better daily driver? M20b27 or M40/M42

[CHIF8008]

i love my b27 as my DD

[stamar]

Im very suprised that m42 , a modern dis dohc motor could lose to a b27 m20 sort of an old school 70s tech motor.

I have never driven an m42 but i have driven an eta and it has kind of that vw bus thing going on the onramp trying to get to speed.

before that happens everything is fine. Off the line its awesome.

i was considering a M30 swap until i found out how good (read: terrible) its fuel economy is

[VinniE30]

is anyone else irritated by the fact that there is 6 votes for something else, yet nobody has mentioned what that something else is.

M30
I DD it.:D

^Original gears, chain, rails, and idler, updated tensioner. I don't think there's much wrong with the rails so long as a loose chain isn't beating the living piss out of them.

My father-in-law's m42 has 270k on the clock and his original timing components look exactly like mine @ 117k.

woah, that's impressive. I take it he's replaced the tensioner and actually maintained the car then, haha. The only thing I'd be wary of is the original rails were superseded by a new design that didn't degrade over time, though depending on when the profile gasket was replaced, the rails may have been updated as well.

I daily drove the shit out of my '88 vert for a month.

How can this be applied here?

Also had to DD my buddy's ETA

For what, a week?

I daily drove the shit out of my '88 vert for a month. Loved it. Got great mileage and ran like a champ. Also had to DD my buddy's ETA when my trans went out the first time and despite it not having much power, thing had awesome torque and loved to rip through first and second.

Anyway, sounds like I'm walking on broken egg shells here. Peace.

^Given the fact you haven't daily driven either of these cars I feel that your opinions on this matter are dubious at best.

[e30austin]

^So you've DD'd an m42?

Not daily driven, no. I have driven a friend's M42. Not impressed in the slightest.

That's because you're an ignorant, angry ginger.:D

Angry? Ginger? No soul? Yes. Ignorant? Hold on a minute...

:)

Also, the timing case thing: the timing components wear out between 150k and 200k depending on driving habits, tensioner, etc.

My father-in-law's m42 has 270k on the clock and his original timing components look exactly like mine @ 117k.

I'd drive an automatic M20 car over an M42 5-speed car any day of the week.

That's because you're an ignorant, angry ginger.:D
