360 "Porsche" Bosch throttle body (0280750474) replacement for Challenge Stradale and 360

This is great info!
Are F430 throttle bodies expensive too?

 

no kidding...why is it so expensive for 360's thats crazy

 

What makes the 360 ones so expensive is they are the only versions with the oil vapor line running directly into the throttle body. That makes them unique. Add to that the low numbers of cars involved, and the age of the units. It was inevitable that they would skyrocket in price and disappear from the world of parts.

When I got my 360, the price for one of these units new from Ricambia was about $1700. Now, you can't buy them new at any price. Those that are being sold as new are likely just cleaned up and recovered units.

The rebuild option is generally the best as it restores the TB to like new, and preserves the originality of the car. It's been done by people all over the world successfully. If you have a TB issue, I suggest doing that first. For $300, and some easy work, you can refresh your aged TB's back to original functionality.

The upgrade to the 430 units is an interesting idea, but it requires a lot of additional changes, all of which might be a turn off to a prospective buyer in the future. I'm running on my kit and have saved my original units, which were functional when I removed them, for posterity.

 

This is fantastic, thank you!

Maybe I missed it but @EastMemphis is there a write up on swapping the electronics as you mention, that can be linked in this thread to keep it all in once place?

Also, is it a good idea to proactively do this on your 360 BEFORE they inevitably fail?

 

Well done

 

Great info here and thanks for sharing! I can see from photos that you're running an aftermarket air filter cover. Pretty sure the factory cover won't mount to the F430 MAF right?

 

Excellent info, thanks! Love stuff like this.

 

Correct, the F430 / CS air flow meters are wider diameter than stock Modena ones, CS are 84mm Vs Modena with 80mm.

So to make these compatible you need a spacer ring which sits snug around the 80mm diameter of the original Modena air flow meters and is 4mm thick.

 

Thanks Trev. I'm still looking to upgrade mine so we can tweak your tune a little more

 

Trev: Is someone making these spacer rings? By using the slightly larger air flow meters would a 360 owner actually feel a real difference? Thanks

 

I just like that we have 3 viable options now. Whether you want to stay stock, or prepare for future upgrades. I’m also interested in seeing a DIY for swapping the electronic guts.

 

I'm more a writer than a talker, so I made a write up of the process.

It's more than just the rebuild so you'll have to wade through a lot of useless nonsense to find the useful stuff. Maybe someone will make a video.

(I also have a novel or two on Amazon)

 

I have just bought the porsche throttle bodies for a proactive change as to help mitigate the possibility of future ecu failure. After seeing someone used the 430 boots with takeoff I bought some but never realised the 430 TB was larger and I have standard maf so they are too big so sent them back.
I now have another neat solution that I will post pics of when it's complete if anyone is interested, but what it entails is fitting a new hose from the nipple on the top of the oil tank and instead of going to TB there is an M18 blank on each side just under where the TB goes into the plenum so I'm going to fit a hose tail to each side to a tee then to oil tank.

 

One thing that might be relevant is the vent is normally on the MAF side of the butterfly valve in the TB. There's a higher vacuum on the inside of the manifold vs. the MAF side of the TB butterfly valve. I thought about that when I designed my kit and decided that the engineers at Ferrari may have put the vent in that position for a reason. The 430 also has the vent on the MAF side, along with countless other engines.

It may not make a difference, but it just might.

 

I did have that in my mind and am still toying with ideas, if I think there will be to high a vacuum on the breather I will come up with another solution to mount it on upstream of the TB, won't be fitting them untill I service it in a few weeks so just playing with ideas at the moment.

 

On thinking about it after remembering working on my old yank cars pcv systems many years ago my plan won't work as it will effect the idle and will cause to much vacuum in the line and try suck oil through so I'll come up with another solution.
