Long term D22 build

Last week motor finally cracked a piston so decided **** it, let's build a tough motor. Plan is rebuild with precision international kit, do the head up open the ports up ect, custom exhaust manifold, gt25 turbo, W2A cooler, lift pump, air filter, boost controller, tune, egt/boost gauges, fuel filter relocate, body work, suspension, steel tray, long range tank and clean up wiring. Will post photos of progress will take some time as I'm a poor busy **** lol.





Photos of an old head we are gunna cut up to see what we can do to the head

Look forward to seeing how you go with the build... Just out of curiosity I gather it's a ZD30 engine? Any idea why the piston cracked? How many k's on the engine? I take it you didn't have an egt gauge installed. Any other mods on the old engine?
Sorry about all the questions- I'm just interested as we don't seem to hear about too many bottom end failures on Navara ZD30's on here. It's usually cracked heads due to overheating!

Cheers,

Ben

Yea it's a zd30 in a 02 navara with 270k. It's really common here for the engine to crack a piston here rather than heads. Some say it's dribbling injectors but mine have only done 20k since pump and injectors had been replaced. The top of the piston gets to hot and cracks from over fueling under cruise. My egr is blocked and I've got 3 inch dump into 2.5 straight through.

Fair enough, I thought that was mainly a Patrol problem! Anyway, good luck- keep us posted.

Happens to a limited bunch of the early d22s, seems like anything after 2003 is safer.

Parts arrived today so will get busy over the weekend. Before shot of engine bay as a lot will be changed.

Hey mate good luck with it.
Lots of pics and details please.
Could well become one of the best threads on here.

Few hours in the shed tonight.

Slowly clearing the bay out

All parts that are no longer required

Butterfly delete

3 inch dump pipe I made. Make an offer

Modified egr. Hopefully I can just delete it out of the ecu.

Upgrade of wheels got sick of the rusty steelies.

Turns out number one piston has died.

New piston looks different to the old piston, apparently they changed around 2004. You can turn the egr off in the ecu by the temp map.

Yea I was reading that in the tune thread. That's the plan. I was hoping I would be able to remove it completely. New pistons are

Ever seen a dual cab well body on a single cab? Just sat on there for storage. This is my parts car

New tyres


Motor is fully stripped down. In the process of cleaning. I'll take photos as I go. New turbo setup will go on after we get the pcm sorted and intercooler gear collected.
