996/997 supercharged V8 conversion
Discussion
Ok, I know this is a can of worms for some Porsche owners......but...
I am keen to purchase and convert a 996, or preferably a 997 2dw non tiptronic or PDK car to supercharged chevy power.
I realise some will say why not go Porsche turbo - and I kind of agree bar the price. Plus ultimately the Chevy unit should prove cheaper to run/maintain, and of course it has a V8 soundtrack to boot.
Has anyone carried out this conversion? I am currently looking at Renegade hybrids conversion.
I am also looking for the right car, preferably with mechanical issues or a borked engine, so if anyone can help please contact me.

I once raced a 911 for somebody who had fitted a Cosworth V8 engine in it (or rather on it). The centre of gravity was far too high and the resultant handling issues made it uncompetitive and a real handful to drive. I understand the economic attraction of the upgrade but my experience of fitting a V8 in a 911 was not positive.

I suppose that's one of the big benefits of a boxer, lowering COG.

But then, you will have nowhere near as much experience as Mr.Rance in driving race cars.
So what? Neither will 99.9% of drivers. OP doesn't mention racing either.I'll try and borrow a stock 997 and compare back to back with Angus' to see how they compare. Old cosworth V8 is very different proposition to a LS though.
From a drivers point of view the handling of the rear engined 911 is primarily resolved by the low c of g of the boxer power unit. It allows control of the car in the initial braking phase, a trail after turn in to counter understeer and an early throttle application on apex. We couldnt get any aspect of cornering to work with the V8. Later 911's have a longer wheelbase which will help slightly. Overcoming roll oversteer on turn in and on throttle on exit along with settling the rear under initial braking will be the challenges. In normal conditions of grip on the road, you may be ok. When looking to deploy power or In conditions of low grip ie the wet, even on the road the effects will be more pronounced.
Interesting challenge. I'm sure that the conversion will include some suspension/diff upgrades also

I have an early 1998 996 manual with a blown motor that could be for sale......I am keen to purchase and convert a 996, or preferably a 997 2dw non tiptronic or PDK car to supercharged chevy power.

Get on and do it,you can dial most issues out race or road.what would be usefull is a short gearbox and bell housing,get the engine as far forward as you can,and as low,some of the ali block v8 are not much heavier.
What you could look out for,is a short Spyder/cup/rsr gearbox,that would help a lot,sequential all the way!
Mclaren have two very nice 911 with the tag turbo v6 in,used as test mules,they handled ok even with 1100 to 1500 bhp!
