burtysbugeye

Ok i have a bugeye wrx, ive finished with the cosmetics of the car, so i now want to spend money on getting more power from it, ive got a H&S downpipe and centre pipe fitted and thats about it, it hasnt had a remap yet. What other things should i do to it before the remap and what BHP should i expect, also if i was to change the turbo to a bigger one, would i need it mapped or would it been fine just fitting it with out any problems, and is the standard turbo on the car now a TDH04 and the sti one a TDHO5, just want to no what type i should be buying.

Few things to consider:

K&N/Green Panel Filter £40
Walbro 255 Fuel Pump £80
NGK 7's Plugs £50

The remap will cost you circa £700, as the first one will include your license.

I would lOOk at doing the headers & up-pipe too. circa £400.

If doing any substantial mods, i got them fitted on the day or just before the remap and limped ( < 3000 RPM) to the mappers.
