S130 Fairlady 280Z 2 seater

I was reading you match ported the manifold. Do you keep the intake manifold smaller than the intake port inlet for anti-reversion?

[peter mc]

no no no it should be the same not bigger not smaller matched perfect on the inlet .... the exhaust is where we play with reversion

[d3c0y]

And tapered to the back of the valve right?

 

Damn internets lying to me again - you just can trust what your read on forums can you? Haha 

[peter mc]

um no theres more to it than that ,there is lots of terns and shapes on the way to the valve that make up the port, air does not like to change direction at high speed so in the port you need to slow it down for the corners and and make it turn and still have it moving fast so it fills the chamber ,,, close to 250 - 300 fps so it moving fast lots of work to get it right

[luvemfast]

Look forwards to picking up this bad boy.

 

GERHARD, if you're reading this. I'll be passing you soon 

[luvemfast]

I've been holding off the updates for a while, but can wait no more.

 

As you can see from the pics Peter has posted, the motor should go quite well once fitted.

Simple right? I mean, all you do is slot it in, connect it up and fire her up........... Epic fail!

 

One Friday night, Lurch (with his trusty sidekick, Jane) come over to help me put it in the engine bay. As you can tell from the pics, it has an Arizona Z Car cast aluminium sump. THIS WILL NOT FIT A 280ZX

The AZC sumps hit the cross member (by about 100mm) on S130 Z's. 

So as we couldn't fit it. Lurch volunteered to mod a factory sump, as I wouldn't dream of butchering the AZC one.

 

So here are some pics of the new winged and baffled sump. Its based loosely on the AZC unit and a Neil Cartledge sump. It would have been good to have hinges in front and behind the pick-up, but restrictions meant it couldn't be done.

 

Also note the alloy pulley on the waterpump. This is to drive the power steering, since the ATI balancer only has 1 fitted. I could mount to the front of the balancer, but would then need to make pulleys for the tensioner and pump. This way, only 1 is needed instead of 3. The pump mount needs some material removed and the bolt to be moved, for clearance issues with the belt.

 

Now the winged sump is on, there are no more clearance issues with the cross member. This should slot in nicely, right?

[luvemfast]

Here are some pics of the AZC sump mods I did, now fitted with an oil temp sensor bung.

I turned and screw cut it out of brass, then milled a hex on it and used a teflon washer to seal it. Then it required the sump to be held on an angle plate, to allow a flat to be machined (spotface). Then drill and tap a hole for the bung to be fitted.

 

It came up well, shame I can't use it  :'(

The oil temp sensor and retainer were bought from MAS and Ash was kind enough to just pop it in the mail, all for under $40 

(sensor in pic is the old one that is damaged)

[luvemfast]

Ok, so Peter called me after seeing these pics.

His head was about to explode me thinks.

The info given to me by the goons at the part supplies was incorrect.

You cannot use the engine enamel on the inside of the engine 

Apparently it turns to mush in the oil and certainly WILL cause failure to the engine.

 

[Riceburner]

I thought it was powder coating at first, nice save that could've been a disaster.

 

Does the fairlady have an oil temp sensor as standard? Are you running an oil cooler? How can you tell if a cooler is required? I don't run one and only have a stock sump 

[peter mc]

mmm Gareth next time you are at the island and you are going in to Honda watch your oil presher gage ....then you will get a sump

[luvemfast]

Bugger bugger bugger bugger 

I've just written out a massive page and it got lost and I can't remember nor be bothered re- writing it  >

 

PMC engine install............. Take 2

Dad came around Friday night and we started out in the garage at about 8pm. Then Peter calls......

"Is it in yet?"

You wouldn't believe how many times I've heard that. 

So we get it in and feel a little happy to finally get it in. Thought we'd get a head start on bolting the other bits on starting with the exhaust.........

Dad- "Ummmmmm........... Simon............... It doesn't fit!"

Me- "Bullshiit!" 

 

He was right.  :'(

As it turns out, the secondary totally comes close to the factory sump. And we went and fitted a 50mm box to the side of it? *face slap* 

So Saturday morning was spent removing it oncemore, then cutting the sump and trial fitting it until it looked better. *Double face slap*

 

I'll fix it up through the week......... You may now begin, John!

[luvemfast]

You may now begin, John!

Hmmm, someone has a new job.........

 

3rd time's a charm

So I cut the sump wing and fabbbed up some new side walls to clear the pipes. I considered just getting rid of the lot, but want as much capacity as possible.

After much sandblasting inside the sump as per Peter's recommendation. Then welding, cleaning, cleaning, cleaning and some more cleaning. I checked that it was not going to leak one last time, which it didn't, which is good. 

I fitted it back on to the engine and painted it all up again.

Now before installing back into the engine bay, I test fitted the exhaust. YAY..... Its fits 

Put it in the car and bolted all the goodies back on. They all fit....... YAY

After the 2nd "trial" fit, I noticed the power steering pump was buggered. Lurch helped me out with a new one, its now been cleaned up and halfway painted ready to fit. The mount bracket also needed some mods. It needed to have some clearance machined and a threaded insert brazed in to allow the bolt to come from the other side. This was to allow the belt to be powered off the water pump pulley.

