a little concerned about the age of the electrics (not a lover of these new engine management by computer m'larky) - my 4 yr old Qashqai variable valve thingy needed replacing after only 2 years from new

To be fair to my engine rebuilder - the problem is he doesn't have any 2.1 parts available, but has loads of 1.9 (he thought he had a 2.1 and he could use the internals for my engine which he had bought as part of a job lot of engines a while back - as my internals (and engine case) are bent / broken & totally scrap - my con rod snapped at 70mph on the motorway so the engine didn't have much chance when it made its break for freedomIan Hulley wrote:hightop ratty wrote:What are the actual (approx) gains in power & torque that are possible using the 2.1 (on pierburg carb) as opposed to 1.9 (on pierburg carb) I know this was asked early on in the post - i've re-read all 24 pages of another thread in the last hour (but it looks like better low end grunt, with more power going up hills, & fewer gear changes to do so - which I guess is reason enough).
There is a very significant difference between a 1.9DG and a 2.1 DJ using the same carb, jet set-up and same timing setting.

Really ? Not exactly a 'specialist engine builder' if he doesn't know that a 1.9DG case IS a 2.1 DJ case ... the difference is the crank and pistons.
Sorry - my post badly worded (originally he was hoping to make the best using some of my engine parts, & another 2.1 engine he thought he had - it had been possibly rebuilt at some stage, and did not have engine number markings).

They do crop up but the age-old principal of 'You snooze you lose' really does apply ... known-good ones are few and far between and very seldom reach the point of being advertised.

I've searched the wiki and forum for this but am finding it hard to search as 2.1 brings up so many posts but no definitive 2.1 engine thread that i can find... I've picked up from this thread that it gives more torque, but im not feeling short on torque having just pulled a fully-loaded hightop up Norway's fjords without flinching. Im building up to changing all the fuel lines, and i suspect this would be an easier task without the injection system? But dont want to mess about with what seems like a great engine without good cause. If this is covered somewhere a link would be much appreciated!
Thanks in advance people
There are very very few specialist VW WBX rebuilders in the uk these days, and "we" know most of them (all 2 of them in fact). Who was it?hightop ratty wrote:(a specialist vw engine rebuilder is doing the rebuild)
