I'm reviewing an ebay 20g TD05 internally-gated turbocharger. You've seen me open it, assess it, and port it. Now I'm going to install it and see how it fits on my car. Its dimensions are close enough to a Mitsubishi turbo that it fits well, but it didn't play nice with my aftermarket stuff as the video illustrates.
You'll see what I mean...
The wastegate actuator nipple aims straight toward the compressor housing, and I don't like it. I fixed it with a pair of pliers and an allen wrench at 5:55 in a way that's far less likely to break it. The flanges and bolt centers lined up fine and without any issues, though others have claimed to have had them with this turbo. The compressor cover is an obvious giveaway regarding identifying this turbo. It does not wear the cast-in designation TD05H that the Mitsubishi turbos do, but for $228, what do you expect?
If you chose to go this route, just manage your expectations. Be aware that it might not bolt up perfectly to your particular car, and be willing to fix what isn't perfect.
First ebay 20g drag passes
I made 2 passes. On the first one, nearly everything that could go wrong
did. But I'm a persistent bastard. I fixed it all, found everybody and then
made this run. It wasn't until after I got home that I realized I had no
in-car video footage of the first run when I broke despite having set it
up... I kicked the alternator belt off no-lift-to-shifting into 4th gear
around 800 feet and coasted to a 13.3 at 82mph against a 10 second Mustang. Overheating with no power
steering I limped it back and put the belt back on, only burning myself 9
times, and then got back out and made this run. The guys in front of us
broke, too. I guess it was contagious? This run is on 93 octane pump
gas. I shouldn't have been in such a hurry. It left me a little
unprepared. You learn things about other things while doing things--is the
best I can explain it. It didn't knock at all, so clearly the new injectors
are working fine... but I didn't take time to burp the coolant system, so
it ran hot. My alternator belt was loose, and it bailed on me. I was
focusing on explaining the video (I deleted that scene from frustration)
rather than putting the car back together, and failed to plug in a very
important sensor. I would have caught it, but didn't get a chance to look
at the logs until I got home. I have to operate so many pieces of equipment
in addition to actually driving that it's very distracting. The guy in
my second race had a beautiful 1967 Dodge Dart, and he was a very good
sport! It was a great race where adrenaline is involved, and I was focused
but wary of whether or not the alternator belt would stay on. I really
appreciate the guys that keep old muscle alive. That car's almost 50 years
old. That's making history right there... He cut a great 60 foot after they
cleaned up the track, but I wish that car didn't break in his lane prior to
his pass if it was a problem for his run. I tried to leave nothing out
and keep it short & sweet. I was lucky to have a track-side cameraman for
the second race. Thanks Taylor! Having that sensor plugged in would have
left me much more confident in the log data and offer a much better
assessment of this turbo, but it is what
it is. Here it is...
More ebay 20g drag passes
Trolled by mother nature.
I thought plugging in my o2 sensor might make a difference. Scarily that's
not how things worked out. My fuel trims are all jacked up with or without
it. Airflow counts are down. I have more to do to this thing, but in an
effort to keep things real, I'm uploading what happened and what I found in
The PRIMARY reason for racing is development of both self and your
equipment. If your goal is to have an awesome street car, you can't
fully-achieve that goal without rigorous testing where numbers and facts
are clearly evident. You JUST CAN'T do that on the STREET. There are no
numbers on the street, no measurement of a baseline nor any improvements
you might make. There's no measurement of a drivers' skill outside of,
"did you win or didn't you?"
I didn't come to the track with the expectation of MY driving needing to be
improved. I was simply getting numbers, so I wasn't a tree-nazi like I was
in the Friday Night No-Lift-To-Shift video. There was more incentive for
me to just not red-light and see what she'll do.
This evening I didn't feel like the track crew were on their A-game.
