Hi all, glad to be over here :). Hopefully I'll be welcome even though I don't own a Navara :scratch:. I normally frequent the Almera Owners Club and Turbo Diesel Owners Club, but thought I'd come and say hi to you guys here and try and dip into and share a bit of knowledge about the YD series engines.

I have a 2003 Nissan Almera SXE fitted with a YD22DDTi. This is the common rail injection engine put into N16 Almera from 2003-2006, not to be mistaken for the direct injection fitted to N16 Almeras from 2000-2003. Standard they are 136bhp 222lbft. I havnt had a chance to look around this site yet but is anyone into tuning their YD25? I've been doing as much research as possible about mine and also know that the block, head and fueling system (aside from the diesel pump) is the same as that in the YD25 fitted in the D40.

Future plans are to fit a hybrid turbo with a remap. That's only if I can get someone or find something to be able to work around the Denso ECU! It's an on going project that I'm in to as an enthusiast, and I'm interested in seeing what the YD22 is capable of. It would also be good to show the Diesel haters how good modern diesels are now :).

Anyway, looking forward to chatting to you all. Here are a few sepcs and pictures :D.

Previous car: N16 2001 Almera Activ 5dr QG15DE 89bhp, Tornado Grey.

Current Car: N16 2003 Almera SXE YD22DDTi modified (last dyno @ 138.2 BHP with only exhaust mod), Techno Grey (KY5).
Bought with 34k on the clock, Jan 2008. Stock power 136 BHP 224 ftlb Torque (never rolling roaded stock so untested).

Stock Engine Specs:
YD22DDTi 2.2L commonrail injection turbo diesel. Garret GT1849V turbo. Intercooler. 18:1 compression.

Performance:
Powerspeed (Kent) 2.5" Turbo-back mandrel bent stainless exhaust. Video of sound
Larger intercooler and 2 1/4" piping.
HEL braided brake lines.
K&N panel filter.
Cold air feed.


Handling:
BC Racing BR series coilovers.
16" Rota Grid, Gunmetal/polished lip.
Falken Ziex 912, 205/50.
Autec lightweight (1.5kg) front strut bar.

Cosmetic:
Seat Leon Curpa R front splitter.
Custom front bumper taking design cues from the Australian N16 pulsar, with N16 Pulsar bonnet.
P1 rear lights.
Orange calipers.
Nissan rear mudguards, colourcoded.
Tint sunstrip.
Private plate (was a present from the parents :D).
Custom car mats, metal footplate and grey piping.
Almera stainless kickplates.

Other:
Bosch Aerotwin wiper blades.
Boost Gauge.
EGT Gauge.
Intake cleaned with Wynns EGR aerosol cleaner.

Future Plans:
Going for safe power but as no one seems to have modded the YD22 before I feel I'm breaking new ground and flying blind to an extent... all part of the fun :D
Brake upgrade; the usual stainless braided hoses, dot 5.1 fluid and uprated pads.
Weapon-R or custom engine damper.
Nismo 'Rear Sway Bar' (56230-RNB55) (discontinued by Nissan and rare so if anyone has one for sale?).
Possibly rear bumper spats from Autostyle.
Carbon bonnet from Racecraft Carbon (£580 delivered).

Comparison of how it was the day I bought it with how it looks today. A different animal.

Plans at the time of buying (not too far from how it is now :)):
Plans are Eibach 30mm springs
Remap (potential for 160bhp?)
Rota slipstream 16" gunmetal
M3 style side skirts
Giacuzzo rear apron
Seat Leon Cupra R front splitter
Paint p2 rear lights, or, change for p1 rear lights.

The guys over on PGA (Pulsar Group of Australia) were pretty fascinated by it :D. There's a guy with a Nissan Patrol on there called YoPatrol who's had some sound advice on diesel tuning.

Intercooler and pipework are all in now, with boost gauge installed too. I, like Andy, used a universal intercooler and designed the piperun to fit.

Pulls harder to 4k now and gives a smoother response at the top end. Boosting to 18psi. MPG doesnt seem to be affected :cheers:.

Thanks Joe :) Certainly is a bit of a mover 8).

Installed a cold air feed today. Hitting the drag strip next week so thought I'd see if I can reach for some gains.

The pipe.

Done :)

Test drive tonight. I'll be interested if there's any improvement on a diesel. I'll post some feedback if anyone's interested.

I had that in mind so I'm hoping the gap between the air box and outlet of the feed should mean water misses the filter. Filter is up top of the box anyway so it's not getting wet ;).

Quite a few things done since but some of the more prominent ones are Nissan Enkei wheels from a Primera GTLE, hybrid turbo from Turbo Technics and remap at RS Tuning :)

As a JAE club rep this year I was also part of a Total Nissan magazine photo shoot line up.

Turbo, which I'm pleased to say I fitted myself :)

This is a conservative map from Paul due to unknowns in that this engine hasnt been mapped before, only Lee's YD25 D40. If it runs reliable for the next 6 months then I'll be back up for another tweak.

I've also got a new intercooler and boost pipe setup on order which will hopefully improve flow and help me crack the magic 200 :). I'm going on a rolling road meet end of next week so we shall see!

It's on the cards mate for sure. I'm running 1.5 bar on this map but hoping to go to 1.7 if all runs well for the next 5-6 months. Looking at 220bhp then I reckon, and after that we'll see but I may start seriously considering getting water/meth injection.

Water meth mate. 25hp+ and poss 50ft/lb

Not if you like your engine. At any power level diesel and air will produce far less stress for the same power level. An extra 25hp for EDK is as easy as more boost and the fuel to match.
Methanol is corrosive to aluminium, it also detonates at diesel compression levels. The only way to introduce it is via the intake which gives no control over injection timing or even dosage rates.
It is also quite difficult to evaporate a meaningful amount of water or water/methanol mix in the intake of your engine. For this reason many people spray it in upstream of the turbo, which erodes the leading edges of the compressor wheel.

I just don't see the good side.

at 4000rpm it will take about 31psi boost to deliver a clean and safe 18:1 A/F ratio and 220hp on your engine.
That's 2.1 bar of boost.
At 1.7 bar and 220hp you'll be running about 16.1:1 A/F ratio, this is smokey, will soot up your engine and give EGT's through the roof.

For 200hp, you should be safe on 25psi (1.7 bar).
