OTTP Stage 1 kit
 

I'm looking at buying an OTTP stage 1 kit, along with a few different cooling mods and meth injection. I just had a few quick questions

Which brand H/E would be cheapest, and has the easiest mounts
Which brand of Meth injection, and how large should the tank be
60# injectors fine to run?
Rotated tranny mounts?

Thank you,
Ian
