Not really a whole lot to update, but i did get some small stuff done!

Alt. is relocated and every sensor/wire is plugged in/rerouted so far!

Also pulled off the hotside and painted it with VHT flameproof paint to cover up the welds and make it look a little better, although i'll most likely wrap it all eventually!







I'll be picking up my fuel rails,feed/return lines and shifter on friday along with ordering my fans/coldside stuff this weekend, wont be to much longer before ill be able to fire her up!

Thanks!

I was going to do twins myself, but the thought of buying everything twice kind of knocked that plan out of the window!

Yep the cost does suck but I think it will be worth it. Building a 67 rs camaro that has gotten kind of over the top. Funny how it has snowballed to this monster but gonna be amazing. Enjoying your build. Having two ecu's setup sounds like a great idea I may do the same!!

What is the limit for most on pump gas? I am going to look at a roller today (the text i sent ya of the 97) and would love to make mid/upper 500s with an LS6 cam setup, FAST 92 and stock heads and bottom end....soo....where do most max out on pump/93? this will be a weekend car so id love to corn feed it but we dont have anywhere over here for E85.

I was more meaning of getting both tunes on seperate ECU's, that would be a little expensive!

The 5.3 S480 240sx is around 600whp on pumpgas and 6lbs of boost (trapped 135mph), tuner claimed upwards of 12lbs of boost would be the limit on 93.....

And thanks Jay!

Not really alot done latley, but every little bit helps! Still waiting on my fans to get here and a buddy of mine is going to get the intercooler piping done hopefully by next weekend....

I did however pick up a set of fuel rails (hate the color, but for $50 i cant complain!)
Also made a crossover for the rails as well as getting the rad hoses on, hopefully work will pick back up so i can order more parts and get this thing done!
