i have a 98 gs400 w/ triptonics. i am interested in taking the turbo route. what are my options. obviously the 400 is a v8 but i can't find any kits for this engine. what about transmission. can i use the stock tranny w/ triptonics over 500hp? let me know what i can do even with a v6 and what i am looking at in terms of cost. i am willing to spend 25K. more if needed. thanks.

 

Been there done that.

Let me know if you have questions.

And that transmission definitely will not hold up to 500hp, It wont hold 400 for lone from what I have been seeing and experienced
