This is very true,and you wouldnt have to redo the exhaust flange.Ooooooor could have yellow chevy port and polish the 366Why not buy another decent used stocker (or rebuild yours) and just have yellowchevy polish it up?
You'll keep the same driving characteristics and also gain a little power/boost.
If you're interested James I could ported/polish a stock one for you and install a batmowheel or keep the stock wheel.
If your wheel hasn't hit the housing I could rebuild it with new parts; both options would be much cheaper than $2500.
Just throwing that out there as another options for you.

James the 366 would be a direct drop in other then redoing the exhaust flange you would not have to have different ic pipes.
Ditch the twins....run a 472 with a diverter valve...
James quit being a ***** and run the 475 as the valley charger then get a real man's turbo so that it has company.
Not sure but i heard that DTS has HTT build them.
The DTS still has a stock turbine wheel, so you may not benefit from any better turbine flow, but you've been running a stocker for however long as it is, so it may not matter.
The Fleece Cheetah comes with a 63mm billet compressor thats proven to support more horsepower than anything we've tested in its size, plus it comes with a larger 68mm Borg Turbine for better flow over the stock turbine, as well as a Borg Cart for better reliabilty, and a remote oil feed setup to save the #4 Cam journal bearing. There is also extensive machine work done in the turbine housing to optimize flow, for better response, EGT management, and to reduce drive pressure. Its not cheap, but it is the most labor intensive charger as far as assembly in the FPE lineup, and for a drop in replacement, you are getting your moneys worth.

A compound setup is only as good as the high pressure charger can flow, in your specific case, if you have something that spools and drives the same, however it's capable of flowing and moving more air at the same or slower speeds, your going to benefit from it. It will maximize your compound turbo setups potential, and expand on the gains you already experience from the 2nd charger.
If you dont care to further lower EGT's, increase driveablity, and gain some more horsepower and torque, then you may not want a Cheetah! :roflmao:

James get a dts or fleece, they both run great and spool great! Or get a t4 billet 66 i have zero issues towing and lag
I have been wanting to do this exact thing to my stock turbo. I want the same things too, I had a 68mm cheetah that "spools as good or better" then stock. I can tell you that it didn't. I know it was variable but I couldn't hardly use cruise control at 60mph with my 3,500# boat on it without blacking it out when i would start up a hill. I think if you go with any bigger turbine, you are going to lose some spool at low rpm. I want an upgrade but 100% will not be a cheetah. I have talked to Danville and DTS and still really not sure what to do. Lot of money to maybe not like it