Sometimes they held staged cars for an inordinately long period of time...
which once I'm staged, I'm on the rev limiter, and once they left me there
awaiting the tree for over 20 seconds, heating my car up and leaving me
disadvantaged out of the hole. Other times they treated the starting
lanes, dried off my opponent's side but not mine, not giving instruction to
hold or wait. In fact, one guy was signaling me forward while another crew
member was standing in front of my car spraying the lane. What do you
expect for only $15? I'm grateful for them, but the communication could
stand improvement over what I saw tonight.
Perhaps I'm just a bit miffed with my setup and looking for someone else to
blame? The track officials certainly don't deserve any for how it ran this
Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra
small-combustion-chamber head. Thats what it is. It's a J1 Elantra
cylinder head. Good luck finding another one like it. (read more)...
In Cylinder Head 106 I talked about the mainstream porting theories as they
are discussed. We looked at a cylinder head that I have thousands of
dollars of professional work performed on, and a bone-stock
second-generation head that I didn't port.
In this video I just might do something you haven't seen done before. For
some, that may be uncomfortable. The port and polish job I perform here is
what I think will work best for my current build. This is not an extreme
killer port job. What will be different here is where port textures are
concerned, I will be following the advice of a reputable source that will
remain un-named. You're free to port yours differently than I do in this
video, and I give you that out, around the 20 minute marker.
The Hyundai is far from being an ultimate-performance build. It's a $400
box of scraps with nothing but time invested. It's perfect for this video.
My finished product WILL be an improvement over what I had. I don't yet
have access to a flow bench. I still have an achievement to un-lock. As
far as you should be concerned with the techniques I employ... without flow
numbers there is no evidence of what this will do, but we will gather lots
of info from dynp sessions and drag strip time slips. If I could test it on
a flow bench, I would.
There are MANY, and when I say many, I mean thousands of flame war
mongering pirates floating around on rough seas with a hair trigger cannon
finger itching to fire if you port a head any differently than what the
herd mentality says to do while porting a cylinder head. I cover the herd
mentality because it has merit. It's been tested. Tried and true. But I
don't follow it to the letter of the law. I'm definitely not here to
de-bunk it. I would port a cylinder head differently for each build based
on how that engine was used. There's an extremely valid reason why
relating to air speed. It's not the texture of a port that maximizes the
effect of fuel atomization, but the velocity of the air running through an
x or y sized valve. The driving factor in this is the piston speed. I'm
not going to give you the technical information, but will refer you to
information about the Lovell factor. There's a better description of this
in the links below, and even a calculator to help you find your engine's
Why the Lovell factor is important:
Lovell gas factor calculator:
Only people who have flow testing equipment know for sure what really works
and have the capability to produce a perfectly-matched port job for the
ultimate performance build. Those guys know the definition of ultimate,
and THEY are floating below the water Aegis-class submarines ready to blow
your comment up if you don't know what you're talking about. They don't
care if you're an armchair mechanic or a herd of pirates. I will say,
they're zoomed in pretty close on me right now, and I'm expecting to take a
few hits. My work will be tested based on Dyno and drag strip performance,
and the results will be posted here. Fortunately, those kinds of videos
are a WHOLE LOT EASIER TO MAKE!!!
Ebay parts review (honda)
This is a review about ebay and their products, I ran a little about how
nobody wants to try anything but yet they want to knock it.. And for all
the haters there is something special at the end for y
Hyundai 4g63 Assembly Part 1
HOLD ON TIGHT! HERE WE GO!
We begin the blueprint and assembly on my 1992 Hyundai Elantra's
bastardized 4g63. The parts used in this are from a mash of different
brands and models outside of the typical 2.0L 4g63, but the specs and
standards I am following for its assembly are for the 2.0L DOHC.
If you want to follow along in your service manual to verify what I've done
here in this video, the processes we cover here detail pages 11C-95 through
11C-105 of the 1g Overhaul manual. I would prefer you not rip them from
the binding and throw them away, relying only on this video for
instruction... but rather use this video as a motivational guide, and as a
demonstration of the techniques involved in those sections.
You gotta do the cooking by the book.
