DJZ's DR30 Skyline

[DJZ]

So ignore those posts about changing the alternator, I put the original one back on today - the battery light goes off like it's supposed to now.

Got my front 5 stud hubs today, thanks James! Now I just need to fix the rooted rear one, buy some new brakes and wheels and chuck it all together. Easy as that!

Had a bit of a play with the fake Tial BOV that I bought for the Z originally, I cut down the spring too short so ended up buying a real Tial. I connected it up to vacuum on the DR while the car was running and it was opening a couple of millimetres so I shimmed up the spring until it was just closed at idle, only problem is the spring looks like it's binding up now as I can only open it about 6mm. Time for a new spring, just need to find my boost gauge that works and see what kind of vacuum it's actually pulling when warm.

My new injectors plugs showed up from the US today so tonight I chopped the injector plugs and also the water temp sensor plug off and soldered on the new ones, I also cleaned the terminals on the injectors and temp sensor, 3/5 sets of connectors had quite a bit of corrosion. The car seems to run a little bit better now, doesn't seem to pop/miss at idle which it was doing a little bit before. We'll see how it goes tomorrow when it's cold.

Hooked a boost gauge up today to see what vacuum it's pulling so I can order a new spring for my fake Tial BOV, looks to be around the 19 - 20 inches mark which is not too bad, it goes up to about 22 - 23 after I blip the throttle.

Ordered my intercooler finally today, it should be here tomorrow or Wednesday. Will have to have a look at mounting it and see if I have to remove the air con dryer(?).

good work, sounds like its progressing nicely

Got my intercooler today, it's pretty averagely made and feels pretty light but it'll do the job. I jammed it in the front to have a look, definitely going to have to remove the air con which is a bit of a shame but it doesn't work anyway. The cooler looks quite good in there, I'm going to try and get it as centered as possible, I don't like things being offset

I got a new fan switch as well, drained all the coolant out, removed the old switch, went to put the new one in and it looks like the thread is different. It looks tapered (possibly 3/8") where it should be 16x1.5. I'll have to ring up Tridon tomorrow and get them to check their other ones as it's the right part number and the description says it should be 16mm.

Took some photos but I can't be bothered going through the rigmarole of trying to get them off the fancy camera tonight, I'll do it tomorrow.

Ended up just recutting the thread on the temp switch, it was definitely 3/8" BSPT by the looks of it. Fans both come on now when the gauge gets to about 3/4 of the way up.

I yanked out the air con today and the intercooler is going to end up something like this. I had to remove the headlight to open up the hole for the piping a little bit and ended up breaking one of the studs off, they were really rusty. I drilled it out and tacked a bolt in it's place. The only part I'm not really happy about is the pipe between the intercooler and throttlebody just after where it comes through the radiator support. It's a bit annoying as the power steering tensioner is really high on the motor as you can see in some of the pictures so I have to have a 90 degree then a 45 degree to meet up with the other pipe. I'm probably going to weld on a 90 degree bend to replace that silicon then still have the 45 degree. I'll be welding the pipes together to try and get rid of as many silicons as possible.

The other problem is the air flow meter piping, I might have to change my filter from the K&N to something a bit smaller to fit in the gap that I have and get another silicon bend to hang the air flow meter over the pipe out of the turbo. There is heaps more room with the air con pipes out of the way. Things aren't going to stay like this forever anyway once I change the exhaust manifold and turbo.

Wow great effort as always. Not my thing, so I am real naive, if you are going to be welding alloy any way is there a possibility of turning you intercooler outlet round and running you pipe to the throttle body round that side, and not across the front and back? Seems you air has to travel a long way

[DJZ]

Yeah, it does seem that way but the radiator support had already been cut on that side for the old intercooler and I didn't really want to cut up the other side. I'm trying not to destroy the car too much just in case somebody wants to put it back to standard one day after I sell it

[DJZ]

Decided to put the intercooler in tonight. It's not 100% finished but it's in and plumbed up. Seems to have made a bit of difference, the car feels a bit torquier.

I need to get one more length of the shiny pipe to replace the piece of thicker walled dull finish pipe and I found an ali 45 degree so I can replace one more silicon.

Also bought an almost complete N/A FJ20 for $112, might have to find some twin carbs and a 1600 to put it in.

I like the way you think, and some of the deals you get. Well done, look forward to seeing this progress.

Here are some pics of the intercooler, will try and get the last piece of pipe this Saturday and either a mushroom type air filter or another 3" right angle silicon to replace my current not very sealed air filter setup.

After the rain the other day I discovered about 10 - 15 litres of water in the side well in the boot. Had to drill a hole in the bottom of it to drain it out, after all the water was out I had a better look and it seems somebody has welded a patch in there where the original bung should have been (probably because it's started rusting) and then hasn't drill a hole in it, idiots.
