turbo manifold

[jlkon]

Hello everyone, haven't been on here in awhile. My MSP has been down for about 3 years now and its time to finally get her running. I need to know what my options are on dealing with a cracked turbo manifold. When she died, i was taking off from a stop sign in first gear and I heard a pop and it stalled. It would fire instantly but the minute i took my foot off the accelerator it would die. Got it towed to the house and i was able to keep it running as long as i kept it at 3500 plus rpms and noticed alot of carbon deposits coming out of the exhaust. Since then i have removed the turbo and inspected it. Nothing wrong with it. Then i took the manifold off and noticed some of the bolts missing and numerous cracks in the manifold. I have priced a new manifold from mazda. Yeah no 1600 bucks. I bought an after market one. Looks like i need to modify it to make it work on my car. Need to go for now, hope someone can help me. Thanks in advance.

as long as you baught an obx manifold for a 2 liter protege, it will prob work, but the exhaust will likely not mate up properly. you would need a custom downpipe at the minimum. bolt on solutions.. you pretty much only have the one choice with popes manifold but its pretty damn good from personal experience.

pop and dead might have been something as simple as a popped coupler or something.

The OBX mani likely has a T3 flange that will not fit the stock T25 turbo. There are options for replacing the stock mani or you can just have the cracks welded which is the cheapest option, replacement manis are around $600 new. Don't waste your time with the $200 ebay manifold it will crack the first day you have it on. Valk is right it could be something simple like a charge pipe popping off or a dirty MAF sensor, nothing that would keep the car down for three years!!

Thanks for the replies, greatly appreciate it. Everything from the turbo to the CAT was fine. I thought that the CAT was plugged which may have caused the manifold to crack. From reading around, a few people have had the manifold crack on them. I will check the MAF though. Oh and also I do have an adaptor that bolts on to the turbo to fit the OBX. I am attaching a couple pics' one is the schematics of the callaway turbo system and one is the OBX manifold like the one in my previous post but with an arrow pointing to a port. There are two ports on the callway manifold and one on the OBX. What are they? I really have to be honest. I went to UTI for 2 years and Mercedes Benz Training and you would think I could understand how this system works but im confused. Especially if the OBX manifold that bolts up to this engine doesnt have the same two ports as the callaway does. I know two lines bolt to them but wouldnt i have to modify the OBX so i can hook those lines up?

ok did my research. Guessing the other port is part of the recirculation valve system and i know now that the one on the front is for an O2 sensor. I guess i can have someone weld a bung for the O2 sensor and i can run an additional line from the port on the OBX (which i think is for a bov) to the line going back to the engine. Or get my old manifold back from my friend that has it because he was trying to find someone that could weld it correctly and get it fixed and put humpty dumpty back together again. Sorry, my cars not humpty dumpty..If i could get into my computer on the car i may be able to delete the O2 sensor. UTI Tuning class, loved it. I want tuning software for my MSP.. LOL

I need to get my mind back into this. I worked at MBUSA in Billings MT after I graduated from MB training in Houston TX and was let go 2 months after. I like working on vehicles, im just not fast at it. It takes alot of repetitive work for me to remember how to do things and in Billings that was not happening, yes i was getting good at pulling turbos out of sprinter vans cause i did quite a few of them. Other things it was one time here and there. They didnt give me a chance. Oh well... I didnt come here to discuss my personal issues, sorry. I just need some help getting my car back and running.

The mani should have a bung for the primary 02 sensor. The other flange on the manifold is for an external wastegate. You will need to cap it or remove the internal WG on the stock turbo and purchase an EWG and dump tube/weld the tube to the downpipe. The other port on the mani is for the EGR. Unfortunately the MSP computer has not been cracked and you cannot alter the tunes or turn off sensors like on some other cars. Best and easiest bet is to repair the stock mani, I had a local guy that is a really good welder repair both of my stock manis and they haven't cracked again.

Nice, Do you still live in Austin, my stock mani is with a friend that works for Porsche of San Antonio and my sister and mom lives in New Braunfels. Can you give me the contact info to the guy that welded that for you. Thats what my friend is trying to do, is find someone that can do a good job on it.

Yessir born and raised and no intention of leaving any time soon. The shop is called K&K Welding it's on south Congress just north of Hwy 290/Tx 71. The owners name is Jesus and he has repaired the stock manis on both of my MSPs and they are still holding up fine. Dude really knows his stuff about welding and materials and he is building a twin turbo Cobra.

Thank you sir for the information. Can't wait to get my car up and running, then i need to try and sell my current running vehicle, payments are kicking my butt. Hmmm. I think i have messaged you before about my car. Way back when i first had the problem. I was driving my brothers 09 Bullitt then.

 

[hornsfan10609]

Oh yeah I remember now, I still have my 09 Bullitt

 

[jlkon]

Awesome, I loved that car, it was actually my brothers and he sold for a jeep rubicon. I may be going through Austin in a couple weeks with a uhaul full of my moms stuff. Going to contact K & K tomorrow and see how much it would cost to fix the manifold.

I got a thunder v3 manifold laying around if you are interested.. it does have a crack that needs to be welded but that wouldn't be hard since its stainless steel.
