Help, I need downpipe advice!!!!!
 

Well, my car is in storage so the other day I took the top portion of the factory manifold off so I could bolt the turbo and manifold on. But there's a problem, the turbo only fits one way, without hitting the rad fan shroud, and it only fits without the t3 internal wastegate housing. I wanted to run the internal wastegate to save a few bucks, but now it looks like I have to run an external because this manifold only gives me so much room.

I was wondering if I have enough room here to safely use a t3 5 bolt flange (for external wastegates) and run a 2.5" downpipe off it without the downpipe being too close to the rad fan shroud and melt it (and yes, I know that I need to rotate both housings, I haven't got around to that yet) ;):

Here's the room I have to work with for a downpipe:

Here it is, with the internal wastegate housing.. as you can tell, it's not gonna fit:

What do you guys think?

Buy a new flange, some mandrel bends, break out the welder and make that ---- work.

Do you think I have enough room? I don't want the downpipe to be too close to the plastic raf fan shroud, I'm scared it'll melt it on a hot day.

I also have a bad oil leak, but the oil never drips on the ground. The motor doesn't burn any oil, but as you can tell it's comming from somewhere because it's all over the tranny.

Looks like that manni has the turbo flange tooooo far to the left.Looks like the tranny is also in the way.Thats your real problem.Did you make that mani?

Re:Help, I need downpipe advice!!!!!
 

Todd on here made the manifold. I guess it was ment to be used with AC, that's why the flange is so far over.

The tranny isn't in the way, if you're judging by the 3rd pic, that's just the wastegate housing laying on top to demostates how there isn't room for it.

I think with a block off flange (to run a external wastegate) I should be able to do some fancy welding and get the downpipe to fit, i'm just worried about it being to close to the plastic on the rad.

I had a similar setup with a 2 1/4" down pipe and it cleared between the shroud fairly easily and my pipes were not bent very well. It was very close to the nipple on the clutch slave though. I never had a problem with it. If you can get a good bend right after the turbo you can avoid all of this. Just cut the mandrel directly in half and use the end with the extreme bend on the turbo side. No problem. 8)

Cool, post some pics. :)

Stan

Re:Help, I need downpipe advice!!!!!
 

These are the only good pics I could find of it on my computer. In the second pic you can see how I had to cut the lower motor mount a bit to fit the acuator. You can also see in the first pic how shitty the bend was. If I would have used a mandrel and just welded it to the flange without the damn collector fitting I used I would have been fine.

Yours looks pretty close to the rad, so I guess I should be safe.

I'm thinking about getting a 2.5" mandrel U bend and cutting it and welding it to the flage so it basically comes right off the turbo 90 degrees and goes straight down.

Stan

Re:Help, I need downpipe advice!!!!!
 

stan i have a t3 flange welded onto a 2.5 piping that goes straight down-i made it myself if you are interested will sell it to you-got to wait till tommorrow to send picts

Re:Help, I need downpipe advice!!!!!
 

I think that would work out perfect.

If you look in the first pic you can see that it actually burnt the shroud a bit. The radiator came loose a few times due to my missing radiator support. :o

Re:Help, I need downpipe advice!!!!!
 

have you thought about putting the exhaust side pointing towards the drivers side? Anyway, buy a 5 bolt flange from someone that blocks off the WG and get some tight mendrel bends...it should work.

BTW that O2 housing sucks....i had to get a .42/.48 one to keep my internal gate.

Re:Help, I need downpipe advice!!!!!
 

I can't point the turbine housing towards the drivers side because the compress housing hit the fan shrowd too.

Okay, today was productive, here's what I came up with:

I went to Parts for Trucks today and bought some mandrel bent pipes. They had exactly what I was trying to describe. 3 pipes came to $55 canadian (~$39us).

The pipes:

1 45 degree joined to the 90 degree, to check for clearence between the turbo and rad fan.. looks good, lots of room!:
http://users.eastlink.ca/~sly1/IM001796.JPG

I'm gonna have to cut the pipes and shorten them a bit, and add the 3rd 45 degree pipe to get the end to line up with the cat. converter and add a 2.5" flex pipe. Here are the pipes lined up to approximatly where they have to be cut and welded:

Here's a picture of my friend's turbo gsr civic, he hasn't had any problems with his downpipe melting the rad fan shrowd, so I guess I won't have a problem either, since I have more space between my downpipe and the shrowd than his setup:

I think this downpipe will work out great. :)
What do you guys think?

Stan

Re:Help, I need downpipe advice!!!!!
 

That looks good Stan.After your done ...make me one :P

Re:Help, I need downpipe advice!!!!!
 

Hell yeah, that looks good. 8)

you do know that your oil return is at the top of the turbo don't ya?


Apart from that it all looks sweet.

Re:Help, I need downpipe advice!!!!!
 

Thanks guys, I'll post pics when I get around to welding up the downpipe.



Yes, I know, in my first post, I said "I know the turbine and compressor housings need to be rotated." ;)

Re:Help, I need downpipe advice!!!!!
 

So to keep a/c the compressor has to be facing the drivers side?

Re:Help, I need downpipe advice!!!!!
 

It's usually compressor on the passenger side.

Re:Help, I need downpipe advice!!!!!
 

usually to keep the ac it needs to be on the passenger side, but sometimes it's not possible.

stan, you might want to think about a slimmer rad fan, that DP will be VERY hot and the rad fanshroud is plastic and very close to it.

Re:Help, I need downpipe advice!!!!!
 

More money that I wasn't looking to spend. MY friend's downpipe is almost touching his fan shrowd, doesn't seem to be hurting anything. If it melts, i'll get a new fan. ;)
