$600 worth of glee

September 13th, 2008 drummingpariah

I searched around on Craigslist for a bit today and found a few deals that I decided to jump upon.  First up is a freshly tuned ZC package for $600, pictured to the right.  It came with the following goodies:

  • front crossmember
  • DC sport ceramic header
  • shift linkage
  • new axles
  • Si transmission + intermediate shaft
  • AEM ram air intake
  • motor mounts (with polyurethane inserts)
  • virgin pm6 ecu (now I have two, I suppose I could tune one specifically for smogging)
  • tuned (fuel map and raised redline) pm6 which probably won’t tune worth dirt

24 Hours of Lemons

September 8th, 2008 drummingpariah

If you haven’t already heard of it, the 24 hours of lemons race is a parody of the 24 Hours of Le Mans race.  I have decided to participate next year, and will most likely be sporting a 2nd-gen CRX.  I need an inexpensive 2nd-gen CRX though (something under $500 total).

The basic rules I have to abide by are:

  1. The cost of the car combined with the cost of parts to get the car running and racing cannot exceed $500 (not including safety gear like seats, roll cage, and safety harnesses).  That means getting receipts,
  2. The car that “wins” the “People’s Curse” award gets their car crushed halfway through the race.  Congratulations.
  3. The car must survive all 13 hours of racing (it’s over a course of 24 hours).  If it doesn’t, you’d better hope that some other kind driver is willing to push you the last few laps.

Now, the search begins for a damaged (salvage, possibly damaged frame) CRX that comes with an engine or two for under $500. Since I can recoup initial costs by selling parts from the car, I’ll probably be selling the fenders and interior. Read the rest of this entry »

B18a1 CRX vacuum diagram

July 25th, 2008 the Mad Scientist

At long last, the b18a1 -> CRX vacuum diagram is here!  This version may be difficult to read (it’s a draft, and I took the picture with my cellphone) but please bear with me.

This is a diagram on how to hook up the b18a1 vac lines using the stock CRX map sensor cluster (mounted to the firewall). If there are any questions/comments for future revisions, leave a comment!

Bitch Pin

March 3rd, 2008 the Mad Scientist

Tales are told around the campfire on moonless nights about the dreaded bitch pin. If you haven’t heard of this terrible monster before, gather ’round and I’ll tell you about it.

There will come a day when you find that your engine must come out of your car, and while your breaker bar will get those motor mounts, and your old rotting rubber hoses can be cut and replaced, the bitch pin is there to stay. Every swap is fraught with danger, but none so great as the bitch pin. It’s an impossible hydra-like beast, meaning every time you hit it it gets stronger and embeds itself further. You may find that perfect punch and a big mini-sledge, but the bitch pin still refuses to move. Never fear, though! This bitch pin has a great weakness to be exploited.

After I had already screwed my bitch pin into a pulp of metal that refused  to move, I looked around on the internet to find that everybody else just whacked it with a hammer. Eventually it’ll come out, right?

Wrong. Actually, using physics for dynamic force and using only enough pressure to move it is the key. Experimenting with a c-clamp and a wooden dowel yielded positive results, but I came across a better way. This article gives nice pictures and a good walkthrough of what needs to be done:

bitch pin removal

Add this “bitch pin removal kit” to the budget of any swap you tackle.

  1. C-clamp
  2. sockets (deep and shallow) that fit the bitch pin inside
  3. small drill bit set (for putting pressure on the bitch pin itself)

There’s definitely a science to it, but hopefully this will help you work that thing out.

b18a1 swap

December 14th, 2007 the Mad Scientist


Some of you may have followed my thread on SHO regarding the long and laborious swap that was supposed to be the “easy” b-series swap. Since hindsight is 20/20, I’m going to offer this post as a writeup to prevent others from running into the same problems I did. You’re all big kids, I’m sure you can come up with your own original problems on your own. No need to repeat mine.

Here are my personal recommendations to anybody planning to go from this:

to this:

in their CRX.
