My 2 cents here would be, give the RA28 to someone that would make better use of the vehicle...

The 1st gen Celicas have a horribly flexible chassis and, without massive chassis strengthing mods (like this), are absolutely pointless for any motorsport that benefits from having a rigid chassis...

The 1JZ conversion is not that much more complicated than a 1G conversion, and the 1G is equally as bad for "alot of servicing needs"...
