Ok. So i just bought a 3076 Turbo Kit made by RNR. I've been told by MULTIPLE people that the RNR kit is weak because the manifold is horrible. So i've decided to replace the manifold. Anyone have any suggestions? I just need something that will fit the 3076. Gotta get it done tho so im open for advice.

 

I haven't heard many bad things about their mani's, only their customer service was poor. To answer your ? I would attempt to use an AMS mani if it would fit.

 

ok first mistake was getting something that was made by RNR. secondly what hotside does it have on it? go to fullrace.com and u may find something u will like.

 

It has a .83 hotside on it. I bought it from a friend. Tryin to help him out. and i know how he drives.

 

im pretty sure i have the same rnr setup that you do, im going to cut off the flanges and make my own. if you have a local shop that you use i would have them do the same.

 

its not RNR's manifold but their turbos. They mismatch the hotsides and thats what causes the low numbers.

But if it has the bigger hotside them you will be just fine. just use that minfold and you will be fine.

I had rnr's 35r kit with the .82 hotside and was putting down 540whp @ 28psi

 

RNR's early stuff was ok. I had they're PTE GT3076R kit and had one of the highest numbers on that turbo, 480whp@30psi.
