I wondered if anyone has, or had, a WRX ph.1 2.0L (with the hydraulic 'soft' cammed cyl heads) and, at first, ran a TD05H 18g... but then decided to swap it for the 20g???

Was the 20g's spool noticably laggier compared to the 18g - or was there ultimately bugger all in it on the road? Did the 20g make the 10-30bhp more that it can do over the 18g, etc., etc.?

Any anecdotal/subjective feedback and/or objective figures/results/graphs, etc. will all be greatfully received...

Thanks.
