I am purchasing a 93 R1 Mazda RX-7 and I was wanting to know what mods I should do to make it more reliable as a daily driver(already tried a search). I know that I need a new radiator and fuel pump but what other mods would you consider to just help reliability. Car has new engine and turbos so I don't think it would need any of that. So any help would be greatly appreciated.

Thanks

Probaby the first thing you should do is buy a silicon vacuum hose kit for the car and replace all the stock rubber vacuum/boost hoses in the engine bay.

Also install a boost gauge.

 

and then a rad and a downpipe..

then you should be set

 

I second the silicone hoses...easily the most important thing on the car. As far as reliability goes.
