Turbo'ing an S15 Spec S?

[StuyMac]

Whats needed to make the Spec S turbo charged?

What are the engine differences between the R and the S, and how much different is the R from an S14 engine?

Cheers

The SR20 engine is exactly the same as the SR20DET, apart from a higher compression ratio and ecu. (So they say on the aussie sites!)
If you go onto the hks website(HKSUSA.COM) and do a search for sr20 it should return a list of parts. There is a very nice turbo kit for the SR20DET on there when you do this search which uses there siqniture Z turbo
