What's a good turbo for Revving a B16a to 10.5k?
I have a built daily driven B16a All Motor I've been using for awhile, now I want to drop the comp a bit and run a turbo. I'll have about a 10.5:1 comp and I'll be wanting to run 6-10psi and have enough air flow to keep making power until 10K. I have my stock B16a cams I'll be using. What a good turbo for this setup?

How do you figure you have enough airflow to rev to 11K if you're running stock B16 cams? You're going to need something a pinch bigger than that, and some COP to get accurate spark at 11k.

the stock b16 cams wont be able to support power to 11k rpm, thats just from experience.

Agree fully DBL.....
Why the hell would you want to rev that high? Just being a ricer I suppose.........
8k-8500 is blenty with a honda motor.
Revving to 11k won't necessarily get you more power......unless you have some HUGE *** turbo that makes power that high.
it would be - hm..............pointless. Period.
Now - if you want to rev that high anyway - you'd have to get la lightened bottom end. Like a lightened crank - which would in theory make it weaker........which isn't good for boost. Unless you have loads of money to spend - its like you have to sit down and decide whether or not you want all motor or forced induction - can't have the best of both worlds(unless you have money).............

Re: (TheKingPin)
A b16a is ment to rev people!
Besides, I've already built my B16 to rev, I'm making power to 10k with NA. Been that way for 6 months without a problem. I want to be able to do the same with a turbo. Why only use 3/4 of the full potential of that motor? Sure, if it's a B18 only rev it to 8500, but with my short ratio tranny and a small stroke, you've gotta rev it to get more power! By maintaining your TQ at a higher RPM you get more HP. Make the tranny a shorter ratio and volia! you can accerlate faster.
So forget if this a good / bad idea, help my with my question. I guess stock B16a cams will not due. Maybe some High lift, short duration?

I want a huge *** turbo, that is the point of this thead. What "HUGE ***" turbo whould be good for this desired setup

I'm not running stock cams now, but I have my stock one's I was thinking on using. However, it looks like I need High lift cams to do the job.

The GT40R seems a little too big. Is there a way to rework a mistu or t3/t4 turbo a/r ratio or something to provide higher flow? I don't have the a/r stuff figured out yet. I figure with my target compression(10.5) and low PSI(6-8) requirements a larger turbo will spool to low PSI as fast as typical street honda turbo setup? I need it to hold around 10 PSI till 10k on a B16.

I'm not expert or anything - but I thought high lift cams would actually hurt the performance of a boosted motor.
say for example if you purchased to skunk2 stage3 cams -and then boosted.........i thought the valve overlap would reduce power.

I ran an 84mm B16A to almost 11k with a T4/T67 and ITR cams help you rev past 9500 really well!!!! You would do really well with a T3/T67 though actually due to spool characteristics of the short stroke B16A. And yes the B16A NEEDS to be revved to the MOON!!!!

So...........what valvetrain are you going with?
Which company makes springs that are reliable to 11k? I'm interested now........
So, revving that high won't make you spin rods?

I ran Skunk2 springs and retainers on my old stock head and revved to 10k , this ported head from RLZ Engineering has REV springs and retainers. no probs!

Good ****. I was thinking about the skunk2 full valvetrain in my prelude.......hm. can't wait. i might go to 8500 max though. Would be nice to have more top speed though.

I'm running KSM valve springs and Ti retainers. They allow you to safely rev to 11K. I'm only running to 10K N/A. I'm also using a Greddy Timming belt, stronger than stock for my current High-lift/durations cams.
