It's when you suck a bunch of crap into your engine through your cleverly unfiltered air intake and it rattles around in the cylinders.

On a 944 its when the geniously designed cylinder walls decide to separate from the other part of the block. 996s can do it to. It's called the Porsche shuffle. (Luckily I have a 3.6, which doesn't really know how to do the Porsche shuffle)

T70 on a miata....

.... with 305cc injectors.

And a mildly crappy piggyback for tuning.

What could possibly go wrong?

As long as they're not using a manual boost controller and keep it to less than 6-8 lbs, nothing tooooo horrible. But still.... to quote another forum... "Aids"

As a guy who's never gotten into turbo's, why is this setup so horrible?

With a turbo you need to balance compression with air flow, fuel flow, timing and octaine (among other stuff) plus, as shown, there's nothing to keep the engine and turbo free from debris. (no air filter)

In reply to noddaz:

I'd guess poor tuning managed to blow the skirts off a piston or something like that.

On a Miata it could just need an oil change to make the lifters happy. Or.....dead.

AKA, a Mazda BP 1.8, same as the 94-97 Miata. More or less, anyhow.

It's the less that I worry about.

It's no less. Same motor. Actually probably has a MBSP, which didn't make it into the Miata until much later.

It's a HUGE turbo. On a SMALL motor. With WEAK rods. And BAD tuning solution.

It's a bad combination.

Without knowing the true sizing numbers it's a bit hard to say, right? That said, this is the kind of turbo a Buick Grand National owner might swap on the hunt for 10's, yes?

It's a T70. It's big.

T70 + 305 + poor tune in non optimal piggy back ECU = Cylinder Rattle

The guy laid out the whole equation for us! Best case it is the hla's rattleing, but most likely it needs a new lump.

You know that thing would have the piss ran out of trying to get that T70 to spool... lol

Right. It might see a couple PSI in 2nd. Possibly "full" boost in 3rd.

That car is toast.
