Would make a nice torquey little motor, and you'd be able to use a stock clutch. On the other hand, I'm not sure the k27 is an easier fit than most hybrid turbos really, and a deeper breathing turbo gives you the option for more power when you (quickly) start to want yet more...

I dont know, If good deals come along money's available within reason, I dont want to look in the engine bay and think there's a Ducati 1198S in there somewhere though . As for tuning Rogue or Vittese probably though a guy in the UK is making some progress but it's early days for him.

try looking for a 7200 k26/8, they pop up here and there, look around on the 930 board as they use them also.
Look into an intercooler also. the stock one is good but i rather get something that can cool more air quicker. besides the stock one is restrictive unless modified.
Just remember:
pistons: $1000
Rods: $1000
gasket kits ~$500
Clutch: ~$1000
chips&maf $1400
.....5K in it already..

1.2 bar is 18psi. Without a lot of details at 18psi a 3.0 litre is very very quick. If you want a over 400HP street engine on pump gas then it gets a bit more complex. If you are going to run E85 then even a K27/8 will let you run 20psi for street use, just don't run it on the track for 30 minute sessions without a whole lot more intercooling.
I just know that at 1bar my 3.0 was very quick and at 1.2 bar it clocked a 121mph quarter mile. If your goals are higher then I would go to a newer Ball Bearing turbo right off the bat.

A bigger turbo will flow MUCH more at a lower psi\bar as in cfm (amount of air) Turbo pressure as in PSI\BAR is highly overrated.
Look at a k 26\8 for example, it may hit 1bar but a bigger turbo at 1 bar will produce more TQ\HK and not drop off in the top. But ofcourse the low end disappears with the bigger better flowing turbo ..
I kind of miss the k26 at times when it comes to lag. Next build will be with a relatively small but modern turbo were spool and lowend will be key not whp

Around $900 so not really worth the compromise, I wondered if I could build something useable out of the LR75 and my K26/8. Though didn't your friends LR75 show signs of wear quite early ?.

k27/8 on my original 3.0 8 valve head car. Was purchased from David Raines of powerhaus at the time. Was one of the fastest 968 cabs around at the time, a lot of low end tq, but ran out of steam at the upper rpms. Went with a to4 60b / 10 hot side currently.

I've read pages and pages here but still dont know if a K27/8 is big enough for a road going 8v 3.0 or how much boost it will run safely. I'd like a fairly easy bolt on and I'd rather not spend $1k + on a turbo but I guess it's pointless to build a 3.0 and then choke it with too small a turbo, does a K27/8 work ?.
