Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Added
 

Ok, been away from the scene and my car for close to 3 years(moved across the country and had to leave my car there), been working non stop and haven't played with Honda's in years, so i apologize for any dumb questions, i honestly used to know what i was doing haha.

Ok, i've got a 90 Civic Si, b18b, obd0 dizzy and ecu. Running an SVO Mustang Turbo with a cheapo ebay ram style manifold, stock internal wastegate, fmic, turboxs Bov. DSM 450's, oh and custon 2 1/4 downpipe and full exhaust. For fuel management i'm using Turboedit, and i've made own basemap, but it seems to backfire quite a bit, so i tried ng48-PR4tune-19.bin from the Bin directory and that seems smoother but still very rich.

So, as for issues,

1. I'm only getting 5 psi max, with the vac line hooked up to the wastegate i get 4 psi, leaving the wastegate unhooked i figured i should get infinite boost just to see if that was the issue, however i still only get 5 psi. Also, i'm only getting the full 5psi at 5k in second gear.

2. It's running really rich, at idle, and smoking all thru the RPM band, engine alone worked flawlessly before, and a buddy used the turbo for a couple months and it never used oil.

3. I get no power under 5k Rpm, like slower than before the turbo, and even when i'm finally at full boost it's by no means impressive. I assume that the wastegate may be leaking, could this cause the issue, if so could someone explain how a helper spring exactly would be installed?

4. I've got a rs232 adapter with 4 wires for datalogging, when i bought it, it was the thing to use, now all i can seem to find is this nokia cable? Can i still use the adapter that i have, will it work with turboedit, and if so is there a write up somewhere? I've serached here and pgmfi and can't seem to find any luck.




I'm not getting any codes, and i can't go WOT any higher than 2nd gear to test anything as i have no Reg and no insurance and can only zip up and down my subdivision, and don't want to pay for all that until next summer but i'd like to get it finished before winter. If anyone has any ideas that may help me out, or point me in the right direction that would be great. I'll try to get a ton of pics of the setup and post em up when i'm not working so much.

Re: Finally on the road, few problems, lots of questions.
 

Ok nog where are the cliff nots?

Re: Finally on the road, few problems, lots of questions.
 

Cliffs,

No low end power
Can't get more than 5psi
Running rich
Doesn't reach full boost till 5k RPM.

Re: Finally on the road, few problems, lots of questions.
 

do you mean he didn't have the oil hooked up to the turbo???

Re: Finally on the road, few problems, lots of questions.
 

No sorry, i mean the seals seem good, it never burned or leaked any oil.

Re: Finally on the road, few problems, lots of questions.
 

Seems like your wastegate isn't fully closed therefore only allowing the 5psi of boost. Mine came loose and I was getting the same results. As far as no low end power, you're running pig rich and you don't have boost.

Re: Finally on the road, few problems, lots of questions.
 

Ok, so would a helper spring take care of this issue? If so, how do i hook it up, do i just anchor it on the turbo housing where the actuator bolts on, and then onto the flapper?

Also, can anyone point me in the right direction for install of that rs232 adapter for datalogging?

Re: Finally on the road, few problems, lots of questions.
 

Make sure your wastegate isn't binding, which it sounds like it might be.

For datalogging, look into one of the USB datalogging cable + header kits from Xenocron.

Re: Finally on the road, few problems, lots of questions.
 

Check for boost leaks and exhuast leaks ,Their might be a crack in that ebay manifold. An exhuast leak before the turbo will definatly cause it to not build any boost. as for it being rich you have a chip burner ,tune it.

Re: Finally on the road, few problems, lots of questions.
 

Re: Finally on the road, few problems, lots of questions.
 

I know i've got no exhaust leaks, and i've tested the wastegate with my air compressor and it seems to open and close freely( i originally thought it might be binding as well as i had to bend it to get the appropriate legnth). As for tuning, i realize i need to tune it, which is kinda why i was asking about how to install that adapter, i just need to know if it's still compatible with Turboedit as i already have it assembled, just not installed. If i have to try something else i will.

Re: Finally on the road, few problems, lots of questions.
 

bad turbo shaft + shitty tune = no go

Re: Finally on the road, few problems, lots of questions.
 

Turbo is fine, as i said it ran in a friends car with no issues, however he used an aftermarket external wastegate

Re: Finally on the road, few problems, lots of questions.
 

:y

Re: Finally on the road, few problems, lots of questions.
 

stop post whoring faggot !

Re: Finally on the road, few problems, lots of questions.
 

Ok, so i haven't made much progress, other than fixing a small leak on my ssautocrap manifold and fxing the vaccum line on my BOV, still even without the hose attached to the wastegate i can't get anymore than 6 psi and it's still slower than it was before the turbo.

Maybe i'm retarded, but the car has been sitting for a few years, stored inside the whole time, and i put in 91 Octane before i put it away, is it possible that it could just be bad fuel making it run so poorly? It seems to idle fine and doesn't run rough or anything, it just doesn't have any power.

Re: Finally on the road, few problems, lots of questions.
 

