Wow so the divided exhaust really does make that much of a difference! I was just wondering if the difference in spool between this set up and jeffs wasnt because this was a BB turbo. So actually you might be able to pick up a little more spool with a BB turbo, not that the spool isnt already awesome

On a side note...A lot of this has to do with tuning, and how much risk the customer is willing to put in to it on a stock block. This is why comparing even same dyno (brand) charts is so pointless. The tune makes things happen.

Lol...you make it sound like you have the old Garrett diesel turbo.

In truth, looking at the overlays of back to back pulls between the 65 wheel and the 66 wheel on Reid's supra the new 66 wheel puts the old one to shame in both faster spool and more power.

There will be a 6266 T4 .81 a/r on the dyno with the mid mount kit soon enough, so we shall see how it does.

The 66mm wheel is better for sure, you can see it as soon as you look at it. The fins are much thinner, so lighter, and I am sure that has a lot to do with spool and flow.

Awsome work but i do have a couple of questions, comments concerns. Ground clearance, having the turbo there would make me think it will easily be damaged. Next would be transmission heat, that trans already runs hot as hell as is,then the turbo and pipes right there, cant see that good for the bearings nor could i see this beeing tracked without an external trans cooler.

You can get a small T3 turbo, which does not produce any heat, and stick in the cold engine bay, where it will create just enough heat to keep everything happy.
I guess this kit is not for you my friend.

I'd say turbos are more likely to fail near the engine core vs the transmission! And they don't fail there, so... non-issue. And if you're going over questionable terrain in your z/g and worried about the ground clearance, I'm sure you could get someone to fabricate a skid plate. I suppose ripping out an oil line by running over debris on the highway could be a concern. I've seen a friend's car with a cracked oil pan (on his old volvo) from running over a truck tire fragment at highway speeds. I'd just call that unlucky though...

if going down the country washed out dirt roads at my parents indiana farm doesn't hurt it then it won't get hurt driving on the road.
This sits above everything that hangs down so unless you do rock crawling and plan on taking out the crossmember then the turbo will not be touched.

Please go read all of Sasha's build threads. This issue has been addressed already. I don't understand people sometimes.....
Like Sasha would put out a quality product that get's hit with rocks every time it's driven.

A little of topic, do you guys think that the mid mounted kit with a quick spool valve and the 6766 would give similar spool as the twin scroll ?
I'm highly considering the quick spool with my 6766 but just don't know if its worth the money

it actually does quite a bit for it. in fact i had a dyno i had sent sasha before that showed a rb26 running a JB vs BB 6765 other than that nothing on the engine was changed but it picked up 35 average whp vs the JB from the quicker spool. NOW with that said it does absolutly nothing for boost threshold which is the point the turbo first makes boost and some people confuse it with spool, or how fast the turbo makes boost. it also wont do a thing for peak power but it def helps with power under the curve which is def a good thing. up to the user if its worth the extra cost for a little bit extra power in non peak situations.
personally i think its worth it to pick it up for anything but drag racing, since drag racing it wont do much after first gear.
edit dyno to back it up exact same engine, same day, same boost, same dyno, same fuel only difference is JB vs BB turbo blue bb red jb
konrad i think thats a huge can of worms which has been debated on many forums and you probably wont find an answer. some say all the gas going into one volute will spool faster with the qsv(with a possible lower boost threshold.) some will argue that the perfect pulses from having the tubes divided will give quicker spool than qsv but not necessarily lower boost threashold then open volute. ive personally been looking at it alot and havnt really found anything conclusive. owner preferance and he says she says is about it. either way qsv will give you better spool and mayby a lower boost threashold(some claim they have seen initial boost sooner but havnt found anyone post dynos of initial boost, its always starting after a couple psi are already generated.) just remember you will have to go pretty big to match the flow of a open. precision told me the 1.32 divided housing was about the same flow as the .96 open.
