B16 Piping Size

[hellboyz]

Helo Otai2..just want to know,for light Mod B16A (ECU Rechip,Fuel Regulator,HkS Air Filter,PnP),For Better performance wat da suitable piping size?.. 2.2".,2.3".,or 2.5" ....how bout center bullet?.better install 2gether or not.?.. TQ

IMO, 2.25".. as to why.. see how big type B18CR one is. I think even the EK9 is 2.25.

According to a friend, 2.3 is the pipe standard in the US, so that's why it's slightly bigger, and more common there.. truth or myth.. I oso dunno.

tq mr.shirointenshi..anybody got other opinion?..

deyyy machaa..how many times want to change piping daa?? ekekekke.. 1st with 4-2-1. After dat with border + no bullet. after dats border with bullet. after dats "buluh runcing".

Not with new 4-1 extractor...ekekekkekeke....
I never know u did PnP already..ekekek sure fast one..:D

i think follow the collector size from the extractor u r using, if 2.3 then piping all the way 2.3, same goes if collector 2.5..just my 2 cents..hehe

Agree with Hanafyeg.......

this is a very useful topic with tried and tested info........they actually tested a b18cR with diff diameter piping......and they found out 2.5" gives the most power on it........another reason being if ur collector is 2.5" and ur piping is 2.3......bottleneck already.......they strongly beliff in a car being able to go from small dia. front to big piping back.....but never go from big to small piping......

altho the site is about b18cR....i think they same theory can be applied to b16's too....

 

[shiroitenshi]

Hmm.. it does look like the site promotes 2.5 inch, rather than 2.25 for the B18, but I think the B16 using a 2.5" pipe is just a little on the 'too big' side.

Well, if you think it works... go for it..

 

[Enthusiast]

i think 2.25 shud be good for you....also get extractors with a smaller collector so it doesn't bottleneck lor....that's about it....simple :regular_smile:

 

[akuma]

[hellboyz]
