That is a VERY hard to find turbo, I was told that is a custom assemblied unit ( did you get it from Nate at DI?) I would think it would be a great single (depending what AR it has)

61mm inducer is a bit small isn't it?? I've heard to move the air we need on something like that you need a ~63mm inducer??

That's why I stick with "typical" turbos for me...They work well, and I can't figure out what else I could use

You need to call Diesel Innovations and talk to nate he ran one (gt40r )

Signature 600 if you stay with the typical you will never get on top .

and the GT42 with the 1.01 is very nice for a big single it was a big difference compared to the 1.28

I was running one of the NOS diesel kits with a 75 size jet , the hp would be upto the amount of fuel you got.

I didn't say I wasn't learning about what else is out there...just not using them yet

But I have enough turbo's sitting here I think I can find some combo that works good for me. Dodgezilla, HX40-16, S300(62/.7), GT4294, and a B2.

One of these days, I'll get to where you guys are

After seeeing hte 42 in person, I think the 42 would spool nicely... oh wait, that was the original point of the thread.

I don't know about all that...I just can't bring myself to strap on a blue helper. Give it time!!!

I think I'll do the comparing of turbos, thank you I've had enough different one now, I think I'm qualified

All right would it (42) make a good street turbo NO it is just abit to laggy
( not for a 1300cfm turbo though) , but it makes for a wicked pullin turbo ,if I had a stick I would be in heaven and would run the 1.44 AR.

At the pull today it spooled good and ignited my tires( no NOS pullin) to 4500rpm in drive right to the spinout it was a dry track but still had smoke rolling off the rubber.I will give it a couple more hooks and then decide if I love it . GOD it would be a crazy bad stickk turbo.
