its for my jdm sir2 engine.thanks

 

no one knows?

 

Minimal at best, you'll need to get tuned to really take advantage of them.

If you change your cams you need to get it tuned to take full advantage of it.

Think of it logically, what's the use of adding more air (larger lift duration) if you're not also adding more fuel?

I'll math it out for ya:

X air = Y fuel

You put a cam on:
X + 5 air still = Y fuel.

You get it tuned so X + 5 air = Y + 5 fuel.

- hope that helps some.

 

understand.got it now. thanks.

 

type r valves are not a strait bolt in for a b16 head.

Why not? It's the same head.

orly? please, elaborate.

 

yes head is the same but the valves are 1mm oversized

 

I'm pretty sure they are not. I heard of lots of people straight swapping for Type R valves because they're lighter. By the way, valves don't "bolt" in.

 

haha^^ I definitly could be wrong

 

they are the same size...

just the shaft is cut on the itr's to make them lighter, some will argue that this makes them weaker...
