bisimoto headers

Mine was "custom" made after I filled out their fax sheet and faxed it back in with all my details of the engine build. I also spoke with them over the phone about the specs. "custom my ass"



B18C5 fully built NA 12.0:1 and when the bisi header stops flowing there is nothing going to help it after 7500RPM, flat as the great plains of kansas.

Haha hilarious man, your cracking me up :), I say do your own calculations and work out your own pulse tuning then there no excuse if your gonna go custom..

:nice:
Bisi is misrepresenting their own offering/service; that my real issue with them.

Meh, I think you have definitely made your point imo, but whether people choose to listen to your experience is another question itself - Which is the only thing your trying to get across I guess.... :nice:. I won't be getting one that's for certain.

It makes me laugh though, people try to defend these manifolds - however do they even have one? Have they had it on their car on a dyno?
 
I for 1 am willing to trust tama666' opinion on them..

it sucks cause they look SOOOO GOOOD !!

it is crazy to think they quote 17whp ... LMAO its like K&N quoting 8whp from a panel filter on a stock B16B.. ( they haven't btw )
 
lol i just meant after watching your build i can see you ain't just putting them down for no reason...
 
5 min of google search and you find a few links to people having different issues with this headers from cracking on the welds to no giving you the results that they claim you will..."wich is the case of
our good friend tama666" he knows firs hand what a P.O.S this headers are and all he is doing is letting people know not to buy something that is not gonna work...
 
oh wow!
I never heard about all those bad experience or false power upgrade with those headers
anyway my first question was about the clearance for the AC wich impossible with this
but thanks alot for the infos!
I hope it's not the same for the other parts they make like camshaft and spring valve
