Looking for B series manifold for Evo 8/9 turbo
Preferably able to keep my power steering on a B16. I got the turbo free and looking for a manifold that someone isn't using or someone that can make it for reasonable prices . Thanks

A few companies offer manifolds... all are "ramhorn" style and all allow PS, AC is a no go
Race-Tech, UK company and the manifold isn't cheap
CTD Fab - impossible to get in contact
Toxic Fab - will build one by request
You're looking at least 600 dollars for a manifold, If you can get someone to make it... Race-Tech is 4 figures expensive
Your best bet is to find a local fab shop and see what they say
also which evo turbo do you have? The 9.8 housing is too small. You want the 10.5cm single flapper wastegate turbine housing

you might see a slight power drop off at higher rpms, this would be a result of the small turbine wheel (it chokes really bad at high psi at round 6500rpm) and the 9.8 housing, does it have the dual wg flapper? these had issues regulating boost pressure and mitsubishi/mhi swapped over to a large single flapper.
the 10.5cm turbine housing is preferred both by evo owners and anyone using an evo8/9 turbo on other motors... It will help with top end power with an un-noticeable affect on spool/response.
but at only 250hp you should be fine and not have any issues with any significant power loss in the higher rpms. now if you decide to turn up the boost, the 9.8cm housing will become a restriction very quick and you would be wise to find a 10.5cm housing.
Also, the 10.5cm housing does an amazing job of balancing manifold back pressure between the twin scroll volutes, something the 9.8 struggled with. However again, at 250hp on the 9.8 I would expect manifold back pressure to be minimal

Yea I mean I DD this car and it's just a fun reliable car. Since I'll be purchasing an Evo in the near future , I don't feel the need to go ***** out crazy on my civic. Just need to find a person to build me the manifold reasonably priced.
Again, wantboost showed you the companies that make them on a regular basis. Anything else has to be made custom by a good fabricator.. Nothing really to add. Time to get to work so you can git 'er done!!
You may be able to use a standard T3 manifold and use an adaptor plate to mate to the turbo. However, you will need to account for another .75 inch drop in where the turbo will sit. Im pretty sure an adaptor plate could be made easilly by a local machine shop or good old e-bay. Just a thought. However, it is likely the t3 manifold will not be set up for twin scroll, so you would loose that benefit.

From a T3

To an Evolution 8/9

His best bet would be to check out JM Fabrications to get the Evolution 8/9 flange and to make his own manifold (or have it custom made) if he doesn't want to go through the sources wantboost listed.
