4g63T Swap

I CAN GET a 4g63T Engine, ecu, etc. and I have people to install it. This is doable right? I got some people saying its not, but plenty of people waiting to do it. What is going on with this? Or would I be better off just turboing and building up the 420a(pfffft) that is in my 95 GS?

its practically impossible to put a 4g63 in a car with a 420a everything is setup different and you will pay less to trubo what you have now. you can run low boost like 7 lbs on what you have now if you dont beat it all the time and then buy pistons and rods and all that good stuff and it will be fast i have a friend who got a turbo kit from turbokits.com and hes running 7lbs on stock bottom and hes running low 14s.
