Yea, funked bearings will decrease power output a little, depending, but if they free spin w/your fingers, then I wouldn't think thats the main issue...hard to say b/c I can't see it.

Unless he did some testing, or looked the turbo over, his "excuse" is b.s.

On your setup, you should be making no less than 300whp, w/500whp being your max for reliability on a GOOD tune, which I don't think you are getting imo.

3" exhaust is a MUST on all turbo apps imo.

I agree also. They say they are best in areas of Hondata and are a big tuning place so I figured they were right. But I don't know for sure. I start spooling near 4200 and hit full boost by 6400 maybe?

If that tells you anything.

So do you think it's a bad tune which is causing me this power loss? I mean we took it to one of the few places that seemed real. Mostly because they knew Hondata and others very well.

I can see a 2.5" pipe limiting my power output but I should still atleast be in 270s+ .
I've seen a few people with very similiar setups as me with 2.5" pipes running very near 300hp.
Dunno what's wrong.

What turbo again ?

If it's a "smaller" turbo then you have problems somewhere. It could be a turbo issue, or a big boost leak...but somethings up.

/edit - as stated earlier in this post, you aren't going to make good power on 2.5" piping. 3" or go home.

T3/T4 Turbonetics 57 trim .63 A/R

Not a small one but not a big one either. If I had boost leak then it wouldn't let me get up to my full boost at 11 psi right? It does get all the way up to 11.

And I understand that I need 3" but as I said earlier other people's setups are very close to mine with much more power. I'd rather solve this problem and get the right expected power out of it then go throw more money into upgrades that I put onto a tweaked setup.

Does it hold 11psi at full boost and doesnt drop?

damn...thats a low #s for sure. not crazy low but should be around 270s easy.

On 11psi I was over 300, 15lbs netted me like 330/350whp iirc.

Hits 11 psi as I said near 6200 and holds till I let off.

So I don't really know. If I find my dyno sheet I'll get a pic up for you guys.

EDIT: I found my dyno sheets but still waiting for the pics to get to my email. Should have the pics up shortly.

Catless & go 3' straight through should gain you 20-30whp.

Good time to check in,

Well since I boosted the car it's been running for maybe a whole 3 months. Unfortunetly I've ran into my biggest problem yet, started hearing a tiny almost grinding noise every few minutes. I got the car home and now have finally had time to look at it, we've discovered the tranny had leaked out all its oil, we filled it back up and test drove and it was leaking quite a bit. We checked the tranny oil again only to find little metal peices coming out of the tranny.

Well at this point we've pulled the tranny out and sure enough there's something that went horribly wrong inside. We don't know what has gotten shredded up, hopefully not the whole gearing but whatever did cut one of the seals which gave us the leak. My father thinks it was the LSD but we haven't cracked open the tranny yet. I'm to scared to see what I'll find.

You better off finding a used tranny. Rebuilding will be similiar in $$$.
Good luck tho...and try not to break the bank on your hobby tho!

Yea I've been looking around for a used tranny. I really need a new lsd also as I'm getting serious to get this car back up and running reliably with 300whp. I'm leaning towards we installed the lsd wrong which fk'd it up so I will most likely rebuy another obx lsd and take the transmission down to a transmission shop to get it done right.

I pray to God nothing goes wrong with this OBX this time. I swear we put that LSD in right, we followed step by step with a youtube video that a h-t member posted and it went in so right.

New used tranny - $500 - $800
Another OBX LSD - $400
Turbo Rebuild - $200 Minimal (shop quoted me earlier today)
Full 3" exhaust - $400 - $600? Really I have no idea what they are going to charge me but that's what I've heard.
Retune - $600
Total - $2,100 at best. *Long drawn out sigh*

Possible great news, we pulled apart the tranny to find a crap ton of metal fragments all over the tranny but it's possible that it was just part of the bearings that some shop pressed on.

Crossing our fingers it wasnt the lsd itself.

Ok I've decided to fix it the right way this time. Honda dealership techs were very helpful and told us the only thing that they thought was messed up were the bearings. But we were also told that it's possible some of the small metal shards could have ended up in the gear trees oil passage ways. So we decided to bite the bullet and let honda deal with the tranny, they cleaned it all out and checked it all out then reinstalled the obx lsd the right way with the bearings pressed on the right way. We now have the tranny fully done and put back together.

