Hi i have a 94 Type Ra Wrx fitted with a Td-05 turbo unit. I was wondering what turbo would be best to upgrade to and what i would gain from doing this.

My car is fitted with
gems ecu
Fmic
full Decat system
Dump valve
Hks powerflow filter

The engine is the stronger Ra type unmodified internally

thanks in advance

 

TD05-06 20G
Your existing turbo will be good for 340+ BHP with all supporting mods. The TD05-06 20 G will be good for 380-400 bhp with all supporting mods.

 

Thanks for your reply. will the TD05-06 20 G give me any more gain in power? Or do i have to do other mods to get extra power? thanks

 

I think I answered this earlier but basically you need to do anything that will help air get in to the engine. eg ported headers and up-pipe. Also Walbro 341 fuel pump. upwards of 340/350 bhp you will need 550 cc injectors.
