This project started with this:

p940177_1.jpg



My 280zx turbo. Poik (turbobricks and ls1tech) and I drove from Edmonds, Washington, to Grant's Pass, Oregon, to get a Turbocharged 280zx with T Tops, because there were like two in Washington for sale, both of them being rust buckets.

Note: long. f*cking. Drive.

Next, I purchased a fuel rail from Pallnet (Great guy, hell of a product), along with a set of 311 cc\min N\A Supra Injectors. I did not do any tuning. I simply bumped my boost up.

After deciding my car was considerably slower than before I did my little "upgrayedd" (note: with two d's, for a double dose of this fuel), I decided to embark on a journey towards Megasquirt. A journey which would make my family question my sanity, and eventually hold me as brilliant for "Boeing-ing my car, rather than pimping it out".

Turns out the '81 l28et is the only one of the L series motors which can not simply be modified to trigger megasquirt. Believe me. It was a bitch. It has an optical crank angle sensor, which sucks. I ended up just pulling the crank pulley off, drilling three holes in it, gluing magnets into it, and running a hall effect sensor. AMAZING how simple it was to get running. It took like six months to finally just do this simple, $60 triggering system.

Here are a couple pics of the first iteration of my megasquirt harness:

So, I decided a year after installing MS (and two years after buying the car), that I'd like to buy a 240z. I like the lines better, it's lighter, has about the same space in the engine bay, and the interior is WAY cooler looking. More round instead of boxy edges. From now On I'll be referring to the 240z as the S30 and the 280zx as the S130.

Here's a pic which fully encapsulates the condition of the exterior:

^not me. my girlfriend.


And here's one which fully encapsulates the condition of the interior:

p940177_6.jpg



The dash, is frickin perfect. I saw the dash, and knew this was the car for me. I've never seen an interior in as good of shape (without restoration) as this car. I decided that was a good indicator and bought it.

Shortly after, I realized that the Holley 4 Barrel carb on the L24 (inline 2.4 liter) was a piece of crap. It only ran nice about 4k+ rpm wise, and a buddy of mine who knows about things such as carbs (knows a 4 bbl up and down), could not help me tune it at all.

^setup that came with the car


I bought a brand new Holley 390, as well as the 4 barrel intake from www.arizonazcar.com. I powdercoated the manifold black:

I did not get a pic when it was all done (like having the carb installed), but you've seen what it looks like. Imagine the first pic without carbon buildup.

So, After the new carb was installed, and everything was all gravy, I drove the car. Whee. That little sucker hauled ass.

For about a week and a half.

Now, when I buy a car, I change the oil, spark plugs, etc. I check the oil every time I drive it for a week or so, to make sure it doesn't leak. The car didn't leak oil, it didn't burn oil. The friday following the carb install, I checked the oil, perfect. I drove up to my parents' place, and parked the car. I drove my dad's pickup for the weekend (hauling dump runs and such). On a side note, here's a pic of the truck a year or so prior, after racing and beating an 11 second mustang at the track in Bremerton, Wa:

DSC00044.jpg



Note: Poik and I won the race. This happened on the way home, doing 50 mph, steadily down the freeway. This is a thread for another day, however.

So, Monday morning, I get in my car (didn't check the oil this time), and got on the road. I got from Monroe to Kenmore:

p940178_1.jpg



Before I noticed a rattling sound. I immediately pulled over, checked my oil. Bone dry. I walked to shell, bought 5 quarts of oil, dropped it in the motor, and checked the oil. The motor was hot, so all the oil heated up and dropped to the pan, and the oil came up to the "okay" mark on the dipstick. I drove to work, and worked. After work, I checked my oil, it was full. The motor, was not leaking any oil. I drove home. On the way home, however, the L24 went tits up. There was no oil sitting at home on the driveway where it was parked for the weekend, and there was no burning oil smell to the exhaust. CERTAINLY NOT 5 QTS IN 20 MINUTES OF DRIVING worth of burning oil smell.

So, at this point I have a car with no motor, and a turbocharged motor with the same mounts and all that, in a car with a 3 speed auto tranny, and inferior looks and aesthetics.

I swapped the turbo motor into my s30. Whee! I also rewired my MS Harness. It sort of looked like this:

sm_photo_missing.jpg



Yeah, I don't have a pic of the harness in the s30, but it didn't look any better than the original.

Poik and I tuned the motor, Greg helped a lot too. Here's a pic of Poik and I pulling the motor out of one of his 300+ hp volvos:

p940178_2.jpg



You can't see the volvo, but you can probably see that we're fun people. Funny faces in pictures, remember those days? Note: my front left tooth is fake. I know. It looks stupid. Shut up.

Anyhow, I drove my car a lot, and it was fun.

Next up in the list of fun stuff which has been a pain in my ass: Replacing the passenger side frame rail. Suddenly the car started veering right really hard when I hit the brakes. Turns out the subframe rail was rusted through and needed to be replaced. I replaced it with a piece from http://www.baddogparts.com/. It was an awesome piece, and I'd recommend it to anyone who needs to replace their frame rail.

Luckily, my neighbors build cars. Actually, they restore cars, but at the level that they work, I consider it building cars. I've seen their work, and it's f*cking amazing. They restore Jensen Interceptors. I'd never heard of a Jensen before I met Doug and Keri, but they seem to be really great cars. Anyhow, Doug allowed me to use his shop to replace my frame rail, and when it became apparent to him that I didn't know what the hell I was doing, he helped me out by essentially doing the whole job for me. Essentially, I'm in debt as far as work time goes. Whenever I'm at my parents place and I have a spare minute, I ask him if he needs any help. He really bailed me out, and didn't ask for anything in return.

Anyhow, here are the pics!

Before any work:

p940178_5.jpg



So, Doug told me to start cutting sh*t away. Here is that:

p940178_6.jpg


p940178_7.jpg



He asked me to pull this (don't know what it's called, damnit) in one piece, so we could use it to fabricate other pieces:

So... After measuring all that we had to fab, we started bending:

sm_photo_missing.jpg



Then we bent some more:

p940180_1.jpg



From another angle:

p940180_2.jpg



How's it fit?

p940180_3.jpg



A little floorboard repair while we're at it, Poik helped out here:

p940180_4.jpg



Building an end piece for the new frame rail:

p940180_5.jpg



My baby, pre-paint:

p940180_6.jpg



Ripped the old frame rail out:

p940180_7.jpg



Welded the new wheel well in:

Fitting the new rail:

Didn't take any after pics... damnit, lol

I'll take some the next time it's on a lift.

So I decided to start painting.

sm_photo_missing.jpg



Pretty much skip the boring stuff. Taped, primed.

My girlfriend decided it'd be a cool idea to put this on the hood:

p940181_1.jpg



So, we cut her drawing out, and started painting.

p940181_2.jpg



I also decided to shave the rear bumper while this was going on:

Finished product:

The motor:

The Mounts Clifton Designed, which I, shamefully, will be copying:

p940183_1.jpg


p940183_2.jpg


p940183_3.jpg



I plan to cut the exhaust at the first bend and just rotate it 180*. I hope to.

p940183_4.jpg



And just for the hell of it, we dropped the motor in with a crane to see how badass this thing will really look:

p940183_5.jpg


p940183_6.jpg



Once the motor is swapped in, we're planning on putting a small jacuzzi or spa in between the pulleys and the electric fans. Maybe a batting cage, I really have to think of my options, I don't want to let all that space go to waste.

Ahhhh I can just see it now. In ten years, the majority of 7MGTEs will be in mk2s and Z cars. While the previously 7MGTE'd MK3s will be 1J or 2J :x
