M50 intake on M52 engines

[cop]

I've heard about this mod, but it's a good idea?

[midtown328i]

Very good, good gains to be had.

[cop]

How much gain?

[Tochenzo]

i heard it's like 20hp gain, but you loose some low end torque

[NSM]

This mod is great for some HP up top. You do lose a little torque down low though as stated above. Turner Motorsport offers a cam kit with his manifold for a decent price. Doing the cams with the intake manifold at the same time is a good idea and you do not lose any noticeable torque.

After the mod I need a custom ecu.

No you don't software for it will makeup for the loss of torque in lower rpms, but it isn't necessary. M50 intake manifold with M3 cams and custom software will create more power than a stock M3

My car is a 1995 e36 coupè with a M52B20 engine euro spec. it's 150hp, I need a 325 or 525 M50 intake, right?

i will agree with everyone else this mod is excellent. My 325is has the m50 engine and it's amazing. If your going to be installing new cams you might want to replace your headgasket with another oem one and clean up your piston heads, and maybe even check your fuel injectors.

If I was doing this mod I would do this
-m50 manifold (www.understeer.com)
-Schrick Cams (www.turnermotorsports.com)
-New oem headgasket (bmw dealership or any euro car place)
-Custom software (www.turnermotorsports.com)
-21 or 24 lb injectors (www.turnermotorsports.com or www.aatunning.com)

Your looking at approx 50hp gain right there, and you'll have good hp up top (m50 manifold) with torque down low (schrick cams). The injectors will give your better throttle response, and turner software will give you the ability to fine tune it all together. To top it all off i would also invest in a cai. With all that you'll be rollin faster than stock m3s.

A lot of people have had problems with the m50 manifold conversion though so I would suggest buying a complete kit from understeer or turner. If you search you'll find the problems others had and how they fixed them.

Best of luck to ya!

Thank you very much.

[swoop]

To answer your question if you call any of those places they'll make sure you get the right manifold on your vehicle.

[cop]

Do I need to replace the throttle body?

[Silverstreak328]

No, if you don't get teh eurospeed kit it is much harder to install. I have done both and with teh adapter it takes half as much time.

[cop]

Why the use of large injectors?
