Im sure my turbo has been upgraded, just looking at it now and measured the diameter of the downpipe coming off it 4.5" is that normal?

 

Well, the downpipe has been upgraded!

Usually there is a 2.5-3" round pipe bolted to the turbo, with an offset, ovalish flange. Some aftermarket downpipes take full advantage of the flange and are oval in shape, usually 3" by about 5" - called open neck design.

All uprated turbos that are a direct replacement will have the same design exhaust housing as the original, regarding bolt holes / downpipe fitment.

Your OE turbo should be a TD04, there should be a stamp on the compressor cover.

Didn't the MY95 imports have the TDO5H turbos fitted?

 

JDM 'Wagons were always fitted with a TD04 of one type or another. They also have a slightly lower output of 220PS with maximum torque at about 3500RPM.

most import wagons come with a td04 but you can get some that come with the tdo5 just have a look on your turbo and you should be able to read off the turbo.

 

The only JDM 'Wagons with TD05s are STIs.

 

my last wagon which was a 1994 had a td05 turbo on and it was just a standard wrx and not and sti at all but the one i just picked up this monday which came from japan has a td04 on it so i dont know what to say?

 

I HAVE PHOTOS OF THE TURBO AND DOWN PIPE I CANT SEEM TO SEE ANY WRITING ON THE TURBO, ITS PRETTY CROWDED, WHERE EXACTLY SHOULD IT SAY TD04? ALSO WILL A STANDARD CAT FIT MY EXHAUST, ITS ABOUT 3.5" AND MUST APPOLOGISE PEOPLE, THE DOWNPIPE FROM THE TURBO IS 3.5"ISH NOT 4.5 LIKE I STATED EARLYER, HAD A BAD NIGHT WAS ABIT TIRED. my email address is misty.moo@virgin.net to see the photos i dont know how to put photos on this sight, so if theres anyone who would like to see them then please email me and hopefully you can tell me a standard exhaust system will fit my existing turbo.

 

It was definately non-standard.

A standard JDM WRX 'Wagon (of this age) only has one cat; in the downpipe. What appears to be a cat in the centre section is actually a resonator.

Id say that 'I hope this helps' but I suspect its just adding to you problems...

JDM wagon 92-96 had td04
UK wagon 93-96 had td05

 

Well, iv'e learn't something new today, as i did'nt know that !

Rob

 

ok guys ive been very busy and as a result ive found that the turbo i have is indeed a TD04 and the flange is offset ovalish outside measurement id say approx 5" so im guessing a standard system will fit:-) i have a exhaust system minus rear box, i need a rear box has anyone a spare to sell or anywhere i could get one anyone???

 

Ebay is your friend !

Rob

 

already looked, there are no original rear boxes or systems for a 95 turbo at the moment up for offer typical when i realy need sumet this always happens, are they expensive from subaru?

 

everything on the car was standard but the turbo even had the twin pea shooter exhaust on it.

 

As I keep saying; ALL early non-STI GF8s had a TD04. If yours had a TD05 fitted then it was changed along with the ECU; it wasnt standard. All GF8s had a smaller faster spooling TD04 turbo engine making 220PS, with peak torque at 3500rpm as opposed to over 5000rpm on the TD05 equipped GC8s. GC8 autos also have this engine fitted.
