Well, it IS possible. But it requires a lot of work other than merely slapping the turbo in there. Usually people are better off selling the car they have and then buying a new car that's already equipped the way they want it.
yes
The turbo off the 300z will fit on the r32, not the manifold, only the turbo.
yes but u will need to switch trannys and intakes
Skyline is definitley more powerful. It is hard to get in the US. The 200sx has a non-turbo 4 cylinder engine (stock) compared to the turboed inline six in the skyline.
over 100,000rpm is the turbo speed.
buy a turbo z. cheaper/easier/less headache.
convert no!!! swap yes!!! You can use the rb26dett (thats the only twin turbo the skyline has) You can not use the tranny from the rb26dett(GTR)because it is AWD the rb25det can also be used(not a twin turbo) You would have to use the sr20det tranny or the tranny from a GTS also a skyline and some different motor mounts and a drive shaft but yes it can be done.
Yes, RB30et
yes and yes, there are many forums and articles on google with this info, along with a good write up on suprastore.com
yes. the r32 skyline gtr comes with an RB26dett motor. the d for DOHC (dual over head cam), the e for EFI (electronic fuel injection), and the tt for twin turbo.
Nope, unless it's a fake electronic one.
