i don't care much for xpsi
you can make 300hp @ 12psi or 200 hp @21psi alot of psi is more heat, and the possibility of lifting the head (since that psi gets multiplied up by compression) ... a ported and oversized valves and cammed 5sfe will make more hp @ lower psi...so if your goal is 20psi that doesn't quite make sense to me ... you can do that on a stock 5sfe with enough octane ...but that doesn't mean you'll make the power you think you'd be making... as far as valve springs...depending on what year 5sfe you're using ...either 3sgte, or 4age, or 2jzge valve springs will drop right in ...some years had smaller valve springs which are compatable with the 4age stuff...and other years had larger springs in which case the 3sgte/2jzge size would fit ...and it's definately an upgrade since all these motors have higher lift cams, and higher redlines... good luck with your project... -------------------- 2005 MB C200 Kompressor- K&N, Apexi WS2 Catback, DIY Voltage stabilizer, Intrax Springs, H&R RR swaybar, VDO Boost Gauge @ 6psi, Greddy L7 plugs, +0 Rear tires
