Cylinder head rebuild EJ25D
my first attempt at rebuilding a Subaru cylinder head. i may not be perfect
but at least i didnt have to pay someone to do it for me.
7-Bolt Shortblock Failure - Full Diagnosis
If you are your own mechanic, there is no more important character trait
worthy of development than the ability to own your mistakes. That's where
the line is drawn between good mechanics and bad mechanics. It's not the
failures but how they deal with them that measures their ability.
In short, it's not easy to admit you did something wrong or were negligent.
But if you don't own it and talk about it, it doesn't get fixed, and
nothing positive can come from it. It was my quest to overcome my clutch
issue that lead to the creation of a video. That video is the textbook
perfect guide for how to correctly install a DSM transmission.
Crankwalk as described is caused by a casting defect. This was not a
defect. This was preventable. A lot of people would find something like
this and not tell anyone out of embarrassment. I'm not ashamed. It's my
fault. I got good use out of this engine and it was tough enough to make
it 48K miles since the last rebuild despite my abuse. I'm here to tell you
if you bought a used car that's had its clutch replaced, or if you ever pay
someone else to do it... make sure it has this bolt. It's stashed away
between the starter and the transfer case, so it's hard to see. Make sure
all of your bell housing bolts are torqued properly because fastener
problems can destroy your shortblock, clutch and transmission. If your car
fails because of a mis-aligned transmission, you have no reason to blame
It wasn't until I bought my next AWD car that I discovered there was a
smaller bolt on the other side of the block. I destroyed 3 transmissions
in the GSX first. With the damage already done to my crankshaft, I then
lost a shortblock. It's an ounce of prevention that's worth metric tons on
your bank account.
Grade 10 M8x60 bell housing bolt = MD706012. It gets 22-25'lbs of torque.
Owning my mistake permits me to learn from it through con$equence$, and
never repeat it. What good would it have done anyone else for me to learn
this lesson and not share it? That's why I'm providing this video to all
of you. Sharing it can perhaps help someone else avoid this costly
mistake. This is the final chapter for my 7-bolt, and this book is going
back on the shelf.
Here are some valuable resources if you're trying to read bearing damage:
And of course, now that I've covered the complete oil system, transmission
and driveshaft series of videos, you now have all the tools necessary to
ensure your 4g63 lasts a very long time. Whether the casting defect
exists?... or it's all caused by a bolt, or the harmonics, or whatever...
Sure, crankwalk exists and it's horrible. But with the small amount of
movement required for your crankshaft before it contacts the block isn't
far enough to make your clutch drop to the floor when you turn. You'd be
hearing woodpeckers and jackhammers on the crank long before that clutch
pedal would fall to the floor. Some people are going to hate on me for
saying that. That's fine. I believe all of the people who experienced the
clutch pedal issues had fastener problems on their bell housing.
DSMs get a bad reputation for this but we can change that. Crankwalk is
never the cause of your engine failure. Crankwalk is always a symptom of
the real problem. It's your disease that makes you deny it's your fault.
You've got the 'itis. DSM-itis.
Whenever you dig deeper, you'll discover what applied all of those thrust
loads to your crankshaft to begin with, and it's not going to be a casting
defect that moves your crank .101". Mine only went .014", but all of the
same parts failed.
PLEASE tell me in the comments if you find this bolt is missing from your
2005 Subaru Outback Engine Replacement
This is my 2005 Subaru Outback with the old engine removed. I'm talking to
a mechanic at P & L Motorsports in Franklin Park, Illinois about the
procedure to replace my ruined motor with a new short block and rebuilt
Fiat 500 with Subaru engine
This is a Fiat 500 modified by ZCars Ltd to the specification of a customer
from Greece. The design brief was to fix his 500 in an interesting way so
that it would have more useable power to enable him to drive his family
around town in comfort. Whilst he was tempted to have the Suzuki Hayabusa
conversion ZCars also produce he decided that he wanted to keep the rear
seats. As that is where the 200bhp motorcycle would be installed that
option was ruled out!
The engine is an EA81 Subaru engine (1800cc flat 4) which is quite an old
engine although still widely used as an aviation engine we are told. This
engine was used due to its simplicity, power and torque characteristics and
not least its size and shape. This was mated to the original gearbox with
clutch and drive shafts up rated. Also up-rated were the brakes with discs
all around and the suspension at the front. The transverse leaf spring was
removed and adjustable alloy dampers were used with coil springs. A new
front subframe was fitted to allow the use of wishbone suspension arms.
Obviously as it is a water cooled engine, radiators were required. This was
inserted into the front boot space (trunk) and water pipes run underneath
the car. A new stainless steel Exhaust
finished the conversion and new wheels and tyres were fitted as an optional

