HKS SSQV Recirculated Blow Off Valve (BOV) Theory and Install

BOV Theory Installing the SSQV BOV Theory The function of a blow off valve (BOV) is to reduce pressure waves that result when the throttle plate of your engine is suddenly closed. For example, when shifting gears the turbo is still pressurizing the intake piping but without a bov to release this building pressure and with the throttle closed, the air can surge backwards and over time damage the...

Aftermarket Lady Lumps

And no I am not talking about breast implants. What I want to know is do boobs make your car faster? Do they make you a better driver? Hell, I bet a purist would argue the converse and tell you that smaller is lighter and therefore better. Regardless, I received a flyer recently for a first annual drift and drag event sponsored by a local drift club and something caught my attention as slightly...

A Tribute to Colin McRae (1968 – 2007)

I am writing this now because in all honesty I didn’t know what to say when this first happened. No, I never had the honor of meeting Colin McRae but I remember staying glued to the TV for hours on end watching him fling the Subaru Impreza WRX rally car around countless rallys all throughout the world. McRae’s driving was literally supernatural and in fact, I can say that he is one of...

Nismo Adjustable Fuel Pressure Regulator (FPR)

A few months ago I posted a how to guide on installing a Walbro 255 fuel pump into the Nissan 240sx. As I noted the Walbro has a tendency to overflow the stock fuel pressure regulator on the 240sx and cause the injectors to operate at a higher fuel pressure which ultimately richens the fuel mixture. An overly rich fuel mixture harms gas mileage, robs horsepower and can even damage the motor. This...

Brake Bleeding (240sx S13)

Well I’ve got some advice for them, how will you ever learn to maintain your brakes if you don’t ever try. And honestly, what follows is a very easy walkthrough that will allow anyone to bleed their brakes...

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

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...
