i disagree.
most petrol cars peak power is between 4-5k.
only worked cars have full power at 7k rpm.

Just a side comment - Is it just me, or is the Roverworks page unusable on an iPhone??

Yep, it's pretty poor. I can't zoom without the page header filling the screen....

Does anyone have experience-based thoughts on whether modifying your Defender makes it more reliable, less reliable, or no difference?

For examples:
Assuming that workmanship is solid:

- Is a chipped engine with a bigger intercooler and a custom exhaust that adds 20-30 HP any more or less likely to conk out than a stock motor.

- Or is a 2" raised suspension with the camber also sorted any more or less likely to give problems than stock suspension.

- Or are upgraded drive trains more prone to niggles than stock ones.

- Or is a Defender with holes drilled in it for wing protectors, roll cages and various other add-ons any more prone to rust getting in.

Changes or upgrades to a Defender don't seem the same as hotrodding of other vehicles, since they are usually done for a functional reason - to increase the number of places they can go, survivability etc. The hotrodding mindset that I see with owners of my other brand of vehicle seems to lead to more problems in general, although it's close.

This is only my opinion,but;
Forget add on chips and only go with a reputable tuner and use only BAS or Alive to re-map the ECU.High flow exhaust is questionable as it reduces back pressure and can affect turbo operation.Bigger intercooler provides big improvements,and consider blanking the EGR while remapping.
Two inch lift doesn't sound like much but you're probably looking at DC shaft.No camber adjustment on these but castor can be affected but correctable.
From what I read on this forum any improvement to the drive train is a good thing.Have a look around the site and you'll find a lot of interesting threads.
Regards to drilling holes.
Apparently stainless steel and aluminium in contact create a chemical reaction ,causing corrosion.So avoid using the two together or use a chemical agent between the two.Someone will fill you in.

Cheers - this is a useful reply.
