Intake manifolds: b18a vs b16a.... updates on build motor
 

I have an oppertunity to get one of each off a local guy for $30, both stock manifolds not modified..... i was wondering what modifications need to eb made to run the b16 manifold on the b18a? or if there would be any advantage at all, or if i can make soem crazy high flow contraption out of both of them

Re: Intake manifolds: b18a vs b16a
 

B18 manifold sucks period. and you cant use a B16 Intake manifold on a B18 or the other way around.

ynot redrill the flange?

Re: Intake manifolds: b18a vs b16a
 

yes i think im gonna re drill teh flange and run teh b16 intake on the b18 head

I'm gonna cut open the plenum of the b16 intake first and polish that bitch and what not, I think im gonna get an adapter made up as well to run a bigger TB

whats teh best TB to run on the b16 manifold?

Re: Intake manifolds: b18a vs b16a
 

the biggest you can get to fit?

This is where Im not given away free knowledge :)

Re: Intake manifolds: b18a vs b16a
 

comon you know you wanna help out!! I'm gonna buy both manifolds and then sell the b18 manifold to my buddy who needs one and then i'll just run a modified b16a manifold on my motor..... im thinking i'll run a mustang 70mm TB and deffinitly port and bore the ---- outta that manifold

Re: Intake manifolds: b18a vs b16a
 

doesnt anyone have anybody knowledge on this? or maybe someone can reassure me that a b16 intake manifold will flow better? if so where will the gains be made? i plan having a semi built b18a

im going to:
have head planed
dual valve springs
b18b camshafts, or aftermarket if good price
port and polish job
valve regrinded
block decked
crankshaft polished
cylinders honed
all new gaskets, bearings and seals
ARP head bolts
b16a1 intake manifold ported and modified as much as humanally possible
hondata style intake manifold gasket
70mm TB


whats peoples opinion on the build, I'm shooting for 150ho at the wheels before i even slap the turbo on, 230-250hp with the holset hy35 turbo

opinions, ideas? this is my first motor im doing up, any input is valued

Re: Intake manifolds: b18a vs b16a
 

once again try it and experiment.


Only took me years to figure out what works etc and make a livin at it now


good luck


Oh and just becuase you make something bigger doesnt mean anything in terms of flow :)

Re: Intake manifolds: b18a vs b16a
 

hey man respect the fact that you have done research and trial and error to see what works best, I myself am interested in just trying stuff and seing what works best and what not, Thats my whole theoretical reason behind modifying my car, to keep ideas flowing, to keep myself thinking and to keep myself interested in the field

some people may say that working on a car is a waste of time, or they will say modifying stock parts and designing new ones is a waste.... but if its enough to keep your mind flowing through teh years on an engineering degree, its not money or time wasted


I was just wondering if anyone had any insight of if it is actually possible to run a b16 manifold on my b18a if anyone has done it, or researched it before, i dont want you're trade secrets by any means :P I'll spend time researching and finding my own ;)
