If you build like me (when I do eventually go turbo) you could do it in steps like this
1) boost on GE till about 300whp.
2) swap in GTE internals and R154 or V160/161 and then go for 400-500whp.
If my current e-shift trans is built with SRT's parts (trans cooler, sprag upgrade, valve body) what HP would you guys say my trans is good for? Considering adding performance torque converter, just haven't decided if i want to spend the money on one or use that money for a R154 swap. Pretty sure V160 is far too expensive for me..i haven't even looked into the price of a trans swap...$$$$
