Installing a 3.2 or 3.0 Engine... Options

[Biggles]

Hi All

looking for some advice from those members who have installed either a 3.2 Carrera or 3.0 SC engine.

Trying to gather information for my conversion but the consensus of opinion is one of the following:

3.2 Carrera
standard engine with 40 IDA3 Webers - will they bolt on and how much adaption work to the manifold is required? Heard the port sizes are vastly different ?
915 magnesium case gearbox with a aftermarket gearbox mount - is Patrick MS the only one who does this?
SC flywheel required to suit 915 box?


3.0 SC engine
standard engine with 40 IDA3 Webers - should bolt straight on with no port adjustments?
915 mag case as above or early 911/01 gearbox with standard 914/6 rear mount. intermediate late required for 911 gearbox ?


I definitely want to go the route of 40 IDA Webers but don't want to track the car, so not looking for top end speed just low to mid-range. What chokes have people put in for this application and how does it drive ?

Sorry, lots of questions !

thanks

Chris

The 40ida's are good for the 3.0 but on the 3.2 you may want the 46's.
Both engines would need the proper size/port manifolds to mate to the heads.
Both would take a flywheel kit from PMS or KEP to run the 901/914 gear box.
If you want to run a 915 then you would need the flywheel & clutch kit from a 3.0.
Then convert the 915 to a side shifter with a kit from Wevo or Martin Bott.

As for the chokes/jets to use on the 3.0 I need to locate my notes.
You will need to have the distributor recurved for the carbs.
