you know, you can always fabricate your own intake manifold.... And you look like the kinda guy that would do it.
I'd cut the stock runners shorter, port them as hell, weld a bigger plenum and see what happens.
Even if it's not perfect, it can help telling you whether it is the restriction or not.

Look for a Skunk2/Blox manifold here on HT. I was able to pick one up recently for $150 shipped.
boricuatuning offered me one for $160 shipped, I'm sure he still has it.

Re: Top end Problemes tuning my B22b on Crower 404
So there is no probleme to my top end power.
Crower 62404- 62403 or 62402 are all smaller than crower clame and wont make power in the 8000rpm range against you raise 14:1CR in a B16a nonvtec head LOL
The hp never drop before 7500rpm the cams end. so that indicate to me that the set up was very well done and maximise the power.
There is nothing really bigger that the Crower 62405a as nonvtec cams.
even grind by others compagnies, are about it.
so only Custom grind can be done to really make power on a nonvtec. but no Big core for big lift available.
THIS is one big raison why you dont see many nonvtec built
Jeoff from Colt cams is verry nice guy.

But I'm a nonvtec lover (former 10.4:1 ls w/404s and t3/t04e...sweet)
I don't think that the stroke itself should be lowering where you CAN make power...but all else equal of course it will shift your powerband. Your setup right now (aside from the bottom end) seems like it'd be perfect for an aggressive 1.8l nonvtec or even a stock displacement b20.
I hope you get the results you want...but ~220whp definately seems to be a tall order for 404s, but with 175 wtq NA this is already a success!
I'll be checkin your threads for track updates...Get some vids too!

Ok, swaping intake and TB.. redyno the motor. if no gains...
Who gonna pay that IM and TB ??? its about 800$
I already pay swaping a to small headers..
WHERE DO I GO ON 1 3/4 HEADERS ??? some have said.
But 0 gains... LOST on 2 1/2 headers... That was so nice !!
that also show that we lost velocity at top end...
I said i dont want get more hp at 6700rpm. i want it to be at 7700rpm.. i dont want a little change. its a major probleme here.
i dont know how you think its working. but what ever the intake manif.
if the cams are still having some juce at 7700rpm. it would be noticable,
if i swap an Si-R im. i will still have some power at 7500rpm. but lower.
but still making power.
So you are saying that, if swaping Si-R IM, Then i will have to cut off 7000rpm against 7500??
If i can't at lest, bring back some power in the 7700rpm range. All the work to get a better top end is useless.
i first want the motor to show some ability to keep power after 7500rpm... or, I will HAVE to buy some bigger cams.
No shorter IM will bring more air at 6500-7000rpm ( my currently power band )... maybe at 8500rpm it will... But i dont go there. think about it also...
its not that i cant help some people also.
I do have a probleme with this one... or i have been fooled by the 404 spec.
What ever,
I dont want nobody to get frustrate or get mad cuz i cant make all the tests i heard.
in the futur we will see what is goint to happen, and everyone will learn from it.
Respect, to all of you

Re: Top end Problemes tuning my B22b on Crower 404
I know, 
this is why i did a non vtec first.
but there is no good cams on the market that i want.
Or iv got no time and money to weist testing them.
Custom cams could make power, but i wont go there.
i wont spend more on testing the nonvtec
i will built the vtec one. Less interesting but more powerfull

Re: Top end Problemes tuning my B22b on Crower 404
Have you tried adjusting cam timing?
I had 2 cams claiming similar specs, one was BC another was Bisimoto...the Bisimoto peaked higher and produced more torque everywhere...I believe in Bisi.

Great to believe in Bisi, but i send him several messages and i am still waiting.
I told him that i want custom cams for my built.
I finaly went to right it on his 700whp turbo project tread and it still been waisting my time.

Re: Top end Problemes tuning my B22b on Crower 404
I finally gonna go for custom grind cams. My Top end problem WILL be resolve, will see if my motor tune up is good for over 225whp. i would say, of course !!!
Now i peak my hp@6500rpm... 7500
I want it @7500rpm... 8300 Only the cams will be swaped.
See you in 5-6 weeks...

Bisimoto
By the way, they need my curent cams to analise and make the new.
I guess we will have the real Crower 404 cams spec.
Unless they are not allow to tell you...

Re: Top end Problemes tuning my B22b on Crower 404
I believe it in your manifold more than the camshaft, the SI-R manifold just doesnt have the plenum volume I believe you need.
If your looking to peak later you need a larger manifold.
Remember Bisi is a salesman first, but the best advise isn't free.

Does Bisi have a cam grinder? Or is he subletting it to someone else? It's unusual for a small shop to have a cam grinder.

Re: Top end Problemes tuning my B22b on Crower 404
That makes more sense then blaming a set of cams at this point.
