I have a question my buddy sold me his d15b vtec motor... is its better to run a turbo setup on that or a d16z6. What iam asking is which will accept the turbo the best will be only for the track not my daily. If so which turbo would you guys recommend for a d series...

 

i would say t3/t4 57trim thats what I have on mine and it works really good but sometimes compressor surge sucks but I would maybe say gt30r thats going to be my next turbo set with topmount FTW! but good luck to ya.
