can a ramhorn mani be adapted?

[boostwut]

I'm looking for a manifold that has external waste gate to use for my hx35 build. now i have the BEP .55 housing for it to make it a mitsubishi. bolt on but this manifold i found is a t3 style. now my question is if i use an adapter like the one listed below will it put the turbo to far down? OR can i take that flange off and have a Mitsubishi style flange welded on with out any issues?

mani:
90-99 DSM 4G63 T3 RAM HORN EXHAUST MANIFOLD HEADER 1G 2G | eBay

adapter:
T3 Turbo Inlet Manifold Stainless Steel SUS 304 Adapter To 16G Big Turbo | eBay

thank you.

You could use an adapter, but I don't think they're the best option. If your housing is Mitsu flanged, why not go with a FP manifold and external wastegate off the O2 housing? Or see if you could trade your housing for a T3 flanged housing.

I agree with 1990AWD, with the BEP housing you would be better off with just going with an FP mani and wastegate off the o2. Plus going that route would probably save you around 400 dollars! Unless you are going for just the looks of the ramhorn manifold then go with the adaptor.. But Im telling you you will probably choke the hell out of that holset even more then the BEP housing originally does. just sayin..

I would just get a t3 housing for the turbo if you can.

From personal experience, and adapter can be used. Get some ultra copper exhaust sealant and you should be golden...or at least copper.

T3 or a bep would be a great option.

I have a 1/2" adapter that I was going to use to do the same thing but ended up going a different route. PM if you are interested in it, its brand new. If you just shorten your downpipe a little where it connects to the o2 housing you should be fine for clearance

I'm sorry but i don't get what your trying to say i already have a BEP housing the question is if i can use an adapter to a t3 mani and make it work.

well i wouldn't mind trading my bolt on for a BEP t3 housing for my holset but since I'm a newbie i cant post yet and i don't know where else to post.

but originally the reason i went with the .55 bolt on is to increase spool rate at an earlier time. and i don't really see how the adapter would choke it that much, wouldn't some port work and polishing on the adapter and collector flange help out?

so I'm assuming that i can't just re weld a bolt on flange onto the mani then?

also another thing is my holset came with the original hot side that is divided if i knife edge it can i use that housing with this turbo? ( as in strait bolt on)

As long as there is no abrupt (sharp) transition in the adaptor, it wont impede flow. However, I would be concerned that lowering the turbo could create interference problems.

so I'm assuming that i can't just re weld a bolt on flange onto the mani then?

Theoretically possible; but the collector will most likely not line up with the flange, creating a flow restriction.

No; the bolt spacing is all wrong to do that.

My suggestion: you have the BEP housing already. So if you need a new mani, buy a DSM flanged tubular if you want that or a FP cast manifold.

just making sure i got you right. so i can't use a t3 manifold (like that ram horn) on the divided housing?

I agree with Kevin. Once you gain Classifieds access, you can sell that BEP housing for more than the T3 housing would cost.

Also, that manifold in the ebay link is not custom at all. It's an OBX manifold. I used to own one about 6 years ago. They sell for $350 brand new. Here's a thread about it: http://www.dsmtuners.com/forums/bol...al-length-ss-tubular-manifold-looks-good.html

thanx for the input. yeah i know thats not a custom part ive seen it in the obx site and other sites before. but i was just using that as a reference point. how much do the the t3 housing go for used? and they are also made by BEP right?...

It really bugs me when eBay sellers misrepresent their product. I'm glad you knew it wasn't "custom".

You'll have to poke around the Classifieds section to find the going rate for the T3 housings. They're a dime-a-dozen though, so they shouldn't cost much. And that BEP housing is in demand right now. The T3 housings are factory Holset houisngs.

I misunderstood you/got turned around in my head. A T3 housing will fit a T3 manifold.

o ok gotcha gotcha my holset actually came with the factory hot side and a v band outlet attachment ill post pics on profile as soon as i can. cause ive herd of people that knife edge it at the divider to not have to use divided manifolds. just wanted to see if that was true... and thank you for the look out, ive been following you work with our cars for a while.

no problem and thank you for the info

I remember back in the day, Jake Hanhardt tested exactly that. He used a regular T4 manifold and ran it with a open turbine housing and then with a divided turbine housing. They performed the same so there was no downside to a divided housing on a non-divided header.

Also, the housing on my 60-1 was divided and it was fed with a regular 3" pipe. It spooled just the same as it did when I ran it with a divided T4 manifold. And my new set-up will be similar; divided housing on my Holset without a divided feed. I didn't knife edge the divided last time, but I plan to try it this time around (even though I don't think it will make much of a difference).

 

[boostwut]

so the stock holset hot side housing works with a t3 mani then? just want to make sure.

the reason i went bolt on housing (bep .55) is because i herd its the quickest spooling option. im not looking to max the turbo out at least not yet i was assured i can make 400 hp with the bolt on. is this true? now i know the stock housing will push the turbo to its full potential but at a cost of a later spool time. this is a street car not a drag car so drive-ability is important to me.

i just want to make sure im getting my facts right.

Yes, a stock HX35 exhaust housing is setup for a divided T3 manifold. You can use an open T3 manifold if you want though.

The BEP will not spool the fastest. The stock exhaust housing with a twin scroll (divided) T3 housing will. I'm not sure where the open T3 manifold fits with the rest of the options.

Yes, you can make 400hp with the BEP housing and DSM-flanged manifold.
