jtpaintballwdp's 1970 240z "resto-mod" journal


Recommended Posts

Over this last weekend (5/26/2012-5/27/2012) I picked up a 1970 240z from my dad. He used to restore them for a living and as a result has a few laying around. The one I picked up is pretty much rust free, and was running before it was parked where its been for about 10 years.

 

I'm going to use this journal to keep track of progress and lay out a plan for my self and for others who may be interested.

 

First up, the car as it sits right now:

The Plan:

 

1. Get car road worthy/safe

a. Get car started (oil, fresh gas, spark plugs/wires, general tune-up items, ect)

b. Flush and change brakes

c. Flush and bleed clutch

d. Change any remaining fluids not mentioned in the above

e. Get front end back on

f. Make sure all lights/electrical systems work

g. New wheels/tires (Enkei Apache II with 215/60-15 BFgoodrich Radial T/A unless someone else has a different opinion)

 

2. Clean out interior

a. Remove all junk from interior

b. Remove spider-webs

 

3. Move car from parents garage to my garage (about 2.5 hrs)

 

That is the short term plan.

 

Next up will be bodywork. As I said before the car is 99% rust free. I will be removing the body molding down the side and filling in the holes, as well as any other damage that needs repairing, so far all that i know of is on the pass. side 1/4. The car will be resprayed in the orig. green. At the same time I will likely do some suspension work.

 

After that will be mechanical work. My dad is throwing in one of the complete L28ET drive trains that he has with the car. The motor will be getting a complete refresh as I see necessary. If I crack it open, and its still pristine, I'm going to throw it in and run it until it dies, AND THEN rebuild from there. I plan on wiring up a Mega Squirt. I have past experience with MS on my Miata, and feel this will be the best way to go.

 

I plan on going distributerles using LS coils (obviously controlled by the MS. Along with the coils I will also be using ID725 injectors, with a bigger turbo (haven't decided on this one yet.) I would like to see 325-350whp by the time I am done.

 

With the mechanical side of things I will also be working on some chassis stiffening, and more advanced suspension, but this is far down the road, and haven't looked to much in to it yet.

 

That's all for now. I will be keeping this thread up to date as much as possible.

First update to add, no new pics.

 

Got down to my parents house, and made all the preparations to get it the Z started up again. Unfortunately we ran in to a few issues, first was spark. That was resolved by replacing the condenser on the distributor.

 

Second issue was no fuel, unfortunately we didn't have time to work this out, but we are going to check the mechanical fuel pump and the fuel lines.

 

After the system was primed, and we had oil pressure, we were able to get it to light using starting fluid, so once we figure out our fueling issue it should start (fingers crossed)

 

We did find out that it has aftermarket Front and rear sway bars (Suspension Techniques in the rear) and a urethane steering coupler. Bonus!

Another quick update, still nothing big. Narrowed down the fueling issues to blocked lines or the tank feed. Unfortunately the car being 2.5 hrs away really cuts down on time I can work on it.

 

Also put together a list of everything that needs to be done before I can even think about driving it.

Uhaul truck and trailer, a little sweat, and get that sucker trailered back to your house. Nothing like staring at the z to get you even more motivated. plus the truck helps with all the spares you can haul!

 

This is a good point. I would if I was in the position where I could spend a bunch of money on it right now, but as it is, I'm enjoying taking my time =D

 

 

Going down this weekend to get some work done

 

Got my rotors and drums turned

New wheel cylinders/brake hoses should be here today

Pads and shoes that are on it have plenty of meat left, and aren't contaminated, so I will reuse those until my rear disc conversion, and Toyota 4x4 front conversion.

 

So brake overhaul this weekend. Hoping to get it moving/stopping under its own power this weekend.

Another update:

 

Of course nothing goes as planned.

 

I get out to MD with what I thought was all of the parts I needed, only to find that i forgot the seals for the front hub... alright Ill just do the rears and save the fronts for next time... Flare wrench is also back in NoVA. Was able to replace the pass. side rear wheel cyl. with a standard wrench, but didn't want to risk rounding off the flare nuts to the rubber hose, nor did it feel like the other side wanted to budge either.

 

So all in all I really got nothing done... I think once we get the brake system back together I'm going to take T-Bones advice and just haul it back to NoVA so i can work on it at my house. We actually have the tow dolly and a vehicle to tow with.

Just been rattling off ideas in my head.

 

So I have a L28ET to swap in to my car, engine is of unknown mileage, and has been sitting as long if not longer than the Z (10+ years). It was known running when we scraped the car it came out of, but we all know how that goes.

 

Either of these wont happen for a while but these are my 2 options as I see it.

 

1) Small top end over haul of the L28et, replace seals and all that good stuff and hope for the best.

 

2) Run the L24 for a few years, while I accumulate parts for a complete overhaul of the L28et. This would probably involve a slight refresh of the E31 head and possibly a cam to make it a bit more fun to drive, along with a header (Nissan Motorsport or MSA) and exhaust.

 

I figure with that, I could possibly recover a slight amount of money from the E31 head when it comes time for the swap, of if i decided to, I'm sure I we have an extra L28 block lying around that i could throw some flat-tops in and stay NA.

Ordered a set of Toyota 4x4 calipers to replace the seized stock calipers. Also ordered some Axxis ULTs to go with them. Hoping to have the brakes done next weekend... FINALLY.

 

Once the car is back on the road, I also plan on a rear disc conversion and a 1" Wilwood master, but this is going to be a while down the road.

Pulled the l24 this weekend, Hooray progress!  Have a little bit of rust to take care of under the battery tray, other than that the bay is going to get a deep clean and I'm going to leave it at that.

 

Once its cleaned the L28ET will be going in and wiring will commence going MS3x running full sequential spark/fuel using LSx coils that i already have laying around.

 

Though I would also finish up the brakes this weekend but alas, it wasn't meant to be.  The passenger side caliper is leaking around the flare fitting.  It looks like when it was re-manufactured, they used the wrong flare and the line is bottoming before it creates a seal. time for an exchange.