....Id replace the gas to start..

Re: Finally on the road, few problems, lots of questions.
 

PS, Here are some pics for motivation. I'm ------- stumped here

Re: Finally on the road, few problems, lots of questions.
 

Couple ideas I could think of at the moment.


Check intake charge pipes and B.O.V. to make sure they aren't leaking.


Check all vacuum lines. You could be running rich with just one vacuum line unplugged. Happened to me, and it ran pig rich. Or maybe you need to tune it through your software. I'd start with the basics first.


Maybe try making a manual boost controller for the waste gate.


Is your waste gate adjustable? Shorten the rod if you can.


Also, good quality pics posted could help. Maybe someone on here can pin point a problem. :)

Re: Finally on the road, few problems, lots of questions.
 

Ok, I filled it with 94 Octane fuel, and fucked with my maps a little more, now i'm getting 10psi, at about 7k RPM. It still runs like ---- tho, seems to take forever to rev, and is still slow as ---- until i get over 5psi. Here are some pics and i took a couple vids of the car running, with the camera pointed at the Tach and boost guage, maybe someone can notice something that i can't.

I'd make sure that vacuum line to the B.O.V isn't pinched like that at all. Just run a little longer line.

How's that chow ming manifold holding up? Did you brace it?

What are your plugs looking like? Gapped at? Kind?

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Plugs are NGK ZFR5F-11 and are gapped at .044".
I've already fixed the vac line to the BOV, the manifold is a hunk of ----, however i got one of the later ones that came braced, but i did end up rewelding where teh collector meets the flange.

I'm almost to the point where i'm gonna haul the turbo off this heap, part it out and be done with it. This is getting really frustrating.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Added
 

ECU might be ----

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

this would be the first thing i would address.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

I wouldn't give up on this ----. You're almost there.

Trying lowering your gap on the plugs. I put mine down to a .35. It may help.

You may just need a tune.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Would a fucked turbo cause this? It seems ok, smokes a little, but it spins freely and doesn't have a ton of shaft play.

The Vac line to the BOV has already been fixed, and the plugs are brand new, i'll try regapping them tomm.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Added
 

Try pressurizing your charge piping to see if you have any major boost leaks.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Did that, found a small leak, the turbo leaks a little oil into the intake side, so it's easy to spot a leak when there is oil on the charge pipe.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Timing?

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

That's my next step i think, however the motor was pulled from a running car, and nothing has been touched other than swapping the dizzy, and it's lined up on centre. I'm gonna try cap/rotor and new wires as the old ones are tired. If that doesn't solve my problem i think it's time for a Stock N/A b16a

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

I still disagree with your last statement.

You do that, and it will always trouble the ---- out of you until you finally find the problem.

Try this.

Go over the complete basics.

Check everything, all connections, vacuum lines, etc.

Maybe, you could try swapping in a stock ECU?

Pull the plugs. How do they look? Did you re-gap them? If so, did it help at .35?

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Added
 

Check your base timing with a timing light.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Well, i think i may have found the issue, taking the advice and starting with the basics, i started troublshooting it as if it wasn't boosted. First thing i did was take off the cap and have a look, here's what i found.

Attachment 23785

There is corrosion on the pins in the dist cap, and a weird almost salt like substance built up in the bottom. I went to the parts place to grab a new cap/rotor but i got the wrong one, i'll have to swap it out for the right one but i think this might be it, i guess this kinda ---- happens when a car sits for almost 4 years.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Agreed, that may be the culprit, corrosion isn't good, but if you see a crack that will definitely tell you that it's no good.

It happens man, but I'm glad you are still hanging with it. :)

Have you changed the fuel filter?

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

ohh my god i laughed that thing was so slow, keep us updated and hopefully you cant get it running right, dont give up just yet

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Well, i changed the ------- cap and rotor, and no difference whatsoever. No i haven't changed the fuel filter, i guess that's the next step.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Added
 

Damn don't give up you'll get.And a far N/A geos i'll NEVER go N/A again,I'm to addicted to boost >:D

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

I'd love to be able to datalog and see what the ---- is going on here, but as per my thread in Engine management, i cannot for the life of me obtain any usefull info from Freelog other than TPS=-11 and o2=10

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Added
 

I would like the guy said, get a stock ecu and plug it up with stock injectors to see if it fires and drive without boost to see if it works. If its the same ---- with the stock ecu than its probably timing. I don't know about TurboEdit but if that usually happens to me on Crome its usually the fuel multipliers. Like they say every motor is different...what worked for another guy might not work with your engine..just fiddle around with the tps enrich and offset multipliers if TurboEdit has it.

Re: Finally on the road, few problems, lots of questions.(UPDated, Pics/Vids Add
 

Ok, well i just got off the phone with my buddy who originally owned the old motor, the engine is a B18b, however i'm running obd 0 dist and intake manifold etc. He said he thought the b18b timed up differently than the b18a, so if i'm using PR4 maps from a b18a, then the timing is obviously going to be off. Does anyone have a hanes book for a b18a, that can gear me up with timing marks and instructions?
