News, August 2007

August 23, 2007 Just thought I would add a quick pic of the front mount intercooler piping on the ca18det and let you guys know that the gallery is going to be removed for the time being as it runs way too slow on the current server. Also, we’ve got a myspace now so if you have one drop by. (link) August 17, 2007 The first S2000 install guide is now up. (T1R X-Brace Installation (Honda...

Contradictologists Stroking their Egorections

I don’t have a Ph.D. so I lack the credentials to make up words but even so this ridiculous topic requires just that special kind of phrase that can only be used to describe that special kind of internet Nazi, the contradictologist. The controdictologist is the guy that we all love to hate. He’s the guy that lurks around any technical discussion and only chimes in when he can catch...

T1R X-Brace Installation (Honda S2000)

The T1R X-brace is a strut tower brace that has a lower x member that ties the tops of the strut towers to the steering rack on the Honda S2000. This brace effectively locks the front of the chassis which sharpens steering response and feedback. Installation First, park the car on level ground, raise the hood and remove the intake box by removing the bolts and clips around it’s base. Now...

Part 1: Introducing the Honda S2000 Drift Car

Now why would you take one of the best handling production cars ever made and make it slide? I have found myself asking that question lately. Maybe it is because I like a challenge, maybe it is because I will try to drift anything or maybe it is because this is my brother’s car and like me, he loves all motorsports but drifting seems to hold that special place above all of the rest...

Part 6: And I Won’t Call It Drivetrain Tech … (part 1)

Ok, maybe I will but in any serious car buildup the obligatory drivetrain tech installment invariably comes up. And that my friends is what we are about to embark on. The drivetrain includes any system that takes rotation from the motor and translates that movement to the wheels. In this case, I will talk about the flywheel and the driveshaft. Any amount of weight that is removed from the...

June – July 2007

July 27, 2007 To answer the question of the hour, I added a general guide to liquid intercooling to the tech section. July 25 2007 Let’s see … it’s been a while because … I was on a business trip … oh yeah and it was in Hawaii. But I can’t say it was all work and now that I am back in town I will be reorganizing the site slightly and reopening the forums. I...

Liquid Intercooling

Of all of the mods I have done to the 240sx, liquid intercooling is the one that raises the most eyebrows, receives the most praise and insults and generally leaves people scratching their heads. This tech article is going to walk through the thought process and design considerations involved in liquid intercooling your Nissan 240sx. This is not a step by step walk but more along the lines of a...

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.

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...
