Thread: Why no TDV6?

All of those mods will benifit the stock motor, especially the intercooler.

The intercooler provides cooler/denser air on the induction side, so better performance and lower EGT's

The factory ducting air box to snorkel is restrictive, twisted and varies in diameter from reasonable to rediculas. Replacing it with a constant 90mm tube is a great improvement. One of the members of here "Nugget"sell a kit that is perfect.

Exhaust will mods also add benifit and it is still quite.

It all about making it easier to put the air/fuel in and get the exhaust out.

Very impressive !

I have been thinking Pete's "hy-bird turbo" replacment should find its way onto the shopping list and after those numbers ..........

Does the tune void the warranty? And has Bell sorted out that issue with the 2.2L where things had to be sent back and forth? Whats the latest pricing?

Boost and A/F numbers for that tune would be very interesting.

Best to send him a PM to check , but last time I spoke to him ECU's still need to be sent to him. I have bought a spare new one to make this easier.

He posts heaps on Defender2 and is normally very quick to answer questions. I believe he also did the mapping on the Bowler 90's

A new spare ECU would be expensive...?

Not really! I got mine for 75pounds from this seller. I had it shipped in the UK and then got my family to send it on.

Defender development is, and has always been the minimum possible for the smallest selling vehicle in Land Rover's range - period. The Puma (Transit) engine was Ford's way of achieving this and Tata have just stuck with it. Cheaper than putting in a TDV6. Need to meet the next EU emissions target? Just drop in a slightly smaller engine and send the development team on a long lunch as a reward for their sterling efforts.

I suspect when Ford were reluctantly refreshing the Defender in 2007 they asked the marketing guys whether the Transit engined Defender would still sell and after a poofteenth of a second they replied - "I guess so, it can't make Defender sales any worse." And here we are. At the tail end of the cheapest 65 year development program of any vehicle ever.