Subaru Legacy JDM EJ25 swap
1997 Subaru legacy wagon, blew the stock engine on the crank due to oil
pump failure at 245000 km, got a jdm ej25d n\a engine, changed the head
gaskets on it and stuck it in the car. It has headers on it and a muffler,
still a couple Exhaust leaks to fix.
Kept the japanese intake manifold since it does not have egr system and is
better flowing. its a great winter car !

Subaru TT Challenge 2
Subaru returns to the world's most formidable racetrack, the Isle of Man TT
Course, with the all-new 2015 Subaru WRX STI to set a new lap record.
With the sub-chassis, front clip and roll cage welding complete, team
Leavitt brings all three components together giving shape to the car.
Rodney and Colton MIG weld at the same time to increase production while
keeping a close eye on the heat input and metal draw, (which is also an
important step in choosing where to sit)!
DirtyImpreza.com - Project Rally RS Episode 3 - Rollcage
In this episode of the DirtyImpreza.com Project Rally RS (PRRS) build we
cover the events from much of 2008. The 2001 Subaru Impreza 2.5RS was
stripped down, seam welded, caged, painted, and re-assembled with a donor
motor and transmission from another 2001 2.5RS.
The roll cage was constructed by Jackson Rally and is Rally America and
NASA compliant (built to FIA Article 253 specs). It has been overbuilt in
some areas for extra safety and rigidity. The shell has been seam welded
around the struts, transmission tunnel, cabin floor, and wheel wells. The
roof skin was replaced with a JDM roof to completely delete the USDM
Its been a long year, but finally we have a running rally car! There are
still numerous smaller projects that need to be tackled before this car is
stage rally ready, but some of the biggest milestones have already been
reached. Thanks goes out to Kyle at Jackson Rally for his amazing
fabrication work, Scott at California Auto Collision for painting the
inside of the car, and the dedicated DirtyImpreza.com members who
tirelessly helped to get this car where it is today.
Note: For those of you who may have been following the build this episode
might be a bit confusing, and you may ask Where did this other RS come
from? Basically, the original 2.5RS was scrapped because it had extensive
rust, and a severely damaged frame (which was revealed during its initial
tear down). The decision was made to buy another identical 2001 2.5RS with
a blown motor but no frame damage or rust, and transplant the vitals from
the other car into this one.

Subaru EJ257 STi shortblock NA build
UPDATE: (Dec 5, 2009)
Seems that this video has gotten quite a few views. The reason for the
delay in adding the turbo kit was that
grad school is taking priority at the moment (time-wise and financially,
too). This project has obviously been shelved for a short while. I should
be graduating by mid-2010. Maybe I'll make an updated video with the turbokit if there's any interest. ;)

So far I've established that I can run pretty close with a stage 1 2.0L WRX
(only 3 car lengths behind by 90mph).
1. I'm running stock engine mounts and Exhaust hangers. :P I should be upgrading those
2. The blinking red light behind the CAI is a Perrin rear O2 simulator.
3. I'm planning to piece together a 6-8psi turbokit for this over winter.
