just got a dsm t25 turbo for my 99 civic si. looking for a manifold and downpipe, and im having a hard time. can anyone help me out?

drjondurst

yea how much do downpipes usually cost to get made at a muffler shop or somethin?

warren_teg

about 70 bucks. you can probably get a complete exhaust for like 150

use the stock 02 housing and ahve an exhaust shop make you a dp. as for manifold don't have a b series so i can't help you

Nobody makes a manifold with a T25 flange for Hondas (b or d series). Get a turbo manifold, doesn't matter which one in this case, then build yourself an adapter plate by going to the local welder shop and buying a 3/4" x about 4" piece of steel. Get the bolt pattern right on both sides, and bore out the appropriate sized hole in the middle. If you don't have any tools, the same shop you purchase the steel from will likely be able to build the whole piece for about $100. Same concept as D series guys do with HF/STD manifolds...

I have a T25 adapter plate that adapts it to an HF manifold for sale. Let me know if you're interested

Thanks

you might want to rethink using the t25. the b16 has a really high rev limit where as the t25 runs out of steam pretty early. not a very good match up. just a suggestion.

what he says is true. My freinds gst tends to die out near the redline and it totally stock. But your increase will be so great that you probably wont even worry about that right now. I got my downpipe done at the shop for about 50 bucks. Just get an o2 housing that came with the t25 and use that. The muffler shop can weld you a flange to match and you wont have to change anything permanently.

ACTUALLLY, HKS DOES make a turbo manifold with a flange for the T-25, just found it myself on their homepage. It goes for like $335 though. That's expensive(for me) but I sure would like to have one...T-25 and 14b share the same flange right??
