Black DT VNT XUD Wagon

[Ruan]

Mega update:

Saved for project info for when I can be arsed to have to copy and paste it...

But latest update: 12 months ticket! Whoop! Only needed a new hub as the balljoint hole was ovallised... Oh well!

Well decided I might give this an update as to what's going on at the moment...

Basically as most of you probably know, the cylinder head keeps lifting under boost - at anything above about 23psi, it simply cannot cope and leaks a serious amount of combustion into the cooling system, which ensues in airlocking the head, boiling it over and your engine bay turning orange.

Since this engine has taken a lot of abuse, it was the test engine for the VNT setup, it's had allsorts thrown at it, it leaks like a sieve, the cylinder head is now screwed, I've had the turbo off 12 times on it, so henceforth all the thread holes for the manifolds are screwed!

I've been umming and ahhing over what to do, do I even continue with the XUD - as a good friend said to me "If you spent as much time and effort on a 2.0 Petrol as you do on your Diesel you'd be making 500hp by now..." Which is kinda true, but I really don't care, it'd have cost 5x the amount - I've decided to stick to the XUD9...

So...

New engine time... I've currently got a 102k mile DHY block sat about, it's all in fairly good condition, I've not really had the chance to strip it down and look at the condition, but it's going to have a few bits done to it and hopefully sort my engine out for good!

The (hopeful) spec:

- 1905cc XUD9TE DHY - Honed and Re-Bored
- 8v HDi Conrods + HDi Main Bearing Shells
- Re-Ring pistons and slight skim of pistons to reduce compression (sorta 0.1-0.3 range)
- Thinnest gasket I can get to reduce risk of blowing - Genuine Victor Reinz, naturally...
- (Possible - depends on cost, I'm getting wildy fluctuating quotes) Ceramic Coating on piston crowns, exhaust valves, exhaust ports and possibly pre-combustion chambers to keep the heat away from the head and in the exhaust gas.
- Balance the engine
- Lighten Flywheel
- Decent fecking clutch!!! Probably a CG Unsprung 4 Paddle
- Uprated Head Studs - 12.9 heat treated and Stud/Nut...
- Front mounted Intercooler - finally - with proper hose routing.
- Modified inlet manifold - proper plenum inlet, partly to not have a Xantia Lunchbox and partly to enable better hose routing.
- Re-install oil cooler with new radiator.
- 100% Not decided yet - completely cash dependent - Bigger turbo, maybe a GT2056V or a GT2256V - but that's only if time and funds allow, if funds really do allow, then I'd love a GT2260V.
- And another funds related maybe - bigger coolant system radiator - the stock ally one really doesn't take prolonged ragging.

I'm not really looking for more power as such - maybe it'll push up to 185hp, just a more consistent power, remove a lot of the unpredictability of the setup as it is at the moment, it's like a hormonal, menstrual woman at the moment - mood swings all over the place. It'd be nice to know when I need to overtake something, I can mash my foot into the shag pile and it'll go the same as it does every other time.

Go Team More Shitty Diesels!!!!
