Ahoy hoy-
I'm planning an unorthodox engine swap but am in need of engine dimensions before I can proceed any farther. I'm looking for Length, Height, Width of block + other immovables such as distrobitor, pulleys, etc (not things like plenniums and exhaust which can be made to fit) and weights if possible for the EJ20 and EJ22 motors, or even the 2.5L variant...

Any help is greatly appreciated!

inches, ft, mm, cm, lbs, kg...what do want this measured in? i can get you pics and measurements from a ej25 that have laying around my garage....

 

Inches would be great! I used to have an EJ22T that was built to oblivion, but I can't find any record of me measuring it...

Thanks!

reaaaallly? what body style was it in, how fast, what kind of turbo....c'mon don't tease us here. the ej22t is like the holy coveted subaru engine

 

The car was a '91 Legacy Turbo WAGON - rarest of the rare - which was bought off a guy who owned a liquor store for $3000. I don't know if it was built via some kind of dealer special order or what, but it was origionally the EJ22T with the manu-matic 4-speed transmission which I later swapped out for a 5-speed manual with Viscous Coupling. It came to me in a somewhat dented state with all the power options minus sunroof and 160hp IIRC...

Over the 2 years I had it, I added 2.5l open-deck heads with Cobb tuning con rods and pistons. I had ported the heads myself with a dremil tool, put a T25 (I think?) auto-recycler Mitsubishi turbo on it with a Starion FMIC. Exhaust, intake, and turbo piping was all hand-fabbed by me. It has been a long while since I have owned it and the details are sketchy in my memory, but I think that it was making something like 345hp on 18psi.

At its prime, the wagon was super-coveted, super-fast, and super-sleeper (retaining the stock steel wheels). The car ran approximately mid-low 14's in the 1320 -- I still hold the record for the "Short Woods" downhill with that car and I haven't lived there in almost 4 years!

The car was mortally wounded due to being stored - without my knowledge - in a parking lot that flooded after a hurricane when I moved here to Florida. I was able to barely drive it for another 2 months or so before it finally kicked the bucket (running on 2 cylinders and swilling oil).

If the motor will fit in my current project, I will do what it takes to build another one and swap it in.

IMO, the world IS flat...

Hrm...very odd....

-Subaru didn't sell the Legacy Turbo in a wagon version until 1992 and all factory turbos came with glass sunroofs, it couldn't be deleted.
-The stock bottom end on the EJ22t block includes all drop-forged internals, lighter and stronger than anything Cobb builds.
-Although stock 2.5 heads flow very well and decrease the compression ration on the 2.2t block they have problems floating valves at higher RPMS. The work Cobb does to their Stage 3 2.5 heads is pretty sweet and it increases the RPM capabilities of the heads to eliminate the risk of valve float.

 

This is why I'm not sure about if it was some sort of special order or engine replacement or what. All the documentation that I had found said that it "didn't exist" and yet I had it in my garage - it would make more sense to be a swap since my wagon was identical to all of the other L's from 1991 except for the EJ22T and "Turbo" badging.

I was unaware that the stock internals were stronger than aftermarket - that's kind of a downer. I bought COBB ones becuase I didn't think that ANY stock internals ought to be exposed to 18psi... At the time, everyone I had talked to suggested that I replace the rods and pistons, so rather than risk blowing up what I had, I did. Does this mean that I may have spend a lot of money for nothing?

IIRC, the 2.5 heads were SOHC, which I think is why I swapped them in. It wasn't really that often that I would wind the hell out of the enigne and I wanted lower rotating mass for an overall quicker response (every bit counts to counter turbo lag). I think that the only parts I got from COBB were the internals, but it is possible that I did buy the heads from them as well. I do remember that the heads and internals were the two most expensive things on the car and together totalled more than the purchase price. At any rate, I don't remember ever experiencing any valve issues before the flood...

Pardon my sketchy memory, as this was several years ago and very much to my chagrin, before the days of affordable digital cameras. I have absolutely no pictures of the car anymore, and I really wish I did!

If I find measurements for the EJ and find that it will fit my project, should I stay with the stock internals rather than spending more money on aftermarket parts? ALSO: Which transmission came with the EJ22T from factory?

THANKS!

EJ22t bottom ends are stronger than any other Subaru block ever sold, with a set of 2.5 SOHC heads and a '99 & up 2.5 RS top end you can run 30 psi reliably without touching the bottom end. This is a result of the lower compression ratio acheived with 2.2t block & 2.5 head combo. More boost-less CR=more reliable! I wouldn't spend money on bottom end internals unless there was something already wrong with the block you end up with.

The tranny's the EJ22t cars came with were identical to the trannies in the other cars from those years in regards to gear ratio's and final drives. The main difference between the two were that the EJ22t tranny's internal were all shot-peened for strength. There were two tranny's availible on the EJ22t Sedan, a 5-Speed Manual or a 4-speed auto with an electronically controlled "sport-shift" feature, the EJ22t equipped wagons were only availible as an automatic from the factory. The 1991 model year got the best feature...they came with a 3.90 Rear limited-slip differential. The '92 - '94 models didn't get this feature as a cost-saving measure by Subaru.

 

WOW, you learn something new everyday....Professor Opie has spoken!

 

Do you mean on all AWD 1991's?

I was totally unaware of how strong the internals were of that motor... Makes me feel like an idiont for laying down all that cash for COBB parts when my origional parts were fine.

Thanks for the great input!

Does anyone have any measurements for the EJ series?
