Its a short runner EFI intake manifold called single plane that can use a 4 barrel throttle body, the manifold has fuel injectors and rails. Identical ones are made without injector holes for carb applications. It is just another style of intake.

Carb and coil on plug has its places. You can run more ignition timing and higher intake air temp.

Cool deal keeping the 6mt and awd.

Nice crank damper.

The torque curve has to be fun, no turbo lag.

Not "hating" on the swap, just don't act like you're improving on anything other than parts availability. I live in the south where LS engines are all over the place, and yes they do break in stock form. They have their quirks as well.
Will have specific numbers when car is finished.
What you can get away with on LS engines is surprising. Cost, power, weight and reliability is the reason it is a common engine swap.

I agree don't do random numbers. Don't forget the intercooler.
Weight difference between bare long blocks is ~140lbs but that is not a comparison. Apparently its less than I thought.

Thank you. The Audi is similar but their v8 is more compact. Still LS swaps do happen with AWD in audi cars.

It was an option but Subaru no longer produces new blocks or crankshafts for the EG33. There is a limited amount of these engines left and that means either expensive or poor condition.

The EZ30 is cheap and more readily available. Either H6 also require a rework of the exhaust, cooling, and electronics but you don't have to cut the hood or use a transmission adapter. You are limited to motor mounts from an H6 though.
