Hi, I broke my engine two weeks ago in one track day, I have in my 350z a turbonetics kit at 9PSI witk 435whp, but now I dont have nothing... Only a very big hole in my stock block, So now I´m searching a new short block but now I want one that is good for about 550whp, I go all the months to the track day for to do Drift and Grip and I dont want some engine that is broke another time.
I need your advices and yours experiences with short blocks and if somebody know where I can find a good short block for me, Thanks!!

 

You can either try
1.Forged performance
2 Import parts pro
Both have good engine options.
