Bean Posted April 15, 2016 Report Share Posted April 15, 2016 Picture of the intake side of my Forced Performance turbo. I'm actually thinking of the 2pc exhaust side for this built T3/T4 hybrid since it would be the easy way to do a 3" downpipe to a new muffler.

ganun Posted May 6, 2016 Author Report Share Posted May 6, 2016 Wonder the difference on presssure tap location, some have it at the outlet , your picture shows it at the start of the scroll? 1st pic is early .48, tap at start. 2nd pic 89 .48 tap at outlet.

ganun Posted May 6, 2016 Author Report Share Posted May 6, 2016 Just got a great looking rebuilt center section from Durabuilt Turbo in Chicago, $250. Looks like a lot of extra work to clock it correctly so the oil inlet and outlet AND intercooler and manifold connections properly line up! Think this is the procedure I'll use: 1) Leave the cold and hot housings loose so they can spin 2) Bolt turbo to manifold 3) assemble finger tight EVERYTHING , ex mani to head, intercooler, oil lines in and out, wastegate actuator 4) snug a few of the accesible housing bolts 5) remove all again from engine to tighten and lock the housing bolts 6) final reinstall Whew!!

Bean Posted May 6, 2016 Report Share Posted May 6, 2016 Hi George, Plan sounds good unless you already have an assembled turbo in your collection. Pressure tap - I'd use the one off the outlet, as that should be as close as possible to the intake pressure. I tried using the intake to get a cleaner signal for the wastegate - but it spiked too much - probably the long boost lines. Rabin Quote Link to comment Share on other sites More sharing options...
V-M Posted May 22, 2016 Report Share Posted May 22, 2016 2 piece ones are old <-85 versions, some replaced after that year cause those are fitting new assembly. Only reason to keep old one is if stick on original exhaust. Sold last non cracked original 2 piece garret to Danmark. Have still 5 original 2 piece turbos and all of them are cracked same way. Same problem is also in other t3 and t4 (t4oe) type turbos. They all cracks on wastegate and some one also in housing. V-M Quote Link to comment Share on other sites More sharing options...
Bean Posted May 23, 2016 Report Share Posted May 23, 2016 Hi VM, When you get a chance can you take pictures of the crack? And do you know if the 2pc housing is the same pattern as the Ford housing? Rabin Quote Link to comment Share on other sites More sharing options...
V-M Posted June 7, 2016 Report Share Posted June 7, 2016 Here is some pic. I dont know ford pattern. Do you ment for exh pipe side or manifold side? Many turbos have pipe side fitting same as n9t but none have same on manifold side. V-M Quote Link to comment Share on other sites More sharing options...
SRDT Posted June 7, 2016 Report Share Posted June 7, 2016 Looks a lot like KKK flanges, the 205 Turbo 16 got something like that with a Ø56.2mm opening on his K26. Quote Link to comment Share on other sites More sharing options...
Bean Posted June 7, 2016 Report Share Posted June 7, 2016 I meant pipe side - Ford's use a very similar 5 bolt housing with the same wastegate set up. Engine side is likely Peugeot specific, maybe the same as 205 since it was similar years. Size wise it's much closer to a T25 then the bigger T3 flanges. Dabbled with the idea of changing it to T25, but I need to see how "weld-able" the exhaust manifold is first. Rabin Quote Link to comment Share on other sites More sharing options...
ganun Posted June 8, 2016 Author Report Share Posted June 8, 2016 Looks like its easy enough to remove the 5 nuts and take a look for the big time cracks! Maybe they are due to abuse. Quote Link to comment Share on other sites More sharing options...
SRDT Posted June 8, 2016 Report Share Posted June 8, 2016 Volvo did something close: But again the KKK turbos can probably fit better: Speaking about the 205 Turbo 16 the road going ones where made with as much off the shelf parts as possible, making only 200 of them means you won't ask for a custom exhaust housing. They used the fuel distributor from a Porsche 924 turbo and the turbo was probably at best an hybrid made with two existing ones.ded Quote Link to comment Share on other sites More sharing options...
Goce Posted June 8, 2016 Report Share Posted June 8, 2016 I'm no expert in the turbochargers, but that looks like a standard T3 turbo, with a different bolt pattern on the hot side, similar like the peugeot 1.4hdi pattern. Quote Link to comment Share on other sites More sharing options...
Bean Posted June 9, 2016 Report Share Posted June 9, 2016 Volvo has the same bolt pattern as a T3, the lip just needs to be machined off and a T3 bolts right up (or you can use an adapter inbetween) The 205 turbo looks like a T3/T4 hybrid with its much larger compressor housing, but exhaust housing looks the same for sure. Earlier I posted a pic of my Forced Performance turbo which had the compressor housing machined to fit the larger T4 compressor wheel. Not usually advisable, but since it was done by FP I'm hoping it was well executed. (You can tell only by the inlet diameter which was enlarged by ~10mm) Rabin Quote Link to comment Share on other sites More sharing options...
