To the person who has it installed, did you get a donut gasket with your o2 housing? I tried to source one at local part stores with no luck, then wasted $20 ordering one online that doesn't work either. Fp said a couple weeks ago they now have some they'll be sending to customers who ordered the cast o2.. I'm still waiting.

And e kobz I bought a ss jb black as well. Granted I'm stock block with mivec. I just wanted room to grow when I build a 2.4. 4200rpm on a 2.3 is fine by me lol. Honestly if this turbo hits full boost by 5200rpm on a 2.0 liter I'll be happy. I'm used to a hta86 on my evo 8 lol.

I'll try to get a pic of mine when I pull it back apart from test fitting. It does feel super heavy but it's definitely not 16 lbs. I weighed it because I was surprised at how heavy it felt and I think it was around 7 lbs. There's some room for porting but you won't be able to go a full 3".

Also to the person stating the stock mhi turbos are on their website, yss they are but for a very steep price of $2500. With the sale they have going right now one could pick up a green red or black, lines, gaskets, and the cast o2 housing for under $1500 and all you would need is a wg and fab a dump. I would much rather do that now that they have made a piece to retain my existing down pipe and still utilize the better flowing ss housings.

[QUOTE=awdordie;11555168]I take it that the inside diameter is not a true 3" piece? Wondering because on the website it says that it is.
That's the impression I had also but no it isnt. It has an outside diameter of 3" on the exit but due to the thickness of the cast, I'd say it has an inside diameter of 2 5/8" - 2 3/4". Most of the aftermarket mhi o2 housings (w/ external dump) had a 2.5" outlet and didn't seem to be a restriction for the fp mhi turbos, so I suppose it'll be sufficient for my ss housing green.

The journal bearing mhi turbos on the FP website are $1599. In the holiday sales tab. Bottom left. The ball bearing is right next to it at $2599. $1599 I thought was a steal. And yes, the ss housing flows better due to more recent design, but I thought it had been established that mhi will spool faster since it is twin scroll? Correct me if I am wrong. I only own the mhi.

I ordered one of the o2 housings even though i planned to just fab something, it would have cost almost half in material plus time, and ive been busy lately.
if i had known how heavy it is, i wouldn't have bought it, i would have just made something.
unfortunately i already have it so im just gonna use it for the time being. it looks like theres room to port it but im not going to bother, at that point id rather build something from scratch.
on the plus side, i emailed about it and they claim theres nothing lost using this housing over a 3" full downpipe.

Those are awesome numbers on a mustang dyno. I specifically wanted this turbo to be a little lazy to save my stock block and to make 500 + looks like it'll do exactly what I want. Ah Im excited to put this turd on now. And yeah an FP zero is sick but just out of my price range. As cheap as the black was on the holiday sale it really was a "**** it why not" type of purchase. I mean seriously the whole package was almost the same amount as a tomei 20 G. (Im a cheap *** and just bought a knock off wastegate however)
