(NOTE: A lot of this information is covered in the FSM. You can download the CA18DET FSM here and check out the engine mechanical section. Background Replacing the timing belt on the CA18DET is a simple, though somewhat labor intensive task that can trip up new owners of the CA18DET. This guide will explain the process as well as a couple of shortcuts that will demystify the timing belt for new...
Related Links Project 240sx Overhaul Journal Index Day 26 and there are a lot of miscellaneous things creeping up. First, I am making a few changes to the oil system in the cylinder head of the CA18DET. Below are a few random pics and I will follow this up with a full guide that explains the method and reason to add this feature the CA18DET. (I am swamped right now so expect to see this in 2 to 3...
Related Links Project 240sx Overhaul Journal Index Day 25: I used my new powder coating gun to powder coat the valve covers, front engine cover and the thermostat housing. Also, new hard lines have been run from the 2 valve cover vents to a common T which will then route to an oil catch can. Smaller lines are used on the vents as I will be adding a rear oil drain to the head which will reduce the...
Related Links Project 240sx Overhaul Journal Index I had a change of heart on the exhaust routing and fabricated a new downpipe/uppipe that utilizes the RSR exhaust. The exhaust now routes along the stock path and retains the high flow catco 3in catalyst. 2-1/2in pipe runs from the turbo a 3in section where the exhaust and wastegate gasses merge. This should help quite things down and flow...

Background I stumbled across this oil cooler while scavenging a local salvage yard for Ford EDIS parts for a megasquirt install. This particular cooler comes as factory equipment on UK market CA18DET’s. As with most things Nissan, there are a lot of interchangeable parts and it just so happens that I found one of these oil coolers bolted to a late 80’s Nissan Maxima. (I forgot to...

The charge pipe has been painted to prevent corrosion and the BOV has been recirculated to the new air intake that draws air from outside the engine bay. Also, the valve cover vents have been rerouted to the new oil catch can and a Nissan UK oil cooler has been added to the block. I found it as the...
