Yes, it is.

sweet!!! thats a pretty good way to easily convert to an external wastegate. i bought a rwd sr20 manifold (mine is fwd)... and running in to clearance issues with the lower front tranny mount because of where it directs the turbo.... this might be my answer.

Alright JD, no real difference in spool time. My new setup spooled slightly faster, but that is most likely due to a couple of old cracked leaky couplers on the last setup. Haven't gotten to the dyno yet. My ass says it's faster, but you know how those things are. :P Next it'll go up after I make sure there are no problems. Dyno time is money, not time dicking around.


The sinktrap however does show a slight improvement in spool time compared to a HF, but I think the single tube sinktrap significantely chokes the exhaust flow at higher rpms.

wow those are some damn good manifolds and even the ones made from stock civic manifolds

Re: Top Mount Manifold AKA the SINKTRAP
 

sorry if i missed this in your post... but what size diameter pipe did you use for the 180 off the manifold? looks like 2" maybe 2.5" ? thanks.

edit: and what gauge pipe is thick enough? do you think a 180 bend in 14 gauge mild steel would work? thanks.

I'm considering doing a sinktrap for expediency's sake on one of my cars. :)

:yme too

dude thats sweet!!!!

Re: Top Mount Manifold AKA the SINKTRAP
 

That was done with 16g steel in 2". The stock 4-1 manifold merges down to 1 3/4". I ported it out to match. A 2" T3 transition from racing solutions was used to make it easier.
I would like to try another using 2.25" piping. 14g steel would be better.
A must: Use the factory manifold to block bracket/brace. Also, another brace for any Sinktrap should be added.
