Got a TB0384 being delivered next week - usual hairline cracks around the wastegate hole but that's it. It'll be getting a rebuild (when money subsides) at Universal Turbos just a few miles from me.

That T34 ended up going for £271 in the end, I bought the 4x4 T3 for £150 delivered.

Still not arrived this T3.... Is everyone using -3AN or -4AN for the oil feed? Think I might adapt the stock Volvo 13C hard line if it all lines up probably, hopefully, or have an AN fitting TIG'd onto the end then run a braided line from that. Don't fancy a braided line under all those hot exhaust bits.

I've used a 1/8 or 1/4NPT male to -6 AN male/male fitting in a little plate bolted down..I've cleaned up old Saab 900 and 9000 oil inlets when they were common as chips in the yars, then make a pile of 'em on water jet--Like $5 each so better-er-er than stumbling around in wrecking yards..
Like this--usually in steel


I feed the turbo from a remote filter head in line on the way back from the oil cooler--my thinking is the poor little turbo is the hottest thing, and maybe it be happier if I feed it nice cool oil right back from the cooler rather than picking oil up in the sump and feeding the poor widdle thing oil that is who knows but maybe 120C.

Maybe you can see the thing --this is my old Frod Crossways Frewbie Frew

Does the T3 not need a restrictor, or? Was tempted by this;

http://www.atpturbo.com/mm5/merchant...egory_Code=BCS

But I see you can get products like this;

http://www.alibaba.com/product-detai...087488168.html

Which is what you describe. I wont be going remote filter myself unfortunately but the oil will have a water-oil cooler with a bigger rad. Also helps in the colder climate of the UK to warm the oil up on start up.. Of course wont be using Alibaba products but UK ones. I see plenty 4AN oil feed flanges but not 6AN.





That and that, I think.

I've got M10 studs but I think I'll have to get these drilled out.

Yeah that's a 2wd housing..I pull the studs drill 'em to clean--like 10,2mm I'd like to do a little spot face on the 2wd units where the nut will be nestling vause its 'as cast" now and the face is thinck enough we could kiss it and have more room for the nut--I us reduced hex 15mm AF..

lil' crack ain't nuthin.

Wasn't aware it was a 2wd housing but it has TB0384 stamped on the front, I'll measure the comp wheel just to check.

Is it worth having the studs drilled out to 10mm/10.2mm and remove all the threads? I have M10 studs and nuts with me.

Nuts I have are usual VW/generic copper flashed nuts M10, not reduced hex, can't remember but I like the idea of spot facing.

I can use a Volvo T3 CHRA in place of the Ford one, can't I? Just swap the wheels over and balance. Means I can get a cheaper refurb and use the stock T3 Volvo hard oil feed line.

Wonder if I can get a 360 bearing for it..

Got my TB0384 refurbed by Turbo Dynamics here in Christchurch. Fab company, albeit a pricey refurb but had a 360 bearing done, some comp house machining, some wastegate machining and a clean too. They also drilled out the turbine housing intake to M10 straight through holes.

Wastegate bracket? B21FT wasn't it, or just any 'universal' bracket?

Almost there. I'll stick some Permatex grey or Loctite hydraulic on the NPT thread only a small dab.

ever heard of cost/benefit analysis?

Ever heard of the idea of 'good enough'?

Is the Cossie T3 the bargain it once was, though? They're getting expensive now.

I bought mine and had it refurbed for £520 ish all in, may be pricey but compared to a Kinugawa 16G/K24 etc it isn't too bad. Cheaper than those ball bearing turbos.

I've found the straight actuator rod doesn't work with a B21FT wastegate actuator bracket. Is a Z bent actuator required?

It would be interesting to see a real back to back comparison between a Cosworth T3 and something new (not 15G etc). I can't and don't want to deny the advances in technology, it would be nice to see if it is 10% or 50% more better something something.

On mine I have a flat bracket that was OE Bentley, that was just a piece of plate with some holes punched out. No Volvo bracket (which was nicer quality with the profile and nicely rounded edges).

As I recall, I made a new bracket to line everything up.

Think the cosworth .48 (t4 50 trim cold side) would be the limiting factor to make power to 7500rpms on a 531 8v head with 38mm exhaust valves and a stage 2/3 RSI turbo cam?

Engine finally went in yesterday - but I found the wastegate bracket holes that I bought does not line up to the compressor bolt hole spacing. Was it a B21FT bracket that fitted perfectly, or? What did others do on the TB0361/84's for their wastegate actuators/brackets? I also have to buy a Z bend actuator as the straight Cosworth actuator I bought wont fit.

My f**king English is fine, but since I rarely understand El Layish lets make this abundantly clear.

I answered "No" meaning it would not be the limiting factor on that spec engine--

I clarified furhter that I know it will not be: "because it is not the limiting factor on an a YB(G) Ford engine that flows vastly more air and makes 30 psi boost and revs happily to 7500...and because I have one of those engines and have used them on other 8v 2300s

Have I elucidated the answer sufficiently? (Personally I wouldn't use the T4 cold size from the the description "T4" since there is a multitude of wheels with major diameters from 70mm to what? 78mm.. TO4Es and TO4B and all kinds of stuff. But its not clear what you have but don't worry the problems won't be in the turbine housing...

Yes, perfectly understood! Thanks John V! I did mention it was a 50 trim.
