Is the k26/8 swap worth it?
Like the title says. I have a chipped 951, and I was thinking about swapping in another turbo from a Turbo S I have access to. Is it worth all the work?

I hope so as I have a rebuilt 26/8 on my workbench waiting to go into my '86. From my understanding we should gain 30 to 40 hp. I have a few other mods including Russell's chips but am still using the stock AFM. I hope to get 275 rwhp.

if it's cheap and you plan on doing the work yourself, I'd go for it - you'll definately have to get a new chip though and probably a 3.0 bar fpr, good boost gauge and controller. A cat bypass (or 3" exhaust) and new wastegate or shims would be nice additions too.

IMO, it is only worth it if you readily have access to K26/8 or got one real cheap. I wouldn't spend any money on a K26/8, as a K27/6/8 can be had inexpensively and is a much more capable turbo...

definately go to the 27 mine was high 12 sec car with it and it would hold 20 psi well to the redline, that was one of my favorite turbos still very quick spooling

Rogue Ant, I'm here in colorado and have the head of my 86 944t, plan on minor port job, manual boost control, and judging price a K27 turbo. Sorry to see the weld on your beautiful stainless exhaust rusting, or is it a coated pipe?

yeah as has been stated- the k26/8 is a great upgrade but if you are going through the trouble and spending money on it i would go to a 27 something. The #8 hotside just moves the power band up higher in the rpm range and would yeild a higher hp #. Your still flowing the same amount through the smaller cold side- now dont quote me cuz im no turbo guru this is just my simple version- the 27/6 would flow more and spool faster but run out of breath up higher in the rpm range where my 27/8 spools slower but has more air up higher in the rpm's- meaning higher hp #'s theoretically but not necessarily the fastest spooling turbo around- still pretty good. New powerhaus k27/8's are around $1200 new but you could find a deal on one somewhere im sure. Keep in mind that you'll still need everything to go along w/ more air flow, bigger turbo inlet and tuning wise....

For an afternoon's worth of work it is a great upgrade if you can get it at a decent price.
While the 27 is a decent upgrade, the 26/8 won't require a MAF, bigger injectors, modified water pipe, larger silicone boots, ect. It's hard to beat a 40 WHP increase for four or five hours worth of labor and less then $600.
