gtk 850?

[chops]

Opinion needed I found a gtk 850 72mm turbo for a good deal with 200miles on it am going to be putting on ta alm fully ported on over the winter stock bore roller cam will I need an 3800 stall to spool that turbo ????

You will need a lot of engine and a really good converter to spool and couple the potential of that turbo. A fully ported set of TA's will flow more air than any hyd cammed stock block engine will ever come close to using also.

Brian should I just stick with getting a 6765 journal bearing with a billet wheel ?

The 6765 turbo could power your car into
the high 9s. Do you plan to go faster than that?
If not, keep the smaller turbo for drivability.

All I want john is a 10.50 street car I was told my 61 is good for high 10s I don't know ? Am a mustang guy new to the buicks I guess my best bet is to get ta porteds and test and tune from there

The heads and the 6265 or the 6765 will get you there. No need for the 72

 

[chops]

I guess your right since I do want a daily driver

 

[John Wilde]

IMO the 6765 will get you there easy with room to grow.
The 6265 should be able to go low 10s and you can keep your 3200 converter.
