It's pretty straight forward plug & play fiiting the 916 lump in the 748. Done it to mine & it's now got the grunt i expected the 748 should have had.
All you need is the 916 chip & oil cooler.
Do not forget to consider resale value & insurance implications, some companies are not happy with the upgrade c/n wanted to increase my policy from £250 to £750.