So here it sits at the moment, so close, but yet so far.

 

Note the brand new Mikuni 44PHH's 

[luvemfast]

Also weighed my lightened flywheel and compared it to a stock one.

Works out to having 2.5kg off it

Happy with that 

[d3c0y]

What is the total flywheel weight now?

[Riceburner]

Will you get much heatsoak with the sump, the headers still look quite close.... Could just be angle of pic

[Sirpent]

I'll fix it up through the week......... You may now begin, John!

 

"What you talkin about Willis?"

 

Lets put this in perspective

 

I'm a shonk CAD junky wanting to plan everything but have little to show for it (At the moment) as far as physical work !

You are a CAD expert who refuses to plan yet has a lot to show as far as results even though they are flawed ! LMAO

 

I'm just kidding Buddy, lets buy each other a beer on Saturday, I'm looking forward to the banter.

[MaygZ]

Hey Justin,

 

who did your flywheel?  What specs did you give them?  Did they need clutch/pressure plate specs or model?  Did you get it balanced at the same time?  How much?

 

George

[luvemfast]

Jake, the stock fly weighed in at 11kg. While the machined one came in at 8.5kg

It is pretty close Gareth. Might have to put some heat wrap on, but plan on upgrading to ceramic SWR headers (Nissan Motorsport headers not looking even close to being possible). Maybe an oil cooler too.

George, I pulled it out of my parts bin. Don't know much about it really. Got a 4140 billet super light unit without ring gear, but it needs $'s spent on a clutch.

The sad part is Johnno is, there had been planning

I've had Lurch and the big Mac giving me crap about it only being an hours work to get it running again........ But it took me 2 hours to fit the air box and more prepping power steer bits 

[MaygZ]

Hey Justin,

HUHUM!!!  Mr Beeber, when you are ready!  Answer the farking questions!

 

your truely

Think you need    george 

[luvemfast]

Think you need    george 

Lol

What he said 

[luvemfast]

So I finally got some quality time in the garage to get this thing running. As per usual, there were some hiccups, but that's to be expected.

I have copped some crap from guys telling me I've only got an hours work to get it running. But it took me 2 hours just to fit the airbox! (didn't help that I gave it a cut and polish though  )

 

I finally have everything connected and fluids where they should be. Feeling nervous and excited all at the same time.

The first thing needed is to prime the oil system. So the plugs come out and I hop in the car and turn it over. Now I've never turned an engine over without the plugs before, I was suprised at how quick and quiet it turns. So I thought that there was something wrong. "The starter must be jammed, isn't throwing out" was my first reaction. Der.  It was all good though. I was concerned about the oil pressure not coming up enough. After a few calls to Peter, he reassured me it was all good.

So the next step was to put the plugs back in fire her up. It did it with ease, starting much quicker than I was expecting. The oil pressure shot up straight away also. As instructed, we ran it for about 15 minutes holding the revs around 3,000rpm. Then dumped the run in oil. Topped her up with new oil and changed the filter. Fired her up and went to sync the carb's and set the timing. Then we got a horrible exhaust leak. So we killed the motor and waited for it to cool down a bit to re torque the manifold to the head. Thinking we may have blown the manifold, and have to pull it all off. Started it up again and the leak was HUGE. Put my hand down near the leak and could feel a STRONG leak. Killed the moter and discovered that the O2 sensor bung from the EFI, had vibrated out as we'd only put it in by hand  tightened it up and all was good again.

At this point, it was ready to take for a drive, so jacked it off the stands and dropped the wheels onto some blocks. Hmmmm, the clutch feels a bit funny, tried to drive off. Nothing........... Uh Oh  :'( Don't tell me I'd stuffed up the install?  hopped underneath and saw the clutch slave cyl was fully extended. Bleed it and away she goes 

Took it for a drive up Mount Dandenong to bed in the rings under load. Watching all the gauges, making sure they were all where they should be. But not totally happy with how it was driving.

Oh, did I mention this is the day of the Christmas BBQ at Gordo's?

So I go home and get ready to head up to Wandin. As soon as I get there, Peter has his head under the bonnet, tinkering.

Checks the sync, idle and timing. After much nagging from the Big Guy, we head out for a drive....... And its terrible. Runs rich for a bit, then leans out. Peter says its the fuel pump not being able to keep up. We head back and have a nice afternoon standing around yacking about all things Z's.

I'm not entirely convinced about the fuel pump issue, but can't let it go. As soon as I get home, I remove the fuel return line and put a fuel pressure reg and set it to 5 PSI. take it for a spin and its no different.

Go hame and reduce the pump and main jets. take it for a spin..................

AND SHE'S A FREAKIN ROCKET!!!!

This is more like it and I've got the biggest smile on my face 

[dat2kman]

Vote  1. For Simon, excellent result, and looks sweet, mucho s130 lovin!

[luvemfast]

Cheers Jason, was a fair old effort to get it to the BBQ.

Jason was at my house on Monday and saw the state of the car from then to now 

 

On a side note, my wife gets Coles online and farmers direct delivered. When they saw your van, the neighbours thought we were getting chocolate delivered  ROFL (they didn't realise you took the rally car away)

[peter mc]

good to hear mate  looks great to
