Does anybody know apart from the up pipe and headers whether a VF36 or VF37 twin scroll turbochargers require any further modifications to be carried out? My car is a 2006 2.5 WRX.

I think I might have read somewhere that the oil sump might also need changing but again I think this might only apply to 2 litre engines.

From memory,

1, Downpipe.
2. Uppipe.
3. Headers.
4. Sump. due to shape of headers/uppipe I think.
5. Smaller oil filter.
6. Twin scroll turbo VF36/37.

Bloody expensive route to go down if you already have single scroll!

As above 1-4 and 6.

Looks like unless I can get the above for a good price I might have to reconsider my plans or find a written off JDM STi or spec C/D.

same as above, you could get all the parts including the turbo from japperformance the cost for this off them is 1000 hope that helps with you

No need to change the sump - the 2.5 engines used the same one as the twin scroll cars.
Have a word with RobinSherwood who has done this swap on a spec D.

I have recently done this conversion on a 2ltr using all the parts listed above apart from the Oil filter as its the same.

However I was advised that the VF37/36 is too small for use with a 2.5 due to the extra cc's. This info came from David @ APi & Bob Rawle It would be worthwhile checking with them to check suitability.
