Default Question on a Manifold...Might belong in welding forum im not sure...

Ok well here is the deal...this isnt honda related but i want to get some opinions from you guys anyways...A friend of mine had a custom manifold made by another friend of mine and he posted some pics of it on another forum and people on there started talking **** as usuall, saying that the way the turbo is angled will put excesive load on the bearing and all this other ****, I told him he will be fine but he wants more opinions...here are some pics. Let me know what you guys think.






Oh and by the way thats a GT35R....and yes, its going on a NEON!!!

I'm intrigued to know what people say...and by people I mean the reputable people on H-T. Such as mase, earl, G-E, and all the other well known engine builders on here.

Basically I couldn't care less if joe schmo noob says yes it's bad-***, I want reliable people damnit! hahaha

angle is a bit extreme. youll start blwoing out seals real soon you can go up to 30 degrees but that seems a bit more

I talked to my buddy that mad the manifold and he said that the pictures makes the angle look alot worse than it actually is and that the turbo is actually only at a 10 degree angle and the feed and return are pretty much vertical.

It will be fine then...

It doesn't look too angled to me. As long as you position the oil inlet and drain as near verticle as possible it will be fine.

I'd bet that it's going to work fine.

In Maximum Boost it says that the oil passages should not be more than 30 degrees off verticle, it looks to be well within that to me.

Is your "buddy" on crack? If you want to run the chance of ruining the very expensive bearings on a GT35R, go ahead and run that manifold.

Straighter than it was, and straight enough to show that's definitely more than 10 degrees of angle to the turbo.

Like I said, if you want to run it and risk a very expensive rebuild being that this is a ball bearing turbo, go ahead.

i just straightened out the picture in photoshop, brought it into illustrator and figured out the angle to be ~20*...give or take a degree.

Well your line isnt straight either, making the angle seem worse. Took a protractor to the screen, estimating its something between 20-25deg, so its ok. Oh and that maximum boost book shows the longitudinal angle, not the lateral, this would be the lateral angle....

Ahhh...

You are right. Then I don't know, maybe it won't work....

In fact, now that I think about it. The turbine side of the turbo doesn't really have an oil seal in it, just the bearings and a piston ring type seal, which is not an oil seal.

Seeing as how the turbo is positioned with the turbine housing down, the oil might easily seep past the ring seal and into the downpipe causing smoke.

well if he can weld then he can shorten the runners and weld the collector back on straight. did you guys have space issues?

hey everyone, this is my car situation goign on here. yes we had very limited space..if you havent ever seen a dodge neon turbo setup, you have very limited space..and with a turbo this size it is difficult. here is a pic

Turbos are heavy in the long run manifold will suffer.

lol thats a little off topic man..we are talking about oil/bearing issues. i think this manifold is plenty strong, its thick and welded very good..very good materials.

I don't see why you can't chop it off and reweld (unless it's still just tack'd). I doubt putting the turbine angle ~10-20 degrees off the flow of the collector will do much. Even if you split the difference, you can't go wrong. Space-wise the move would just have the turbo use realestate currently occupied for the manifold.

I'd rather make a few less HP than chance loosing power over time while the bearing dies, or at worst, blow the whole works up. Inertia = mass x velocity (I think =P) - damage from a 150k rpm turbo explosion wouldn't be unlike a motor seizing at 8k.


And I can't see a neon motor costing more than a GT-series

Yea, I agree. There is too much angle there. Anyway you can re angle that flange?

youre right, the gt35r (while i dont have a great idea of what it costs) must cost more than a neon engine. i was just talking with a buddie who can put together the 2.4 Stratus engine with SRT-4 internals for under $500.

too much angle, your turbine seal will definitly go out soon, as well as your compressor side starve for oil.. that manifold has both lateral and longitudal angles

looks good though

already cut the flange off and positioned the turbo so it isnt at an angle.
