Guys, i just got my 240sx and its lacking a bit of power it has a blacktop sr20det with full boltons and tuned with a greddy profec boost controller and apexi safc. I track my cars at harris hill which is a road course and recently took my 240sx its lacking power so i think i want to change my stock turbo setup to a tomei arms kit.
The power im looking to get is around 380-400 whp is it possible with stock internals or should i build the bottom end? Tomei offers two turbo kits the Tomei M7960 and the Tomei M8270 The first one produces around 400whp and the second around 450whp. I will be also upgrading the head with tomei cams, valve springs, rocker arms, retainers , and arp studs.
Basically my questions are:
1-What cam size is best for my power goal?
2-What turbo kit should i go with the m7960 or the m8270
3-Do i need to build my bottom end for my goal of 380-400 whp? Or will the stock sr internals hold that power.
4-Best ecu setup for tuning the car? Hks fcon? aem ems? stay with the safc??
Details on car:
1- Black top s14 sr20det with around 70k miles on it
2- Full bolt ons
3- Put down 280whp on a mustang dyno.
