i believe brian has run one, and IH1206 might be... so there are some running if i'm not mistaken. maybe they'll have something to add.

 

[IH1206]

I have a GTK76 sitting in a box waiting, should have a motor back from the machine shop soon. Ill let everyone know how she is running when the time comes. The turbo is the cats ass to say the lest.

 

[MrPlowJr_EZ_V]

they do look awful purdy! Just not sure if my measley stage 2's will turn it.

 

[thedieselkid]

They will. My "little" stage 2's are going to be spinning a 76 mm turbo.

Then in theory I should be able to spool a 66 without any trouble at all? keeping in mind its a daily driver/weekend drag racer.

 

[DarkShadowDiesel]

i think they have put some regular 66s on some trucks and had great luck - bigr ran a t66 w/ 530 minimes and said it was awesome... i would think a GTK66 would be even better - that's what i'd like to run at some point.

 

[MrPlowJr_EZ_V]

the GTK66 is on BB's site I don't see why it wouldn't work. I think a 76 would be a bit much for my arround the town use and occasional strip runs. its just a work truck that has fun on the weekends.

I wonder how they compare to the TN drop in BB units?

my understanding is that the GTK66 has a wider map than the regular t66 so you get the spool of a 66 with a little bit wider range. that'd be my ideal choice for a single daily driver.
the drop in is a 61mm inducer, so it's smaller than the 66. i don't even know if you could begin to compare it to a GTK, they seem like totally different animals.

I wonder which would be suitable for a daily driver and weekend tow rig with very mild b-codes, but would still be enough to throw a smackdown on the track /ubbthreads/images/graemlins/grin.gif

 

[DarkShadowDiesel]

thats what i am after... brian seemed to think the GTK66

 

[RockinJW]

I know that my replacement .84 won't be big enough /ubbthreads/images/graemlins/phoney.gif

 

[MrPlowJr_EZ_V]

I like the idea of a drop in BB replacement, but my truck needs soo much work its not really practical.

I hate the constant leaky pedistal, leaky uppipes, every fix lasts a few thousand miles and its off with the turbo again.

IMO might as well replace the whole damn thing. I personally have been through enough stock junk to have absolutly no desire to put the same crap back on.

I don't mind spending some dough and getting er done right.

 

[DarkShadowDiesel]

the thing i like about the replacement kits such as H2e and TN BB's is that you can swap turbos more easily - i.e. H2e to QSSB, sled screamer or TN 66 to super 72, and so on.

 

[MrPlowJr_EZ_V]

another deffinate plus!

 

[MrPlowJr_EZ_V]

Looking here CHART

It looks like the exhaust flange is a 3" v-band clamp I have a 4 inch exhaust but IIRC the uppipe chokes down to 3 inches at the turbo.

Can someone confirm this or say I'm wrong? If this is the case, then no downpipe modification is necessary, just uppipes, pedistal and turbo.

I'm no expert but this seems like the cats azz for a DD.

 

[DarkShadowDiesel]

i think for the diesel application it'll be a 4" outlet just like on the t66
