It's Refresh's curve that I love the most. Solid power all the way to redline. When the 26/6 gives out - the 50-trim just keeps on going!
For the few DE's I do each year, having that extra fatness in the power band would be SWEET! Made the mistake of taking a ride around a local track in a buddy's 944 Turbo Cup - where I'm short shifting to 4th at 5500 cuz I'm out of steam, he runs his all the way up to 7,000 - and it makes power there. Love that... want that.

For a 3.0l I think a GT3582R with 0.82 a/r is pretty much a perfect match.
I've driven several different 3.0l engines with both 8v and 16v heads, different cams etc with this turbo and to me it's the perfect compromise between spool up and power.
It is on the small side for my 16v turbo if I want to go over 1.1 bar but I will change to a Tial 1.06 a/r housing to gain a bit up top.
For ultra spool I have a GT2876R which would be fun to try out on that engine as well
A divided housing with quick spool valve is IMHO a bit of a waste. It's not a win-win setup and the effort and money to get it to work would be better spent on other things.
Either a true divided crossover with 2 wastegates or a well matched GT (or similar) turbo is IMHO the way to go.

Seeking advice/thoughts from 951 folks who've upgraded their stock K-26-6's:
I've been offered a great deal on a stock Borg Warner turbo S turbocharger for my 87 951 which has a Lindsey Racing boost enhancer, circa 1997 Autothority stage I chip, 2.5 inch test pipe and 3 inch exhaust.
Will installing this Borg Warner turbo S part on my 87 951 result in any distasteful characteristics like more turbo lag, etc.? Gut tells me I'll need to upgrade to a modern custom mapped chip set but I'm hoping I won't even have to do that. The engine was overhauled by Broadfoot recently and runs extremely smooth and strong and I'm concerned such a part addition would screw up the Karma.. EG, new kitchen wallpaper spells wife now requesting new counter tops to match.. arg. Current stock 87 K26-6 turbo was overhauled but smokes occasionally and I think I might need to get rid of it. Not looking for more power necessarily, just a fun factor daily driver. Thanks in advance for any thoughts.

If you decide to get a 26/8 i have a vitesse chip for that for the early turbo dme. I believe they are 24 or 26 pin vs the later dme. Youd need an mbc or ebc with a 3bar fpr to run it. That setup with a dual port wg and test pipe woul put your car around 270-280rwhp
