Installing the larger KA24DE throttle body onto the CA18DET intake manifold is one of the rare free mods that has no drawbacks. Although a gain in horsepower is usually not evident when swapping a larger throttle body onto a pressurized (turbo charged) intake manifold, increasing the size of the...
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...
Become a friend of driftopia. Find out how here November 25, 2007 A new quick link has been added to centralize the data pertaining to the water injection install on the CA18DET. CA18DET Water/Methanol Injection Links. As progress continues, I will add more links to this page including a full water...
This page highlights the progression of the CA18DET swapped 240sx’s water/methanol injection install. Future tutorials will be appended when the project is complete. Images are from newest to oldest. To view the pics in order, start at the bottom. This image is here to show what the...
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...
New to 240’s and trying to figure out why no one actually refers to their car as a 240sx. This list should help you out. S13 = 1989 – 1994 240sx (Available as Hatchback or Coupe) S14 = 1994 – 1998 (Coupe only) S15 = 1999 – 2002 (Never sold in the US) And a few more terms...
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. Albeit, that is often a double edged sword for I have to...
Update: Colin McRae Tribute page is up. I felt like I had to write something for someone that has inspired my passions so much. You will be missed. Sept 27, 2007 New tech article up … HKS SSQV Recirculated Blow Off Valve Theory and Install. This article is not only specific to the ca18det...
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...
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...
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...
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...