I never had any intention of making instructional videos on this particular
car, but after it blew up I slowly realized it's actually a better case
study for how a 4g63 ticks than anything else in my driveway. There are
several reasons for this. One being that it's a mix of parts that
shouldn't be bolted together, and the other is that many of you watching my
videos aren't trying to build a 600hp engine out of aftermarket parts.
You're trying to put back together what used to be your daily driver. This
car covers those bases. Don't think for a second I won't go through this
same trouble and level of detail for the GSX. I will. When I do, having
this information in this video will give you a better understanding on how
and why I do things the way I do when I get there.
This was the shortest I could condense this video. I've never uploaded a
video this long, and I hope I never have to do it again. It took a month
to create on cutting-edge equipment, 16 hours to export, and 9 hours for
YouTube to process. My script for the voiceover is 6 times longer than the
whole script for the movie Pootie Tang. 6 times. Longer. Than a
Porting an eBay 20g turbocharger
The price of this turbo will make it a
popular purchase, so I figured I'd air out some tech about ways to improve
it. This thing is not for everybody. I wouldn't feel comfortable bolting
it on my car the way it comes out of the box. I could complain about its
flaws except that so far absolutely none of them have been a deal-breaker
for me. To me it's like an empty canvas. I promise to eat those words if
it happens, and share my poop. Usually I can easily correct these flaws
myself and so can you.
If this thing turns out to perform well with what I do to it... It could
easily be a cheap, quick ticket to an 11-second car. Something you could
do with a free running 1g, a hacksaw, and about $500 worth of fuel
upgrades. Yeah, that would be ridiculous, and I'm bolting it onto a
well-modified car... But that being possible speaks volumes for what a DSM
can really do.
This is no big deal to me. I'd rather guinea pig my car for you in HD so
you guys can decide whether or not you'd spend your money on this. Really
it's an experiment because this isn't my daily-driver, and it contributes
to building a better Colt.
Tools I used involve:
Milwaukee model ???? 1/4" straight-shaft electric DIY grinder
Cone and ball-shaped double-cut burs
180 grit high-speed flap wheel
Dremel with a flex-shaft and a tiny 320-grit flap wheel
a zip tie
10mm combination wrench
tiny flat-blade screwdriver (00) for the e-clip on the wastegate
2g GSX How-To: Attempting turbo swap with WTF ending
Okay. Now I've seen it all. There's an old adage that states "if you want
something done right, you have to do it yourself". Well, this video both
confirms and debunks that theory. A lot of that depends on each person's
definition of "done right". You can't do things by-the-book with
Sheldon bought this car with a pretty full mod list and it ran great at the
time, but by the time we got it to the track, we couldn't beat a 16-second
pass. Despite the laundry list of troubleshooting we both attempted to do
through tuning and testing, we couldn't determine why it was around 4
seconds slower than it should be running. I started having doubts that a
"ported T-28" was what was on the car, and there's no easy way to tell them
apart without removing it so we opted to install a 14b... since plenty of
people easily run 13's with them. Stick around for the plot twist.
CRANKWALKED? 7-bolt teardown 1080HD
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,
'n 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 all depressed cause I seen this before.
I got my books and my wrench and we'll do it once more.
I sprang into action like lightning disassembled
I whistled while I worked and my hands never trembled
If anything you could say that this bling is rare,
and when I saw what broke I 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.
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.
Turbo Elantra Bearing Failure Diagnosis
I had time to look at this thing up close. Go through the oil system, and
check out all the bearings. Looks like another good study for my oil
system series because it's the opposite problem that my GSX experienced.
High oil pressure can be remedied a number of ways, but left unchecked can
actually take a toll on your bearings. The way your engine bearings work,
the parts they suspend are supported only by an oil film layer, and flow
needs to be right in order for it to work as an actual bearing. If the oil
supply is insufficient, then it loses the ability to suspend the part
causing it to crash into the bearing surface. If oil flow is too great,
friction is increased, the flow becomes turbulent, and the oil film doesn't
form properly. High oil pressure can float and spin rod bearings, and
that's worst-case scenario.
