Jeff and Jason, I can't thank you enough for the info you gave me on getting my Z straightened out. After my dealer decided to change out a few of the buckets in the heads due to what they considered to be excessive valve clatter after the Nismo camshafts, the car would try to die after revving the motor. After speaking with you guys and raising the idle to 950 and letting the computer compensate for fuel delivery the car is back to running strong. It is nice to have guys that take the time to try all the mods that you have done and know 1st hand what problems to expect and how to fix them, let alone to take time on the phone to help someone 1,500 miles away. Thanks for your time and info.
BTW, UR pulley came in yesterday and they are installing today, will post dyno after install to see what gains we pick up.

 

Hey man I noticed In your mods you have Test pipes. Have you had any problems with them becides your not going to pass emissions. Like a check engine light or anything else?

 

No check engine light, no problems whatsoever. O2 sensors still hooked up.

 

do high flow cats not pass emissions??? dont know much about emissions and such.....

Ben

 

That would be a question that I could not answer.

 

I just got done installing my UR Pulley and first impression is how HEAVY the stock one was compared to this one.

The difference is amazing.

Jeff/Jason you guys rock.

I'll post more this evening. Sorry if I hijacked.

 

I appreciate the response.

Another ? What is the size piping on it 80mm or 3 inches or more?

Whats the price on them?

Ant Sins4u33 you do pass emissions, but i won't for the reason I'll be running to Turbos with that.

 

I got the Helix test pipes thru GruppeS, I believe they were $199.
