Its actually just a VTI (not vtir, that's for EK's). SOHC VTEC. Which means its EFI. Do not buy a carby.
FYI, Sohc vtec are amazing to turbo. A lot easier than the Dohc vtec's (B16/18/20 F20C).
Yes I agree (@Rekin) DOHC > SOHC Vtec, but dude just wants a car (And by the sounds of it, can't be a powerful one by what dezz says), and the VTI would be a lot more reliable than an old carby. Its worth the money just for a car. Not worth the money to mod them.
And yes what billy said is true, the VTI was a more luxurious version compared to the GL/GLI.
