M30 Intake Manifold |
|
|
I've seen the intakes from BMP and BavAuto for late models. I was wondering
if there was something better for the M30 ('86 535i). I'm not talking about
the filter mods, but the actual intake manifold. Maybe something that
doesn't cross over the head. Has anyone retrofitted a newer hotfilm/wire air
mass meter to the earlier M30?

You have an E28 535i. What you want is a Dinan intake manifold:

At $900 big ones, it ain't cheap. But, its what you need.... |

What is the point of putting a performance intake on a M30 motor? You will
still have only have 2 valves per cylinder, that weak camshaft and valve train
and too many other issues to list to ever allow this motor to be able to get
out of it's own way.
If you want any performance, you need to start with at least an M50 motor.
This is a 6 cylinder car that still has an ingition cap & rotor. Your options
are severely limited.

An M50? You're kidding right? That engine has only a 2.5 liter! The M30 with
its 3.5 liter (ah, that's 1000cc bigger) puts out more horses ( 208 hp stock
vs. M50 189hp - both US versions) and more importantly, more torque (225
ft-lb stock vs. M50 184 ft-lb).
However, I will agree that adding performance parts, outside maybe a chip,
will probably not make your car that much faster. If you really want more,
save your money and get an M5.... |

JRC702 obviously doesn't know what an M30 is...
Having rebuilt an old 3L M30, I know that a mildly ported head and
stainless steel headers will give you an easy 30 hp and some torque.
It's quite possible that an intake manifold will add another 20 or so.
A total of 50hp (easily doable with those options IMO) is much more
than you will ever get from an M50 (and I have an M50B25 in my '91 E34
so I know what I'm talking about, here.)

You could say the same thing about the V8 in a Corvette. Alpina
managed to squeeze 260 bhp out of the same engine just with intake and
exhaust tweaks. So I really have no idea what you are talking about -
clearly you're not very familiar with the M30 engine family, or indeed
the general concept of tuning engines of older designs.

The two-litre version, perhaps? Mm, that's a real torque monster :). |

Just chipping and M30 adds at least 25 hp (i think). My buddy put one in |
his E34 535 and it easily pulls my E30 325is down the straights. It
pulls me just about as well as an e36 M3!
