X51 3.8L with or without the 4.0L stroke would not make or break a targa stage.
Porsche offer the clubsport bolt-in roll bar for those who wish to rally or race their road registered vehicle. This would allow you to run a GT4, GT3RS or GT2RS in a tarmac rally. Porsche is one of the only manufactures to offer this. So even though their mandate is to sell competition cars for racing and sell performance cars for street, they still have motorsport options for the GT cars.
(You should be able to run Targa Newfoundland and Targa New Zealand with a GT4 clubsport or Cup car. However Targa Tasmania require road registered vehicles.)

You could take a street GT4 and develop it with Clubsport parts depending on the class you run. Clubsport motorsport parts would be brakes, aero, doors, seats etc.
PDK would be the only thing missing which would be nice to have for competition.

At least for the US, the mount points needed to install the CS roll bar are missing from the GT models.

tcsracing1

Indeed, north american cars do not come with the mounts.
I suspect Groundhog is in a country or a position to run a tarmac rally therefore being from outside north america.

At best, the additional torque of the 4.0 would have been due to the additional 200cc of displacement and its proportional increase of 5% across the rev range. At worst, there would have been zero increase in peak torque (because the gearbox for the GT4 is already at its maximum torque rating of 420 Nm or 310 ft-lbs), since Porsche would likely limit it. Pretty hard to feel a 5% difference anyway though...

MOBY DICK IS BACK!

Yep...there was the sighting of a great white whale!

Ksdaoski

77 of them
Should be easy to obtain

Have the rennsport app but nothing showing . Thanks for the link

Sweet! I got a pic with Moby Dick back at RRIV...leaving tomorrow morning to see this bad boy in the flesh!

Totally dependant on state of tune and it would be going in circles round a GT4

The only interest I have is they - laptimes - show/highlight the performance characteristics or lack thereof.

A small proportion of us actually use our cars in a variety of competitions and therefore have somewhat different views to the DE crowd.

My expectations are simple - the base is fit for purpose - based on the current information, the proposed 718 GT4 does not meet my needs nor does it match my expectations.

I'm not interested in deviated stitching or PTS I'm interested in a robust engine with good mid-range and top end mated with a good reliable dual clutch transmission sitting in a nice rigid chassis with well sized braked - a good starting point.

The GT4 should be this car, it could be this car, but it wont be.

Not exactly...
State of tune is funny comment. Cosworth would be a race motor on race fuel... With rebuild intervals. You dont go out a beat on a cosworth for 9000 miles of racing... not one that can run "circles" around a GT4 anyhow....
GT4 is a street production motor. You throw them away and stick in a new engine when need be. Cheaper then a cosworth and desiged to run in "GT4" with other production cars..

tcsracing1

autocross? rally?

Far as I know that is pretty much it for street cars worth talking about? What else would you be into to that require more then what the GT4 is?

groundhog

Not really its absolutely correct - if you run it rated at 600HP and do X hours that changes the timing of the rebuild schedule Vs run it rated at 400HP and Y hours. Cosworth EJ long block ~ 15K and you can run them on pump fuel through to race fuel using flexfuel tuning options.
