THATS A BLUEBIRD!

Alright, your motor will come with bare minimum probably too. My avenir didn't come with everything pictured, but came with everything in the text.

Reason why Bluebirds are more expensive on their site ($850 over $690).

Bluebirds were more popular, more desired, thus demand is high and the price is high. Avenir's were the forgotten brother that no one knew had a DET inside. If you look at magazines you probably will never hear an Avenir swap, it's always a Bluebird.

Why? Because Avenirs were in a family minivan like car.

I would go with the Avenir, it's cheaper, newer, you might get lucky and get a W11 (I did at least ). If you have OBDII Avenir is a must!

I think you mean Avenir. The only Bluebird motor I see on the site is $1090.00

Avenir

BlueBird

I know the turbo is clocked down, but that is just a stock photo. As we all know by this thread, Avenirs only have silver valve covers.

That engine also has an AWD tranny, so that picture might be from a GTiR, but once against a stock photo haha.

I've asked them why the prices were higher for the engine, they said it was newer and that's why it was more expensive

Whoops where did that one come from :o I guess I just looked at the title in the sites links.

All of the DET where AWD as far as I know. That is why their oil pans are different, because of the AWD trans

Ahhh haha

And that makes sense, but no way anyone gets the tranny from tiger LOL.

Estimated shipping was $160 for me, but actual was $203, probably all the import fees and other bs.

Ok it is almost 100% confirmed that both W10 and W11's have 2 plug TPS sensors, which would prove me wrong on what I've mentioned earlier. It also seems like that W10 and W11's might have different Distributors as per Adreas Miko.

For those of you who are interested to see what the big fuss about the W11 and Ball Bearing turbos is.

Journal Bearings vs. Ball Bearings
The journal bearing has long been the brawn of the turbocharger, however a ball-bearing cartridge is now an affordable technology advancement that provides significant performance improvements to the turbocharger.

Ball bearing innovation began as a result of work with the Garrett Motorsports group for several racing series where it received the term the ‘cartridge ball bearing’. The cartridge is a single sleeve system that contains a set of angular contact ball bearings on either end, whereas the traditional bearing system contains a set of journal bearings and a thrust bearing


Journal Bearings


Ball Bearings


Turbo Response – When driving a vehicle with the cartridge ball bearing turbocharger, you will find exceptionally crisp and strong throttle response. Garrett Ball Bearing turbochargers spool up 15% faster than traditional journal bearings. This produces an improved response that can be converted to quicker 0-60 mph speed. In fact, some professional drivers of Garrett ball-bearing turbocharged engines report that they feel like they are driving a big, normally aspirated engine.

Tests run on CART turbos have shown that ball-bearings have up to half of the power consumption of traditional bearings. The result is faster time to boost which translates into better drivability and acceleration.

On-engine performance is also better in the steady-state for the Garrett Cartridge Ball Bearing

Reduced Oil Flow – The ball bearing design reduces the required amount of oil required to provide adequate lubrication. This lower oil volume reduces the chance for seal leakage. Also, the ball bearing is more tolerant of marginal lube conditions, and diminishes the possibility of turbocharger failure on engine shut down.

Improved Rotordynamics and Durability – The ball bearing cartridge gives better damping and control over shaft motion, allowing enhanced reliability for both everyday and extreme driving conditions. In addition, the opposed angular contact bearing cartridge eliminates the need for the thrust bearing commonly a weak link in the turbo bearing system.

Competitor Ball Bearing Options – Another option one will find is a hybrid ball bearing. This consists of replacing only the compressor side journal bearing with a single angular contact ball bearing. Since the single bearing can only take thrust in one direction, a thrust bearing is still necessary and drag in the turbine side journal bearing is unchanged. With the Garrett ball bearing cartridge the rotor-group is entirely supported by the ball bearings, maximizing efficiency, performance, and durability.

Ball Bearings in Original Equipment – Pumping up the MAZDASPEED Protegé’s heart rate is a Garrett T25 turbocharger system. With Garrett technology on board, the vehicle gains increased acceleration without sacrificing overall efficiency and it has received many rave reviews from the world’s top automotive press for it’s unprecedented performance.

Ok, I'm just curious. Since these are considered Highport motors, even though it's obdII. What cams are in these motors? Highport or lowport? It almost makes sense if they went with the lowports, but that would also suck lol. Can anyone confirm which set it has? Or maybe even it's own?

Good question! I've been thinking the same! I will pop my valve cover off and measure the cam lobs, and well go from there
