[Dragondog]

OK WELL I DID A LITTLE RESEARCH LEARNED A LITTLE BOUT BEAMS RED TOP AND BLACK TOP FROM WHAT I READ BLACK PUT OUT MORE THEN RED BUT RED HAS MORE PERFORMANCE UPGRADES AVALABLE IS THAT TRUE?......WHAT I DONT GET IS SOME SAY BLACK TOP IS NOT DUAL VVTI AND RED IS BUT OTHERS SAY BLACK TOP IS MAYBE IT DEPENDS ON THE GEN..THE BLACK TOP I WAS LOOKING AT COMES FROM A ALTEZZA.........WHAT DO YOU RECOMEND OUT OF THE 2? AND IF U HAVE MORE INFO PLZ LET KNOW...I DID A LITTLE MORE READIN AND WHAT I GOT WAS BLACK TOP WAS OUT IN 97 THEN RED TOP IN 98 BOTH DUAL VVT-I EXCEPT THE GREY TOP WITCH IS COLOR BLACK BUT CALLED GREY TOP IT ONLY HAS 1 VVT-I.......AND TO ANSWER MY OWN QUESTION (IS THERE A VTECH FOR OUR CARS)...YES AND NO THE DUAL VVTI BEAMS IS BASICLY A TOYOTA VERSION OF THE HONDAS VTECH......I AM STILL TRYING TO FIGURE OUT THE DIFF BETWEEN THE DUAL BLACK AND THE DUAL RED TOP.......AND I KNOW ITS ONLY A DUAL UNLESS IT SAYS DUAL VVT-I RIGHT NEXT TO BEAMS
