Hockey Puck Motor Mounts

I’ve come to the conclusion that the Nismo mounts that everyone swaps into their 240’s are not only over-rated but a waste of money. One of the main reasons people swapping in the CA18DET have a hard time locating a front strut tower bar that clears the intake manifold is due to the fact that the Nismo mounts raise the height of the motor. In my case, this problem was compounded when...

Clocking the SR T25 Turbo

The turbo found on the SR20DET motor is an upgrade that virtually every CA18DET owner has run at one point or another. Where the CA18DET T25 turbo is good to about 12psi and looses boost towards redline, the SR20DET T25 can run around 14psi and will hold steady till redline with the .80 exhaust housing. Additionally, there are tons of SR guys swapping out their factory turbo so finding SR...

CA18DET Vacuum, Boost, Water and Oil Routing Reference

Like most Nissan motors, the CA18DET has a maze of vacuum lines that quickly become confusing to those unfamiliar with the motor. The following is a quick guide of what needs to be hooked up and where in order to get your CA18DET up running. Upper Intake Manifold (rear) Read below for the explanations and click here for a larger view. Connects to the passenger side valve cover at the front of the...

Lightweight Aluminum One-Piece Driveshaft Install on S13 240sx

Installing a lightweight single piece driveshaft on the 240sx offers a few benefits over the factory 2 piece unit. First, your driveshaft is considered a rotating mass and as such, any weight saved on your driveshaft translates into a quicker, freer revving motor. This effect is similar to installing a lightweight flywheel on your car. Second, the single piece design of an aftermarket driveshaft...

Installing a SR20DET Lightweight Flywheel and Clutch into the CA18DET.

Background Even with the abundance of OEM parts available for the CA18DET, there seems to be a very striking lack of affordable lightweight flywheels. Clutchmasters and Spec make several clutch kits for this motor but for the time being there really isn’t a true, US market, bolt in replacement flywheel. Of course, there is always the occasional JUN lightweight flywheels that pops up on ebay...

Walbro 255lph Fuel Pump Install (s13 240sx)

The Walbro 255lph fuel pump is a must for any heavily modified and/or swapped 240sx. They are inexpensive, reliable and flow more than enough fuel to satisfy the thirsts of even heavily boosted motors. Note: These procedures should be performed in a well ventilated area away from open ignition sources. (i.e. gas fumes are harmful to breath and they can ignite) Depressurize the factory pump First...

DC Header Install

The KA24DE motor found in the US market 240sx is not the most powerful motor in the Nissan parts bin, however, with a few bolt-ons this motor can really come alive in its Naturally Aspirated form. One such bolt-on is the DC 4 into 1 header that yields a claimed 12hp over the stock header. Set up As with most installs, the car should be parked on a level, clean surface with the parking brake...

Compression Test

Performing a compression test on a running motor can give you a wealth of knowledge about the engine. For instance, numbers too low may indicate a bad head gasket, likewise a large variance in numbers can help you isolate problems down to the cylinder. Most importantly, compression testing is perhaps the single most valuable tool when purchasing a used car. Note: This tutorial highlights a...

Tein Basic Coilover Install

Although I have seen people do this procedure using just a tire jack, I generally think that is a bad idea. To replace your shocks, do it the right way and put your car on a lift or place your car on jack stands. Furthermore, all 4 wheels will be removed during this install so go ahead and loosen (not remove) the lug nuts at each wheel so that the wheels can be easily removed once the car is...

240sx Subframe Spacer Install

Installing subframe spacers is an easy mod that will eliminate the wheel hop present in the 240sx. However, it is necessary to place your car on jack stands before beginning. Furthermore, you will need to loosen, but not remove the lug nuts on your rear wheels before lifting as these wheels will be removed once the car is in the air. There are several companies making subframe spacers for the...

Whiteline Adjustable Rear Sway Bar Install

Replacing the rear sway bar can be performed with the car parked on a level surface with the parking brake applied. However, it is a much quicker and easier install with the car lifted so I recommend placing your car on jack stands. Removing the factory sway bar Locate the stock sway bar’s connecting rods on the lower suspension arms and completely loosen them from the arm by removing the...

Whiteline Adjustable Front Sway Bar Install

Replacing the front sway bar can be performed with the car parked on a level surface with the parking brake applied. However, it is a much quicker and easier install with the car lifted so I recommend placing your car on jack stands. Remove the factory sway bar The factory sway bar (stabilizer) is connected to the suspension at the tension rod brackets and the control arm (transverse link...
