Hi everyone!
im now starting to put together my engine.
s4 n/a shortblock, with a schwizer s3 turbo( pretty big turbo)
i have the pineapple racing large 6 port porting template.
so i think its okay to port the secondary ports but should i port the primary?
the template makes it much much bigger, im a little worried about the low end torque.
should i port the primary intake ports?
also can anyone suggest a clutch kit for 400-500 hp. i dont know how much torque sry.

 

Porting should be fine as long as you stay out of the aux ports.
Are you using TII exhaust sleeves?,TII intake?,Front cover? Oil pump?
If not I'd try to source these before the engine is built.
And I think goopy sells inserts for the aux ports similar to pineapples but they go into the housing instead of the sleeves

 

it makes the aux ports only a very little bit bigger. the shortblock is s4 n/a, everything else is s5 t2. it worked before with the n/a exhaust diffusors but i ground them out now... before it was all stock except the n/a block.
sorry i dont understand your last sentence, what do you mean into the housing instead of the sleeves?

 

You take the aux port sleeves out and slide in a piece that is similar to the pineapple aux port insert, but it fits into the housing where the sleeve was instead of the inside of the sleeve
