Anyone have pics of the turbine side of a boostdesigns.com turbo

[virus77]

I need a pic of the turbine side where their downpipe attaches to the turbo. I want to upgrade my manifold and downpipe but I want to see if the flange is the same. I currently have a garrett with an internal wastegate and a 5 bolt flange, just want to make sure before buying. Also will it cause any clearance problems to run a .63 turbine vs. the .48 that boostdesign made it for.

turbine side is the hot side

Robby isn't so smart...

[virus77]

almost, now some from the other side of the turbo where the downpipe attaches, thanks for trying though.

Its called old age!!DAH:)

LOL ok here I think this is what you are looking for.

Manifold has a built in external wastegate so you will have to get a external wastegate. Also the downpipe is a 5 bolt pattern.

[virus77]

I think it will actually workout, thanks for the pics. If not I'll chop the flange off and have my machine shop make me a flange.

EDIT: I hit over 400 post and got my bolt on turbo sweet.

[DammitBobby]

Hey for an extra 160 you can get it external!

[virus77]

Hey do you have a pic of where the downpipe ends under the car, jsut to get an idea of how I will connect it with my catback.

[DammitBobby]

No I dont have any of those but if the weather is good this weekend I will try to get a pic for you.

[Jookmasta]

hey what kind of coil is that?

you want a pic of the exhaust turbine or the compressor turbine. I assume you mean the exhaust side since you mentioned the downpipe, but you know what happens when you assume.

There are two types of 5-bolt flanges. Ford 5-bolt, which nearly (I think every) aftermarket turbo manufacturer uses, and Dodge/Mercedes 5-bolt.. which Boost Designs uses. They say it's done for clearance, to get the 3" downpipe to fit. It is. With the Ford 5-bolt, the 3" pipe needs 2.5->3"a transition (atpturbo.com). The transition takes up alot of room, so you need to cut the downpipe below the 90* bend, and rotate it. Weld in the transition to the ford 5-bolt, a 1/2" piece of pipe for an extension. Even then.. the bottom bolt on the flange will be a pain to get in. To do all this properly, you need a bandsaw and TIG welder, and the turbo/mani/downpipe off the car, so you can mock things easy and correctly. Using a cutoff wheel or mitre saw with metal blade will take alot of metal out in the kerf (sp?), and I don't think it will work. You'd need many more 1/4" to 1/2" pipe rings for extensions.Anyway.. I've done this. As you can probably tell. My advice, if you are going to use your own exhaust (i.e. you already have one), you will need a mid-pipe made between the downpipe and your exhaust. If you are doing that, have them build the whole downpipe/midpipe at once. It will be much cheaper and faster. If you can weld, have a buddy that can, or plan on running their exhaust (because it mates to their downpipe), then doing the "flange swap" will be cheaper.

Summary:It will take alot of time and money if you have the Ford 5-bolt flange, and wish to use that downpipe with the dodge 5-bolt flange. Unless using their exhaust, just build your own downpipe.-Jeff

I just saw a post asking where the downpipe terminates.It terminates about 1/2" to 1" left of beginning of the bellhousing.You mentioned hooking it up to your exhaust. Won't work without a custom midpipe. And then I'd suggest having whoever makes that, make everything.

I had a revhard manifold before, with a downpipe I built running to an sr20det downpipe (my midpipe), which bolts to the exhaust. To run this boost designs downpipe, I hacked my sr20det downpipe (midpipe) apart to run to the BD downpipe. If you know where the sr20det downpipe terminates, it needed to be 4-5" shorter, ~2" to the passenger side, and at a different angle. Rather than meeting about parallel to the ground, it meets at about a 45* angle with the ground.Again.. lots of fabrication.-Jeff

[virus77]

I can get a mid pipe made, thats why I was asking where it ends, as for the housing, I guess I need to look into it some more, Im sick of my log manifold and I want to upgrade.

Hey rseabrooke, you wouldnt happen to have a shot of the backside of the actual turbo would you.

[Jeff240sx]

Again. Unless you have a picture with a ruler showing you the bolt spacing, you can't tell the difference. It's the same bolt pattern.. but the Dodge 5-bolt holes are much farther apart. I think 2 of 5 bolts will bolt up when using the wrong flange.-Jeff

[virus77]

How bout I just weld it right on to my turbine side. with three of the said bolts on. Thanks for the heads up but there is always a way around it. Im sure ill figure something out or sell it in the classifieds section.

You intend to weld stainless to cast iron? The two* bolts that fit are the top two. The downpipe is sortof "S" shaped, which would make snaking it down into place with a turbo attached to in very, very hard. The next issue is that you have an internally gated turbo, and the downpipe does not have a port for the wastegate. And, the manifold and downpipe have a 90* angle missing, where an external gate is supposed to live. And by the looks of it (I'm not 100% on this), you can't just drill a hole in the flange for the internal gate exhaust. It looks like the 3" piping bisects where you'd drill.Again.. I'm not trying to **** on your ideas. I'm just preparing you for all outcomes. I had 5 weeks of downtime while fabricating the BD manifold and downpipe to work on my car with my exhaust and my turbo.-Jeff

[virus77]

Im changing to a external gate with the new manifold. your right about the cast manifold thing, damit. I think a new flange put on the downpipe would be easiest if it doesnt work.

[DammitBobby]

Yep welding a new flange on the downpipe would be the easier route if you need to. Going with the external wastegate is also a better route.

[virus77]

I guess I was unclear at first, my intensions are to swtich to external gate, new mani + downpipe and keep my turbo.

[Jeff240sx]

Last time I'll post in this thread.. I just really need to drive this point.It's not as easy as switching flanges. A 3" downpipe does not fit on a Ford 5-bolt flange (it overlaps bolt holes), which is why it requires the transition. Which then necessitates all the work I listed previously. Same with the exhaust, if you don't plan on running the Boost Designs exhaust.-Jeff

[virus77]

I see... How bout changing my turbine housing. Anyone know where to get one.

[DammitBobby]

I am missing the point here. I had a custom pipe connect from the downpipe to my cat back exhaust for under a 100 bucks and it was 3 inches. What is the big deal in changing flanges on the downpipe??

[virus77]

the flange that hooks the downpipe to the turbo.

No. You are missing something. You can't weld a flange for the same reasons I listed. You need the 2.5" to 3" transition, but that would throw the downpipe out of line with the wastegate dump, so you need to do alot of work to it to fit correctly.Anyone can go to Midas, spend $50 and have them MIG the pipes together. Just expect to go through $200 worth of piping ever 2-3 years (I know from first hand experience.. my first downpipe was Midas-migged) because the welds will rust out. It needs to be TIG welded with stainless filler.And.. your midpipe for $100 is what needs to be done to hook to the exhaust. I hacked up my Trust sr20det downpipe to fit. But again, TIG welded stainless piping is more than $100 without a hookup. And if you got one, you have no business comparing your price to someone elses.Finally.. Midas, other exhaust chains won't touch a car without a cat.. which is any s14 with turbo.-Jeff

I'm curious how klattr1 set his stuff up when he switched to the BD mani...this news is kinda discouraging because I don't really want to get a BD turbo, but the mani/DP combo looked pretty appealing.
