Honda: BB, or JB BBK?

Im thinking the bb for faster spool and reliability. My friend has the hks and that thing spool amazingly fast. That's why was looking at getting one.

The HKS turbo definitely spools amazingly well. I have the original version, and it has been pretty strong. I don't have the wastegate issue like some people are mentioning. Having heard all the comments on warrantee, I'm a bit concerned of being able to find rebuild parts when the time comes.

Honda-guy,

I've dyno'd my car next to Jeremy's Evo 9 (same mods except he had the BBK JB when I had the HKS 7460... dyno's were literally overlayed on top of each other)

If you want the HKS 7460... buy the BBK Full Ball Bearing unit. You'll be waaaay happier!

Let me know if we can help guys-

we CAN do a BB full with A/S cover if you want-

Hey Chad, how much is an A/S cover for a JB BBK-Full by itself? Also is there a conversion cost reduction from a BBK-Full JB to a BBK-3B? I'll be at the very least throwing an A/S cover on the BBK when I build this 2.3L.

our cover is $158.50

there is a conversion discount but it isnt much, since we replace pretty much everything in the turbo-

That's not too bad though as long as you can use the turbo. I'll give you a call over the winter and see what the best choice for me is.

I have a HKS GT II 7460R...on a 2.0L at 32psi spike on mustang dyno the car made 412AWHP and 385AWTQ...on a 2.3L at 28psi same modes but on a dyno jet the card made 497AWHP and 498AWTQ...stopped at 28psi because of fuel pump issue...plan was to go to 32psi...so very shortly I will post a dyno graph once the car is retuned...I am hoping for mid 550 TQ and HP...I have no problems with this turbo...the TQ is insane and the spool on 2.3L is below 2600RPM...I have the original verison that came with the cams...the wastgate does not get loose like some have described here...Had my hotside ported and coated by MAP...not sure if that helps or not...at the end of the day ALL tubos had some sort of problems...for every failer there are tons of success stories out there...the only thing that sux is probably lack of support by HKS since after all we are not in Japan...a bunch of rally guys are running this turbo and make crazy power...not sure why couple of failures described here would turn people away from this turbo...but to each his own...

would like to see dyno and full mod list for 497/498 pull!

I will have a new dyno once the car is retuned...I lost the 412AWHP/385AWTQ mustang dyno on a 2.0L...and the 497AWHP/498AWTQ dyno jet on a 2.3L was done locally by the shop (APM Auto Performance Modifications) out of Chicago that put everything for me...they were suppose to e-mail me a copy but never did...doesn't really matter to me because they stopped at 28psi and didn't go to 32psi like I wanted until I reslove my fuel issue...I will definately post a dyno graph once the car is retuned...should be sometime this month...I hope...I was still very impressed with the power given the boost level...

As far as the mods go...the most important things I guess...
fresh 2.3L 9:0:1 motor
HKS cams...once that came with the HKS 7640R turbo
MAP ported stock exhaust Manifold
MAP ported stock intake Manifold Rev 2
the car is SD on E-85
AMS TBE and intercooler...
65mm TB
double pumper with I think 1200cc injectors...not sure on this had to switch them out during original build but they are by no means maxed out as I was at 69% duty cycle according to the shop...

that's about it...notice how switching to from the 2.0L to 2.3L the TQ jumped so much from 385AWTQ on mustang...thats about roughly 430AWTQ on dyno jet with 12% loss between the two dynos...to 498AWTQ on dyno jet...68TQ difference and about 38AWHP difference...

By my estimate additional 4psi should net me additional 60-80 HP...with that set up...we'll see...

I thought about running a spike to 34psi...but seems the turbo runs out of efficiancy at about 32-33psi...I think the people in this thread that had issues with the turbo ran it past its efficiancy level...at the end of the day the turbo blows hot air...perhaps that had something to do with the failures...I know R/T Ernie ran his turbo at 36+psi...maybe he can tell you guys more...

Is that on a 2.3L or 2.0L? so how do you like 4,000 RPM powarband ...this turbo kicks ***...how much boost were you running? on e85? what cams?