I had several un-favorable conditions going on inside this engine and that
makes it a little bit difficult to link what my engine experienced to any
one singular thing. I think it's easier to look at it like some sort of
From sub-standard parts for how the engine components would be used, to oil
pressure, to part fatigue, to part history to abuse... this thing's got a
little bit of everything working against it and that's why it's such a
hilarious car. It was given to me with one condition. "See what this
thing will do, and see how long it goes before it breaks." My take on it
is, the parts are still less than ideal, and they've still got life left in
them. It's worth fixing. These parts are worthless as a race motor, and
normally I'd have junked 'em, but it's the Hyundai.
Boost Leak Testing 202: Hair Spray 1080HD
Why do I know about this?
I'm tired of being the one knowing all the weird crap. If everyone knows
it, it won't be weird anymore. It will be commonplace. By the time I'm
done sealing up all of my own Boost
leaks, all of you will also be experts as well. I'm sure most of you would
teach me something, too... but you subscribed, so here it comes...
something I learned in my travels...
Also, thanks Ilya M. I've only heard about it twice in my life. It worked
great for the one time I've ever needed it, and I'm a huge fan.
4g63 Block Cleanup & Oil System Mods
With no data other than another person's testimony and from observing the
condition of failed rod bearings I was able to determine this engine
suffered problems from high oil pressure. There are 3 modifications that
wanted to perform to its oil system, and 2 parts I chose to replace. All
of the videos that go into greater detail about these modifications and
parts are linked from this video. Though I've covered these topics, this
is a video of the work being done to the Hyundai because it's part of its
Also in the process I've stripped and removed all gaskets in preparation
for parts washing. All of these tasks can be completed without an air
compressor by taking your time with a razor blade or using electric
grinding tools. If you're doing this kind of work, I strongly suggest for
time's sake that you use an air compressor. If you have access to an air
compressor and any of these [cheap] tools, then you can do these kinds of
modifications for less than $20. NAPA sells everything but the spudger
(below) individually so there's no need to buy these consumable supplies in
3m bristle discs:
I used this cleaning up the oil pan. It's a spudger. An electronics tool.
I also used 3m Scotch Brite wheels to clean the oil pan's gasket surface.
"Fix" J-pipe for ebay 20g
HI KIDS!!!!! Here's what I did to make the 20g work with all my
aftermarket stuff. All I had to modify was the J-pipe. No aftermarket
pipes would work because they wouldn't point towards my lower Intercooler pipe. This car is equipped
with a short-route pipe kit with an unusual set of custom pipes. You'll
see how to mark a piece to be welded, and you'll need to be resourceful if
you don't have a welder that works on what your pipes are made out of.
This thing fits perfectly now. This leaves me unable to really blame the
turbo for the fit because this J-pipe's
always been a bastard.
I need a TIG welder BAD! Thanks Ronnie! This was 50¢ holding up a
dollar, and I appreciate the skill. ...and THANKS AGAIN RojoDelChocolate!
How to Rebuild a Turbo - Part 1 of 2
Rebuilding a td05h 16g turbo. This
process can be applied to many journal bearing turbochargers. :) It definitely comes in handy to
know how to do this when you are in this type of hobby.
4/25/12: Small explanation on the balancing of the rotating assembly since
I get so many comments regarding it. This particular turbocharger, td05h, has its rotating assembly
components balanced separately. This means each individual part (compressor
wheel, turbine wheel/shaft) gets balanced separately. This allows for easy
interchangeability of parts in case they need replacing. This is why I am
able to install a td05 20g wheel on this turbo without having to balance the entire
rotating assembly. THIS IS NOT THE CASE FOR ALL turboS OUT THERE. You need to research whether
your specific turbo (if it's not td05h)
was balanced as an assembly or "component balanced" like I explained above.
I hope this information helps. Good luck in your projects. Stay Boostin'
