The Build - A GT2871R build documentary

[M-Hood]

I was thinking bigger. go big or go home..... lol


Spending 1300-1500 on a turbo to get not much more out of it is hard for me to justify. I was looking to leap to the 30R size

But only go big enough to get the power you want while still keeping a good power band. The 5152 is pretty much right around the size of a 3076r, the 3076 is a 5447 which means the 5152 has a larger exhaust wheel but only a slightly smaller compressor wheel.

[MmmBoost]

definitely. I don't want to ruin my car or turn it into a dog in traffic.

I would actually consider going higher compression with a big turbo and running less boost.

[Charlie240sxt]

If you where to go that route would you think about switching fuels???

[Dan[FN]6262]

Sheetz better hurry the hell up and start selling E85 in all of PA, other than just the west side. I would love to run on E85. Closest station to me that sells E85 is friggin an hour away.

[MmmBoost]

Never going to run anything other than gasoline.


I drive my car all over the place.....camping...mountain biking....snowboarding...traveling... I would not want to have to hunt around for ethanol in buttfucknowhere.

You also get way less miles per tank full on E85. Just think if your car gets 400 miles per tank now its only going to get about 280 per tank running E85. Would have to add a 2nd tank to the car. lol

The crank bolt was a filthy whore today. I knew it was going to be bad taking out the ARP bolt.....fuck me.... I sheared off two 1/2-3/4" adapters. I ended up having to make a run to the store this morning before I even got started so I could pick up another adapter, a cheap socket, and a 36" long 800 ft-lb capacity breaker bar. I fired up the TIG and welded the socket to the adapter and gave it another go. It took all 160 lbs of me bouncing on the end of the breaker bar with my feet off the ground to finally get the bolt to crack loose.

Other than that.....the day went pretty well. Got the Integrated Engineering dowelled crank pulley installed. Put the crank bolt back in and torque the fuck out of it. Head gasket went on, torquing the head bolts went smoothly....timing belt went on... One thing I did notice about the head bolts though....after the final torque sequence I decided to go back from bolt #1 and check the torque and I was able to turn the first few bolts in the sequence a tiny bit after getting the last bolts torqued. So after going over all of the bolts again with the final torque they were all even. Might want to check that out next time you guys are doing a head install.

All that's left is hooking up all the hoses and installing the intake manifold, then I can put the front clip back on.

[Dan[FN]6262]

Victor Reinz headgasket? I'm sorry. ....

[jaychen]

Victor Reinz headgasket? I'm sorry. ....

you have a habit of making me feel nervous Dan,

what is wrong with Victor Reinz headgaskets?

[Dan[FN]6262]

you have a habit of making me feel nervous Dan,

what is wrong with Victor Reinz headgaskets?

lol usually nothing. I've installed a bunch of Victor Reinz HGs that are holding up just fine.

I've seen a couple VR HGs that were way different thicknesses from one end to the other.

Every Elring HG that I've had were always within ~.02 from one end to the other.

[MmmBoost]

The headgaskets are stamped out of gauge thickness sheet material. There may be variances in thickness from one end to the other before the gasket is compressed but after torquing down 10 headbolts to 80 ft-lbs I can't possibly see how there could be a measurable difference in thickness after crushed......nor would you even be able to get in to measure it to check.

[Dan[FN]6262]

lol I know, I just like fucking with people. Like I said, I have to have one fail that I've installed

[MmmBoost]

Looks like all that turbo talk jinxed me.


Finally got the car running tonight after having to charge the battery for a few hours to get the engine to spin fast enough to fire.

Once it fired the whole place filled with smoke. I figured it was just the smoke burning out of the exhaust and off the manifold......etc.... not so much. I think along with my head gasket issues......it managed to take my turbo out with it. After reving the engine a few times the whole intake has fresh oil squirted all over it......and the smoke in the exhaust is not getting at better. Either my oil pressure is through the roof for some reason (which I doubt) or the oil seals in the CHRA are gone.......or at the very worst piston rings fucked and the crankcase is being pressurized.

