Why build what you can buy? It will end up way cheaper , less time consuming and easier to sell the 320i and purchase a 330i.

Gizmo has done it plenty of times. 325i to 330i conversion though.

That was two tourings if I remember correctly. Why we never got the tourings in that motor still puzzles me.

In that case try and buy a written off car with all the bits you will need. Then afterwards sell the parts out of your car with whatever is left.

Both engines are M54's so I guess in theory they should fit :thinking:
But I agree with what's been said. Not worth it. Rather sell the 320i and buy a 330i. :thumbs:

it might be possible to stroke the 320i to that capacity using a 330i crank,rods and pistons, tuning should be relatively simple with a dastek uniq and most likely running 330i or 325 injectors. however the stock bore on a 320i is 80mm where on the 325i and 330i it is 84mm. im not too sure how well a 320 block will respond to removing 4mm off it however it is an option. my suggestion is speak to Gizmo and racing snake as they both have Experience with the E36 and E46 range of petrol engines. :thumbs:

Rather concentrate on getting the 320i engine back to good health - cannot expect it to perform like a 330i, but, make no mistake, a well running 320i is no slouch!

You will need to change not only the complete engine but the airbox, MAF, intake manifold, exhaust, injectors, throttle body, intake boots, gearbox, clutch/flywheel, propshaft, diff, 330i front and rear brakes, 330i rear trailing arms ect. As already stated, cost wise its much cheaper to buy a 330i with all the right bits to begin with...
You can use your existing engine mounts, wiring harness, headers, sump, alternator, cooling system parts, oil filter housing and all the other bits that bolt onto the block as both the 320i and 330i use the M54 motor. The 320i head has 3mm smaller valves than the 330i head yet they share the same exhaust cam, intake cams are different with the 330i one having more lift.
Your original 320i ECU will run the 330i motor in standard form, its the same ECU for both cars but to get the most out of it have the 320i eprom chip replaced with a 330i eprom chip.
