4G63 back from the ashes---First half of engine rebuild
After over a YEAR of promises that I'd get this vid done, I went halfway and got the engine pull and most of the shortblock work edited and documented. Here for your viewing deliciousness is PART 1! (link to torque specs for the engine here: http://bit.ly/17KDEED)
CRANKWALKED? 7-bolt teardown 1080HD
Audio track by RojoDelChocolate.
Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag
passes, a half dozen Dyno sessions, 4 transmissions,
3 clutches and 10 years of hard all-weather use.
Now this is a story all about how
My bearings got flipped-turned upside down
And I'd like to take a minute just sit right there
And tell you how I used to mix and burn my gas and my air.
In RVA suburbs born and raised
On the dragstrip is where I spent most of my days
Chillin out, maxin, relaxing all cool,
And all shooting some BS outside with my tools
When a couple of guys who were up to no good
Started running races in my neighborhood
I heard one little knock and my rods got scared
And said "You put it in the garage until you figure out where..."
I Begged and pleaded that it not be that way,
But it didn't want to start and run another day.
I kissed it goodbye, because the motor punched its ticket
I got out my camera, said "I might as well kick it."
Crankwalk yo this is bad
Drinking metal shavings from an oil pan.
Is this what the rumor of crankwalk is like?
Hmm this won't be alright
But wait I heard knocking, grinding and all that
Is this the type of failure that should happen to this cool cat?
I don't think so, I'll see when I get there
I hope they're prepared for this video I share.
Well I pulled all the bolts and when I came out
There were chunks in my fluids in the pan and they drained out
I aint trying to get depressed cause I got all my spares out.
I sprang into action like lightning disassembled
I whistled while I worked and my hands never trembled
The 7-bolt was FRESH with the shine like a mirror
If anything I can say this bling was rare
What I saw inside the engine stained my underwear.
I turned off the air compressor 'bout 7 or 8
And I yelled to crankcase "Yo holmes, smell ya later"
I looked at my internals they were finally there
To sit on my workbench and stink up the air.
4g63 Balance Shaft Elimination - bearing modification
This is the first part of a two part series about balance shaft elimination
on 4g series engines. This video details the bearings, the other video
will cover the front case modifications. I've already got a low-def video
of the front case mods, and I plan to re-shoot that one in HD when I'm in
the assembly phase. It's linked in the video.
The balance shafts are designed to cancel out harmonic vibrations caused by
combustion and the spinning rotating assembly. They may offer a greater
degree of comfort to the driver and passengers, but with that comfort comes
Often, when a 4g63 timing belt gives up, it's because the balance shaft
belt breaks or comes loose and takes the timing belt out with it. When
that happens, it can total your pistons, valves, damage the crankshaft,
wrist pins, timing belt tensioner and crank angle sensor. Basically, it
can total your motor. The balance shafts also have a combined weigh over
10 lbs and both are driven off the timing belt making them additional and
heavy rotating mass. If you've got a lightweight flywheel but still have
balance shafts, you have your priorities mixed up.
So here's what you do with the bearings. It's easy. You can do this at
home. You CAN do it with the motor in the car, BUT DON'T. You must enjoy
punishment to do this like that.
The end result will slightly increase your oil pressure, but usually not
enough to cause concern unless you have a full-circumference bearing turbo, ball bearing turbo--with your oil feed coming off the oil
filter housing. The head feed would be better in that case because it's
regulated at 15 PSI.
How to build a 4g63 Coil On Plug Assembly
This is just like all other do it yourself projects.
1) Buy parts that make doing the job easiest for you. 2) Put the stuff
together. 3) Install it.
No really, I used the JMFabrications Coil Plate, ordered all new UF269
Chrysler coils and wiring from Toyota. This video is intended to
compliment thread #290665 at DSMTuners dot com which contains wiring
diagrams and part numbers for these specific products.
The only thing I did different was use 3/16" grommets in the harness holes
rather than elongating them to prevent wire chaffing. I went a little
overboard with the convoluted tubing, but it looks fantastic.
you can get coils from Chrysler models...

What isn't covered in that thread is the necessity of a capacitive
discharge system. In order for this to be any kind of upgrade a CDI is
required. The factory coil pack on these cars is good for 30+ PSI.
My Galant and the process of rebuilding its engine
Danny's 4G63 Engine Build Part 3
Finished up the rotating assembly today. Pistons rings installed, and Rods
are torqued down to the crank now. Next up is bolt on stuff.
Piston Wiggle in my DSM
So im going to guess that whoever put this engine together had no idea what
they were doing. All four pistons have a wiggle to them. You can almost
tell in the videos that the gap is too big. Almost as if they were the
wrong bore or something. Oh well, out with the old and in with a fresh 6
6 bolt 4g63 in 2g Eclipse GSX cylinder head removed in under 10 mins
Removing the head of a 4G63 in 10x speed.
The project got delayed a few months. After finishing it and cranking it
over, Interference in the cylinder was discovered. Shamefully, I admit my
mistakes were: 1) Not putting the spark plugs in immediately after
installing the head. 2) The bad habit of using my Valve Cover as a parts
tray and 3) Putting off the project too long, so I didn't recognize a
missing bolt from a custom fabrication.
The head needed new valve seats, valves and some welding. Wiseco and the
machinist both thought I'd be OK running the piston after smoothing out hot
spots, but I ordered a new piston not wanting to risk the deep gouge in it
with the high Boost I plan to run.
Peace of mind is priceless.
The danger in being over confident is sometimes you skip triple checking
stuff. I've built that engine at least 5 times and got careless.

4g64 DOHC Build-up
Here's a short video of my 4g64 with 4g63 head Build-up.
I still need to tune the motor a little as you can see or hear in the
video, the motor sounds a little rich specially after 7000 rpms. Dyno video coming soon... Hope
you liked it..
2g 7-bolt 4g63 Engine Removal & Disassembly
Tearing down the GSX to see what broke, and what I need to buy. Sitting
for a year and letting the battery drain took a toll on the polished
finish... and it looks like a piece of 4th gear wanted to take a look at
the outside world. Holy transmission case, and it's off to TRE to see
what's salvageable. Looks like the clutch could stand to be replaced, too.
Timing belt has taken some abuse from the higher rev limit and I was
expecting that. EGT probe is fried and I don't even care. Since I'm
running DSMlink and can log Boost,
I'm removing all my gauges anyway. Front case seal (freeze plug) is
leaking a tad, and the crank seal shows signs of excessive crankcase
pressure. I'm going to make some changes... I've got a lot of other
tricks up my sleeve, so stay tuned.

Basic Engine Building DVD - Chapter 25: Cylinder Block
By this time your block is disassembled and in the machine shop. One of the
most informative sections, here we take you behind the scenes to show what
goes on while your away. We show the process of align honing the main
bearing bore that is needed before anything else can be machined. Then the
block deck is leveled and machined as needed for the new head gaskets to
seat properly. And finally the cylinder walls are bored out just shy of
their new size, which will be achieved when they're honed.
BoxWrench.net is a community and resource designed for automotive
enthusiasts. The Basic Engine Building DVD is over three hours of engine
building that covers everything from removal and disassembly to final
assembly and engine start-up. This is the ultimate DVD for any home
