Equall lenght headers
3in full decat
RC induction with large KN cone
Simtek ecu.
Walbro255
Everything else standard
Im on a standard turbo at the moment but was wondering what people recomend as the best BANG FOR YOUR BUCK direct replacement for my standard turbo?????????????????? eg injectors,fuel rails???anything
ALSO Im new to subaru tuning but im picking it uo as i go along so if anyone has any ideas of any other things that i need to compliment my setup, i would be all ears
PS Wouldnt mind trying NOS

 

md321T 650cc injectors..

Simon

 

Cheers simon. can you get those parts?
what sort of power/torque should i get from that setup?

 

speak to mark @ Lateral Performance Ltd | Home for injectors and turbo

420ish bhp some make more some slightly less

Simon

 

As Simon has said matey.

I'm running 402.5bhp / 359lbft on standard block with a MD321T and 550cc injectors.
So with the MD321T and injectors 420bhp will be nice, very nice.

Talk to Simon about NO2.... Simtek and others allow dual/multiple maps.

if engines been built with uprated rods and piston should be able to aim for 450 surley?

 

the standard engine will take 450+.. forged depending on parts more still..

Simon

 

sorry simon a standard 2002 sti engine can take 450bhp how come?

so the bugeye sti is the best car to start with if you want to tune then as it has the 6 speed to start with to. and i guess the spec c is even better and stronger then?

you just have to be able to live with the looks and in all honesty they can be made to look quite nice

regards

 

the 02 engines seems to be able to take more than any other year, also seems to have the strongest gearbox as well.

not sure if i'd want to run 450 witout a rebuild, but the spec says it has been rebuilt with uprated intenals, so y not aim for 450bhp at least?

 

the 03/04 is as strong too

Simon

 

ok but i take it from 05 onwards they got weaker again?

 

the 2.5 is.. 400ish on standard pistons.

the 05 2litre is fine still.. 05/06 being the change over to 2.5 etc

Simon

 

thanks simon
