Mountune Fiesta MRX Turbo

[Chops]

So let's say you have an ATP 2554. What are the chances of sending it into Mountune to get it upgraded to the MRX turbo???

Just a guess but I'd say slim to none. You'd probably be better off selling it and buying the MRX.

I paid $10k for my LS3 stroker...lol

BUILT Mast Motorsports (as opposed to one of their crate engines), or local custom builder?

I think the exchange rate has changed since the dollar has strengthened.

Or the pound being severely devalued due to their 'genius' Brexit. LOL

My engine was built by Dave White at Redline Motorsports (West). Engine dyno'd by CPR Engines. Custom built to my specs with their input. 637hp/586flbs 416ci LS3. She was a romper.

Yes, that one....lol

A ported stock manifold would be great on this setup.

Honestly, I want to take the turbo off and throw the ebay manifold on, but ive changed turbos 3 times and I'm freaking SICK of it... maybe ill wait a month xD

I would like to see that as well!

Call me snobby, but I would love to see that adapter go away. Something about having a vband turbine housing and not using it gets me.

The Pumaspeed V fits the 2800 series ATP. I emailed ATP and they did confirm their 2554R and GTX2860 uses different "turbo to manifold" and "turbine to downpipe" flanges. I got a beat around answer but they said the two kits do use "specific parts". Looking at Garrett's specs the two turbo frame sizes are slightly different which makes sense. This would indicate that positioning may be off. However, they have to be very close by looking at thd picturd of them side by side. The next move is to contact Pumaspeed to get some measurements on the difference between the stock flange and vband manifolds. If the centering is identical then the distance moved back can be compared to an MRX flange. It needs to be very close for the oil dump and downpipe alignment. But it just may work!

I may just order one and give it a shot. If it doesn't work, exchange for the stock flanged one.

That's very interesting you said that.....hehe.....someone just may have to test that idea and another idea at the same time.[emoji106]

Where are you guys getting your ported stock manifolds, Ebay then porting them? I have had a WTB posted for a few weeks now with no avail. Of course, this is before I was considering the SS options.

I definitely get the appeal of the stock manifold. Even if the stock shield won't directly fit the entire housing of the Garrett core, it could be modified to cover just the manifold, which will still help greatly. Heat is ALWAYS the enemy

Be tough to find now that skittle is out of the scene. Takes alot of time and bits to port one.

Actually heat is what makes your turbo spool. Hence the cast manifold being so nice. But I get what you're saying. Someone on here supposedly picked up a turbo blanket (saw in another thread) I'm interested to hear his opinions and results from that.

I'm not sure the compressor is any bigger on these than on a hybrid. The benefit I think is the exhaust wheel.

Yes, I meant radiant heat, not internal combustion heat within the manifold increasing velocity. A properly designed equal length manifold should outperform a log manifold in every way. Durability is the only catch. Too bad these weren't made to be twin-scroll with a twin-scroll turbine housing in the MRX turbo.

 

[thePete]

I am surprised with all the new offerings coming out that no one has made an effort at a twin-scroll set up. I've seen how much they can cut spool times on an equal sized turbo frame. Port matching and thermally coating an Ebay manifold sound like it might be a viable option. I don't see why you couldn't just get an appropriately sized v-band flange welded on to ditch the adapter too...

Honestly, me too. Twin scroll definitely cuts times substantially.

Ebay manifold definitely has its merits. Welding the vband flange is doable but it's about spacing. The flange would need to be fabricated on the car with the turbo to ensure the proper placement for oil drain and downpipe alignment. It would be great to find a bolt on solution.
