2005 legacy turbo specs.

[mondo]

What specs are the turbo on a 2005 legacy manual?, a bit of net searching says its TD04, twin scroll of course, others say its a vf38 same as the auto.

Also who can recommend a turbo shop to rebuild it.

Thanks in advance!

Manuals have the td04

Vf38 is one of the worst turbo Subaru has used. Bolts directly onto inter cooler. Not worth rebuilding but then again secondhand is around 1500 mark for them

Ok then its a td04 twin scroll, anyone had to get one rebuilt?

parts arnt a issue good turbo better than the vf38 but the vf38 can also be upgraded

What\'s a good, simple upgrade for vf38?

[vorigan]

find any vf core thats still in good nik like a vf29/28/24/23 and i machine that into your housings you may not know but most of these aftermarket bolt in turbos use garrett gt cores to which you can no longer buy parts and arnt cheap nor overly responsive compared to the stock unit unless your after big power and with that comes lots of other things, for most sub owners they want stock but a little more power and most of the owners are around 200-230kw wheel and are more than happy with that and this isnt directed at anyone its just facts.

what turbine housing does the vf38 normally take? is it a p25 type arrangement? similar in size to the older p18 steve?

What im asking is.. by putting the earlier core into this later housing, is the housing sizes (AR) hot and cold side equivalently the same between the early VF and the vf38 or is the vf38 markedly large smaller in either hot or cold housings?

putting in aftermarket turbos certainly takes a fair amount of other stuff, and modification and $$, and they do make a heap more torque and power. agree the vf\'s are generally acceptable to run up to and around 220-230. but i disagree aftermarket units are unresponsive - CS has seen a number of results across a few different branded units have really nice curves and torque in good places. CS also seen factory turbos not perform across various platforms so blanket rules shouldn\'t be applied i feel.

A well thought out set up with car use and ultimate goals in mind before you start poking round is a smart idea, imo.

as above, all general discussion and not directed at any individuals car great or not, nor specifically about a garrett / vf comparision, CS has seen wider results than that.

the vf38 is a p25 twin scroll housing but does not swap with the vf36 bolt flange is different you cant get parts for the vf38 i can get rebuild kits but no shafts and wheels thus why i used the early cores which takes a few hours maching to match up you end up with stock response but gain some power in the process ive done well over 60 of these from sub dealers to joe public by fair cheaper than any other option

[funkytown]

yer i get it, was just interested as to what type of relative hybrid you end up with

vf38 comes in autos from 03-05, tdo4 comes in manuals from 03-05. 06-09 bp and bl legacys use vf44 turbo.

you can get the rebuilt kit from ebay

you will need to get your turbo balanced after repairs.

what about the comp wheel? and as per most when they explode they distroy the rear turbine seal area in the core and they also use a stepped core thus when theres rear main bearing damage you cant over size them thus you need another bearing housing, what then?

[mondo]

Lots of info, thanks.Manual is td04hla-19t.I\'ve managed to source a complete brand new rolling center assembly, so it will be an easy swap into the housings

Interesting about the autos......mine has VF36 on the turbo label

So presumably your 38 already blew up. Can\'t imagine they ever came out of the factory with an STi Spec C turbo ...

OK.....I\'d better check again tomorrow. I thought the swap would require the STi headers as well, would be sweet if it was though

and intercooler also as stock has the turbo bolt directly to it
