my defender has the overfinch gearing and chip. it does go like stink off the mark but runs out of puff at around 85-90 whereas my standard 3.9 rangie will pull to 100 no problem and on to 110 if you've got a road long enough (maybe an aerodynamics thing Confused)
I'd certainly deal with ashcrofts, they know their stuff better than the jack of all trades when it comes to gearing.
Koni shocks are spot on at reducing roll as they don't want to extend like gas charged shocks. Personally, i've got old man emu springs and shocks with the anti-roll bars removed purely to improve off-road articulation, but it doesn't roll. These springs are solid and i'm very happy with them. My range rover on the other hand pitches and wallows with its born in the usa scorpion springs. Great off road, but severley compromised on tarmac.
rpi engineering are worth a look v8engines.com. so is lundengines.co.uk and j.e. developments (not the other JE) at rover-v8.com. Lund will carry out mods on your engine, whereas the other 2 will only supply the bits you need. RPI will supply and install a brand new engine. Add 2 grand to there engine price to include fitting and chipping. They use mark adams eprom chips. Don't bother with anyone elses chips.
If it were me, i'd start with the gearing and exhaust (janspeed have recently manufactured one for the 50th). See if you're happy. If not, the mods you've already done are still good, then decide either to uprate you cam, heads and eprom mapping, or get a bigger engine. If you chip your 4litre, and then decide to increase engine capacity, you'll have to chip again (another 750 quid!)
If you've got 12 grand lying around, that'll cover a 5.2litre with biggest valve heads ported inlets, tubular manifolds, superflare trumpets and twin plenum intake. You'll not need a gearing conversion with over 400lb/ft of torque Razz
Bear in mind, if you put a chevy small block engine in from overfinch, no ARC club member will buy your landy, as their rules dictate rover engines only.

Just a little bit to report back from me and Jeremy meeting up and comparing 50th's.

Jeremy has Overfinch gearing and chip where as mine has a boug warner chain drive box and mark Adams chip. I would say there is a small differance. Mine holds onto the gears for longer, and i think chages down more gears when you boot it, i.e down 2 gears not 1. Also Jeremy comented he thought the transfer box wine was alot quieter in mine due to it being chain drive.

Was good to meet Jeremy, his is a really nice guy. He is mad on land rovers like us all, but maybe we dont have as many as him Laughing 4 on the driveway and a Bowler in build.



cooltide what size tyres are you running, could this make it run out of puff? Mine will carry on pulling past 100

Best regards

James

Just a little off topic, but I was at the Goodwood Festival Of Speed on Friday.

They had the Bowler guys there giving rides. I think they had 4 wildcats and a truck.

One of the wildcats had the 5.2 V8, 2 had a 4.5 V8 and one "just" a 4.0 V8, although this was heavily modified. I had to have a passenger ride in the wildcat, and wow. Mr. Green If you ever get the chance to go in a Bowler Wildcat, driven by a professional, at speed, off road, jump at it. Absoutly astounding.

Can I ask you guys that have tweeked your 50ths - which of the mods have you had to (or chosen to) declare to your insurers?
Suspension?
Gearing?
Chipping?
Exhaust?
Or everything?
And if so, what effect did this have?
(I'm currently paying around 300 p.a 36yrs old, 9yrs no-claims, 8K limited mileage on a standard car). Anyone do better than this?

And it would also be interesting to know who you insure with/would recommend... as it's quote time for me again...?

And to re-cap a little - for anyone wanting to improve a standard 50th's performance, but running on a tight budget (hence my question on insurance before I spend any more money) - would you agree that this is the order to do things:
1. Gearing (just the tranfer gear, or BorgW if you can stretch to it)
2. Exhaust
3. Chipping
(Or 3 then 2?)

My aim is just to make it more pleasing to drive, in terms of acceleration & then keeping the pace up hills, without having to go up & down the gears the whole time. Rolling Eyes
Thanks, Ads.

Ads,

i would say Chip then exhaust. The chip should give around 15bhp more and make it nicer to drive and the exhaust probally less and not make it any better to drive.
The exhaust will cost more to do than the chip also, if you do if properly, ie tubular manifolds, free flow cats.

Riding in a Bowler is great ! I have one of the originals built from a 2 door rangey using its chassis and powertrain-now having a powertrain transplant to 50th spec with b/w t/fer box and 50th loom.
I used to navigate in comp safaris and hillrallies for a friend in his Bowler. Many stories to tell such as doing a 180 on the side of a welsh mountain and being saved from plummeting hundreds of metres by the only tree for 200yds ! Not been in one of the new ones as seen on Top Gear but followed one for a number of miles listening to the 5.0ltr v8 burbling...heaven!!!
Check out www.bowler-offroad.com and www.tomcatmotorsport.co.uk.

If you like the sound of a passenger jet powering up its engines just before take off - then you'll like a 50th with Borg Warner chaindrive t/fer box on acceleration from standstill(a washing machine approaching full spin was another description).Or a standard t/fer box on deceleration up to a roundabout is like a plane landing !!

So now I'm confused on the B/W issue - better for the 50th or not? Confused

Does no one want to comment on insurance implications then??
Take it everyboby has some - or are you worried incase your insurance people are reading this? Laughing

Adam,
Sorry if weve confused you.
Basically(???) if top end is speed,acceleration and long distances are your priority then the Borg Warner box and R/R size tyres.

If cost comes into it then stick with standard t/fer box and have the gears changed. What stops mine from going quicker is the ecu shutting fuel off at a certain speed (famous ice cream) due to rating of tyres.Yet these same tyres are fitted to isuzu Troopers and they can go past the ton according to someone i met Wink

Insurance: I'm with the NFU and know that it could be cheaper.I received a phone call the other week telling me it was going up by 100 due to the engine performance mods carried out on it. I was a good boy and told them Razz Uprating of brakes is seen as a plus and therefore does not incurr higher premium. I have got to sit down and ring round. A little bit of bullshit on what other quotes you've received can help reduce quotes !!
Try the specialist people who advertise in LRO etc. If mileage is going to be low this will help. My 101 GS cost me just over 90 fully comp on limited mileage and they asked me if i wanted it on direct debit !!!!!!
Hope this helps?

Thanks for that... it's a bit clearer...
Top end speed is not too important for me, if I needed to go fast on motorways I'd have kept my merc! I just would like it more if it could keep a speed of 75mph up the long motorway hills, with a bit of grunt to pull out into faster moving lanes when I need it.
Then also for the majority of it's life spent on A,B & unclassified hills, not to be embarrassed by super-minis!
I am happy to keep the standard BFG ATs as they look the part, and won't let me down in the mud & snow of winter, so don't mind being limited to 99!

I should have taken the chance to come over & see you and James when you met up, and seen the difference for myself, I'm deeply intrigued to know just how much better it could be - let me know if you're planning meeting up again soon? (Can't make Billing though - need to check if I can make the LRO show at Malvern, that may be a chance if you're both going?).
