New Turbo Smokes after shut off

[MilitaryTalon]

Alright I finally got my new s256 on my car and I started it. The car idles very rough and bogs bad if I hit the gas. Also when I let the car warm up and shut it off there is smoke coming from the turbine housing as well as from the tail pipe (white smoke) I'm not sure what to think.... Any suggestions?

By the way it idled fine yesterday and I had to jump it off today and it started acting this was. The only thing I changed was I tapped my lower IC pipe to hook up my MBC

Based on your profile mods, i would suggest you swap out your injectors for bigger ones, as well as a walbro 255, afpr, and get yourself a tuning device such as dsmlink.
Also make sure your spark plugs and spark plug wires are in good shape, or if they have never been replaced, do so now, and replace your fuel filter if you haven't already done so.
Last but not least, check for boost leaks. Let me know how it goes when you get these small tasks done.

Plugs and wires are brand new and I did put a new walbro 255 in. I will check for boost leaks. What could cause the smoke????

720 PTE inj should be good right?

Where are you sourcing your oil supply line from?

My oil feed is from the OFH and I used the oil feed flange supplied with the turbo from Bullseye. Could I be getting to much pressure? If so how can I tell and 2 how do I fix it?

How would I install the restrictor if is needed? What size and where would I get one. Also how can I tell what pressure I am getting at the turbo? Sorry about all the questions but I'm flying blind here.

Alright I came home from work today and attempted to start the car. The batt was dead, I tried to jump it off and it had a real hard time starting, I had to let it charge for at least 20 min on a brand new Optima batt. When I finally got it started I had to constanly play with the throttle to keep it running. It sputters really bad when I press the throttle. I kept it running long enough to heat up a little and the turbo started bellowing whit smoke from the exhaust side. I turned it off and let i cool down and there is no shaft play. I am very confused, I have a new fuel pump, new plugs and wires and it is acting like it is starving. What in the world is wrong. I was suppose to tune this weekend but I can't even get running for more than 2 min. I need some help ASAP

255walboro with no AFPR could account for the poor idle if it's overrunning your stock fpr, causing a rich condition.

I tried to attach an idle log i don't know if it worked or not

Does anyone see anything wrong? The file is to big to post the whole thing. So here are a few secs of the log

Well I have to take a minute to give a shout out to RRE... I called them yesterday and talked to Sam trying to get some advice. When we couldn't figure ti out on the phone he told me that he would come down here tonight to help out. That is relly good customer service if you ask me. For a shop to come 1hour + to come and help someone that has only bought a few items from them on such short notice. Thanks guys I appreciate it.

Hopefully we can narrow this problem down and it's not anything major.

Any tips would still be welcome.

Huge props to Sam from RRE, he drove down last night after he got off at 8:30 and drove 1hr 15 min to come help. We had it running in about an hour then just sat around and talked DSM. So I just wanted to make sure RRE's customer support was given credit my notably Sam. Hopefully we can get it tuned tomorrow and be ready for some speed.

That's "WOW" customer service! hopefully you bought all your parts from them

 

[MilitaryTalon]

I bought most of them from them, but after this I will be throwing all of my business their way as well as recommendations.

so what was the problem

 

[MilitaryTalon]

Come to find out, after searching on this forum for posts from the previous owner, I have an EPROM ECU with a DSMCHIP and it is chipped for 660cc inj. Since I was unaware of this I had my ECU+ set for 660's, So it was over compensating adn flooding the engine. As for the smoke from the turbo when I finally got it to run for a while it burned off all grease and oil residue from the outside and now runs like a dream. Now I am just waiting for a tune before I put the pedal on the floor.

Thanks guys for the help I'll let you know how she does.
