Hi all,

Sticking this out here, I'm planning on doing the usual turbo swap to my RHD 240 soon, it'll still be a daily driver for sure however, so not looking for massive horses.

Being in the UK there's an abundance of Cossie bits and bobs about, especially regarding T3 turbos. I've trawled through the threads on here, seems everyone is going for a .48 hotside with a 52/60 compressor. I aimed to go for 15G, but with the options available over here regarding the Ford scene, and upgrade options for T3, I've decided to stick with the latter.

Here's what I'm aiming for so far;

B230FK/FT with;

Most likely brown top or VXR injectors.
012 MAF with the 3" throttle body, modified K-jet manifold for EFI. Being fabricated up soon, just need to TIG the intake flange on.
Either V or A cam
Adjustable pulley
3" exhaust.
Ebay or AutoSiliconeHoses intercooler - the latter fits right in the front with no problems.
It'll have the 5 speed manual M90 gearbox bolted to it as well.. So none of this auto nonsense.

Seeing as it's a daily driver, I wont be requiring much of the top end, as in upwards of 5/6000rpm, so some good low to mid-range/low top end would be ideal. I've heard a few bits about this elusive '50 trim' T3 that's about... But school me more if needed. Will the .48 turbine with say a 52/60 compressor side aid this setup, or am I talking bollocks? What would you recommend?

All advice taken on the chin...!

Tim just get a 4x4 unit..aka TB0387...They ahve a slightly larger compressor wheel than the 2wd units and a bit bigger ID on the air inlet...unless you score a killer deal on a 2wd thing.
IF you find a 2wd one you'll have to pull the studs out...
You din't say which manifold you have but if ealier, look at the options of using the 2wd turbine housing---which is threaded M10 x 1.5mm---or if you have the "90+" maifold, you'll of course need to surface it and I have always drilled the mount stud holes out to the aforementioned M10 x 1.5mm.

Either way you'll have to re-clock the compressor housing and that brings with it repositioning the waste gate actualtor mounting bracket..Just so happens early old B21 T3 brackets are spiffy for that job....

Hook it up to a nice 3 " system and you're nearly done.

And as for actualtors: better genuine Garett something you know than some anodised pretty thing.

With THAT turbo---I'd stick with the "boring ol" T cam.

Docile enough to putter down the High Street down to the Kebab Palace... fun on old back B roads and fine for cruise to work.

And if you give 'er th' full wellie it is quick and strong right up to fuel cut...

Oh injectors

---Cossie Yellow or Blue (stock) safe to a real 275 Bee Haitch Peas.
Volvo dark green 80? good to 300.
"Dark Green" 803s good up to past 330 ---they come off Porsche 944T..

Wouldn't bother wif anything till i did just these thuings

Hi John,

Cheers for the reply, I had a feeling you'd be the man to ask!

Manifold wise it's a '90+' one, as the engine will be coming from a late 1995 onwards 940, 13mm rods, piston squirters, the lot. There's an engine machining shop in my village that recondition vintage Bentley, Rolls-Royce and Lotus engines, plus Mikina Engineering on the same site, so I'll get the manifold faced and drilled/tapped there.

I'll see if I can find a B21 Garrett bracket off the Forum here, see if a member has one Stateside or I'll see about fabricating my own. Indeed, I've read a few bits about Chinese/repro actuators, not my type of thing... Buy the brand I say.

T cam sounds about right, I have an A cam on offer to me so I may try that too. Block mounted distributor of course....

I'll get in touch with a few Ford Cossie chaps I know and see what they have available. All I see on TBricks is usually the larger HP turbos being recommended, but not much for the daily driver/scoot on motorway but will still be quite peppy and brisk type. They do recommend, if I can't find a Cossie hotside, the 'ATP Ultimate Housing'.. Which is another thing to look at. All they do recommend, is a .48 hotside, with the .50 or .60 trim compressor, that should flow quite well for what I want and application.

I have a Cosworth Turbo on my 240 as well. B230F engine with turbo bits added. Really nice with the V cam. But, the T works good too for DD.
Torque wise, its fine. Mine has the rare .63 A/R exhaust housing. Coupled with a normal 60 mm 60 trim .42 A/R compressor it can give a bit of boost by 2000 rpm and I think it is at the 8-9 PSI I set the wastegate to around 2500. Everyone who drives this car like the torque (and power of course).

