I'm thinking of acquiring a 156. However, I found that 2.0 TS is more agile but 2.5 V6 is more powerful. Do you guys think a modified 2.0 TS (ECU, CAM) can have similar acceleration as 2.5 V6 but better handling?
You can probably get very close or exceed (turbo from autodelta) the performance of a stock V6 with mods. Depends on what you're looking for from the car really. I enjoy the characteristic V6 howl so I'm biased New cams and a remap would take you to about 175hp. Do the v6 mod on the intake and perhaps a better exhaust and you'll see maybe 185hp. Which would be more than enough to equal a v6 due to the wieght difference. However you will have spent around £1500..... I'd get a v6 and sort the suspension and brakes out instead.
