Part 7: The Quest for Efficiency

If I were to ask you what your vices are, what would you say? Now what about your automotive vices? What preoccupies your mind when you are working on a project? What grabs a hold of you and makes you a slave to the build? I myself have a few and one such vice is efficiency. More specifically, I’m talking efficiency of design, efficiency of cost and efficiency of power. This latest...

CA18DET Coolant Mod Number 2 (From 10+ Lines to 1)

Depending on how you count it, the ca18det has over 10 coolant lines. For those building their cars for race use, this can be reduced to only one line (excluding the radiator inlet and outlet). I will demonstrate this with my own car, the ca18det swapped 240sx. In this tutorial, these 11 coolant connections will be reduced to the radiator inlet and outlet and then one coolant line to the rear of...

Archived News, October 2007, Driftopia.com

October 25, 2007 <begin evil genius laugh></end evil genius laugh> Ok sorry for that. A little programmer or dork humor if you will. Yeah, I’m a big dork but so what. I happen to also be a person that can’t stand the word no.

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...

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...
