I'm just jealous that everyone else is going to have shiny new engines, nothing wrong with mine atm though (touch wood), as you say, it had the top end done a while back, and it doesn't smoke, doesn't leak oil much, sounds healthy - lol maybe I should let sleeping dogs lie.

Just spoke to Nick on the Varioram, he says fine on standard engines but tends to be restrictive on tuned cars which mine will be... plus it needs a different ECU to control so would not be cheap..

Any 964 or 993 engine that is optimised to run under 7000rpm will benefit from the Varioram manifold, which effectively means any 3.6 or 3.8 with mild cams and either remapped 993 Motronic or Motec if fitted to a 964 engine. Rework the intake runners and the VR will make a little more top end, as seen on this 9m 993+3 engine dyno result:

I'm not so interested in top end but want and engine with good bottom and midrange..

In my opinion you should not consider anything but a Varioram manifold if your goal is a strong bottom & midrange torque. Ignoring the numbers, just look at the area under that graph above and how flat the torque curve is; nobody can deny that the VR manifold works superbly well up to that 7000rpm limit. The VR manifold will work with a Cup cam, the RS cam or the 9m Sport cam as used on the 3.75 litre engine above.

Update and pics!
Went to check on progress on Saturday..engine is being put back together and should be ready in a couple of weeks.. pics below..
Very slight oil mist on gearbox..
Engine out..
Barrels and pistons in good condition..
Pistons cleaned up..
Heads, barrels and pistons ready to go back..
Heavy duty studs
Heads..
Big end shells were scored so replaced..
Getting there..
Was originally going to go for yellow fan but settled on gold as a little more subtle..will also get the valve covers done in same way..
Still waiting for lightweight tinware.. mine was apparently serviceable so will refurb and then sell it.
