over hang from installation and correcting the combustion chambers to
unshroud the spark plug is a big deal on these heads. China castings leave
a lot to be desired, but still with all the work you must do it is still
the bargin of the year and is a force to be reckond with when "bang per
buck" is needed. The base of the spark plug should not be exposed in the
chamber, and any valve guide "Overhang" will obstruck flow and create fuel
"sheer" which seperates vapor to droplets that wont burn. Most Big Name
companies will not take time to detial these issues as production cost
prohibit these mods, so have your local machine shop take apart your heads
and look for these problems before you bolt them on your prize engine.
Volvo Engine head porting / port matching prep work !
Music : Mr oizo and Gaspard Augé "tricyle express"
Step two in the project :
Gasket matching is a good way to improve the flow in your head (engine
heads only) and to avoid the bad turbulences where they are not supposed to
be : between parts.
It's the first step in your porting job that you should think about ,and do
with your brain and hands.
The castings patterns are often quite "bad quality" (or i should say the
consequence of the application of a mass production process ) and it's the
way to start this kind of job.
Cylinder Head 106 - Casting & Porting Tech
No really guys, what can I type here? I just went on for 18 minutes
without shutting up. I apologize for deviating from my normal format, but
we're almost there...

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

tiny flat-blade screwdriver (00) for the e-clip on the wastegate

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 it's 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'
