So whats next?

I currently have a 07' TR with a turboback and Cobb stage 2. I want my car to scream and dont know what to do next. I was thinking FMI and a 20G turbo with appropriate injectors and fuel pump. Then a protune or Delta EM or whatever. Im not real worried about suspension or spool up time.

My other concern is the transmission gears as i have already had to pay to have them replaced. Should i go with some dog cuts? They are damn expensive. STI tranny? Also expensive. Is there a cheaper effective route?

Thanks and sorry for so many questions.

Well i want to do that but the STI tranny is way out of my budget. I found some gears that Vivid Racing sells for $1699. I can do that. What do you think?

Look into unequal length headers if you want to keep some of that boxer sound.

Ok sounds good. So what about a FMIC? Should i spend less and get a TMIC?
Will heatsoak really play a factor?
