1999 Outback DOHC but Phase 2 4EAT?

[serrs]

From reading this forum and a few others, I thought I knew that I had a Phase 1 setup on my 1999 Outback.  It is DOHC which I thought made it a Phase 1.  During a JDM swap I wanted the JDM transmission too.  After getting everything in there the transmission connectors don't match - 17pin vs 13pin.  (Please don't make fun of me, just take pitty)  My old transmission is a TZ1A2 and the JDM is a TZ102.  And from another of johnceggleston's posts it indicates the TZ1A2 is Phase 2!

 

So I have a few questions:

So did my car come with a Phase 1 Engine and a Phase 2 Transmission?

(If it's all Phase 2, I'm confused because I thought that would be a SOHC??)

 

I've read several times not to mix-match Phase 1 and Phase 2.  But I need reassured, if it is a Phase 2 ECU it is ok to mate it with a Phase 1 engine as long as you keep your Phase 2 intake manifold?

 

FYI:

TZ1A2ZJEBA-WZ 1999 OB

TZ102Z1DBA-KC  ?   JDM

 

I understand the front differential gear ratios need to match, and it's very hard to know with the JDM.. Another thread here mentioned counting the teeth, is there another way to determine it?  I'm pretty certain this AT is not going to work for me, but for it's next home.. I need to know.

JDM = can O worms interchange is very limited

Yeah, Phase II trans started in 98.

 

Phase II engines started in 99 with the forrester. 

 

However, the Outback for 99 retained the Phase I intake and heads (the block is a Phase II, #5 thrust bearing)

 

99 is the new 87.

yes

if you start with a phase 2 trans you have to stick with a phase 2 trans.

 

TZ1A2ZJEBA-WZ 1999 OB = phase 2

 

TZ102Z1DBA-KC  ?   JDM =  phase 1, don't know the ratio.

in the US, a TZ102Z2DBA it would be a phase 1, 97 - 98 outback auto trans w/ 4.44 ratio.

it is definitely a phase 1 trans, but i do not know of any way to identify the ratio except to count the teeth on the ring gear.

but this is a moot point since the electronics are different than yours.

the intakes do not swap, phase 1 to phase 2.

for all practical purposes you cannot swap a phase 1 and phase 2 engine .

you can swap short blocks and keep the original heads and intake  though.

Thanks so much!

Your information is much appreciated.  I found more where the JDM AT came from... it was identified on the JDM engine in white grease pen (I assume from the exporter) BG9 (Japanese Outback?).  The "DBA" on the end of the AT would indicate one year older Outback than mine since "D" is one year before "E".  The engine also had a coil pack that is the same as a 1998 Imprezza RS.

 

Anyway thanks, I'll count teeth eventually so I know what I'm trying to sell.

no, not accurate.

but you are beginning to get the feel of it.

 

the DBA (97 - 98) is one year younger than the CBA (96 - 97).

but the EBA 99 is altogether different, a phase 2 trans, since it is a TZ1A2.....

not the TZ102 than they used all through the 90s (90 - 98).

 

good luck.
