I have everything I need to start my turbo build except a manifold, I was just wondering what you guys suggest. It has to have a wastegate flange and I am trying to avoid the stock manifold adapters. I'd prefer something resonably priced but it's not really important, thanks folks! Your input is appreciated! It's a 325i btw I plan to start a turbo build thread soon, so feel free to ask questions.

look for a Revshift manifold to come up used?
there arent many options new for under 1000 (unless you go ebay status) -
Ya not super keen on the eBay stuff, unless I know for sure it's a quality product, and when it comes to eBay there's not much quality lol
But ya I will have to keep my eyes open for a used revshift,Comment

Look into CX Racing's manifold.Comment

REV shift manifolds are unicorn now unfortunately ):
The best off the shelf manifold right now is probably CX racings.
It's tubular.
t4/t3 friendly.
Has a wastegate flange.
Clears oil filter/AC.
304 stainless.
Cons:
Not equal length
Gasket is junk
304 steel is light and can crack/leak if manifold was put together poopy
All those cons, especially the 3rd one, reflect the price.
With that said, there are a few of us using it with great success.

The cx racing one is the same one on ebay.Comment

A little pricey but probably the way to goComment

That cxr or whatever it is is ultra crap.
This is probably what you're looking for.
A revshift adapter is going to be the best though.
tcd you need an on center turbine housing.

Is probably the least efficient "best" manifold.
Have you used it?That cxr or whatever it is is ultra crap.
This is probably what you're looking for.

The one you just posted is TOTAL crap.
Fits like shit. 3 guys who are using it on this forum all said they had to cut/dremel to make it fit and it has no WG provisional.
Made of the same quality as the "new" one that fits 100% on the account of myself, kamotors, orcgrinder, cronopulos, and more
The only thing it's got going for it is possible equal length and 3-1 collectors.
Think of what engine this came off of lol. Flows the worst for his goals.
GANGSTER but pricey 8)

I'm using this manifold now instead of the new cx racing manifold and this one requires you to cut the flange in half for it to fit but it has great turbo placement and spools nicely.That cxr or whatever it is is ultra crap.

ak- you act like I just made fun of your dad.
Separate the banks and it fits nice. You can't weld? then get what
suits you. ;)
What did the forums guys dremal to make fit?
The crx was made to keep stock oil cooler it looks like and/or have a wastegate flange.

Yeah, you're right I'm sorry.
When I was on the prowl for a manifold I just didn't want to make the mistake to buy something that needed slotting/modifying/welding/extras, so I researched endlessly with revshift being the scapegoat till they announced they stopped production, then settled with CXr after personally seeing the fit quality.
Haha so it felt personal since I didn't want someone else making a mistake/regret/spend.
And I worded that wrong I think. Holes had to be slotted/enlarged to match the head.
