I have a 99 Civic Si with a stock block B16A2.

Mods:
Skunk2 Intake
BOSCH 440cc Injectors
Chipped and tuned OBD1 ECU
TSI GT25 turbo set up @ 8psi
Stock internals
Block head gasket is in good condition with no leaks.

The Issue:
I have been breaking in the turbo for about a week now, keeping the pressure less than 5PSI for almost 800 miles, the car was running good and I ran it for about 45 minutes pushing 8psi...

After running out 2nd and 3rd gear, I pushed in the clutch to coast and the motor stalled out and was smoking like crazy out of the catch can.

The car wouldn't restart easily and after about 20 cranks it started and runs like its down a cylinder.

It does not clank or tick, it just sounds like its puttering.

Is there a common issue like this after a turbo setup on a B16?

Thank you for your time!

Lesson learned. Never run on a basemap. BTW turbos don't need to be broken in.

How were you monitoring oil pressures and air/fuel?

That's what you get for not running with a proper TUNED EMS.

Pull the oil pan and look for shavings. Do a leakdown/compression test. maybe even pull the head.

Was the car tuned?

No. Just run on a basmep.

It was a base tune for use with the 440 injectors.

I have a oil pressure gauge and it has satyed at 50-70PSI. I have a stupid narrow band, yes I know I need a wideband, but it has been running rich.

That thing doesn't tell you anything. Regardless of the stupid readouts. That's why they call it a lightshow.

Are there any CELs?

Brettw

The only CEL is for my missing downstream O2 sensor.

Pull the plugs and inspect them. While the plugs are out perform a compression test

I probably already know this answer, but were you running a wideband atleast, I highy doubt you were datalogging any of this...

Brettw

No and no.

What do you think?

Brettw

I am going to get a compression tester this evening.

Turbo, basemap, no wideband...there's a right way to do things and there's shortcuts you just don't take. If you're going to skimp on tuning AT LEAST get a wideband to show you what the engine is doing.

Do a compression test and then check the oil and coolant.

Generally-
Lack of compression: most like headgasket or cracked sleeve, should see oil/coolant mix
Clanking: chewed up a bearing somewhere, should see metal in oil

I wouldn't define any of these "blown up" as all are generally salvageable.

Personally? Driving around on a basemap without monitoring anything is reckless/dumb. But we all do unwise things at somepoint. I'm thinking either busted ring land from detonation or melted piston.

Brettw

I had the car tuned at a local dyno with the 440 injectors right after I had it installed.

I'm confused. Are you running a basemap or is the car tuned? HOW was it tuned?

Did everyone miss when he said "stock internals"??..... why would you do that to yourself and waste all that time and not do it right?

doctorake

so was it a base tune or was it dyno tuned?

kyden

stock internals are fine to use for under 350whp.

OP: your motor is fubar.

^^ Agreed Marc
This is a common occurance when people dont do their homework and leave tuning out of the equation.
You cant leave it to chance that when adding boost that the basemap covers all the tuning areas.
There isnt such a thing as plug and play when it comes to this.
Just about every aspect of a tune has to be scrutinized and tweaked so the car runs perfect as possible.
Too rich, too lean, not enough timing etc...

Er. That turbo and that little PSI is absolutely fine. Stock B-series can handle 300hp easy. I think maybe you need to educate yourself a bit more.

doctorake

We saw it, we know what stock internals are good for in terms of HP.

speedooo

Because nobody has ever safely force fed a stock b series motor...ever.

Brettw

It was dyno'd.
