L28et Compression Test

Cleaning my Garage for spring cleaning and I found an old note for compression numbers on my L28et. I did the test because of the fuel issue I had, I thought it was a compression issue.

143-147 all around. Looks Great! I’m pretty sure my l28et was rebuilt at some point. The head was super clean when I installed it.

Also, The Z is looking stockish now adays.


Puerto Vallarta, MX spring trip

Last Month, my buddies an I decided to take a trip out to Mexico for vacation.  We had many places in mind but chose Puerto Vallarta as our destination (price point is muy bien!) as no one had been to MX before. We chose to stay at an all-inclusive hotel, which turned out to be a smart move considering the amount of drinks and food we consumed on this trip.

Aside from the spring break shenanigans, I was amazed by the public roads, traffic rules, and cars that made up the Mexican commuter lifestyle. Suprisingly, VW’s, dirt bikes and prerunner type trucks were everywhere. It reminded alot of Santa Cruz but with its own flavor and style.  I was stoked to get a headstart on summer and finally get out to a beach:

Its always a treat to see life from different perspectives. Salud!

Megasquirt P.2 (Fuel Surge Tank!)

Before I dyno’d the Z, I got it running on basic maps I found on the Hybridz forums. Idle checked out, warm-up checked out, and it pulled pretty good. But to my horror I had the same issue that I had before Megasquirt:once it heated up, the car would lose power on boost. My fuel pressure gauge was telling me that the pressure was dropping under boost so I upgraded the fpr to an Aeromotive adjustable fpr. My fuel pressure PSI was rock solid! at idle.. The new FPR made the pressure loss even more obvious. it had to be my pump. Which I had already noted was LOUUD. The old set up was a used walbro 255 is place of the stock fuel pump. Also note the Fram G3 Filter. DONT USE THE G3 AS A PREFILTER.


After realizing it was the pump, I wanted to make sure the fuel/fuel pump system would never have an issue like this again. If there was an issue I wanted it to be something on the engine or engine management side of the car. I settled on a fuel surge tank. It was the easiest way to get rid of a fuel starvation/Fuel pump issue without modifying the fuel tank or putting in a fuel cell.

So I did this.


I created a Plumbing Nightmare!!

So I purchased a new walbro pump, a low pressure carter pump, fittings, fuel line, and a surge tank. I didn’t want to put the tank in the cockpit, as I wanted it safe(er) and I didnt want it in the engine bay because it seems cramped enough already. I mounted it where the stock 280z fuel pump is. The tank barely squeezed in(and created a lot of pumbling headaches.)  I ran through about 20 different configurations to get everything to fit right. (headachesss). I ended up cutting a couple of holes and putting the low pressure carter pump and 100 micron fuel filter in the spare tire wheel well. Not what I initially planned but I have plans to seal the wheel well off later.


Safety is #1

After the low pressure pump was sorted, the feed line from the walbro and the return from the engine and return to tank had to be sorted. After sore fingers and headaches:


Hard to look at.

After many do overs…


I was left with a very quiet setup an I’ very happy with the results. But If i ever did this again I would get the fuel command center FITech makes:



Given the cost and amount of time taken on my current set up. This is a steeaaal. I need to confirm if it would fit in the stock fuel pump location though..

Hope this helps, Cheers!

Datsun 280z to 240z Front end conversion!

At the end 2016 Black Dragon auto, a online store for many older classics, announced it was going out of business. I remember reading on the forums that they had reproduction early 260z bumpers available and can be had at a bargain of $130 shipped over the more expensive 240z bumpers($300+ shipped). Though there are some differences I always wanted to go this route as I didn’t like the wide gaping hole in the front nose that the Z’s have when you take the bumpers off. I always kept the Black Dragon Auto 260z bumpers in the back of my mind until they announced they were closing (SALES!). I now have a brand new 260z bumper.


Of course, the bumper doesn’t come with any hardware. I ordered some 240z to 280z conversion brackets off eBay ($50). They bolted right up to the original bumper shock locations and placed the bumper straight and tight to the body.



I was satisfied with how everything bolted up but a deal came up on craigslist that I didn’t want to let pass: 240z valence with aero lip. Not the typical 240z from air dam but allows me to have a 240z front end :). Gives a much cleaner look imo.


So Clean, So Dreamy…**not mine**

The Air dam.


Red with racing stripes aka FAST


Mild Crack

Test Mounted


Notice the droop because it was hitting

During the test mount I noticed a couple of places on the frame I needed to modify. The horn mounts and the lower grille mount wanted to be in the same place as the air dam. Quick work with a sawzall and it cleared.


Interference areas

Took care of the fiberglass damage, then sanded and prepped lip



Painted it gunmetal metallic to match my rear fenders!





Now I just need 240z Turn Signals! Maybe I’ll whip something up instead..
