Td05 turbo

[Shayne mordecai]

Hi all I'm swapping my td04 for the td05 on my subaru ej20 engine and the turbo won't bolt up as its hitting bell housing can't understand the problem as its ment to be an easy swap any know or had those problem before tia

Stock subaru (Mitsubishi made)  tdo5 16g should be a straight swap . As long as they're both the same "entry" and fitted with the correct oil and water feed lines / banjo bolts for the turbo .... so I'm guessing it's a aftermarket turbo ?

With some of the early md , blouch ect big Garrett based stock location turbos , they used to cut some of the bellhousing away . As the compressor housing used to foul on the tmic bracket mounting bolt hole  (edge of the bellhousing) .

 

These were big 450hp + turbos , so they were running fmic's and didn't need the tmic mounts anyway . Saying that if it's a big tdo5 20g it should still fit (mine fits fine ) .

 

Tbh anything bigger than a 16 g on a any stock ej20 (other than the sti ej207 onwards ) is too big for the engine and 5 speed drivetrain hp limits .

Just thought I'd mention , in case you wasn't aware .That any change in airflow/fuelling will need to be mapped in straight away,  as fitting a bigger 350hp + turbo will flow much more air at a different rpm .

So fuelling /timing and boost targets would need adjusting accordingly , to not damage the engine .
