So anyhow because of a friend's questioning I got to thinking..... What new technology could be used to make a fun Z31 daily driver...

The turbos that came to mind were.........

GT25R (various housings)
Silvia S15 turbo
Pulsar turbo
Cheapturbo immitation but not quite GT28
and the Disco Potato...


This is because the target car would be an 88-89 Z31 with a T25 flange..... I know that the earlier models with lower compression would make more Hp in the end but I'm more concerned with responce and torque here... daily driving car...

We need not talk about the other things needed for this sorta project just the turbine...



There was talk that the disco potato while sucking at the SR would be more suited for the KA-T because of larger displacement, however.. I'm thinking that its "envelope of efficency" could also include a SOHC 3 liter V6....

The S15 would prob be too small for the same reasons that the potato fits the bill... ( i could be wrong on this)

The GT25R's would be interesting also with the .86 (.82 whatever I dunno)
The pulsar turbo I dont know enough about to make a judgement on...


OK so post away.. This has me very curious as to how to make a 300-330 WHP torque monster Z31 for daily driving..

It wouldnt own all but it'd be fun..
