Project 240sx Overhaul Journal (Day 17)

Related Links Project 240sx Overhaul Journal Index Today I retrofitted a marine type oil cooler onto the CA18DET.  This type of cooler transfers heat from the oil to the coolant system by installing inline of the cold outlet line on the radiator.  Since my car has more than enough cooling with a colder thermostat and the koyo radiator, this system should work really well in keeping the oil...

Related Links Project 240sx Overhaul Journal Index Today a new battery box was fabbed. I originally placed it on the frame rail but the clearances were a little too tight. It was relocated to the factory position. I also made a new mounting bracket for the liquid intercooler and went ahead and plumbed the heat exchanger back it. I plan on running this system for intercooling until I get the water...

With the engine reinstalled, I reinstalled the intake manifold and accessories as well as the wiring harness. A new radiator complete with an internal oil cooler was also thrown in for good measure.

This one took a little bit of doing but the rear sheetmetal was cut out of the trunk to make room for an aluminum fuel cell.

In addition to the new tension rods, new adjustable tie rod ends were installed on the front as well as Tein pillow ball mounts. The new tie rod ends are of the self lubricating pillow ball variety and should never need replacement. The Tein pillow ball...

I am beginning to focus on a little bit more weight reduction on the 240sx and the vented power steering delete kit works so well on the MR2 Spyder, I decided to make a kit for the 240sx.

I will post a clearer picture later but basically, this system uses gravity to maintain fluid in the rack while allowing excess pressure to escape.

A new battery tray has been installed as well. These are the new front and rear adjustable control arms. A custom mount was fabricated to relocate the battery closer to the chassis’ center of gravity. The rough cut of...

I finally finished my “little” test with the MR2 Spyder so back to the 240sx rebuild. Today I sanded, cleaned and rust proofed the steering rack. I also cut the power steering hard lines to make room for the new vented manual steering conversion.

I didn’t get a whole lot done per se but I did complete a major change to the rear suspension. The solid subframe bushings were installed and the subframe was reattached to the car. Of course, this entailed a significant amount of test fitting and adjusting as the bushings didn’t quite work in their unmodified form.

With the front and rear subframes removed, I went ahead and cleaned the members and then applied a rust converter / proofer. Once dry I added a base black coat and then gloss coat and then installed the new solid subframe bushings. A general “hardening” up of the chassis and suspension...

It’s been a few days but I finally had a few hours to work yesterday. I removed the factory bushings from the subframe and the diff and fully disassembled the rear suspension from the frame.
