Majestic turbo in Texas can make you a hybrid out of your K26. They install a lager turbine in the stock 6 hot side and a little larger and newer designed cold side. With a 3.0 fuel pressure regulator and some simple autoauthority chips this turbo gives quick spool and enough cfm's to hold 15psi till redline. Good for around 285 HP. You would have to get into some more mods to break the 300 HP mark!

Also, if you change your turbo, you will need a lot to go with it to manage fuel, timing, ignition, boost, etc. Your car will be pretty far from stock when you have it properly set up. If you don't do it properly, you won't be driving your car long.

You many want to start by looking at the K27/6 as it may close to what you want. It generates more boost at similar rpm and will hold to redline. And, yes, it's just as old of a design as the K26/6 or /8.
FYI, it is safe to say that he knows a thing or two about the software part.................maybe you do a search and find out what chips/MAF etc he developed..............in use by members of this board.

The K26 from the 968TS would be my dream turbo. >14 psi@2900/min. But I can't find a source for that part. So I'm looking here for an alternative...
Yes its not a problem.....I am running the LR Super 61 witht the Scivision MAF using the LR adaptor and cutting off a small section of the J-boot.

I know it's not a problem but LR doesn't sell the J-boot adapter except if one's buy a new turbocharger from them... I consider installing a N/A J-boot (à la ST) to keep a OEM look (instead of the Powerhaus adapter I have as a spare).

I can't find any pic of the 968 TS adapter...

That looks interesting - thanks for the link.

@marcoturbo: The 968TS adapter is similar to the LR version. It should not be to difficult to rebuild it.

In general, the turbo should fit into the stock 951 configuration with a moderate power goal of 350 flywheel hp. Stock means with original DME/KLR control and all original hoses etc. and a good drivability for everyday use.

Thanks for all the input...

Maybe they changed their policy. I bought the adaptor from LR 2 years before I got the LR turbo. I was using it for my K27/6

Tom,
You should try Charlie at Evergreen turbo 1800 275 2531. He is a turbo builder who has a lot of experience with 951's. He made me a custom turbo that is fantastic. It is based on the KKK and has been trouble free.

Sorry to sound so pessamistic, and somewhat frustrated, but i'm getting confused about all the mixed messages relating to turbo performance. I've heard alot about the so called huge leaps forward in turbo technology over the last 20yrs from many forums. If this is the case then how come it still seems like the holy grail to get a turbo that can spool up as quickly as a 20yr old k26/6 and hold decent levels of boost all the way to the red line? Seems to me that we are still struggling to achieve the boost retention characteristics of a larger turbo whilst getting k26/6-like spool up performance. If the answer to the question "Can I get a turbo that spools up quicker than a K26/6 but holds 15psi to the red line"? is 'no', then things don't seem to have moved on that much.

He's the guy that builds the turbos for PowerHaus.

I think your right in that he builds turbos for Powerhaus. He builds turbos for many tuners but also builds custom applications which is what I needed. I wanted to stick with the KKK but not the stock type turbos that PH sells so I used Evergreen.
It sounds like Tom wants to stick with a turbo that is factory based so this is a good option for him.

Just curious... Is there a 26/8 replacement that uses newer technology like ball bearings that would allow you to use your current a-f mapping/tuning?

I am not saying anythign bad about ball bearing turbos - they are fine for certain applications. Just wondering about the statements....
