I know I don't expect it to be much.. Being a non turbo engine.

I have heard of people fitting 190 exhaust cams to the inlet side? Or is it the other way around?

The ECU (in standard form anyway) can't be remapped - internal components need to be changed.

When I had my 190 tuned and mapped we used an SMT6 piggy-back ECU.

As I found out after I bought all the bits, there's really no point in touching the cams in the 190. We did end up fitting the Piper 270 cams and pulleys - but it's not something I would do again, think they might make maybe 2hp difference if that on the 190 engine. Don't think they're available anymore, anyway.

One of the most important thing to get power gains on the V6 is getting it to breathe better, too. Less restrictive exhaust manifolds, better air intake system and proper port polishing etc.

Then add on some Bosch EV14 or EV6 750cc injectors (make sure they're 12ohm!) to give you more fuel to go with the better air flow... bigger bang=more power

But on the KV6 it all costs... big.

In total, having the engine rebuilt, new exhaust manifolds, SMT ECU. cams, mapping, injectors, porting/polishing cost me nearly 3k - and the bottom line afterwards? 219bhp.

If you spend that on a 1.8t you'll easily see 270+ maybe even 300bhp.

Oh, and did I mention fuel "economy"? The V6 has never been super economical, but after all the tweaks even driving on a long journey now at steady speed I'm getting around 26-28mpg. Before the tuning it was 32-35 on a comparative journey.

It does sound £%*&ing lovely at full chat when the exhaust flaps open up, though
