@Insane
I Can Smell Insane Going So Against TOYOTA 
Don't Know Why.....!Maybe Some Bad Exp's...! No Worries
Well 4AGE Know For Its Best Till Now All Over World.....Ppl Still Swapping And Doing And Doing......! And Getting Nice Results....!
One Best Engine Designed By Enginners Of YAMAHA And 4AGE 20v Which You Call Joke Or Whatever Is A Team Work Of YAMAHA Have Been Pioneer and Supporter Of The 5-valve design.Yamaha Formula 1 Engines Had 5 Valves Per Cylinder It Self.Also Remember YAMAHA R1 Engine's...! In Terms Of Max Valve To Surface Area- The 5 Valve Design Cannot Be Beated Theoretically and Geometrically.In Japan These Engines Were Used In Formula Toyota...! So Much This Engine Used In Racing As A Pure High Revving Low End Torque And High Revving Horsepower Figure Engine And You Still Say....Its Joke?? 
B/w...3S-GTE Won't Replace 4AGE.....4AGE Is Replaced By Z-Gen Series.....!As Corolla Never Exist With Any S Series... Its Celica , MR2 Platform......! 
And With 4AGE...Levin/Trueno's Also Ended That Still Rules Racing Track When It Comes On Handling/Balance Power On Circuit Tracks Against Rival HONDA/NISSAN....!
@levin.....Think Many Times Before Doing This As 3s-Gte Parts Are Very Rear Find...And If Someone Mess With Controller Like He Did Earlier...You Can't Even Get That....
3s-Gte..awsome Motor...(y)But With Some Much Exp And Rear Parts All Over...Still Not Flooded In Market Like 4AGE Did....!
