Hi, I have just the standard turbo on my sts kit, and I want to upgrade to the gt67 ball bearing turbo, or better. I dont know a lot about sizing a/r and housing size. I will only be running 8 psi for this year, and 12psi or better next year. I want to size it so it spools fairly early. I am finding different turbos on ebay but never a gt67 ball bearing. will this turbo work for me ? thanks.

i would suggest you just have someone change the compressor wheel and get the .96 exhaust and that should do you good.

you'll need some serious motor/heads for the 12psi or put it on meth

Many guys, not just LS1 guys have swapped out for bigger turbos, ran the same boost level and run better peak HP and had a much better torque curve. The 60mm is fairly small for our engines, I think you'd do better with a bigger turbo, maybe a little larger exhaust housing and wrap those pipes going back !!

I called sts to see if they had any used gt 67 turbos, I was told that the gt 67 turbo @ 5psi would produce the same power as the standard 60 turbo @ 7 psi. I dont see how but thats what I was told. Also I asked about headers with there turbo system,( most people say headers are no good ) But he said headers will give about 15% more power.He said money would be better invested in other mods, but they dont hurt you they help. I also have 3" exhaust all the way back, he said that helps. Dont know if he is right on all this ?

I ran a 60-1 with a .84 A/R and switched out to a MP t-70 with the same .84 A/R. I think for stock cubes and heads .84 is middle of the road a .70 would be insta-spool and for real top end maybe a .96 A/R. I've seen a lot of people on this site switch to a .84 from the .96.

i bought my kit with the 67 in it and it came with the .96, i was happy because i love doing roll races and i dont necessarily need instant spool because it wouldnt've worked for my style. great power can also be had with a good cam as well...... im experiencing that and im very glad i made the plunge

I bought the STS and upgraded to T67 with a .81 a/r, but I sold it already. It made good power at 8 psi (>500rwhp based on mph in the 1/4). I will be going bigger with more cubes.

Any body knows where can I do a upgrade for my t60?

Sell it to some rice burner and buy the bigger turbo from a reputable dealer.

TRT can swap out the internals to a 67 for like 2 or 300 bucks if i remeber right

Any idea where can I find the compressor maps for the gt60 and the gt67?

just so you know.. NONE of STS's turbo's are ball bearing.. they are bushing

I just called sts and they said they do offer the gt 67 ball bearing turbo. But they want $ 2800 for it. thats crazy. thay said the ball bearing turbos spool faster.

That must be made of precious metals or something. :cough: ripoff! :cough:

that turbo must be made with ''titanium'' for those that don't ever have to worry about the turbo seizing

That turbo went for $1300.. I dont know how much it would have cost to change out the housing to a .96 but considering the price of ball bearing turbo's looks like someone got a deal.. I almost bought it but wasnt sure about it

theres really no need to buy a ball bearing IMO. waste of money, my turbo does just fine. wrapp the pipes back to the turbo and get a good cam and you'll be just fine

From what I have read a BB turbo doesnt make you spool sooner just faster.. But I need a bigger turbo anyway so If I could get a BB for the same price as a non BB I would take it..

If you upgrade the turbo internals, make sure its fully zero balanced on the turbo balancer. If not it will not survive. You can't just swap wheels and machine a cover and not balance the components and then assembly as a whole and expect it to work.
