well after a year in the making i finally got the coin to go and get my ride tuned....ther list of goodies are as follows:

R34 RB25DET NEOPower FCZ32 MAFsplitfire coilsGreddy PlenumQ45 T/BRC engineering 650cc injectors60-1 turboGreddy 50mm racegatetubular (ebay) manifold (dont say it she works awesome after some tweaking)Exeddy twin disc (pull style)Greddy Profec A boost controllerFAL pusher style fansGriffin RadiatorHKS filterDenso 280 fuel pumpfuel surge tank(not on yet)Aeromotive A1000 fuel pump (not on yet)im sure im might be missing something but this will work for now...lol

ok now onto the power output, at only 16psi she threw down 430whp on 93 octane pump gas. i was only able to tune to 16 psi due to the fact the voltage was dropping going to my pump. which by the way will be fixed here real shortly...lol but the power came very easily and the tuner said that the way the power was climbing with the little things he did that he didnt see any reason why i couldnt get close to 500whp on just pump gas..i plan on going to race fuel once i get my fuel surge tank and my A1000 pump on there..im just waiting till i can afford the fule pump controller which is like 300.00 bones...when i can i will throw up my dyno sheet

That is a boat-load of power for only 16psi! That turbo must flow like a mofo!

You are just running an internally stock NEO right?

Perhaps noobish question. I have not acquired my actual motor yet, but once I do, how can I identify if it is a NEO or otherwise?

it looks just like this one...it is modifed somewhat...i had to moved the back runner (#6) so i coud fit the size downpipe i wanted.also the wastegate pipeplacement on that style manifold is whacked..they mounted it on bottom which doent work at all...major boost creep issues...unless you are running a interally gated turbo which tht wont matter..all youll have to do is to block off the dump pipe and your all good here is what mine looks like now notice where i placed my wastegate pipe and how big my wastegate pipe is...lol

i tried to utilize the orginal locaition on the manifold when i got it...two different size gates, one was a 38mm gate and the other is the gate im running now which is a 50mm greddy racegate...both gates produced creep even the bigger one. the only way i was able to elimnate the creep was to relocate the gate exuast supply. i relocated it into the side of the collector as shown in the picture above. after i did that the creep was gone and the gate sounded alot different..super mean...lol
