Slowly working on my K24a3 drivetrain conversion. Car is a 1987 Bertone X1/9. Just finished up the wide body conversion this past summer, so now I'm ready to chop up the engine bay :D.











This has been done before, so there is a subframe kit which includes mounts, custom axles, shifter & cables.

Motor & trans came from a JDM importer in CA. 2005 TSX, 65K drivetrain.



Kit is designed for K20A2, so I had to swap the shifter module, right inner axle, oil pump/baffle/pan for >'04 RSX style.







Using K-Tuner modded '04 accord (drive by cable) ECU.

The cooling system, intake & exhaust need to be modded to fit the chassis. T/stat is Volvo C30.

made a custom adaptor to mate that to the bracket & stock pipes





RBB Intake cut & wrapped under the runners. Intake sits up against firewall, so stock (PRB, etc) runners are not user-friendly.




Built a header using 2" SS mandrel bends. Chopped the flange off the stock header. Length is dictated by chassis space.



Cone engineering collector & cone



Collector can't be welded until I can situate the motor in the chassis.



Chopped ends off stock cables & welded 10-32 ends to fit the custom shifter
cables



Bracket I made to hold the shifter cable bracket in the required orientation







Should be starting on the frame cutting this spring, after I do the AWD conversion on my Volvo C30T5

What a great project! We had an H series powered X1/9 locally that dominated the drag scene a few years ago. Awesome little cars.

Keep up the good work!

Slow going at the moment. Too cold to do much outside.

Figuring out changes to the AC system. Converting from VIR to orifice tube/ accumulator setup



Accumulator positioning options



Making brackets to set the compressor up top. No way to set it down in the factory Honda setup



Will be similar to this when in the bay:

Still a long way off from install. Made a sheet metal brake some time back in order to fabricate the frame insert panels required for the K24 subframe kit.



MFactory LSD going in. Ring gear bolts were not left hand thread.



SNap ring located



All back together



Had to get the block bored & honed due to rust in #4 bore.



NPR 87.5 RL5 pistons going in



King rod bearings



K24 balance shaft oil feed plugged



Blox oil pan baffle



Waiting for my modified VTEC gear to come back from the machine shop before I finish assembly of the motor - getting hub machined for an additional 5º total advance. Have the '07 TSX intake cam to go with it





Had trouble finding the correct water pump - turns out the JDM K24a3 uses the same pump as later Civic/CSX