Not sure if the original 240/740 turbo bracket is compatible with the Cosworth. It fits but not sure if it places the actuator where it belongs, the Cosworth and normal T3 turbines have different locations for the lever.
I'd look for the Cosworth housing, the ATP is probably more expensive by the time it is in the UK. To my untrained eyes the Cosworth housing has better wastegate placement, bigger flapper, etc.

When messing with cams, a nice ignition chip to match the cam is not a bad idea. You can modify chips yourself btw but it takes time.
 
I have heard the .55 and .63 housings can be better, but they're a little more hard to come by. Latter improves top end quite a bit (of course), but the .55 sits in the middle.

Sounds like a plan I may be interested in then - currently reading up on Passion Ford about the best combinations for the T3, not too much and not too little, came across this;

http://passionford.com/forum/ford-s...-t34-turbo-which-exhaust-housing-is-best.html

From what is being posted, the .48 or .55 definitely seems about right. ATP housing is ?180, I think, I'll check, and that's without postage. There's a Cossie housing for ?75/$110 on Fleabay in the UK, quite a few about, but will check out the Cossie Forums and Ford 'buy N sell' Facebook groups too.

http://www.ebay.co.uk/itm/escort-rs...912753?hash=item4af52c7a71:g:FzAAAOSwAKxWZCxZ

Have no chipping experience myself, would a Stoni/TLAO chip be wise? The engine is on LH2.4, of course.
 
Wasn't able to make it to that meet, I'm admin on the 'Volvo 240 Owners UK' group on there, I know a few of our members did go - quite a good turn out! Only been to Cosford for aviation reasons... My other past time and career is flying, so makes sense.

I may be going to Wellesbourne XM655 meet, possibly, but definitely RetroRides Gathering 2016. Anyway, back to Cossie T3 talk...

I take it majority of them are using T3/T4 hybrids?

Lord Athlon - what is your setup if I may ask? Would a. 48 or. 55/63 trim be ideal for my application? What compressor side would be best for what I'm after?

Tim
 
I vote .48 A/R turbine housing. If you stay with the same 60 mm exducer exhaust wheel, the differences won't be enormous (correct me if i'm wrong, driven with the 45-50-60 trim compressors on different cars with different setups so ymmv).
Will be a fast spooling (maybe not 15G style fast?) turbo. Those combinations will run out of steam before you hit the 300 hp mark, after that the 69mm 7 blade compressor seems like a good step up.

Remember that the Volvo coolant lines use M16x1.5 banjo bolts and the Ford (and rest) T3 use M18x1.5 cooling line thread. I adapted the Volvo lines, drilled out the banjo couplings with a stepped drill and modified some M18 banjo bolts for my T3 (made them shorter and added a wide groove where the water flows.

No, the majority were JUST the .48 turbine housing, a bracket and a actuator
Some got complete straight 2wd Turbos---slightly bigger compressor wheel than stock Volvo T3
Some got straight 4x4 Cossie units. Even bigger wheel and inlet hole on compressor side.
ALL but 2-3 got a/r .48

One guy in particular got both a/r...eh arse? .48 and .63...as well as my long rods and CP forged pistons in his ex-works Group A car down in Oz. As a ROADRACE car, he said he liked the .63 better eg with closer ratio box, on a circuit where its pretty much full wellie all the time.
Any other use, any wider box and I say .48
 
I ran one with a T04E 46 trim in a .70AR housing. The housing had what seemed like an early version of anti-surge machining, which i relied upon heavily in this setup. Didn't work tho. :lol: Would easily spool too fast and surge.

But I had to try!!!! :nod:

Kicked a$$ everywhere else. Was a blast on the interstate!

The newer anti-surge housings seem much better so if you are sticking with a .48 ar and questing for big power, I'd opt for a stg III hotside wheel.

If not, and you're not an idiot like me that's always trying to find some ideal nexus between a fast spooling setup and bigger numbers, TAKE JOHNS ADVICE!!!

And, as mentioned before, the bracketry can be tough. I've had a Dickens of a time getting the wg actuator setup on both of the cossie setups I've run.
