Lots of pics please @BioTriffid. I need to do this on 3 lupos.

Each to their own.

Yup. M12.

I believe its this one you need

Good luck trying to find a laser blue GTI. I think you will be trodden on in the rush by quite a number of members on here.

They have got a gem. Great to see so much work being put into Lupos to keep them on the road. The thread was great

The tdi is great fun with 100hp. I did mine myself with an eBay lead and a map file from blacksmoke.co.uk. Total cost around £60 ?

I have the kit to do this (turbos, injectors etc) and will get around to it at some point but life has gotten in the way since the summer, plus my lupo at approx 110bhp goes so damn well it will be a shame to blow it up excuses excuses..... Have a look here for inspiration: I'm going the gt1549 route 1st as it's cheap but probably laggy before going the preferred vnt route mainly for educational purposes. Whatever you do will need a remap on a rolling road or DIY it with a laptop and some software if you understand what you are trying to do and can interpret the results you are getting. From what i have read crank whip and block flex come into play at higher figures, but that may be 3L tuning which have different block but is something to consider, i'd also inspect carefully and / or renew balance shaft chain drive and oil pump (and cambelt etc while you are at it) before going for this sort of output as a precaution. I wouldnt bother with the intercooler, it's good for way more than the lupo can deliver, invest in smoothing the airflow to and from it and a large bore free flowing exhaust instead. A larger intercooler adds lag too. It would be prudent to assume that by stressing it more you shorten it's life, simples.

The issue is the strength of the gearbox, as 150bhp will increase the torque it will put extra strain on the box especially in the key overtaking ratios 3rd and 4th gear which are prone develop synchro problems in standard form. I'm not saying don't do it the tdi is a fabulous little engine just put money aside every week for the rebuild. I'd move the battery to the boot, the tdi's frontal weight makes it understeer any help you can give it will mitigate against this, enjoy
