Hey guys i have a Greddy T-78 kit and i do know the turbo is pretty old ( i got a pretty good deal on the kit though) but I know it's a reliable turbo that can make the power numbers i'm looking for and I do not mind the slow spool for street driving ( will help me keep my foot out of the gas so much.) I do realize there are better turbos out there and I was wondering what other turbos would fit the greddy T-78 manifold that can produce around the same power numbers ( ~440whp at 15psi and 500+whp at 20+ psi)?

well i did a little bit of searching and found out he BW S366 will also fit, Which turbo is more effecient in spool, and making power on pump gas?

 

anybody else have any input?

 

is it a T3 or T4? my greddy manifold is a T3, I am running a borg warner, but much smaller than what you're asking about.

 

it's a T4, it's the manifold that comes with the Greddy T78 turbokit

 

I also am very interested in this information.

 

I also have heard that the S366 fits and that a S372 is close. I have a greddy manifold I plan on running with a 366 and I also purchased an extra manifold to engine flange in case I need more space between the turbo and engine which seems to be where the clearance issues will lie.

 

Yeah, the issue is with the front of the LIM, the vband clamp will touch it. I shaved my vband clamp down, but then decided to weld a spacer on the turbo manifold to space it out more. The problem with this is that now you have to remove the top two studs from the block to get the manifold out.

 

Hardened/black steel bolts are your friend!
