Thread: What happened to your Discovery 2 today?

Yeh, sorry, V8.
I’ll take V8Ian’s advice I think.

This last week a few things ticked off the never ending list...

Changed the engine side heater hoses on the White one, also installed a catch can (had to reinstall the turbo heat shield, bit of a mission in itself) continued working on the switch panel and wiring for the sub tanks and pumps.

Also clocked up 700km with the V8 torque converter and reco'd transmission, still amazed how much better it drives.

Did a basic service on the Red rig, just spin on oil filter, oil and general check over.

Off to pick up another V8 converter tomorrow for the Red rig. Planning on installing it later in the year when the young bloke goes off to Japan for a couple of months, might refresh the trans as well, not sure yet as it's driving quite well

Cheers

Hey Redd, which parts have you used for the conversion? or where from?

Also, are your Td5's standard or what upgrades?

It sounds like you think the upgrade is worthwhile!

Morning Slunnie,

I just used the Ashcroft adapter kit, the trans I got from Discorevy he managed to find a converter for me. The TD5 is stock tune, I have wound up the waste gate a bit but that's about it. Off the mark it's a bit doughy but once you get about 1800-2000 rpm it just boots along, a tune will sort that though. Yesterday I picked up another converter for my sons Disco, heading from perth out to Toodyay there are some long hills, it was great being able to just ease the foot down and pass trucks without thrashing everything, it pretty much just held the gear and pulled like a modern diesel should.

As Discorevy said, if they had of come factory with this converter, sales of the V8 would have been non-existent.

Obviously the biggest issue is having to drop the transmission to complete the installation (mine was showing a lot of wear, even though it was working fine 380,000 kms on it) if you need to drop the trans for any reason (rear main etc) I'd definitely install the converter while you can.
The guy I got the converter from said he had done his and he is also running a VNT as he tows a horse float and needs the boost/power off the line a lot more.

Sorry, I know I sound like a fan boy but for me it has totally transformed the drive. My wife drives a 2015 Prado (last of the 3lt) it has a 5 speed auto, honestly they drive very similarly, not reving the daylights out of things which is how the Disco felt

Also, even though I love putting the boot into it now and enjoying the torque of the motor, yesterday I clocked 550km and used 61 liters, I was s expecting much worse as lots of hills and pushing along as had time frames to keep

Cheers

Mine had another serious overheat event. Could be as simple as the viscous fan, could be the HG. Don't think it's the cooler because there is no water in the oil.... Seeing as the rear main is probably leaking I guess I might as well pull the engine out. So, where do I get a V8 convertor, and do I need the bell housing too?

IIRC, you just need a converter, and the adapter kit from Ashcroft(or wherever).

From the info on Ashcroft, it's also better to create a new access hold in the bellhousing(std TD5) to get to the differently located bolts(4 instead of 3) on the V8 converter.

@ reddirt ... you say it's better, that you just boot into it, and it moves along, no fuss, no thrashing, etc. Did you just install the V8 converter? No V8 trans ECU?
At what RPM do you get converter lockup, etc ... ?

My D2 and D2a.

D2 I fitted the V8 TCU I had from my spares bomb. D2 has a tune(I think from TRS, that I can see). Always felt very thrashy, especially around town. By that, I mean the TD5 has really good torque, and the TD5 TCU would never allow it to lockup or change gear early enough to make use of the 'tuned power/torque' .. so it felt very thrashy. I installed the V8 TCU and everything changed, for better, worse then worse again. All changes much earlier 60k/h lockup in 4th at about 1100RPM. Normally don't drive like that, but still good torque for around town and some slow dirt tracks. I usually drive it in 3rd at 60k/h and also locks up and usually about 1500rpm(give or take on all rpm numbers) this feels the most ideal. Problem was cruise control went haywire(Shack fixed that for me ... awesome Shack). Before fix was close to unusable. Then the 'worserer' problem started. TD5 converter is not up to the task of low rpm lockup. What happens now is that at low-ish RPM it has this initial slippage(and accompanying vibration). T/C is not slipping as such, like a worn converter, it just slips at the initial part of the torque increase and pedal demand. It's easy to moderate so as to not slip/vibrate .. just annoying. No slippage at higher RPM. eg. at 80k/h 4th and lockup any pedal more than say 10% will cause slippage. same speed in 3rd and locked, any amount of pedal will not cause this initial slippage issue.

D2a is stock everything. Original TCU was montrously annoying by comparison. I live in rural Vic, any drive more than 2klm is highway here. D2 trans is near perfect in operation(other than initial slip problem) but D2a is most annoying contraption ever. Pretty much every drive engine is screaming like mad on the 99.9% flat open highway, what feels like hours. Absolutely no need for it, but this is the way it works. Maybe 10 mins minimum, it's screaming at 2500+ rpm until engine coolant hits its required temp .. then finally it locks up and drive nicely. But those first (whatever) mins is hard to get used too. During winter we get quite frosty and this makes it even worse. Original D2a TCU was worse again, I fitted the TCU out of the D2 for now which helped by a percent or so.

Planned on doing that regardless. I'm no obstetrician.

Thanks, I'll check the Ashcroft site. But I guess that will make my upgraded flex plate redundant.

Yeah, triangular 3 bolt flex becomes redundant. The Ashtrans kit has the round 4 bolt flexplate.
