The N/A 3800 is definitely not an upgrade to the 3.4, IMO, but they are easier to find and find parts for. The supercharger whine of the L67/L32 is great, but the 3.4 sounds so good revving out, especially the induction noise. 3800's sound like a vacuum cleaner. I am a fan of the LQ1 and the L67, etc. and it was cool to me back in the day to L67 swap the older GP's, but as time has gone on, now if I got another 1st Gen W, i would keep the 3.4.
