Any users of the Alta Turbo Inlet Tube for JCW here?
http://altaperformance.com/i-1400715...bo-engine.html
Looking to replace my stock JCW one that failed for the second time. Unfortunately it took my turbo with it. I don't really want to change anything else at this time so I'm wondering if all the other parts will hook up? Turbo is being sent for a rebuild upgrade so I have a few weeks to decide.

 

LOL, must not be a popular choice for JCWs.

 

I have one and it works just fine, especially with my DoS intake. The crank case vent coupler pops once in a while so make sure to secure it well.

 

Can I use my factory intake and the tube going to the valve cover? How are the o-rings as far as needing to be replaced?

 

I haven't used it with the factory intake, but I am sure it was designed to work with the stock air box. I have never removed it in 2 years so can't tell you the condition of the o-rings.

 

Thanks, response much appreciated. I'll call Alta Monday and see about ordering one. Do you think there is a performance increase over the JCW stock? I know they say there is and I've seen some fancy curves. The turbo rebuild according to the shop should add 30 plus. I never really intended to start increasing horsepower but it seems between economy and practical precaution I'll end up with some.

 

I got turbo off yesterday for shipping and took the exhaust manifold off today. Time to inspect and clean.

 

No, I never felt any increase. Luckily I found my tube on here for cheap. I don't think it's worth the full retail price to be honest. I will be going down this road soon too. My turbo is at 80K and I feel it is time to rebuild. Who is rebuilding yours? Make sure to get a new downpipe too if you can or maybe even go catless if emissions is not an issue.

 

Mine had 70K plus. I suspect I was hearing the turbo being a bit off balance. I also suspect the vibration is what caused the hose to come loose. It was a disaster waiting for an opportunity. I'm not inclined to trust another stock inlet after this. I like the idea of an aluminum inlet tube.

 

I sent it yesterday to G-Pop Shop.

About $700 for a rebuild upgrade is what I was quoted.

 

Don't think I can go catless or really want to at this point. I've read people say it should be replaced or refurbished. Realistically I could probably afford a refurbish, but not a new one.

 

Still cleaning up and gathering parts. Here's the tube!


The old and the new!



The big difference! Of course the original is minus a rubber seal.

 

Here's what's left of the factory seal.

 

It's in!

 

Very nice!

 

It really went in easily. I can't see any way this will come loose and even if it did there is no seal for the turbo to swallow.

 

Nice sikami.

So you're down in the Houston. And you found this turbo place in Arkansas? How'd that come about?

These guys good? They were certainly cheap. 7 bills for a turbo.

Curious how you're burned out after what? 70k?

Mine is at 70 but runs fine. Of course I baby the oil on it.

Notice a big diff with the new intake pipe and rebuilt?

And you installed yourself? Replace the intercooler?

Notice you didn't add a thermal blanket or heat shield over the compressor.

How long did it take you? Thanks

 

I'll put the AR file as I'm in Dallas and Cali. There's a place in Phoenix that's so suppose to be rad on turbo rebuilds too. JR I think.

 

I put in a turbo blanket. I believe there was a thread here that mentioned the shop. I'll see how it runs next week. My turbo swallowed the inlet tube seal. It was my second factory inlet tube. The first broke at the turbo and seal. The second started to come loose as the seal was getting bad. I tightened back up and some months later it was loose again. Naturally I tightened it up again and it almost immediately came loose and sucked the seal in. So, rebuilt turbo, Wagner Tuning intercooler, Alta aluminum inlet tube, WMW resonator delete and noise maker delete. Turbo probably had plenty of life in it. I did polish the exhaust manifold and had the shop work the turbo a bit too. Next week I'll replace the water pump. Next month brakes. It's been a month total.

 

wow lot of bucks spent on that car.

You should read JR's advice on caring for a turbo.

Def time it out. Don't just shut down like a vacuum cleaner. They give the whole reasoning. Makes sense.

So does it run way better or just good?

 

I'll know next week. I'm putting the water pump in first. Feels good, but then I've always been happy with her. I think I'll re-read those tips on turbo care. I usually let it run a bit before turning off. I sit in the car and read my phone. Lol.

 

Aside from the turbo rebuilt it was just parts costs. It came for a lot less than if I would have had someone else put in a JCW replacement turbo.

 

Yeah I do 3 min. Get's the exhaust heat down and supposedly doesn't fry oil on the bearings. Oh it was JM Turbo, not JR. lol Must have been thinking of Dallas

Just checked JM's rec. 5 - 10 min.

 

I try to do at least five. Might see about doing closer to ten. From his article:
"To prevent back pressure do to turbocharger failures just, idle your car until the EGTs get below 900deg F (about 5 to 10 min, EGTs can be read off of Bank 1 sensor 2 on the MC N14 and N18 engines), and to prevent the valves from coking up with oil walnut blast them and install a cap to block off the rear crank case ventilation. Once the rear crank case ventilation is blocked off they will not likely coke up with oil again as quickly."
Not sure exactly where this ventilation he wants blocked is. Have you done it and where is it?
