b16b questions

[gelo]

i was just wondering
wot are the big differences between the b16a and b16a in terms of engine components
i know that b16b has hand polished parts to minimise friction

but thats all i know

Different pistons.... PCTs giving 10.8:1
Different head.... not just cleaned up but different valve angles.


Not 100% sure but the block height is also different (anyone confirm)?? or the piston height of the PCTs.

I know there is pics on the net floating about showing PCTs in a B16A with the flat part of the piston, "technical term" there :oops: sitting above the deck height..... seperate from the actual crown if that makes sense. :oops:

The problem this poses is that people have been thinking that PCTs in a B16A give the same 10.8 CR when in actual fact it is more like 11.4-11.6.

[tinkerbell]

PLUS the Integra Type R JDM 4-1's are NOT stainless steel

nor are the 4-2-1 AUDM Integra Type R ones cast... only the JDM Integra Type R 4-2-1's

where did you get your info from???

[Civic Type R]

you are correct Tinkerbell.
sorry, i was cross templating with the civic vs type R and ITR's comparisons ..
my bad.
but yes i will update that error.
cheers !!!!!!

[tinkerbell]

ahhh, a typo ;)

no problemo!

[Civic Type R]

PLUS the Integra Type R JDM 4-1's are NOT stainless steel

nor are the 4-2-1 AUDM Integra Type R ones cast... only the JDM Integra Type R 4-2-1's

where did you get your info from???
no theyre not !?!

why did i write that ? must have been a bad nite for me

[tinkerbell]

it is OK dude, it is just a common mis-conception regarding these headers...

the JDM 4-1's are just mild steel,

the JDM 4-2-1's are cast two piece...

but both have a 2.5in collector...

the AUDM 4-2-1's are also mild steel,

with a smaller size collector...

[tinkerbell]

BTW - it is a GOOD resource, i am just VERY pedantic when it comes to Honda, LOL!

if you want, i could go over all your resources for veracity?

[eknine]

yeah tinkerbell, just go over it and make it as accurate as possible...least here in down under we have something decent to point to :)

and i reckon Adam has done a good job in building the site :)

[Civic Type R]

i will confirm with my mate Miraii - who owns a JDM ITR in Yokahama.
He is a JDM Honda encyclopaedia.
