E30 M52b28 turbo build

[Deanswaim1]

Okay guess its getting to the point on my build where mainfold is getting needed. Any recommendations of a good not over priced mainfold. Or anyone have one forsale?;)

From research, they're tricky to make/do correctly due to the wider DOHC m50. If I were in your boat, I'd save up the $500 to get a properly made one by rapid spool which has been suggested by many members. Worry free, quality product.

I'm about 50% done my turbo m20 build/install and what I've learnt is getting quality products off the bat, saves a lot of headache and most of the time money in the end. Go with the one listed below!

I'm sorry I can't provide first hand experience with it, doesn't seem like many people are wanting to or able to provide much assistance in this topic as my question below yours has gone days without any help.

Yeah they have good stuff, I've been in contact with them but I was just looking around. Yeah I had a built m20 I sold a while back because I decided to change platforms ll. Excited to get her done tho. Hoping someone is selling a used on haha.

Ahh nice, good luck, hopefully you can find one!

Thanks for plug, manifold pricing has been updated on our website.
We've added the E36 top mount to our line up and will be adding some more turbo accessories.

How would boost creep from a manifold? Maybe if your wastegate isn't working properly I could see that...

I can also confirm that it creeps significantly, wg tube is positioned horribly. needs to be modified

WG placement on the manifold is mostly to blame. Given the lack of space, it's the only real way to add a wastegate to the manifold.

That said, you could block off the manifold's WG port and install the wastegate on the turbine housing and that would solve everything, but not everyone wants to cut/weld their shiny new turbine housing, and then possibly do it again if they change turbos.

at 12psi on an S257, I haven't had creep yet. If that changes, I'll probably do this mod.
