O2 Mounted WG on a 2g, Pics?

[daren_p]

Was looking to see some pics of O2 mounted external WG's on 2g's and who's O2 housing you are running. I'm trying to figure out clearances with a Koyo rad & fans, thanks.

Daren, perhaps this link will give you some guidance?:

Daren,

I'm sure you already know this, but by running the wastegate after the turbo on the O2 you may have creep issues (please note the fact that I said "may" and not "will"). For proven rock solid boost, you can't go wrong with a manifold mounted external. Eiher way, it's 10 lbs. of crap in a 5 lb. bag.

Just my .02,

Andy

I have an RNR racing O2 eleminator 3" Turbo back With a Tial 38mm WG. The Rad is stock and I don't have any room for a fan were the A/C fan was.

 

[daren_p]

Ya that RNR housing is close, I'm wondering why companies don't try to put the WG on more of an upper angle to help with rad/fan clearance? (maybe contacting manifold is an issue?). What about some pics from different manufacturers, think theres usually slight difference in them. I went through the galleries but there werent all that many 2g's and the manufacturer's weren't listed.

Andy, ya I already know that it may not prevent boost creep. If I do go this route I will be properly porting the enterance above the WG hole & enlarging the WG hole to prevent creep. I think the O2 mounted keeps it abit more "sleeper" but I think the mani mounted route would probably be better as far as rad/fan clearance goes. My only issue is I need to run the WG recirculated back into the exhaust. I wonder if anyone has a setup like this, I guess this would be something that I would have to get fabbed up at my local custom exhaust shop.

Is there a certain setup you would recommend for this? What manifold and dump I mean.

A 2g manifold or a evo manifold is a great cost effective manifold and has stood its test in time. Send it out to a vendor and have them drill a hole and weld on the wastegate flange and your all set. Or you could pick up a new style SBR manifold that is already cast with a flange for a tial 38mm wastegate.

The 38mm tial is also a great wastegate that has stood its test in time. To me, the tial 38 is like the little engine that could. It takes whatever you can throw at it, then laughs at you and begs for more.

Sounds good. I was actually just browsing the SBR website and was looking at their manifold and tial package too, .

Reference post 48 for my setup. It works great and is much quieter than a dumped external.

Thanks Andy, that may be just what Im looking for. Looks like off the mani I will have enough room for the Koyo and maybe even the stock AC fan? (if not I can always get a Spal for that side) From what I've seen it looks like I wouldn't have any clearance issues with one of the PTE bolt on turbos with the E comp cover (5031RLE, 3431RLE) & still running the stock main fan. How long have you run your setup & have you had any issues with cracking? (wouldn't think so as it should be a solid assebly) I wouldn't think your reroute would disrupt the exhaust flow any worse then an external WG O2 housing as they usually dump basically 90 deg back into the O2 housing & this happens maybe 6"s away from the turbine wheel.

I guess there is always another route, I could tell myself the only way to get around this is to get the FP3052 with the recirculated O2 housing they have a pic of on their site

You mean this one ? It's not on their product list and never been able to have them build one, unfortunately. This is as good as it gets, however!

A koyo and a slimline fit here. Its a custom turbo-trix o2 housing and a tial 40.

Another alternative:
Here's an old shot of my 122performance recirculated O2 housing. I have an HKS 40mm gate that Andy mounted onto one of his housings. He's a great guy with great knowledge and prompt customer service

Admit it, you really want that 3052 don't you?

Mine has held up very well considering it's aluminized and press bent. There's really no exhaust flow disruption since it comes in at a fairly straight angle to the flow. The only time I had to bring it back for a leak was after the timing work to advance the intake cam since I needed to bend it out of the way to get to some of the PS bolts. I haven't flanged mine, but you could do that and remove it entirely on the top half if you needed to. I think you could even fit a slimline A/C in there and be OK.

A question that has been wandering around in my mind - are there (theoretically or otherwise) any ill effects of having a mid-pipe (aka a pipe extension of sorts) between the WG and the mounting spot? Obviously, there should be no abrupt turns or directional changes, but I can't think of any reason why this would be an issue.

I just found a photo in one of the Wisemen's galleries, but I can't seem to remember his profile name for the life of me. Perhaps someone could help me out (one of this photos shows this small extension between his WG and the manifold mount). I tried searching the gallery for "external" and "gate" but did not come up with the one I wanted.

It would depend on the length because obviously the reaction time for it to open would be minute, but still enough to not open fast enough.
A lot of companies use a "mid pipe" off the mani and they havent really complained about it so...

What companies have you seen offer these types of pieces? Off-hand, I don't recall any of the mainstream vendors carrying such pipes (or at least, none that I have seen).

 

[94Jettameowpsst]

Well maybe im not judging how long of a midpipe you're talking about. http://slowboyracing.com/more.php?id=3546&
OBX has the midpipe
AMS's 4294 manifold as well as most other large frame turbo manis have the wg about 6+inches away from the manifold.

Maybe thats not what you meant then

Yeah, I was thinking more along the lines of SBR's Lancer Evo III manifold. I think I'm worried about hood clearance with an external 'gate - just a simple 2-to-6 inch pipe extension would do just fine. If worst comes to worst I can always have a trusted local shop fabricate one up for me.

Pics of punishment recirc tial 38 installed on my car. Slimline fan definately needed, maybe 2 inch clearance to the radiator.
