i dont really kno much bout turbos but i will by the time i get one. i kno u can set ur vtec engagement at a certain rpm and u can buy turbos that spool up at a certain rpm. my question is would it be good to have ur vtec and turbo spool at/or around the same times? or would it be better to have vtec before/after turbo spool?

 

Vtec has nothing to do with Turbo spool characteristics. Buy whatever turbo you want. and set the vtec engagement where the low cam and high cam torque plots cross paths.
