tach alleman. wants to get me an in audi 90 20v quattro with 2,3l. wanted to convert times to turbo. can you use most things from s2/rs2 or would you rather convert something completely? so the 2,3l motor can withstand everything that no shit motor. so what should you use for that, only around the 400ps. wanted n bits faster than rs2 in the drive. so not hearer top speed. so 400-500ps can he definitely manage. wanted to know if you can make bi turbo or not? because 2 cyl for 1 turbo, and 3cyl for the other??? have the pleuel of s2/rs2 reduced the same stroke or compaction? mfg Jean heide
