I know the the Z3 kit comes with the PT6262 turbo, but can the kit be ordered
with the smaller PT5858 turbo instead? Not that there's a big difference between the
two, but i'm interested in making a ton of TQ as early as possible an figured the smaller
turbo would do that. just curious.

Thx.

 

I'd suggest emailing zzp directly to ask. There aren't a ton of turbo cars on here, and I've never personally heard of anyone on any forum buying the Z3 kit with a different turbo. Not saying it's not possible, just that it isnt common.

I do have to ask though, if you're shooting for 350 whp and want the most torque as soon as possible, why get rid of the M90? No doubt, itll cost more to get to that power level, and will be nearly maxed out, but you get a ton of instant torque.
