K thx man. It made me depressed to see how big the EJ20G ports are on the head knowing I cant use em. Wheres a good place to get Engine specs other than Notable members? I looked up some 94 WRXs and pretty much figured out how Im gona have to do my intake w/ the JDM turbo. What about a tune for UTEC?

All turbo ports were that big until the end of the 2000 model year. The first heads to feature smaller ports for better torque and emission were the 2001 GD/GF WRX models.

As the saying goes as long as I'm replacing the waterpump I might was well do the timing belt. I found some lovely but useless kits on ebay that I wisely chose not to buy.

After using the search button quite a bit I discovered to replicate the parts in the ebay USDM timing/waterpump kits I need :

Timing Belt and Timing gear from 93-96 legacy 2.5l ?
Tensioner from 93-96 legacy 2.5l
Water Pump from 02 WRX
Cam Seal from 93-96 legacy 2.5l

I though I would doublecheck my information is this all correct?
Also I need to know what USDM year and model I should be getting the

Front seal ?
Idlers ?

Little help would be appreciated. Much thanks in advance.
Hey buddy i got a 96 jap sti and need to do cam seals water pump timing belt... did these parts above work out for you...
i think my ej20 sti should be about the same right..?
cheers

Yeah those parts worked prefectly save for the waterpump which required some modification to plug a coolant bung for a coolant/oil heat exchanger that my ej20g doesnt have. I found a tight fitting bolt and jb welded it into the hole. Then I completely mig welded it to the bung to make sure there was less then zero chance of leakage. Everything else was a perfect fit.

I know this thread is a year old...is there another water pump that is the same? I would greatly appreciate the help!

I just double checked and I can tell you for certain that a EJ253 water pump will NOT work, though I know that doesn't help you much.

the 02 usdm wrx waterpump will work fine if you get the 02 wrx water/oil heat exchanger that the extra coolant bung goes to.

Bonus: the Heat exchanger is almost as good as having an oil cooler.

Most early EJ20G engines already have the heat exchanger...

Default EJ20 JDM Legacy Twin Turbo (EJ20R)

I am a bit of a newbie here, but wanted to share something I found since there seemed to be a gap when I searched recently.

I have (to the best of my knowledge) an EJ20R, which came from a JDM Legacy Twin Turbo. I am using the block to rebuild a standard 2005 EJ20 USDM engine (block cracked), and I'm not there yet, but just got through figuring out the bearings.

Obviously, there are likely to be many other situations, but this engine is a phase 1 engine (thrust #3), and I went through a couple bearings. The ones I got to work finally are: ACL 5M8297HX Std. The problems I was having were that the bearings that I kept getting recommended were too thick. Also, there is a bit of a lip around the thrust housing, but when I dropped these bearings in, it fit like a glove.

you can see the specs here, and how they differ: http://www.aclus.com/content/ACL07(1).pdf

Anyway, I don't mean to dispute any of the other recommendations in this thread, just wanted to add my findings in case it helps someone else out!

What were the part numbers of the bearings you tried out before those ACLs that worked? The HX give a marginal increase in oil clearance and in most cases H bearings would work just as well.

I'd probably chalk taht up as an ACL QC issue as of their post-bankruptcy issues.

I previously used the 5M8299H .75, although I think you're likely correct that the .25 may have worked.
