Alright guys, I am taking you advice! I called Cotton’s and Jerry put me on some 60lb injectors with a chip. He said it should work well with my present setup. (I caught myself looking at turbos on their website too!) My wife is gonna kill me! Anyways, I found a Holley regulator # 512-503-5 (35-65psi) this should work with that setup right?

Thanks again, Glen

Hi Glen, welcome. I see my boys have been talkin for me, they're the best!!! Thanks Guys. I would recommend you get the Accufab reg we carry for your car. It's the best out there... with that.. got to run...
thanks so much,

The holley should work.. Unless you found a good price on the holley
The Accufab Is much better + you already got an Order going w/Cottons. Best bet save yourself some shipping cost have em add it in

Ok, Guys….The BIG Question! .... with the mods the car has now ( Magna Flow 2 ¼ exhaust, headers, hot wire, Walbro 255lph fuel pump, 60lbs injectors, regulator and a custom chip) what should I expect down the quarter mile? Any guesses? Oh Yes, I realize I gonna need some wide rubber too. Jerry was telling me there is a nut on the waste gate for adjusting boost. Can you recommend a safe boost level; I have seen it as high as 17psi now. Will I need to back that off or crank it up some?

Do you have a scan tool... Scanmaster ? You really cant turn it up without monitoring it

It sure didn’t take long for ya to find something else I need!!!! I will have to sit down this weekend and read about them.

Thanks

Thanks, great info. I guess i will pull the intercooler next and clean it too.

Hey Guys, one more question if you have time. I have been reading about the factory valve springs on the GN. What some sources are saying is that the valve springs are only 80 lbs new and more like 60-70 worn. They are recommending that they are changed to a mid 90’s LT1 (110lb) spring. Is this something that you would recommend with your recipe? Or is this just a waste of money and time on a low mileage GN. Thank again for your input.

Glen

To be honest Im on the fence with that one.. In one apsect Even though the car is low miles. Its 23 years old and thats a long time to be compressed. Especially If it has sat in one place without being started on a regular basis.
Ok I take it back .. I think its a good Idea to replace em
