anyone done this? some guys say the b16 head flows better single stage intake manifold etc...is this a worthwile mod? i have seen b16 heads go for 700ish you can sell a gsr head for almost the same price...and just dump some cams into the b16 head. i was thinking about doing a mild port and polish to my head but i cannot afford the downtime as this i my only car. Opinions? is it a direct bolton onto the gsr block?

 

I am rebuilding my gsr with a b16 head...

I am sending it to portflow for a p/p job to help with flow...

the head is a direct fit... it will lower your compression by about .2 or so, but makes up for it in flow...

 

i'm adding a itr head to my car and then turbocharging it. not really the same but they are close. and you can find them cheaper than 700. As a matter of fact my friend will probably be selling his sometime next week. He was going to put it on ebay but i'm sure i can talk him into giving you first dibs if you offer him enough. If your interested email me.

 

I second that opinion. Good **** to work with. ITR manifold drops in real nice w/o mods.

 

Thanks for the replies. Are there any issues with hooking up the sensors etc from the si head to my odbI car?

 

does a b16 headreally flow better than a gs-r head?
even though you have an aftermarket intake manifold
on the gs-r head?

 

Yes... the stock b16 flows better than the stock b18.... the combustion chamber is also slightly larger... With a p/p on both... the difference in flow might not be to noticeable... but that depends on the quality of the p/p....

 

I'm using a SIR mani on my b16 head.

 

the b16 head flows approximately 5% better than a b18c1 head.
