Hi, im new just bought an 03 astra van 1.7dti
my last car was a 306 hdi, which i had added a couple of extra bits too to take it from 90bhp up to 160bhp and 280lbs torque.
so as you can imagine the van feels rather sluggish.... im not wanting to make it stupidly fast (unless its fairly easy to do!)
just wondering if anyone could tell me whats needed to get about 120bhp?
and also if anyones gone for more power than this, whats needed etc, does the clutch need uprating?
for the 306 i added a front mount intercooler (didnt have one atall as standard), adjusted the turbo to 23psi, straight through exhaust, and a custom remap, then i needed a £360 clutch to handle the torque! lol
what sort of gains would i be looking at from fitting a bigger fmic and can i get it remapped?
iv heard alot about tuning boxes on here but want to keep clear of them and prefer a remap.
is the turbo wastegate controlled by the ecu or is there a wastegate adjusting arm on the turbo?
any help would be great
