Need Advice: Bt Head + Svt Bottom

[Reed1]

Dear Toyota Sifoos,

Do I need to fabricate / customize timing cam pulley, timing belt crank pulley, or any other engine mechanical to make the BT Head + SVT Bottom hybrid? If I'm using BT wiring and ECU, as far as I know, it should be a direct swap right? Or, should there be any different in the timing belt length / width / teeth etc.

Please advise....

Thanking you all in advance.

bt and svt timing belt not the same. If i remember correctly, Bt 110 teeth and svt 111 teeth. Why u want 2 do this? Buy a bt engine kosong event better.
