Its a MPGT45 thats pretty much all I know. There was only one size offered in that. But what would this be equivalent to in "T" like a T-70, T-76,
Im just wondering because everyone asks me what size it is and has no idea what im talking about when I say GT45. they want to know what T-??
And what is actually "45" on this?
I want to say the turbine wheel was 81mm ? sound right? so would it be a T-81?

 

I am also going to run a GT45. Here is what Ive learned:
A/R ratio is 1.05
It is similar to a T70 on the inducer side with almost 70mm. The exhaust side is almost as big as a 88mm.
It seems that it is a good size unit for a street car with drag radials, as it is still small enough to not overpower the tires but the exhaust size will give it good top end flow and not choke as early as a standard T70 unit.
Do you have any times on your car yet? Mine is really similiar with a 6.0.

 

No times yet, easy 10s im guessing... no clue really. I cant take it to the track till I get disc brakes in front. Im still on manual drums...lol. Street car with drag radials? w/ a 4-link and 12" wide quick time pros mine is useless in 1st gear and most the way into second.

 

Dial in that suspension, get it to hook, then post some wheels up videos for us to watch!

 

GT45 has 68mm inducer wheel... so its a 68mm turbo with a big exhaust side.
