I'm sure this other option is harder to install but the prices are close...
http://www.lindseyracing.com/mm5/mer...944TURBOSSUPER
LR-SUPER61
Price: $1,175.00
vs.
http://speedforceracing.com/products...bochargers.php
SFR GT30R turbo upgrade - $1299.99
"These are real GT turbos and we modified them so they will bolt onto the stock engine mount.We modified these turbos to use a TO4E compressor housing.These turbos utilize a T3 hotside so they will NOT bolt up to the stock crossover pipe......"
OTOH. If the K27/6 even comes close to the same power and efficiency the price difference is soooo huge!!

sure is!
I was showing that there are aftermarket turbos that spool as fast as the K27/6, and it was easy to do since there was a link to nize's thread right in this thread.

John,
Sticking to compare a K27/6 and a LR Super 61, both would probably meet you're goals. But for the long run, if i was in you're shoes, i would go for the LR super 61.
The LR S61 would have a lot more potential, you would probably not need to replace it when you look for more power (being said that you're power cravings are not too wild). The LR S61 would also create less back pressure (in theory) due to a larger exhaust housing, compared to the K27/6.
If you searched for the LR S61/65, the users recorded a ball park figure of 1 bar by 3,100-3,400rpms, which is acceptable.
The K27/6 is old school, but parts are known and reliable (KKK's are reliable as heck), Garretts are more efficient. Plus it is easier to upgrade the K26/6 to a K27/6.
That's , my opinion only. A LR S61 has more potential don the road than a K27/6 (it will run out of steam eventually compared to the LR S61).

I just purchased a scivision maf from Russel (should arrive in a few weeks). He told me if I ever upgrade to a LR super 61, I would NOT need to get new chips. I'm assuming (
) the same would apply to a K27/6 upgrade.
With your basic bolt-ons and a LR super 61, I think mid 300's would be achievable while keeping the quick spool up. Thats the power I want out of my street car down the road.

Im curious, for a K27/6, what is that level of boost where you are basically past its efficiency range? It seems for the K26/6, anything much over 16psi and you dont see much change in anything other than torque and high EGT's due to back pressure. What are typical numbers for a K27/6 around 15psi and say at 17psi (with the usual bolt ons).

John,
Overall driveability had definitely improved since the install. I haven't had a chance to dyno it yet, but it feels stronger. The car is docile at low speeds/moderate acceleration, and when I open it up the dash mat likes to fly at my face. Did you have a MAF on your old setup?

I'm keeping that and adding a lindsey stage 2 ported head. I think the k27 will be a nice fit.
any bolt up difference between a 27/8 or 6? what should I be looking for?

I was looking at a super 61 I think(after doing alot of reading) or a 27/6 I found on evil bay...
opinions on the super 61 turbo??? can anyone chime in. I would prolly run 17-18psi on pump and I would up a couple of pounds with good fuel every once in awhile. Can that turbo support that??
I hear the super 61 can hold 20psi all the way to redline. Thats all I would ever need.
how much power did you make and at what boost level XS
btw vitesse doesn't list the price of their turbos on their website. What would a turbo from them run(built for a 2.5ltr)

>>>Yeah I agree but, honestly im building a track car using a ls2 and thats another animal unto itself<<<
Which makes the decision you're facing a mute point.
Wait until you drive the LS2.

this is a street car. I dont need crazy power if I could squeeze 400hp from a glory run and put around at 375hp thats all I would ever really need.
a 375rwhp 951 is a quick enough street car to atleast have fun in. No one here expects the 951 to be a hwy beast or anything.

Unless ofcourse you are saying that the point was incapable of speaking, which is in and of itself, comically absurd.
Look up the word "moot" and get back to us.
