my tc76 has never been run, If i were to send it in I think I would rather trade it in.

my tc76 for a new
tc78 with a race cover and f176

what would the extra cost be?

We don't have final cost on it yet. But are you looking for the GTM version?? Also the new HP billet wheels will be available as well

yes the GTM cover.

so basically ill have a turbo that will be nasty on stock ls1 that will be perfect on a motor up to 400cid and maybe 900ish hp with just a hotside housing change, correct? im not real familiar with the power potential for the HP billet wheels with a gtm cover.

AND, when people pop the hood it will be HIGHLY deceiving

Yes the GTM cover is nice indeed. We will dyno one soon with a billet wheel and 347 with the new turbine wheel as soon as its all ready.

How big of a wheel we looking at? Stock is 68.5 or something right? Can we get a sneak peek of the AR's your gonna offer?

Man i think im pretty maxed out trying to hit 700whp on my car with a 370ci. If you guys did do this and went with a big exhaust wheel size man that would just be amazing. If it was a 78 or maybe over 80mm exhaust wheel i would be loving life! and a 1.35ar housing!

Ill be one of the firsts on the list then. im scribing to this tread now and ill be watching out.

But I think ive heard many rumors about tc 76-78 upgrades but its never happened from the past. So don't let me down!

Well the current largest wheel offered is the 82/75 GTS turbine.....this turbine will be the specs of 83/76. To get 80mm exducer, then you need to switch to a GT45 style charger or one of our 87/80 LDP Borg Warner turbine wheels.

Working on them as we speak. Hopefully in just a few more weeks. We will CNC the GTM covers here and only takes a few days.

Yes...and a lot less bucks. Mid-frames are built on a "GT42ish" style platform and BB only. These units are still the smaller style TO4 frames and offered in non-BB platform.

I'm running twin TC67 turbos. What turbos are close to the same size but will give me the ability to make more power. I've made 800 on 15#, but would like to make 1000 on 20#. I'm running a 408 LSX block with TFS 245 heads.

TC76's would easily hit those #'s and drop in place of your current chargers. Let us know, we can beat anyone's price on them.

Housings are the same as the mid-frame except for the turbine housing. Different casting. Turbo will come in sooner due to a lighter shaft design, but maybe 1% or so down on turbine flow due to the casting difference.

I'm in the market for a unit and am looking at the 7876 for my 383. What turbine A/R do you recommend and do you offer a V band inlet/outlet?

They are T4 only on the inlet, but V-band is the outlet. As for that size motor with this size turbine wheel I would jump straight to the 1.15A/R housing. Spool good and won't choke up top. With that turbine wheel it should pull clean to 7K+.

For those that PM'ed us.....yes we will match a GP price. As long as that GP is valid.
