You can also see yet another custom part I had to machine laying on the workbench :lol:
I made an adapter for my dial gauge to screw into the back of the injector pump so I can set the timing once it goes back on.
i must say it's one of the jobs I'm nervous about, but it has to be done :salute:

Thanks guys :thumbup:

Back home again from CT, so this weekend is crunch time.
We got back from CT at 3pm and by 3:30pm I was under the bonnet again :lol:
Injectors are back in, injector pump is "in" but not calibrated yet.

This weekend I want to set the pump up, bolt all the bits back together and finish the exhaust.
Then it's just the air box (which is almost done and looking sweet) and the hood scoop.

I'm tired of not having wheels so the pressure is on to get it going.

Pics soon.

So gents, the moment of truth arrives and... IT'S ALIVE ! :blonde: :blonde: :blonde:

So many hours of research, talking to the experts, gathering parts, fabricating parts, spinning spanners and it all comes together in the end :woo:
The build isn't 100% complete as I still need the airbox, hood scoop, the rest of the exhaust (only 600mm long at the moment "Tinus style" :biggrin:) and final clean up before I start fine tuning the boost and fuel on the dyno, but it feels so good to hear her roar.

Getting oil pressure for the first start up was the most nerve racking thing I've ever done !
After draining and dropping the sump to fit the oil return line, there was zero oil pressure :surprised:
Like Michael & Tinus said, it's common on the TD42 and you just have to man up and swing it and idle for a few seconds to bring the pressure back...tense seconds !
The injector pump is a bit noisy, but I'm assured it's normal.

Aligning and calibrating the injector pump was a job and a half.

Once I've got the whole project completed, I'll put up all the parts and pricing for those who are wanting the do a DIY conversion.

Here's a video of the first start and then after a few mins of idling to lubricate everything, I gave it a few small throttle blips.

The air box is almost there.
I gave the final approval to weld it up and polish today, so hopefully I'll have it in a day or two.

If anyone wants one made up, drop me a PM.
Not cheap at all (+-R38 more than plastic one), but will outlast the rest of the car.
It's designed to take the OME Nissan filter.
I'll eventually put it on the 'market place' board.
I'll post more pics once it's done and installed.

Hahaha...the smile was suppressed by the grimace of waiting for something to go boom or "tuk tuk tuk" :rolling:
Thankfully I had lots of help from team turbo as I went along.

I've made a start on the hood scoop.
The plug is still a bit rough, but nothing lots of sanding can't fix.

I took an off cut piece of polyurethane foam (surfboard foam) to form the plug.
I printed the side profile at true size of the front, side and top profile and glued the prints to hardboard, then cut 2 of each on my bandsaw.
I used these profiles on each end as a sanding guide, so I could sand until I hit the profiles to make sure the shape was uniform.
I left about 20mm extra on the bottom for shaping to the bonnet and making the trim line.
I mocked up the position on the bonnet then using a 20mm thick gauge block, ran it on the bonnet with a scribe to mark the profile of the bonnet along the bottom of the plug to get the shape of the bottom so it sits snug on the bonnet.
Then I glued strips on the sides and shaped them according to the profile line I traced.
I applied a thin layer of body filler to the foam and sanded it smooth to seal the pores of the foam.
I used good old polyfiller as a filler layer to find any low spots in the body filler as the colours differ to show up areas easily and polyfiller is easier to sand.

Next I'll smooth out the polyfiller top layer and apply the release, then a nice thick gel coat layer and 4-5 layers of polylite resin and chop strand matting to form the mold.
Once I've sanded the mold through the grits to 2000 grit water paper, I can apply release and mold the final part with a white gel coat layer, 4-5 layers of 5oz woven epoxy matting and epoxy resin.
Finish off with some 1.5mm woven stainless steel mesh to stop the troll sucking up leaves, twigs, rodents and small children :rolling:

I'll post pics as I progress.
Once I have the mold I can pop out copies if anyone wants a scoop for a top mount intercooler.

On the underside of the bonnet I'll make a flat 'flange' surface and I've bought "D profile" automotive rubber to seal down onto the intercooler to prevent air loss into the engine bay.
It will also help the auxilary fan to suck air through the intercooler for when I'm not travelling fast enough or the intercooler develops a bit of heat soak from the engine below.
