Here's the deal...right now the set up includes:
JDM B16A
ITR cams
ITR throttle body
AEBS intake manifold
Megan Racing header (non-JDM)
regular eBay short ram
CTR crank pulley
Crome Pro tuned=163whp at 8100

The power was still climbing hardddd. I didn't rev any higher though because I have a stock B16 valvetrain. I would now like to change some things around and make 180whp w/ out touching the block. Im searching around and trying to figure out the best cams to get. Im going to throw a thinner HG on and probably use flat faced valves to raise the compression a tad to help the larger profile cams. I also just received my BPi velocity stack which should help a small amount as well. What cams do you guys think would net the most power for around a 10.8 compression B16, and is there anything that Im leaving out that might help me out with my goal? Thanks in advance

 

buddy club III+

that header isnt helping any either

 

Headwork and a well designed header

x2

Especially the header. . .

 

180 whp on a stock block B16 is going to be difficult. I would do BC3+'s with RM/Super Tech valvetrain and a Toda header.

yep and you do not need headwork, b16a heads flow plenty to support the power levels you want. Porting the head would just cost you money and probably power.

 

the bc3+ really isn't a high hp cam set, but it sure will give you a fat *** powerband.

 

Toda A's work very well in B16's also

When have you seen a GOOD port job cost power? I have seen otherwise stock ITR amd GSR motors pick up nice gains through the whole range with just headwork.

"good" port jobs are not that easy to find which is why most will cost you power. If you can find a good port job it will cost you good money and the gains per dollar wouldn't be worth it for an individual like the original poster wanting to make 180hp with a pr3 head.

 

10 psi, 2-3 hours of tuning.

 

So the BC spec 3's would be that much better than the ITR cams? I'll definitely be looking into a custom header from Hytech or something of that sort. Just can't decide on cams. I've always wanted BC3's but didn't really know how they compared to ITR cams.

They would give you better mid-range for sure. If you just want peak power, they probably aren't the way to go.

 

I want something that will give me a little more peak, yes but midrange would probably be the funnest for driving around town every day.

 

my advice, set a goal on how far in the operating range you want the engine to make power or where you want the engine to have the meat of its power. Setting power goals are usually setting up the end user for heartbreak.
