Pezhead's Svg30 Time Capsule Saga

[Pezhead]

Stock R180 Open diff in it. Not sure what I'm going to do yet. All upgrades are pretty expensive. Have to sort that out when I get it to Oz. Trying not to start any new mods I can't finish while it is in the U.S.

[Pezhead]

Yesterday's progress report. Spent a few hours re-checking and labeling all of the loom wires for the ECU. I was hopeful when I found some kind of black box control unit that wasn't plugged in. That didn't do it. Then found one wire in the loom harness I had labeled "POWER" 20 years ago that wasn't on the diagram chart. Power to that brought the ECU to life! Horray!

Next was spark. The coil wires were on the chassis loom that got hauled away. Spent a few hours trying to figure out how the trigger wires from the ECU were meant to trigger it. Hard wiring the coil didn't yield any spark either. So that meant the coil is an electronic ignition type. Some google research yielded that there is a transistor unit for it. I was just about to give up hope when I found the tiny unit in the box of parts I had stored with the car! Amazing! Put this stuff away 20 years ago and it was still there.

Luckily google found me a diagram on how to wire it in. So now I have spark!

Next up will be to re-route the wiring into the cabin.

I needed a victory reward for all this work, so decided to put on the flares as my reward. The flares don't fit great, but I bought the rubber welting kit that will help with that. Not going to install the welting until the car gets painted (eventually after shipping it to Oz).

Looking sexier all the time.

Hurry up and bring it over so I can have a steer

[Pezhead]

So, I have a few day's worth of diary to catch up on.

Tidying wiring sure took a lot longer than I expected. It was nearly a whole day of wiring in the E.C.U., Fuse Block and relays for fuel pumps and injectors.

Then it was on to finally dropping the tank and replacing all of those hoses. Luckily it wasn't all that hard, just time consuming.

Next was that wheel cylinder. But of course I had the wrong one. There was a part change in '72 and wouldn't you know it, I had the wrong one. So that went back to the parts store for a refund. Oh well, I know which one I need now.

Then I tested the fuel system for leaks. It all looked good, no leaks. And you can hear the fuel draining back into the fuel/air separator tank and back into the main tank.

But then cranking yielded nothing. Didn't want to kick at all. So I checked the spark and that was working just fine. No fuel smell out of the tail pipe either.

There was voltage going to the injectors, but I couldn't hear them "tick".

A spray of starter fluid and the motor kicked to life! Success.... well sort of.

This was the last day before I was to leave again. So looks like there is going to have to be third installment somewhere down the track.

So back into the auto cocoon. I had to pack it away again until my next trip to the States.

The ECU tucked up nicely to the passenger kick panel along with a new fuse block for it.

[X]Figure out why the ECU isn't getting powered up and get engine fired up and running

[Pezhead]

and a video of the start up. Sounds pretty rough, but I doubt the starter fluid could make it through the throttle body all the way round to the front cylinders.

At least I got to hear it run after 20 years of sitting!

[Aggroman]

and i thought twin 044's sounded annoying..

[Pezhead]

Yeah, that 044 really rattles! You should hear it inside the car!

[zebra]

This is going to sound mint when it running on 6

[Yo-Yo]

[_]straighten the datsun badges on the front left quarter

Well done Mate, you got a lot of the tricky stuff out of the way at least

Remind me to pick your brains later on about wiring up a kill switch

[Pezhead]

So I'd like some opinions on Nistune. My goal for this engine is to get 300hp to the rears. Shouldn't be too hard with the 3 litre V6, better turbo, intercooler and a bit more boost.

Since the injectors are assumed to be shagged I should uprate the stock 260cc ones to something more along the lines of 400-500cc. But then I definately need to remap the ECU.

I'm thinking for this simple set-up Nistune should meet my simple needs.

[Plattsy]

i run nistune pez, ive had no issues with it what so ever.

[Pezhead]

Thanks. I know it doesn't do all the fancy stuff a standalone system does, but should meet my simple needs.

[Plattsy]

Thanks. I know it doesn't do all the fancy stuff a standalone system does, but should meet my simple needs.

my thoughts exactly, on an old engine like yours and mine, there is bugger all need for an adaptronic and all that jazz.

also cant speak highly enough of the nistune guys. constant emailing asking me questions about my setup. making sure they got the base map spot on.

[DekA]

I had Jez install and tune the nistune in my car Eric. Haven't had any issues with it.

[tweety bird]

This is going to sound mint when it running on 6

this.

i can't wait to see it.

[Pezhead]

Resurrection time, well in a few months.

I just booked tickets to go home over Christmas this year.  I wonder if I will brave the cold to go out and work on the 240....

[Pezhead]

Some fairy tales start with a fairlady in waiting. My princess is no different. And now I'm in Seattle for just a quick visit, I needed at least to pay her a quick visit and a little attention.



Here she is, just as I left this saga 2 and a bit years ago. Last time we managed to hear it fire but only with starting fluid. Fuel pump is hard wired and fuel is reaching the regulator, but doesn't seem like the injectors are firing.

So I did some research before I left Sydney and found that rb20's use the same high impedance and cc as vg30et motors. So I got a used set before I left.
Of course it is a lot of junk to pull to get to them.



And of course the stock set up has crimps on both sides of the injector. So a bit of cutting (and swearing) has all the old injectors free and should be good nuf for a slip on and clamp test fire.



So tomorrow will go get some hose clamps and gasket seal to bodgey up the plenum back on.

That's pretty much all all I have time for this trip. Just enough time to give this test over a couple of days. Wish me luck.

[Pezhead]

Today's instalment is a special one.

Yesterday I reinstalled the injectors and gave a quick test with manifold off to see if they were firing fuel. It was a no go. So back to a lot of internet research and theories why I have spark but no injector signals.

I thought that maybe the hard wiring of my fuel pump may be messing with the ecu. A lot of forum scouring led to a post that the ecu uses ground to the fuel pump relay to control it.

A bunch of wire tracing and diagrams over the next whole day finally led to the wires to cut and spice. Well, why not go for broke.

The fuel pump did the correct 5 second prime and shut off. But cranking didn't fire at all.

At this point I was very bummed. I fly out tomorrow!

So, wanting to at least hear it run I went and got some starter fluid. A good spray and kit kicked a little. Another spray and she kicked to life. To my surprise it kept running! The fuel must have just been too stale to fire on its own.

OMG! 20 years ago I bought the engine and started this conversion! I put it in gear and eased the clutch to move forward a foot. It moves under its own power!

I didn't dare take it for a spin. Still too many wires to tidy up and a leaky rear brake means it can't stop.

But I can certainly fly out tomorrow knowing I'm that much closer in this saga.
