Part 1: Introducing the Daily Driven, Grip Racing MR2 Spyder.

Introducing project MR2 Spyder (MR-S), my daily driver. I might as well come clean up front, I wouldn’t want you guys to think I am going soft, or crazy for that matter as the MR2 is not the best choice for a drift platform. It really is simple though, my passion for motorsports extends beyond the world of drifting. Not only do I love drifting, I enjoy auto-x, road racing, rally, time...

Custom Cold Air Intake (CAI) for the CA18DET

This tutorial covers the steps necessary to replace the factory flexible intake with a solid, metal pipe unit that will always draw ambient air from outside of the engine bay. This will ensure that the turbo is supplied with the coolest air possible and will provide a little less thermal load on the motor and its supporting systems. Additionally, running a custom hard pipe instead of the flexible...

Swapping the KA24DE Throttle Body onto the CA18DET Intake Manifold (The Quick and Dirty Way)

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 throttle body will improve the motor’s on/off throttle response as well as boost response. The...

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...

Driftopia.com, News Archive November 2007

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 injection install and a how water injection works guide. In the meantime, check out the first link...

CA18DET Water/Methanol Injection Progress Pics

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 compressor blades looked like before water injection. I’ve decided to use placement #4 from this...

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...

Deciphering 240sx lingo. (Chuki’s, Kouki’s, Silvia’s and Zenki’s Ohh My!)

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 (Silvia, Sileighty and 180sx) S13 = 1989 – 1994 240SX (Available as Hatchback or Coupe) A 1989 to...

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 learn everything the hard way but on the flip side, I have developed an impeccable bullshit detector as...

News, Sept 2007

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 swapped 240sx but is also a guide to installed a BOV in a MAF system. The SSQV BOV installed on the...

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...
