Well from my personal experience UAM and sts did an
Amazing job on the 2010 nismo STS 370z it was built and tuned in the USA
And they overcame alot of simple issues but in the end the job was done then shipped half way around the world to us although we have different temps, sea levels etc etc but the the car runs perfect and tune didn't need anything althouh it was tuned on 7psi and we increased it to 11.2 psi approx and still is amazing tuning , I will post dyno vids and graphs soon but it made 450whp on dynapack in the USA on 7 psi and some change and passed 500whp on dynojet once boost was turned to eleven and some change ,believe it or not full boost is at 3800 rpm to 4000rpm but once on the dyno the graph showed us the best torque curve is at 4500 rpm so if we will roll race not on the streets ofcourse it will be at that RPM , it's a very good kit for the price and changes the car to an amazing beast and it smoked a GTR and a 911 turbo both are stOck I guess and they were new models , their is alot of advatanges such as sound ,performance etc etc , but the dislikes are as follows
The sound of the pump is a bit on the high side at the back, gets abit stinky as well lool smells like hot oil , didnt smell that with gtm kit,and the pipes all the way at the back are on the low side so the driver needs to be careful on bumps and stuff don't need any leaks or why ever , we are trying to overcome the p0106 code that pops up all the time but as long as it doesn't effect performance it's all good , we did notice that intake temps jumps fast from 88c to 97c on pulls once boost increased in 20c weather and it wasn't hot so I guess regardless turbos are in the front or back these new 370z's really hate boosting unless u add things like methanol and cooling upgrades and other stuff and that is something we will do very soon and increase boost to 15 psi and see where we are but next season I guess it's getting hot here now so season is over almost , anyway this is my honest review , the one million dollar qustion is will I go for sts kit or gtm , I can't answer that yet , it depends on taste as well for example the owner of the sts didn't like gtm kit and the gtm kit owner didn't like the sts kit ,we are gana make a roll race between both cars STS nismo vs 40th anniversary GTM stage one , in the end it depends on the budget and personal prefrence but if it was me and wanting to build a 370z I'll go with gtm for sure or any twinturbo kit because I prefer twin turbos all the time
UAM all the way , let's wait and see how the greddy kit will do compared to those ,I'll keep u guys posted
thank you all