Now onto a longer story. *takes deep breath* My father was down in Pheonix searching for a clutch plate and was directed from one performance shop to another until he ended up walking into one of Full-Race's manufactoring shops (a company he hadn't heard of). Well after talking to one of the guys up front about my setup the guy went back and got the owner. He said they ended up talking about what I should do with my turbo setup for over an hour and got lots of info straight from the top guys there. Cutting to the chase after ALOT of talking to them personally and getting incredible discouts, I just now ended up walking out of there with ...

A/C Ramhorn
New Tial 44mm W/ 10 psi spring
3" Downpipe
3" Exhaust

Full-race products arent the cheapest stuff we all know but with the level of customer service and quality items I simply couldn't say no. And it's incredibly likely I will be back in there soon looking for more parts. I did have to buy a new wastegate as mine was a generic off brand with a different flange then on my new Ramhorn, but it's nice to have a real tial wg now.
Great staff + incredible products = me broke \:\)

I only have the Ramhorn now as they are making my downpipe now and waiting on the Tial WG and exhaust to ship in from their Cali shop. I'm super excited to get this civic back and on the road as it's way past over due. Let me know what you think.

Got retuned last Saturday after a few upgrades on the car at Locash in Phoenix.

Parts in red are my new upgrades since last tune.

Stock B16A2
Block bored .20 over
SRP 9.1:1 Pistons
Eagle H Beam rods
All seals and gaskets are OEM Honda.
GSR Cams
Megan Cam Gears
Clutch Masters Stage 3
Turbonetics t3/t4 .57 trim .63a/r (Bad Bearings) ---> Turbonetics t3/t4 .57 trim .63 a/r (Brand New)
Blox log manifold ---> Full Race A/C Ramhorn
Cheapo Wastegate 11 PSI Spring ---> 38mm Tial Wastegate 10 PSI spring
Greddy Bov
RC 550cc injectors
2.5" Downpipe ---> 3 Full Race Downpipe
2.5" Exhaust W/ Catalytic Converter ---> 3 Thermal Research and Development Exhaust no Catalytic Converter
Drag i/c 6.5 height
Hondata S300
Stock Radiator Fan ---> 13" Spal Puller Radiator Fan
Stock Condensor Fan ---> 13" Spal Puller Condensor Fan

Car more then a year ago got 251 whp / 191 tq. Locash got car to pull 277 whp / 200 tq with new upgrades.

It was around 110 degrees in Phoenix so VERY hot day. Locash also said it was only running at 9 psi because we moved the wastegate vacuum line down to the charge pipe before the intercooler inlet. So we may may the vacuum line back to where we had the first time to get the extra psi.

I would have loved to see a hard copy dyno sheet of 300whp. Hard to shallow the fact that I put 3k into the car for 26 whp even though I know it has gained more then that. I'm having huge regrets I didn't throw a 12 - 13 psi spring in, still don't know what I was thinking when I decided to lower the spring on second wastegate. \:\(



I'm still at a point where I think my numbers are quite low... even for 9 psi / 110 degrees. Going through these B16 Turbo Setups .

Why did you stop at only 9 psi?

I would move the w/g reference back to the intake manifold for one. Also, keep in mine, my rods/piston b16a2 made 450-500whp on 21-25lbs for almost 4 yrs. Driving April-October each year.

We are moving the w/g line back up to the manifold. Like I said I really wish I had a 13 psi spring in it now w/ boost controller but now we just got tuned, I can't bring myself to paying another $450 just to raise 4 psi or so... even though I want to very bad.

The small spring was surely a mistake.

Still can't drive the car as these poor civics have such a ridiculous theft rate. Especially here in phoenix az .Waiting on an alarm system ... can't wait to drive it even if its only 270 whp aha .

You spent 3k for a few whp, whats another 450lol. You can get a manual boost controller if you don't want to spend the coin, be had for less than 60 bucks, even make a generic one for a few bucks, lol.
