4 years I waited for one of these to show up used, this was made from cusco before it was a household name in the Subaru world and I have the original pamphlet with cusco head office address on it lol

thank you, try to copy the sedan but ill tone the motor down for there wagon
weight, my sedan never came with it that's why its so light weight
many parts have come in for the motor now its time to dig a ej22t block out and build it while I wait for paint work.
Wossner Made in Germany forged 22B pistons and connecting rods, STD size pistons means no messing around with my ej22t block & machine shop .... I should have just built all my ej22T this way


ACL racing STD size bearings not race version, STi spec-c oil cooler adapter, proper water pump with single port and old school timing belt tensioner from the ej22t aka the motorsports racing tensioner.

aurora asm-10T military aviation spec front control arm spherical bearings, this will all me to run longer aka normal Subaru length CV axles and also camber. I won't need to modify the front crossmember to except XT6 front control arms.

lots of mess *♂️

so since quarantine I've been busy in the shop.
picked up a Full Race twin scroll headers to match's my sedan set up

Borge Warner EFR 7163 takes care of the turbo with internal gated & bov

some 4 pot / 2 pot action to match the sedan set up, also got stainless steel pistons made up front and rear for thermal and rust prevention


got a personal specific torque plate made for my EJ22T blocks, proper thickness of the head was used so it match torque strengthens


torque plate results, yes it makes a difference for sure


time to assemble the wagon engine, the the spare motor for the sedan or the wagon lol



what its going to look like


can't have a new motor with out a good transmission, so I took apart my spare STi 6mt to change some synchros so its smooth like butter.

all primed up and ready for the single stage white paint job to match my sedan



here is the pistons I made and got wrinkle red powder coated my valve covers

so after trying to rebuild my steering rack it seems that seals are impossible to source so !

The old school Subaru guys are going to find this one interesting !
1986-93 GL-10 TURBO engine Crossmember
1991-04 New age Subaru Steering rack
what we have here is a option that I can take advantage of
18:0 GL-10 steering ratio
15:1 STI 2004 steering ratio ( my new rack is on the way 😁✌️)
