Co-worker is selling his 1987 BMW 325(e) with 105k miles, 5-speed. When I test drove it, it felt was awfully slow. And this is coming from driving a "slow" e46 (325i) and "slower" e36 (318i). Yes, I know it's the "economical" engine and whatnot. But looking into it there was hope yet. That I could take on the task of doing mods/swaps that would 'liven' up the car a bit. The mods/swaps that I wanted to do was: differential swap, "i" cams, "i" valve springs, "i" ecu, "i" intake/exhaust manifold, "i" throttle body, "i" exhaust (maybe), "i" tachometer, and chipping the "i" ecu.
Which leads me to the following questions:
1. Can I do all these without having to drill/cut/retro-fit anything? If so please state what must be done and for what part.
2. Is there anything else that must be done/swapped in order to complete this task? (Wires, harnesses, sensors, pulleys, etc.)
Sorry if this has been asked, I searched and couldn't find a direct answer or "DIY" w/ every parts listed, etc., so just compiled everything here. And if I did miss a DIY please provide the link in the comments. Thanks in advance!
