Sirius Turbo?

Hi guys, just wondering if anyone knows anything about the G63 Sirius Turbo wide block motors? I pulled a motor out of a mighty max pickup and on the valve cover it said sirius turbo. I didn't pay much attention since there was no turbo routed in the exhaust, I just figured it might be a jdm replacement. When i got home to check out the side by side differences of the wide and narrow block, i noticed a plugged oil return pipe on the oil pan. I took off the oil pan and noticed there were oil squirters for the underside of the pistons just like the 4G63T. I also noticed little differences between the two blocks like no knock sensor boss, missing one threaded hole for the T-belt tensioner bracket and missing the two small coolant passage ways that flow from the block to the head. Is this a rare motor? I haven't heard of a G63 turbo motor yet.

Very interesting. I haven't heard of one either. Maybe it is an imported starion turbo motor?

This is the reply i got from mainstream from the starquest forum;

yes indeed it is. Squirters are a definate for a turbo motor. The g63b tubo came in all starions outside of the US. I hope you got the head too. I'd love to find one (whole motor) in a junkyard.

Waaasup mainstream!

. Yeah, switching to a turbo motor without a turbo must have been slower than stock. That motor is pretty clean except for the t-belt tensioner which came apart. I think that's the reason they dumped the truck

Look on my web site http://starion.mrbdesign.com.au see "4G63 SOHC 8 valve" for information on the Sirus engine. All Starions sold in Australia had the "Sirus" 4G63 SOHC engine.

We don't have to swap the 4G63 because we already have one

We just concentrate on installing the DOHC head (typically VR4 Galant head is used) which bolts straight on the SOHC block.
