Winter engine rebuild project

[b930]

Cheers, I may have been a bit premature in observing slower boost onset as I had a persistent problem with a hose blowing off. It's sorted now but can't run it till back home from Thailand. Still trying to work out the real women from the lady boys...not as easy as I thought😁

Don't think I would go back to a 0.82 hot side after feeling the engine pull at red line with the twin scroll big housing, it's just too good...feels manic. I thrash it whenever I drive it as its a weekender only so I have no problem with the trade off, feels like a much torquier motor all round anyway with higher comp and twin plugs so even though boost is a bit lower, it still tractors very nicely at low engine speeds.

Brian, thought I had the 42mm headers??? When I ran them on stock heads I had to open the ports up and I'm pretty sure they measured 42mm but I'll measure them when I'm back home. Beautiful things those headers👍

Motor is very zippy and fast to rev with no load as can be seen, feels super sharp. Not that that means too much to the way the car actually drives but it gives some idea how responsive a worked 930 can be, some improvement down to light clutch but most to light rods and pistons. Would make some of my NA cars blush.

What muffler are you running, it sounds good but not too loud?

Its a 3" dynomax, 3" in at top left and dual 3" out either side at the bottom. Its full 3" internal (basically like a 'Y' on its side). Home fabricated, sounds great.
