Interest in a S54 itb on M5x head setup?

[Talperian]

Talperian, where did this project end up? From your prior post, it looks like you were able to mount the ITBs with the plenum? Is that correct?

If so, what booster are you running in that pic? Were any modifications to the plenum required?

The project ended up being a success, in multiple ways. From a power perspective, we typically see 20-25whp over the m50 manifold from 5500-8500rpm on stock s52 engines. I've made about 200 adapters to date along with both cable and dbw throttle control kits.

I did not end up installing the itbs in a e30, but there are 5-10 people that have. Zacherle Ketring is the one that I would reach out to, he documented the changes required fairly well. I have a bunch more information and pictures on my instagram acoimunt @rabidracingdev.com

He was able to notch the stock s54 intake manifold and use that. He also upgraded to the e30 specific Karbonius CSL box and didn't have to make any modification from memory.

As far as the booster modifications go, I can't remember what booster he ended up using or how far he he had to offset it, but I'll message him and confirm.
