Timing Belt Party / Check - In

[Roland H]

I tried to get a 318is the other day but it sold right away, otherwise you would only have one S52. :)

Ah, that's a travesty. Let me know if you find another. ;)

Megasquirt + V12 will be three bitches and a half. We'd have to run 2 EDIS-6 systems (we can use one trigger wheel though), as well as two MSII ECUs. At that price point, we need to evaluate alternatives. I'm not sure if the M70 has a cam position sensor, but I'm pretty sure that the M73 does, which means we can run fully sequential ignition if so desired...

according to the guy who runs DIYautotune, it's possible with just one Megasquirt. I'll need to call him and make sure that the intarwebz didn't just lie to me, but I'm pretty sure it's simpler than a whole shitload of MSIIs. MSIII might also work.

I do have a pinout E30 V12 diagram, so if we have to use the stock engine management that's possible too.

Ya that M73 dyno isn't the best comparison, but it's still impressive. For bolt in shenanigans, the M73's hard to beat. Noone makes parts for it though.

Roland, do you have the brakes and suspension from the dead M3? Cause....GRM 5 lug would be wicked.

Also....i can s52 haz?

Interesting. Ask him what was used for ignition. If we have the option of using/retaining sequential ignition, I want to do it.

For starters thats not a bad idea, however, if we plan to mod the thing, we need something that *we* can tune or get tuned locally for cheap.

Yeah... any info on the shricks for the M70?

I have the rear setup, but it won't work without some serious modifcashun. We would need a 318ti or a z3 rear suspension... Can I borrow your ti Brad?

$2k for everything you need, and I get the OBDII stuff you won't be using/needing.

If it comes back with a S52 why not, heh.

Will do. I need to survive school through thursday, then the V12 research begins in earnest.

Agreed. I don't want to deal with 5 ECUs.

Yea, +15-25hp or so on a bone stock M70. Without tuning. However, due to the 8.8:1 CR (M73 is 10:1), those gains would be a shitton more if you get high compression pistons. They'd have to be custom, but VAC I'm sure can figure that out.

The best cams come from powerplant racing, who do a roller conversion. They are the only option for the M73, and I don't know the cost. The roller conversion is $1500 (on an M70) without cams.

The M73 would be the best candidate for bolt in power, as it makes 326hp and 361ftlbs stock (torque matters for autocross much more than power), but tuning options are just about none. I think those heads flow better than the M70's.

I could go on, but i have to run to thermo. I'll revisit this after Stats midterm.

Maybe. Just maybe.....need to figure some things out.

BEN BUY THIS!

Yeah, I'd *like* to do the M73, but it all depends on costs too... ;)

S52 and no suspension sound fair?

[blefevre]

I wonder if I can do a 4-lug swap to the Ti? Then I still need wheels for the E30, damn, viscous circle!

Do it!

Probably would be the only 4 lug E36 around.

huh huh, you said "viscous".....

[blefevre]

Whoops, too much engineering in my head.

[Bimmerman325i]

hahahahaaaaaa


viscous.


Roland, you coming down for the Tbelt and Euro Bowling Shenanigans?
