Subject: [LML] io-550 vs. tsio-550 differences?

Does anybody know the differences between the io-550 vs the = tsio-550?

So far this is what I have determined:

io-550 8.5 compression vs tsio-550 7.5 compression
different fuel pump on tsio with aneroid and a reference port
different injectors with reference ports on tsio
tsio has a scavange pump lines and turbos.
different exhaust obviously
tsio has wastegate and fancy expensive stuff to control it
tsio has a different throttle body part#

The reason I ask is I am trying to create a turbo normalized io-550 and = I am not sure if I should get an io-550 core and add the tsio fuel pump, = injectors, scavange pump and turbos.
I could also get a tsio-550 core and put different pistons/cylinders on = it. I suspect the cylinders are the same and the pistons are the only = difference.

I also talked with Continental about this and supposedly the throttle = body is different between the two but they could not say why. Only that = they had different part#'s. They did say that something as simple as a = 45 vs. a 90 degree fitting or different color paint can cause a = different part# with their stuff so there is a chance that the throttle = body on the two is mechanically the same. I was wondering if anyone knew = the differences between the two.

Also, which core would likely be the better to get, io-550 or the = tsio-550.

This engine is going on a Legacy so I am comparing the io-550G or N vs. = the tsio-550c.

Thanks for any info you might have on this.

Matt
