New Owner of a 1986 Tarago

[Rayzrider65]

Hi there

I have just bought a 1986 tarago,2L-5 speed.

It doesn't have power steering and I wonder how difficult is it to fit,

and I want to put some mag wheels on it,preferably 15" does the corolla stud pattern fit?

And lastly the 2litre motor has a carby,which I think isn't all that good,so I am wondering if I can 1. change the motor to a twin cam,also what other carby will fit .

thanks in advance. B)
