Summary of various D14A3 / A4 / Z1 / Z2 engines with modifications

 

Polivios

Between the first time this page was launched and now, various other people have accomplished similar IM swaps and this one, from a Greek D14A4 driver named Polivios, is really worth posting. This is accomplished with a very nice aftermarket intake which seems to run very well. Here are the specs, a photo and a certain dyno result (though Polivios and I are certain it scores 4bhp better after a little SAFC). His results are even better than mine after the OBD1 swap, mainly due to his better hardware I figure.

 

Specs:

-Honda Civic 1.4 EJ9 sedan D14A4

-118bhp@6500rpm

-137Nm@5400rpm

 

-Simota air Induction Kit

-60 mm intake tube

-Denso iridium power sparks

-5star 9.5 mm ignition cables

-"sport-spec" valve timing adjustment

-Custom cat-back exhaust 50 mm Danelatos

-Dc Sports 4-1 ceramic coated exhaust manifold

-Sebring high flow cat

-3-wire O2 sensor

-JG Edelbrock IM

-APEXi VAFC2

Very nice going!

 

Sebastix

Sebastix is the first person I know of who did the D16Y8 IM swap on the D14Z1 version of the EJ9 Civics. Check out his website at http://civic.sebastix.nl. My guess is that he will supersede this result soon enough…

 

Specs:

-Honda Civic 1.4 EJ9 hatchback D14Z1

-123.6bhp@6968rpm

-141Nm@5700rpm

 

-OEM D16Y8 IM

-DCSports 4-2-1 header

-Nvidia cat replacement

-OEM EK9 muffler

-OBD1 ECU with Crome

Dodo Bizar (that’s me)

In December 2004 I did the first IM swap known to me on a D14A3 EJ9 Hatchback Civic. In the summer of 2005 I also did the OBD1 swap using Crome putting out 116bhp. In December 2005 I also did the first VTEC head swap on this type of car in my believe resulting in 133bhp. Later on I used eCtune and got 136.6bhp. A Skunk2 TB and IM gave me again 137bhp while the cat converter was in place. Both VTEC results are presented here. In the meantime I have installed a Skunk2 Stage 1 cam, valve springs and retainers. This did bring me over the 100bhp/litre threshold in January 2008.

 

Specs:

-Honda Civic 1.4 EJ9 hatchback D14A3

-145.1bhp@7478rpm

-150Nm@6000rpm

 

-Simota air Induction Kit with K&N 8” filter

-70 mm intake tube

-Skunk2 70 mm throttle body

-Skunk2 intake manifold with 240 cc injectors

-Hondata heat shield

-D16Y8 head

-JCP 4-2-1 header

-Megan cat replacement
