Is there any chance the plug wires got swapped around? It's hard to mess up the base timing, but the thing still has a distributor and wires... oh.

How's the distributor cap look? Have...

Having looked into it just a little,

there's not much out there....

Just an observation from being around this joint for a while-
I'm not convinced there's going to be enough of an N52 swap market
to interest much of the aftermarket.
Both the engine...

Yeah, I was going to suggest a 3.64 from an M10 318-

the E36 M42 got a 1:1 5th and a 3.46, and that's not bad,
if you plan to do much 70+ highway driving.
That diff from a...

It's been allowed since last season- I haven't gone asking around, though.

Last I looked, Total Seal made rings for the M20-
and while I'm not 100% sold on their sales pitch* I have run their
rings in several engines and they're fair value for money. ...

350 bhp in a 2002? erp.

You'd best get the ZF 320 5 speed or the 370 6- speed from the E46 for that,
and maybe a mid- case diff, some seriously custom axles,
trailing arms from...

Watching the PRO3 crowd struggle, it's supposed to be a very precise measuring device that gives an accurate, repeatable number
that needs to be calibrated internally. As in, the DME doesn't do...

Coming from lots of time spent on M10s, I was also shocked by how rough the M54 headwork is.
It would take a bit of careful testing to avoid making it worse, but there's potential
to clean...

I have also wondered what the 'problem' with the M42 oil pump was. It does increase the amount of crankshaft between #1 crank throw and the harmonic balancer,
so maybe that makes a 6 cylinder crank...

uhhh, this isn't a question- always more, always!

otherwise, why go?...

Reliable?

1 bar.

That'll run forever.

Everything over that will deteriorate faster. By 2 bar, potentially explosively.

When in doubt, trust the person...

[TobyB]

yeah, that's been something of a challenge for at least a decade, now.
Which is why the MAF conversions are so popular, and once you head down that slope,
an aftermarket ecu is only an incremental...

The thing missing from this discussion-

the M42 is disappointing. It doesn't make all that much torque, it doesn't rev to 8500 so it doesn't really make F20C horsepower,
and it has...

The thing is, there are multiple ways to 'value' an E30.
Locally, decent, scruffy drivers show up on C-list or
MarketFace pretty regularly, with asking prices
anywhere from $4-8k A...

I'd disassemble, inspect and reuse your old one before I put a no- name in there....

not on street tires on public roads, no.
The E30M10 pan is what we put into
2002 race cars to help with oil starvation.
