So I searched on this and got some conflicting information.

 

I've got a '00 SOHC that I'll be doing a nose job on and I would like to clear this up before I order parts. Looking at the front of the SOHC, It seems like it's possible, but I"m not sure and I don't have the 2.2 apart yet.

 

I've read that the "old style" tensioner is a better design the the "new style", the old style being on ej22 of pre non-interference design. Some say you undo the bracket holding the old one and bolt the whole works on a newer engine. Some say this doesn't work because there is no place in the case casting for the bolts.

 

But none of these threads identify which engines are being talked about. So maybe some clarification from those that know?

 

 

So the three possibilities that this swap might be applied to are:

 

phase II EJ22

DOHC EJ25

SOHC EJ25

(this doesn't include the 6 because they use a chain correct?)

 

Thanks!!

yes, the new H6's have timing chains.

 

not positive on the rest. but i wouldn't be surprised if you can't install the old style onto Phase II engines. They have completely different heads and stuff.

if you check out these links to www.subarupartsforyou.com you will see that the old style was used 90 - 97 2.2L and 96 - 98 GT w/ 2.5L .

 

2.2L old style tensioner

 

2.5L old style tensioner

 

(same part same part number, if you read the part description it list the years it fits.)

 

now this means it can also be used on outbacks 96 - 98 since they used the same block as the GT, but another page seems to show that outbacks 96 - 09 used the ''new style''.

 

2.2L & 2.5L new style tensioner 96 - 09 - (vin required for 96 - 98)

 

 

so the new style can be used on the 96 - 98 2.5 blocks, and probably on the 2.2 blocks but why? the 96 - 98 blocks can use either tentioner?. i have never looked at a phase 2 block so some one else will have to chime in.

If you use the complete setup, bracket that bolts to the block, tensioner and pulley, all the EJ ones interchange, except the wrx/sti turbo ones. The turbo cars have an extra small pulley on them.

 

I've used new ones on old engines and old ones on new engines, just use the complete setup.

 

All the EJ blocks are the same externally. Everything just bolts on. I have a 93 legacy EJ22 block in my 02 WRX and everything bolted right on.

Thanks for the info.

nice, thanks subaru 360 and will, that's awesome info .
