The Hibernation

After the second lemons race and the dispersion of interest in racing among the team, I satisfied my track interests and build interests with other projects. It was during this timeframe (2009, 2010) when I finished my LS13 (Ls1 swapped 240sx (s13) chassis). It became my HPDE weapon of choice, and I spent alot of time and cash on the car. In 2012/2013 I stopped spending money on the car and diverted that money into buying track time. Thanks to my father, we became VIR club members, so I had the opportunity of 14 track "weekends" per year at a reduced cost with low attendance. I cannot say enough about VIR club and the opportunites for learning and improvment it has provided us.

Much of the knowledge and information for the LS13 swap came from the following webpages:
Nissan Road Racing (suspension setup information - A generally smart and helpful group of guys)
Silvia V8 (Engine swap information)

The car is currently sitting, waiting on a roll cage, brakes, and a set of proper dampers before it gets back onto the track. It will ride again one day (soon).

I will be working on a excerpt of the build documentation for the 240sx here. I am attempting to recover the build thread from the now defunct If that is not possible, I will have to re-construct it from photographs and memories.

After the initial completion, and before the 2011 upgrades, I had the opportunity to weigh the car. 2750 Lbs (without me). Should be about 2700 in its current form with the weight reduction measures that were taken.


The first track-outing for the completed LS13 happened with Chin Motorsports in November 2009. The rain may have slowed the speeds, but it didn't dampen the fun. It was a good thing the rain came, because I drove it home with the e-brake after totally wasting the front pads that were on it. At this time, it was running 300zx front brakes, but I do not know what pads were used.

Major "recorded" issues

1. Brakes!!!
The brakes are all wrong. The pedal is very stiff, and there is no modulation (on/off switch). The bias is not correct F/R

Possible solutions:
      A. Master Cylinder Sizing - A smaller master will move less fluid and result in more pedal travel - aka more modulation. This is complicated by the off-the-shelf choices available from Nissan, and the built-in bias valve (For front/rear bias) in some. Available sizes: 7/8, 15/16, 1, 17/16. The 7/8 size is OE S13/S14 fitment, but includes a built in bias valve that is difficult to bypass.       B. Brake Caliper Sizing - Larger front brake caliper bores will acheive the same result.       C. Adjustable Bias Valve - This did not help the sensitivity / Lack of modulation. This did correct the bias - More front brakes could be dialed in after this was added and the factory bias valve was disabled/bypassed on the 15/16 master cylinder       D. ABS - This has not been installed yet but I have sourced and acquired the parts. A full S13 ABS removed from a junkyard car, including harness connector pigtails and the computer. This will provide confidence in the brakes by being able to just "mat" the pedal lap-after-lap without worrying about modulation.

2. Shocks
The shocks are cheap D2 chinese-tiwanese crap that I bought in highschool. $900 I paid... I regret that purchase to this day. I could write a book on how D2, Tein, BLITZ, etc are crappy suspension pieces. Mind blowing, I know... Being HELLAFLUSH isnt fast... its a lifestyle choice. I am not after HELLAFLUSH - so suspension travel is important. Maximize the grip available from the tires and track surface at any given point.
      Install actual Dampers, with correctly matched springs. This will be either a Koni or Bilstein offering, Likely Koni 8611's. It requires custom strut tubes to contain and mount the dampers. A source used to sell them from the northwest (from, but they were prohibitively expensive and his responsiveness and turnaround were less than stellar. I will need to fabricate my own and source a machine shop to thread them for the containment "nut".
      Ideally I would like to run standard 2.5 inch "Hypercoil" style roundy-round springs. They are cheap, readily available, and come in a multitude of different rates. I could play with the spring rate until I find the best combination.

3. Safety
The car is unsafe for the speeds it generates.
      1. Roll Cage. I have purchased the Tubing Bender and Die (1.75 inch, 5.5inch radius), the Welder (Miller 211), and the material (.120 1.75 DOM, .125 plate for baseplates) I need to make the time and generate the motivation to fabricate it.
      2. Seat. I need to purcase a actual race seat, like what is in my E30.
      3. Harnesses. It needs actual Harnesses. Seatbelts, attached to the roll cage. DUH.

Track Footage

Best recorded lap - Chasing an Ariel Atom (I can only keep up due to traffic)

Lap recorded using bumper-cam - interesting perspective of the "old" track surface. Kind of halarious that now I am running 2:22's with a 160hp E30.

Driver Failure here - The brakes have always been a sore subject with this car, and I have yet to get them where I want them. Here I am on two separate occasions over-driving into turn one and narrowly getting slowed up in time to avoid the tires.

Dash-cam footage from Driftwater 12 (grassroots open-track event held in Moyock NC) in 2011. Nothing spectacular happens, but there is a good 10 minute span of me chasing a miata.

Me trying out some Drifting at my second trip to Driftwater (Driftwater 14 in 2012). I'm obviously not very good at it - maybe I will stick to normal racing.
