Doh!

 

check out the FAQ's..... search search search.
there is no 13btt. there is a 13bt, of which there is an s4 version and an s5 version. theres also a 13b-rew, which is the 3rd gen engine, a 13b-re, the cosmo motor, and the 20b three rotor monster. search search search.

 

If you want ~ 300 whp do the s5 13bt with a streetport, extra dowels, standalone and turbo of you choice. If you want more 450+ go with the 13bre.
