If you weld that housing and in the event a piece sluffs off while running, expect some noise. Best to keep looking for a good housing..call some turbo shops and see if they can order or have on the shelf in some dusty old back room a new one. Those were on a good amount of cars here. Otherwise try a VJ20 turbine, much less likely to be cracked. You will need to fiddle with the mounting flange but it uses the same elbow pattern from the VJ14. The VJ20 will afford you a better spool up than the VJ11 anyway.

According to the original post, I could take my vj11, and just throw the V-J 14 hot side on to it? Hell, if that works, I don't have to play with a cracked housing.

Note that my setup is, from turbine to compressor, vj11 turbine and chra, tbird comp housing, ht12 wheel. Can I just unbolt the vj11 turbine housing and bolt on the vj14 turbine housing?

yes you can but that tbird needs more turbine housing than the R12 from the VJ14 can give. No real sense in that. Look for a vj20 housing and fiddle with the flange to fit the B6t manifold and then you will be better off..or look for a good vj11.

My turbo guy couldn't find one, or so he says. Anyone have a good turbine housing for sale?

Gaz why not run a different turbo then the IHI stuff.  For less then 800$ you can get a turbo, dump, and manifold that flows quicker and more air then the IHI stuff can.

Wouldn't fit the stock ish budget mod mentality I'm rocking for now. I'll probably be selling this car when it's done, anyway.

Just for giggles, can you entice me with a link on a recommendation?

The Garret GT2560 is a ball-bearing turbo that came on the Nissan 240sx and Silvia, this means alot of people sell them for cheap when they upgrade. If youre lucky you can get one for 350$, the rebuild kit is 120$ of ebay. You can get good quality aluminium t3 manifolds of the Mazda 323 GTX Facebook group for around 250$, you could reuse the stock blow off, or upgrade to a electronic system.  GFB makes a good boost controller you can get for around 150 used or 250 new. For the dump pipe Id have a turbo shop make it for me I wouldn't expect it to be over 280$.
If you got a non electric blow off you could save alot more, but as it stand it would be 1150$ for just the Turbo, dump, and boost controller. You'd still need the fittings for the oil drain,piping and a larger intercooler. That turbo however can give you up to 300hp on a good tune.  You could probably get everything for alot cheaper if you were good at scavenging things from the junkyard, and searching ebay really hard. In the coming months ill be starting my turbo build. I plan on detailing everything on my build thread.

Ssounds like you've got your turbo build pretty much figured out WashiestSnake.
If you're going for 300hp, you should also get some 500+cc  fuel injectors and a new ecu to control em.

Yea everythings planned for the only problem is im stuck with the shitty F-series, my cars a N/A. I cant seem to find a Escort GT either to scavenge the transmission from I might end up having to get one of ebay or just run real low boost until I can get the GTX stuff put in.

Another problem I have is that ill be moving soon, and going back into School in May so that may mean ill have to hold off for longer. Im honestly thinking about just keeping my b6 and turboing that, BPs are rare as hell down here. That would help me save alot of time on the AWD swap aswell, as im horrible with wiring thats the main reason I was planning on using the Evo ecu.

I'm incredibly interested on the evo ecu bit. What's that about?

Basically its a reflashed Evo8 ecu meant to run a BP. It includes a wiring harness, and depending on if you buy it or not you can get a C.O.P kit to go along with it. Its made by BP Performace on Facebook and a few GTX guys on ClubProtege have switched over. It requires a Map sensor and a Cas sensor from a Miata. Ive talked to him about using it for a b6 and he said it was possible but not very easy. He said he had a hard time getting a b6 Miata to run right. Basically its way cheaper then Megasquirt and you get the ability to download tunes straight through a connector on the ecu rather then having to use a laptop like Megasquirt. It also should have much more reliabilty.

My plan is to buy a BPT, get it installed then install his Ecu setup. I eventually might get a BP4W head aswell because he takes Evo manifolds and reflanges them for BPs so that would take allof the hardwork out of using the BP4W. Also it uses stock connectors so you could always install a PnP MS3 to run the vvt.
