I have ported my engine plates today (medium street port) using the pineapple racing templates. Im just thinking that my .81 hotiside will spool really well but get too hot and my 1.30 hotside will spool slowly but will not be efficient higher up. What hotside on a to4r would be ideal on a street port, im guessing the .96??? what do yall use.? i want good spool and 500fwhp

I generally go for a 1.15 with a divided manifolds on the To4R, works well to the low 20 psi range( which is where that turbo should be run ).
