individual throttle bodies

Hi I'm in the process of a ITB conversion onto my 1UZ Engine is stock apart from link ECU, headers & a twin pipe 2.25 inch mandrel exhaust with a cross over and of course the 50 mm ITB's. I'm thinking that the standard blue 250cc injectors will need to be upgraded???? Can anyone advise on this...

Hi, I'm using the above engine for a project, and looking for a supplier preferably in the uk for a set of ITB's. any information on additional parts like exhaust manifolds would also help. many thanks.

OBX ITB for $840 I'm REEEALLY tempted... :( http://www.rsaperformance.com/obx-itb-individual-throttle-body-toyota-1uz-1uzfe-v8.html
