Here is an outline of the Hasport engine swap into our 2001 Civic EX Sedan.
Although as we go through the process of writing the instruction for the
swap I may add to some of the details.

It is broken into three sections: parts list, engine install and electrical

01-03 Civic K20A installation outline

Parts needed:
K20A2 or K20A3 (from Civic Si) Engine w/ AC compressor, alternator, P/S pump
(if you want powersteering), wiring harness, exhaust manifold and catalytic
converter

ECU

Transmission and starter

intermediate shaft

Axles from either 02 Civic Si or 94 up Integra GSR (we used 02 RSX with RSX
knuckles and hubs)

RSX or 02 Civic Si subframe with lower control arms

Hasport ESK1 bolt in mount kit

RSX shifter assembly and cables

02 Civic Si radiator and fans (although the RSX will fit with some trimming
around the radiator cap opening in the grill)

02 Civic Si upper and lower radiator hoses (RSX are longer and may kink)

RSX high pressure powersteering hose and return line (if you want
powersteering)

92 Civic P/S resevoir w/ bracket and 90 Accord heater hose from head to
heater valve (if you want powersteering)

RSX throttle cable

RSX fuel line, brake booster line and purge line

RSX AC line from compressor to condensor

90 Accord negative battery cable

The installation (not including electrical)

After removing the old engine and subframe the Hasport left and right
brackets are bolted in place.

Next the RSX P/S hoses were installed. On the passenger side where brackets
are present on the RSX rack but not the Civic's we used heavy duty zip ties
to secure the hoses. We installed the 92 Civic P/S resevoir just in front of
the fuse box with a bracket we made to the 92 Civic's P/S resevoir bracket.
The return line had to be modified to fit.

The hood latch support was in the way of the Civic Si's radiator fan so it
was removed (cut out) and a new one was fabraciated from aluminum and bolted
into place.

The engine installation is pretty straight forward, the only gliitch is that
the passenger side mount is a little tricky if you are coming up from the
bottom with the engine. You need to lift the engine a little above it's
position at rest to install the mount. The subframe was installed at this
point.

The Civic Si or GSR axles go right into place with no modification.

The header and cat from the engine bolt right in place and use existing
hangers. If you are installing the 02 Civic Si engine with header and cat,
it will line up with the stock exhaust. If you are using the RSX engine and
its header and cat, the exhaust will need to modified. On our 4 door we
used Ractive's RSX cat-back system and had to lengthen the intermediate pipe
and tail pipe 3 inches each. I am not sure of the 2 doors dimensions and
what would need to be changed.

For AC, we had a custom AC hose from the compressor the the firewall
fabricated and used the RSX AC line from the compressor to the condensor.

Then the radiator w/ fans and hoses were installed.

The fuel line and purge line were then gently bent so that the RSX lines
could be hooked up.

Our car was an automatic, so we simply bolted in the RSX shifter mechanism
and hooked up the cables. Some wiring then had to be done to hook up the
park/nuetral safety switch to the clutch.

The electrical:

When you use the RSX harness (which is suggested) the Civic body harness
lacks these three items; air fuel ratio sensor (first O2 sensor), air fuel
ratio relay (except HX model) and radiator fan switch. We added these with
the engine out so that it was easier to get to everything. A Hasport
convesion harness will be available within a month or so for this. For those
who wish to do it yourself, just get an RSX or Civic Si manual or ETM and
figure it out. It is not too difficult.

The RSX harness on our engine was then modified so that the two heavy gage
wires that connect to the fuse box were moved to the side of the engine bay
as the Civics fuse box. The positive and negative cables then went to the
side of the engine that the RSX has it's battery. Temporarily we mounted the
battery on the subframe just in front of the tranny, but the new mount kit
will allow us to mount the battery higher near the RSX's battery location.

The RSX harness was fed through the firewall where the Civics harness goes.
Two plugs form the RSX harness connect directly to the ECU, but the third
plug connects to the body harness. Only a couple of these wires are in the
same location as on the Civic's harness. Because I lacked an RSX or Si ETM I
individually traced out the location of each wire. I should have kept
record, but I didn't, so after I get the proper manual, I will put together
a diagram. This is the part that will screw up most people, so that when
Hasport starts offering the conversion harnesses, we will make sure this is
taken care of.

Last, for driving the car over to Honda to get the RSX ECU flashed to accept
the Civics key code, you should be able to drive on the Civic ECU for a
short distance.


With our Civic we opted to use the RSX knuckles, hubs and brake assemblies,
so we also used the RSX axles. The RSX axles can be use with the smaller
Civic hubs if you change the outer joints to those of the GSR or Civic Si.

Our Civic was an auto, so some wiring then had to be done to hook up the
park/nuetral safety switch to the clutch pedal switch.

Hey I hope this sheds some light on what is involved in the swap. We will
have more pictures on our web site as we further modify the car. Also look
in the nesr future for the first K24 swap as we build a big block for our
Civic and soon we will be doing a K24A Accord engine and tranny swap into a
01 Civic.
