you def need to learn how 2 use the search button its ur friend

 

I made 632rwhp, at 18psi with his kit. Im having boost issues, due to the wastegate springs, being to soft. Im taking it to have it tuned again, with 12lb springs this weekend. Its a very nice kit, well put together. I would recommend it, over greddy anyday!

 

Thanks for the reply bro it helps.But anyhow,can i run an sfr kit on a stock block safely?I know you have a built longblock but i don't wanna go in that direction right now.And since you are from Houston,can SGP racing install and tune this kind of kit?Pls give me some ideas.Thanks!!!!

 

You are already planning to buy this particular kit yet don't have an idea of how well or not it works on the 350Z? Seems like a backwards way of going about things.

 

Tim, the owner, has 2 years on his stock motor an counting. I think, he made over 500rwhp also.

 

Like the Hell out of mine, Tims great to work with,
I did my own install too, thats my 640 @ 14 psi dyno sheet!
DO IT!!!
