250bhp+ is not possible from this engine without doing damage to it.

Realisticly you can part ex it for a 20v version or you can do an engine conversion with the 20v version otherwise its free flowing induction (to reduce smoking) derestricted exhaust, extensive mapping and you will be around 190-200bhp and the 300ftlb. It uses a VNT turbo for a reason, change the turbo and you reduce low down power.

It is not possible to get 64bhp and 75ftlb from a remap alone unless Alfa are stupid....(which they are not)

Both figures I quoted (200hp/325lbft) are flywheel, from the second remap I got from Angel Tuning, when I upgraded to using a BMC CDA. It is definitely not 160bhp, as since I cleaned and re-oiled the CDA (mega-clogged up) I was level pegging in a drag race with a stock 2003 BMW 330D (204 bhp), and I had 100 kilo more of passenger weight than he did, making gross weight about same. He did pull away initially from the line, but I put this down to RWD advantage, I sat "in his blindspot" all the way to 100mph which is what we agreed our limit to be, not interested in going faster than a ton anyway.

I don't want this to get into an argument about Angel Tuning and whether or not you agree with their method of remapping cars on driveway, if you don't believe me on the power thats fair enough, I've driven enough cars to know that the torque on this is over 300lbft.

There's a guy on here with 300 bhp on a 10v JTD, he's also after upgrading the turbo AGAIN! Guess the quest for power never ends

I'll send him a message and hopefully he'll join in on the thread.
