster toward the front of the car.

i have the Lee system ready to go but opted to try the e90 booster first to see if that was enough space improvement for my needs so i haven't actually ran the non vacuum brakes.
