Common in the Camaros for sure.

UPDATE: I called and talked with him. He said it started up fine this morning, and when he got over to the local shop that it started up fine for them as well. After a hr or so, I called him back again to find out the results and he was told that the MAF sensor bolts were loose and seemed crossed threaded. So I talked with my techs and they told me that the MAF bolts used were the ones that came out of his CAI. They did mention that the bolts were tight when screwing in the housing. We use the Cast Aluminum GM Housings in our piping. Not sure if when the housings are welded on to the pipe that it may have distorted the threads a little or maybe a casting flaw inside the threads to cause the bolts to cross thread. Also I asked him if the local shop that looked at this and found the issue actually charged him for a diagnostic fee or anything. I told him I would pay for any fee and he said no. we are also checking each individual MAF Housing and running a thread tap thru them after they are welded to make sure this never happens again. Sorry for the issue, and glad it worked out.

Easy fix. Definitely explain the on again off again symptoms.

[grocerygetter]

Yup. See... Cold side leak.

Could also be a dirty MAF,it may be oil soaked from the turbo bearings being flooded and passing thru the inlet tube,and if thats the case it'll just be a matter of cleaning the MAF and replacing the oil retrictor to the next smaller size on the turbo,I delt with that early on in my build just something to look@...Good luck and keep us updated.

A journal bearing turbo doesn't need an oil restrictor.

My Technician told me exactly what he did and how it went together. I have no reason not to believe him. Thanks for your concern though, I will take it into consideration.

Glad it was a simple fix! Now go enjoy it!

[SS_Diaz]

Well....... Had a couple good starts, and it did it again tonight after i left the gym. I drove to a local autozone turned it off and back on and still the same thing. Bought a new aftermarket MAF from autozone but didnt fix it. :( I'll give you a call tomorrow chris.

I have seen oil retrictors on a journal bearing turbo but was because of big oil supply line,And I just assumed it was a bb unit since Chris has been using the comp's,but I guess everybody don't wanta spend the money on bb setup,or water cooled or a billet wheel for that matter,hope he can resolve the issue soon,surely there sum good help in carolina

Comp has told us the diameter restrictor to use on there journal bearing turbo's. We have had to use them in the past on there journal bearing turbo's due to the high oil pressure on some of these engines. The turbo on Diaz's car is a ballbearing and has a restrictor as well.

Chris

[LSX-80MM]

Yea Chris I thought so

[JLE58]

I didn't know he had a bb turbo I just figured it wasn't... Must be pushing alot of oil pressure to need one on a journal.

Chris, dont our kits have 80 lbs resized stock injectors? Is it possible that one of the injectors got messed up durring this proccess and is causing his issues by allowing air in the fuel system? I had a jeep once that would always run like crap until it got warmed up, injectors were old as hell and would leak down when the jeep was turned off.

Yes, they are all flow tested and pressure tested before they leave FIC( Fuel Injector Connection). We are actually checking the fuel pressure and leakdown of a vehicle here at the shop with the same injectors that starts normally, and its twin turbo's vs. the fuel pressure and leakdown that john is seeing.

Chris

[Chris-HPS]

UPDATE:

After talking with John and going over some diagnostics and the fact that the starting issue is not a constant issue, I have contacted FIC and after talking with them about the issue, we are thinking that there is a leaky injector or something else so we are having a brand New set of injectors overnighted to them. Hopefully everyone on this site will understand that sometimes issues arrive, however it is how the issue is worked with, or taken care of and that we(HPS) are doing everything possible to care of John and this issue that has occured.

Chris

[partymn]

Oh, hold up Chris dont be taken parts out of my kit to fix SS_DIAZ Camaro.

On a serious note, I hope that this fixes the issue. I hate seeing a man with out a properly running SS.

[rhunley14]

Speedmon that is a good read. In every proffession there are definitely crooks and people who do not know what they are doing. I will say this. There has been a slight problem with my build. Chris has been paid in full and he his gone above and beyond to make sure that things get taken care of. Not only is he getting it done, he is also putting in new axle and a methanol kit as well. If I did not think he was ethical or trust him, i would move on to another shop. Since the first time I talked to him till now he has always been a straight shooter and i would recommend people to his shop. I understand this is a forum and that you have freedom of speech but your off base here.

The Drama stops here...

Chris-HPS is a respected tuner and also a sponsor of this site.

Right here in front of everyone, and as stated by the OP, Chris has stepped up and taken care of the issues...

I believe that Chris probably talked to the shop the op took his car to before allowing them to make suggested repairs... to determine in his mind if they were capable of making solid repairs as suggested by Chris.

There is a subforum for vendor reviews, and this thread is not it.

Those of you who's posts disappeared along with the drama posts, I apologize... call it collateral damage...

Any further posts bashing vendors, wringing hands, playing the devils advocate or doom saying will be deleted without further explanation and dealt with as necessary beyond that.

I speak from first hand knowledge that high level tuners and builders occasionally have to depend on others for what may be a temporary fix, or in some cases, a permenant fix... It is certainly not a slap on the tuner/builder/vendor... It is actually a tribute that they do follow up on and pursue the issues their customers have... No one builds these big mod cars without occasional issues; the proof is in the way it is handled after the fact... I contracted with my builder to build my car... not to be with me for thee rest of my life in case anything were to ever happen..

Last year on the way to the Fest in Phoenix, I crapped a turbo, and it took the other one with it from over spinning... My builder was ready to 1, get on a plane, 2, drive out with his trailer... I told him no, there was a builder/tuner from another shop.. I got them on the phone together and the guy that happened to be along with our group, made suggestions, and offered information based on his findings, but only did what my builder asked him to do... and he never charged me a dime for his time either... about five hours total...

Problem was solved, I enjoyed the rest of the time in Phoenix, drove the car 1000 miles home and then my builder went over it with a fine tooth comb...

All is good...

Chris has stepped up as stated by the op... so vendor trashing and bashing stops...

Thank you for this confirmation on the integrity of this vendor and forum sponsor...

But.. This is a privately owned and operated Forum, and as such, there is no "fredom of speech." We have rules and forums for specific topics and this is not the location for a vendor review.

Rhunley, Again, I appreciate this post and you certainly did nothing wrong, I just want others to realize we do have and will enforce the rules of posting, for the benefit of the site, the members and the vendors.

So what was the fix?

[SS_Diaz]

Thinking a leaky injector, Im out of town so the car is at home. The new injectors will be installed on thursday and hopefully its good to go.
