In which case those short short block B30 3.3 liter engines are exchange - the heading over that whole section reads "Servicemotorer - Utbytes".

BTW ~$1200 for a 3.3 B30, and about $835 for a 2.2 B20 block - exchange.

I don't know about a 3.3 liter B30 but from experience I can tell you bumping a B20 up to 2.2 liters makes a quite noticable difference in low end torque. I'm not sure how much the HP is incresed, as with a stock induction, head, and exhaust the upper rpm power might not increase as much due to limited air flow.

So to get full effect from the increased displacement you'll need to increase the breathing as well - so a modified head, cam, open exhaust, etc will amplify the increase.

PS - They also sell stroker cranks (80mm stroke to 86 mm) that will add about 200 cc displacement to a B20. Do that AND a big bore and you would have a 2.4 liter B20. That would be a torquey engine!
