man use some spaces and get to the point in your posts, that is so hard to read!! :laughing-smiley-014: it looks like your questions are:
are the engines very strong in the r34 and what are they like to drive?
R34 vs Subaru rx power, acceleration wise?
Well I haven't driven either car before, but I would recommend that you calculate power to weight ratios of both cars to give you an idea of speed, also see if you can find 0-100 times. I've driven an R33 which is similar but not the same and it goes quite well for what it is. Smooth acceleration and quite quick when you rev it out. Hope this helps.
