Got a question for all u turbo nuts.

would a B18/16 combo be good for turbo application??? (stock internals)
bigger displacement but high comp head?
would it responde better to boost than a B16a or B18c using stock internals

plz share me your knowledge

same ur money and spend it on the turbo setup (ie internals) IMO.

agreed...

which b18 block are you refering to btw?

B prolly, otherwise why'd he dick around with a 16A head

dont frankenstein blocks = very high compression?
doesnt very high compression = very high chance of detonation?

sure if u tune it PERFECT itd be great...but who can tune it THAT well is the question

no i am talking about

B18c (SIR/VTIR) vs B18c/B16a frankenstein.

Compression is lower with that combination unless u change your pistons.

what wynode just said. B16/B18CR heads will lower your compression not increase.

so as weq said, it's probably a waste of time and you're better building up your internals

compression is lowered by about .2 or .3, but from what i understand that is with the american gsr head which may or may not be different (slightly) to our ITR/b16 head.

In which case, the drop in compression could theoretically be a little better for boost, which is my understanding :D

Do you have both the block and head? or are you searching for a new combo?

US GSR is our VTiR. You got it a little confused, we are swapping the GSR head to B16/B18CR.

Why would it be better?

(ok I guess we could start a whole new topic on this but just want to mention that lower compression + higher boost isn't always going to give you a good power and as opposed to a high compression boosted car).

ahhh ok... either way, he's refering to the poor man's type r setup, which results in a slight loss in compression compared to b18cR.... my bad :D

why would you bother swapping a GSR head to a Type R block. A) type R block is pretty much the same, just diff internals, B16A head is better suited for B16A engine obv...

You'd only even bother with putting a new head on if you wanted to do a VTEC conversion...

Otherwise, whats the point?

You can change compression and flow characteristics without changing the head. It doesnt make sense to me.

no one is puting a gsr head on a type R block. I consfused the issue by thinking the gsr had the pr3 head....

Keep the b18c head.

Better than b16a from what Ive heard.
