Distributor & ECU:
Make sure you use an 86-87 Integra ECU & Distributor. That's
the only DOHC ECU (besides a JDM one) designed to work with a Vacuum
Advance Ignition (distributor) which only came on the 86-87 Integra's.
***Do not use an 88-89 Teg' ECU or Distributor**** Simply because
it has an internal coil ignition just like all the 88+ civic/CRX/Integra
use, which is completely different than the 86-87 ignition components.
Q: Can I put a fuel-injected engine into
a car that currently has a
carburetor?
A: Fuel injection requires a pressurized fuel system
that the carburetored cars do not have. You will need to change
the fuel system and a large portion of the wiring harness to put
a fuel injected engine in your car.
Q: Can I put a B series engine in my 1st
Gen CRX?
A: www.hasport.com
makes the kit to do it. Bring a bag of money.
Q: I want a more aggressive ECU (Computer)
or a chip and fuel injectors to increase performance in my Si.
A: As far as I know, no one makes a chip or a high
performance ECU for the 1st Gen CRX Si. The 1986-87 Integra ECU
and fuel injectors will plug right into your car. The Integra ECU
will let you rev higher and the injectors will flow more fuel. I
suggest that you also install a fuel pressure regulator, a fuel
pressure gauge, an air/fuel ration meter and a honed throttle body
for increased airflow to match the increased fuel flow.
Q: How can I make more power in my fuel-injected
engine?
A: If you get more air and fuel into the engine,
the engine will make more power. To supply the "more fuel" I put
in a set of 86-87 Integra injectors that I had cleaned and balanced.
To get the "more air" I built a better breathing throttle body out
of a stock, twin choke throttle body. I opened the throat of the
primary choke from 20mm to 26mm and I also smoothed the path to
both chokes. Using a Dremel with a cutting wheel I cut the "lip"
of the primary throat so that it was even with the "shelf" that
surrounds the primary throat. I then drilled down the primary throat
on a drill press and with a 61/64" drill bit. Finally, I cleaned
every thing up with a grinding bit on a 3/8" drill and a wire brush
on the same drill.
Q: I was thinking of installing an undersized
crank pulley.
A: Don't bother. I had one on my car and it did
nothing to improve performance, all they do is make your alternator
and A/C compressor spin slower. The stock crank pulley is designed
to work with your engine and should not be changed.
Q: My idle fluctuates up and own by a couple
hundred RPM on my fuel injected engine.
A: Your Throttle Position Sensor (TPS) has gone
bad. This is the portion of the throttle body that tells the ECU
how far open the choke plate is. Normally, if the TPS goes bad you
must replace the whole throttle body because the TPS is attached
with slot-less screws. But, you can cut slots into the TPS screws
with a file or a Dremel tool and unscrew the TPS. Swap in a junkyard
TPS and that should fix your problem.
