The best platform is the 16V for it's flow,
but the best crank is the double counterweight
16V crank also, not that the earlier crank is
bad, but double weights is a smoother runner.
The bottom ends are the same in all 1.6L engines.
Forged pistons are stronger, and have a different
expansion rate than cast pistons (stock)
If you are going to get forged pistons, get the
low compression ones, you get more HP from
a low compression turbo engine, stock is 9.1:1
ideal would be 7.5-8:1, you will be able to force
more air and higher boost, and get more power,
as well as the torque will still be there.
Stock fuel pump is good enough, stock TBI injector
is not, and there is no way you can flow enough
fuel with it, no matter what pressure. It takes 4 times
the pressure to double the flow of any injector.
The stock fuel PSI regulator is a 1:1 ratio (on TBI)
so it will boost the fuel PSI to match the turbo boost.
If you go with an 8V intake TBI, you will need 4 extra injectors to feed the engine under boost, about 25-30
PPH will work fine, I found 17 PPH with the stock TBI
just enough, but not enough to run rich under boost.
CZ, the hughes engine is better suited to a street
application, any time you go from 80 to 150 HP the
ports are going to be so opened up the air flow under
NA conditions are going to suck until high RPM, now
it you mellow out the cam, and lower the CR and add
a turbo or supercharger, that engine will act totally
different, you might even like it. The engine will be
a boost dependent engine, but with a small quick
spooling turbo, it would be a rice killer.
Humzuki, don't build a log manifold, it's not a great
design, it will work, but it's got some problems too,
one is the space and location of the turbo, and if you
have power steering, the turbo needs to be higher.
You can't get a bigger TBI injector, and it's not worth
the $$ when you can get nice injectors for $5-10 from
the wrecking yard, these would normaly cost $50-80
from a rice tuner shop Ford Turbo T-bird has 35 PPH
and 2.3L NA has 25 PPH, Mercuer (sp) XR4Ti has 35 PPH
MegaSquirt has an awsome how to assemble online manual, called the MegaManual, go thru assembly,
testing at the completion of the phases, so if somthing
is wrong, you find it at that stage and can check your
work, if you can read and follow directions, you can put
a MegaSquirt Together, the MegaManual also goes thru
tuning and setup to get you running fast, but you will
need a laptop for tuning, unless you want to put your
PC on the road with an invertor, get a cheap pentium
90 or 100 they work great for this application and should
be very cheap $$ (nobody wants them)