I'm kind of at a loss as to where to go from here.



.......fuck....my....life....



Who wants to donate to my new turbo fund?

[613B6]

Do a quick compression check to rule out the rings, but if your getting fresh oil in the intake its probably your turbo..make sure you return line didnt colaspe or get kinked/crushed. And check for small things like making sure your restricture is still in place. Sorry to hear.

[SleeperAvant]

Damn sorry to hear Chris!....And yeah do what Sam said. Hope that it pans out without being more costly....

[Wet0willy01]

gulp....

I did the exact same thing to drill my second hole.

[MmmBoost]

I checked compression before I got the engine started because I was having problems getting the engine to catch. The numbers all came back pretty decent for a cold engine.

55
72
58
70

I can't really check compression and get accurate numbers because I don't really want to run the engine the way it is. It's a smoke show. Not to mention if it's something really bad I don't want to make it worse.


The oil restrictor was not touched.
The oil supply line is still the same one in the same location.
The drain line is not kinked.....I guess I'll take it off to be sure it isn't plugged but I don't see how. It's a -10 hose.

[M-Hood]

Odd that it is smoking now but wasn't smoking before you had to work on the car.

[MmmBoost]

the last day I drove it was smoking......but not this bad

[M-Hood]

But was that because of the cracked head or because of the turbo and have you checked the manifold to see if there is oil inside of it?

[Dan[FN]6262]

I'm glad to see that you did get it started, but it fucking sucks that you're having this issue now. sad panda

[M-Hood]

But have to wonder what was causing the car not to start seeing that a bad turbo isn't going to cause that.

[MmmBoost]

Battery was VERY low.


I checked EVERYTHING


I had fuel
I had spark
timing was perfect


The engine just wasn't rolling over fast enough. I let it charge for an hour and a half and then it fired.

[SleeperAvant]

Still smoke?

[MmmBoost]

Still smoke

[Dan[FN]6262]

I think its trying to tell you that it wants some Triple Ball Bearing and Billet goodness........

[SleeperAvant]

Chris, when you say the smoke is coming out of the exhaust, where in the exhaust system is this smoke coming from? The CHRA itself?

[MmmBoost]

smoke is coming out of the exhaust. the car is burning oil like someone is dumping oil into the turbo.....which is exactly what's happening. my freshly cleaned turbo is full or fresh oil on the cold side

[SleeperAvant]

Stupid question, but what is the oil level at on the dipstick? And is your catch can plumbed into the turbo inlet pipe?

[MmmBoost]

Stupid question, but what is the oil level at on the dipstick? And is your catch can plumbed into the turbo inlet pipe?

Is that a serious question?


And no the catch can is vented to ATM.

[SleeperAvant]

Nevermind then, sorry for the stupid question.

[MmmBoost]

It's all good.....I appreciate the help, but it is a little more complicated than just putting too much oil in the car.

[Dan[FN]6262]

[M-Hood]

Well if it is coming out the compressor housing then the seals on that turbo are done. Some oil on the compressor inlet is normal, not if it is dripping everywhere.

yup. pretty much my thoughts.


Now I need to figure out what to do.


new CHRA
GTX2867R
or COMP CTB/CTS of some kind

[SleeperAvant]

Sick.

[M-Hood]

Well there is more to choose from in the CT2 line and most likely better priced then a GTX. With the GTX your still stuck if that one goes bad while the CT's are serviceable.

[MmmBoost]

I do like the serviceability of the Comps. I don't understand what Garrett was thinking with the DBB CHRA's being untouchable. It's fucking stupid....


I need to stick with the 5-bolt pattern T25 though. After all that money and work on the external wastegate and exhaust I am not flushing that all down the tubes.


I was considering sending in my housings to Comp and getting them to build me a CTB-5558 or 5560

[SleeperAvant]

That would probably be the best bet since you're keeping the housings but having all the internals re-done.

That wont be a problem putting the CT into your T25 housing so that you don't have to change any of the exhaust setup or wg setup on your car. Basically just like they did on Pete's 5 bolt housing which was a T3.
