B-series Honda DSM manifold
 

I have searched far and wide and have only found 1 option for a B-series DSM flanged turbo manifold. Does anyone have a clue where I could find a CAST manni? Who sells these buggers?? Please and thank you.

you might have to do what i did im running a dsm 16g on my b18b1 i used blox cast iron t3 t4 manifold and used a t3 to 16g adapter plate i found on ebay

i had to use an adapter plate also for my dsm t25 on a b series, because tthe manifold i have is a cast nissan t25 flanged manifold the adapter plate was from blox.

Why not buy a B series head flange and a DSM turbo flange and build, or have someone build, a manifold? Probably a bit more expensive, but it would probably look better and definitely flow better than a cast manifold.

my manifold and adapter plate was $125. i heard that cast is the way to go for a daily driver street setup, but i never had a tubular manifold, so i dont know. i personally would rather have it work good, than look good.

I'm building a tubular manifold that is costing about $100-120 for materials. 1/2" flanges and Sch 40 steel pipe.
Working good could go either way. The cast manifold will spool faster, but the tubular will make more power... Durability wise, if talking eBay manifolds, yeah cast is probably best...

inline pro one of the best cast/log manifolds that i have come across fitment is beautiful run about $500 w/life time warranty

BMC makes some cheaper log manifolds I believe. I know cast is durable, but they notoriously have poor flow.

or not. If I had some measurements I could make a log manifold for like $100 in materials. It could be done with the two flanges, two 90* bends and like a foot of pipe or so.
