It had sometimes confused me why I couldn't get my sidelights to illuminate on their own.

From the forum I came to learn of the dim/dip "feature" and was keen to remove/bypass it

There are a few ways to do it... unplug engine bay connector, use jumper wire, fit LR bypass relay YWZ10003L (£30!!) but I decided to modify the existing relay.

Some steps should anybody else want to do this...

Remove the big pink relay from the board under the steering wheel and unclip the cover from the base

Cut/desolder/remove everything but the two necessary pins - these are the two that remain on the left hand relay below

I managed to source a bigger GT2256 turbo from a 3.2 TDCi

Externally it looks to be physically very similar to the factory 2.4/2.2 GT2052. Manifolds are the same, same hole centres, bores etc. Turbo outlet diameter is the same etc.

Plan is to build a Hybrid turbo by fitting the 56mm compressor side from the 3.2TDCi GT2256 to my 2.4 original 20mm hot side resulting in a GT2056

The 3.2TDCi GT2256 has a six blade compressor wheel vs the factory five blade

Below are some side by side comparison photos.

Hybrid turbo built up and fitted and initial impressions were not great! But Pete Bell provided me a tweaked map to provide the extra fuel required to match the extra boost and it really came alive. All in all a good outcome, especially considering the new turbo was under £100 and only took a couple of hours to fit. To be completely honest though not worth it if you're looking to pay £1000 for a hybrid turbo

Seams to be leak week

- Leaking AC condenser. Replacement sourced from https://www.ebay.co.uk/itm/363436234249
- Leaking intercooler (Alllisport). Replacement sourced from BAS
- Leaking heater control valve. This will be the third replacement I have fitted. Went for a genuine JLR part this time rather than the cheaper ones available online
- Oil leak spotted underneath... Not sure where it's coming from yet. Have degreased in an effort to better locate the source. Possibly sump gasket or a PAS hose union.
- Cash leaking from bank account. Source suspected to be Land Rover Defender

Really nice work Hank.

How youd finding the darker interior? Doesnt feel too dark inside? Considering the same in mine.

Love the dark interior. It’s one of the less technical modifications I’ve done but it's easier on the eye

BAS intercooler is in. First impressions… Immediate obvious difference in power. The turbo still spools up the same but since the boost is actually getting through to the engine now rather than spewing out of the split intercooler the engine picks up immediately and comes on song nice and low down in the revs then pulls right through the rev range.
I’m not saying the BAS one is better than the Allisport, just saying that having the pressure side of the intake system sealed is a definite bonus Laughing

Also fitted the new heater valve complete with cold temp return spring mod… Works a treat

Great work going on there Hank, liking the new intercooler Thumbs Up

I too had the same problem with my Allisport intercooler developing 2 holes like yours, as you had more of a choice other than Allisport i was not so lucky but in the end i found Airtec and had the choice of colour Thumbs Up Clayton.

Tbf after 3 years in mine my Allisport popped as well, though they replaced it within a few days of reporting it so cant complain!

Good to know about the darker interior. I dont think ill bother trying to recover it, experimented on my 90 and it didnt go well Embarassed it looked ok but not good enough tbh.

So dying/painting is a better option! What did you use?

New condenser fitted today and will regass tomorrow.

I went with one of these ‘aftermarket’ ones - £250 delivered which beats £450 for the OE type. Ordered on the 16th, arrived on the 23rd and without customs charges Thumbs Up these are designed for hotter climates and almost twice the size. Quality is excellent, very nicely made. https://www.ebay.co.uk/itm/LAND-ROVER-DEFE...890.l49286

As for fitting… Not quite a direct swap Laughing but pretty straightforward. Took around twenty mins.

There are fan mounting brackets on the new condenser however they are designed to accommodate a 15” fan whereas the OE fan is 12” - perhaps the AC fan is 15” on the continent?

Anyway I bolted the original fan through the cooling fins the same as the mounting arrangement on the OE condenser. Works fine but I may keep my eyes peeled for a 15” one

Then the condenser fouled slightly on the intercooler, perhaps as my intercooler is aftermarket? So I spaced the condenser forward with some nylon spacers approx 10mm thick.

Finally the aluminium AC pipes were slightly out of alignment but are easily tweaked to suit.

Looks absolutely great, looks like it fitted in well. Would be interested to hear if the performance is improved with the larger surface area. I had aspirations to fit 2 x 12" fans (we have a spare OE fan lying around) by relaying off the first, to give the original condenser more capability as it clearly saturates particularly in traffic sat stationary, be interested to see if this solves that issue the "correct" way instead of just adding more fan capability!!

....sorry one other thought.

It'll need more gas as it's a larger condenser?

Presumably to fill it correctly you need someone who's happy to run the system and then add more gas progressively till the evaporator runs at just above freezing on air egress? Not exactly sure how it works. Just dawned on me that it would be undergassed on the original amount LR put on the sticker under the bonnet.

The seller said “Since your new condenser is slightly bigger than the old one, you need to top up a bit more refrigerant gas.”

I’m not particularly clued up on air con systems but am hoping that a garage will know what to do Confused > 110 XS Double Cab

Was talking to a friend who used to be an AC engineer last night to see if I could work out what the process would be as it seemed a great plan for a defender as they do struggle especially abroad with UK spec condensers.

His advice was yes you could just top up a bit more but that you'd not know what that number was... You could either over charge it and end up with a system that a) trips out all the time, and b) knackers the compressor over time, or undercharge it, whereby the condenser isn't actually doing anything for you it's only performing as per previous.

He said to do it accurately the garage would have to run the system and measure the temp of the evaporator and add till you get to just above the evaporator temp where the compressor would click off.

The logic being when the car is stationary and on a hot day (i.e. the condition it's in when you're doing the exercise) that's worst case anyway. Leave windows open and run the blowers at 3.
