are you doing anything about the plastic intake manifold and non-return fuel line setup?

 

you dont need to do anything about either one of those with such low levels of boost. there was a guy that ran 22 lbs on a stock mani with no problems. and not having a return setup is nothing to worry about until you start to get up into the 250 ish hp range.

my D17 does not have a plastic manifold, what are you referring to ? Got some pictures of the turbo i bought for $75



one thing that kind of worried me is on the last picture, if you closely look right by the wastegate port you can see a crack going about 3 inchs long, does NOT go all the way through and i do not think would cause a problem. What are your opinions? My buddies dad knows how to braze maybe this would be a good idea ?

-Looking at the turbo blade does it look like all pieces are individually balanced ? if so could i buy a rebuild kit and do it myself ?

 

after doing some more research it appears that that cracking happens to other people on the same model of turbo as on guy says, "Good turbos, mod. mine on the 323 GT. Had it for years with no problems. but they crack the turbine housing a bit." I figure as long as its running so low of boost will never heat up to a point that it would crack even more, run my Mobil 1 5w-20 through it and water-cooled. The previous owner was running about 15+ PSI on this turbo so that could be the culprit.

 

I wanna see pics of this non-plastic d17 intake manifold. As far as I'm aware, every 7th gen worldwide uses the same intake mani, even the ones that dont have the d17a1/2. If you or someone else hasn't changed it, the intake manifold is made of abs plastic. And even if you aren't running high levels of boost, that snail is gonna get pretty dam hot. Maybe not as hot as it could, but that sucker will still be hot. Honestly at this point, my recommendation would be to try and yourself a new(er) t25. That turbo looks like its been beat death and left out to dry. And by the time you rebuild it, you could probably find a decent t25.

 

guess im kidding, it is plastic. For some reason i could of sworn it was not.

 

check out chimera's write up on swapping to a D16Y8 manifold in the DIY section. I would do that while you're doing your turbo.

 

nothing ever good can come from the statement "there was a guy..."

 

i know i know....but im just trying to say that it looks like it does happen. I do not think that i will mess around with swapping intake manifolds, its not like im turning it into a drag car.

-On another note, is there a way i could make an adapter for this turbo to an exhaust manifold, i am friends with extremely great welders. Maybe use some 7/16 thick plate for the flange, maybe a little thinner.

 

found some more people online that have the same cracking, looks as if it is not an unheard occurrence in these types of turbos and nobody cares to fix it.
