What's up guys? I am just wondering if anyone is running the Hahn Turbo upgrade with the Precision 5531. If so, what kind of power are you making at what boost levels and what fuel are you using. I am considering going this route over the ZFR but not sure if it's worth it. Thanks

 

as far as I know they only have the 20g. they never put any others out. but may be wrong

 

Their new kits include precision turbos.

OP i was looking at buying one but they never posted a pic of it and never responded to my emails so i went with ottp.

 

Precision Turbo Upgrade, Cobalt SS/Turbocharged ? Hahn RaceCraft

Here is the link for the new kit. I am highly considering it but I am looking over other options as well

 

They have another site? How big is that turbo compared to the zfr

 

Its a 55mm as stated... 5531

 

So basically the same thing. That's an awesome deal

 

Yah, right now I'm thinking I'm just going to save up for the ZFR 6758...... I might get the K04r though until then. Just to see how that does. I'm not trying to build my motor for a while. Im looking to make around 400whp for now. Probably going to start doing engine work next year.

 

Forget the ZFR.
go with a s256 instead.
