so ...no time for this
so far so good, still have not chance to go to dyno but I'm at 18 psi now...!!!
1st and 2nd gears are a joke (spinning)! and the turbo lag is neglible ... very close to the old twins...

It's probably the shitty E-Bay turbo LOL!
Good Luck...........Let's us know when you get it completed!

But to give you all a REAL FEEDBACK, My car has currently one installed (about six months from now) 300 rwhp @ 10psi... 3rd Gen 94 FD ,,, I'm a HEAVY FOOTER!
HKS Style Manifold
T70 Turbo
50mm HKS Style WG
The Turbo is installed with a "tangential" T3-T4 adapter to fit the manifold inlet.
The manifold and wastegate are fine, no cracks no stucks so far... The Turbo pulls like a MF! at 10 psi with virtually no lag ... I hit full boost at 3500 rpm, however, I went to dyno last Sat to hit serious hp (20 psi) and the turbo oil seals went out trying to get 15 psi ...
Finally, I'm very happy on the way the turbo perform, but if is not going to last it may be better to go another way. Actually, the turbo was the first ones they sold "Master Power". Now they are selling XS Power. I read the Master Power were the same XS turbos but that they were just using the MP housings...(I don't know)
Anyways, I have another XS Turbo here so I'll try it. I will install it today and dyno on thursday
hopefully my feed back will help to clear this out,,, I will keep you informed...

My fellow Puertorican friend was just bragging to me about his new dyno numbers last night. "458whp" with his holley carb setup. The funny thing is, he kept saying how much that new turbo spools. Master Power T70. There is a local shop that sells the turbo alone here for $625.

can't speak for the manifold but we've put one ot the early T70's offerings from masterpower on a PT GT of all things to great effect.. it's NOT a 'T70' by garretts definition bt i don't have exact measures of impellers to knwo which it is comparable to..
the 35mm waste gate is built by Tial for them.. I'm a reseller of tial and Iv'e seen enough of the older 35mm to know one.. everything offered down to the 10mm banjo fittings and the spring wasers is Tial.. "is it actually cast using the same grade of materials as the Tial " ,is another question..
the 50mm is a joke. from the casting alone it shows an overabundance of flash inside and out, the alloy used TIG welds like low end 1100 ( not pits that i've found ) the base is more then happy to conduct heat into head and I don't think the diaphram is made with or contains a high level of nomex letting it get soft. Just some of the things I've noticed about the parts. without taking a micrometer to the parts like some of the guys..
I would think that a heat isolator between upper and lower assemblies, a complete re specing of the parts and even a HKS replacement diaphram would do a world of good for this item

I've purchased an OBX manifold for the FD and a SS autochrome manifold for the MKIV. Never got to put on the OBX as I ended up purchasing another FD with a blown motor and a full TD06-25G kit.
Only observable problem on the OBX was a flange that's not flat and that goes for the SS autochrome manifold. Both needed machining to get them flat to fit. The Supra manifold from SS autochrome has very high quality welds and hold up well after 6 months running 20psi boost. The "crappy" 50mm HKS style wastegate works like a charm though what I hear is it gets a whole lot hotter on the RX7 due to the closer proximity of the wastegate to the housings and higher under hood temperature and may be the cause for higher incidence of failure on the 7.
I've seen truly horrible manifolds so I know how the SS autochrome manfolds comared with the poorly made items. Previous to these two purchases, I had a bad experience purchasing from another now out of business eBay vendor and the Supra manifold they sold was a true piece of crap with flashes inside the runners and staggered joints. They refused to refund but luckily for me, the manifold was fully insured when I returned the manifold to them which somehow managed to get lost in transit and I got my money back through the insurance company.

second report on this stuff (kinda long)
OK, another friend got suckered in. He bought one of the SS Autochrome T3/T4 t04e turbos, with the manifold made to fit a honda.
Quick report on a visual this time as he has already decided that I will be installing it (how the f*&k he decided this is beyond me though) the manifold uses a very low grade stainless can't give an exact on it though, but it seems that after I warned him about it he called the guy before paying and they claimed to have fixed the problems. they have retigged the entire manifold to hide the previous welds, and it looked like it might hold together but for how long is anybody's guess. the inner runners had been ground but not very well. lots of flash and the wastegate flange and pipe was like about 35 mm or so. that was aimed about 120 degrees oposite of the exhaust gasses path.
the flanges themselves are flame cut mild steel that has been rough ground, and then it looks like before they welded it they might have chrome plated with a very thin chrome dip
Dana won't let me do any of my normal testing measures (slightly destructive
) to find out what its all composed of (I promised to retig it when i am done but he said no dice)
the turbo itself looks like this
compressor wheel is a standard T04 design but its very rough with flash around the edges of the inducer and exducer fins, looks almost like a shitty casting.
center housing looks just like a Garret TO4E I have sitting under my table, same with the backplate. Dana won't let me dissasemble to look at bearings and the like (I will check them when it dissasembles itself)
the exhaust housing has what upon a quick glance looks like the Turbonetics "T" but it is really a cheap copy of that trademarked "T" that has been slightly modified so look similiar to it but not exactly, the casting is very porus , and it looks to me like it was cast to cold common cause of porosity in cast iron and cast steel with what was obviously a couple of colder spots in the casting
and here's the winner:
the compressor housing itself has been welded around its circumference, and then reground (very shitty) with obvious undercutting on the weld in an area they couldn't reach with a grinder (by the outlet side between the snail and the outlet itself), and then repainted with waht looks like a high temp paint to cover the surgery.
I will post photos tommorrow if i can get Him to let me take photos of it (I think he realizes that I heavily dissaprove of installing garbage) , and I told him that he's on his own with the actual reburning of the Eprom, as I am not taking it to any of my normal haunts for the computer (I am mortified of the idea of having it fly apart while they are working on it) I must say that this things QC looks worse then the wastegate that one of my nissan buddies tried.
but, and I say this with complete sincereity its all good, cause its going on a honda
sorry for the long post
