M20 or M50 ?

[Overlord475]

Unless you're going Forced Induction I think an M50 is a wast of time.... Yes, they have better head flow than an M20, but you won't feel much of a difference.

If you're going to swap in an E36 motor I would suggest at least a S50B30US, they're already OBD1 and if you can find one at a good deal they can be cheaper to swap then an M52

A fun swap to do that is less expensive than an M/Sx motor but will still give more power than an M20 is a M30B35. They're produce more HP than an M20 (yes they weigh more) and are great for FI...... someday, when you have more funds.

That's what I'd do on a small budget.

I know everyone hates the "what am I missing" but I read a lot of stuff and just want to make sure I didn't forget anything major, could someone check that list? Thanks!

• M50B25
• E34 Oil Pan
• Oil Pan gasket
• Pickup, Dipstick/Tube
• E36 Engine Mount Arms x2
• E28 Motor mounts x2
• Oil Pump gasket
• GetRag 260
• Trans brace from White325is
• M20 flywheel
• Pilot/TO Bearings
• Maybe short shifter kit
• Pressure plate
• Guibo
• E30 Rad
• M50 hoses
• Premade Wire harness
• Stock brake booster, slotting wall

Am I missing any accessories that won't work from my stock E30? Also when I am getting belts to fit the pulleys and what not, they will all be M50 correct? And can anyone suggest a reliable flywheel that's not too expensive.

Anyone willing to look this over?
