 I bought my GSX new back in 1998. I 
made some modifications over the years 
to the exhaust and intake. Strut tower 
braces front and rear help to cure the 
car's roll during high speed cornering. 
There are differences in the 4G63 
engine from the 1G to the 2G, mainly 
the turbo and intake manifold. The GSX 
is the best model because of the AWD 
and 4G63 engine. The non turbo models 
have to deal with a Dodge Neon engine 
that is very troublesome.  As with any 
car, follow the maintenance schedule 
religiously and you won't have a 
problem. I've used synthetic oil since 
it came home, and I've had no valve 
issues or oil squirter blockage that 
causes the 4G63 valve click.
