hi i have a sti 5 type r so far i have fitted a 3" decat exhaust, k&n panel filter and a dump valve.i am told my car should be running around 300 bhp.i am thinking of gettiing it towards 350bhp. would a set of perfomance headers,up pipe,uprated fuel pump and a remap do this and can my engine handle this the car has done 60k miles

 

I reckon that 350 bhp would be about as far as you could go on standard sti internals (to be safe) and then the limiting factor would be turbo and injectors.

Not sure if the standard ihi sti 5 turbo can make 350 or not
I think sti 5's run 440 injectors so you may need to upgrade to 550's to be safe.

 

I've have the same car mate.
To give you an idea, mine is running 335bhp & 333ftlb with the following mods.
decat down pipe, blitz nur spec, walbro pump, green panel filter, harvey smith ported headers & up pipe then an Ecutek remap.
Just don't run your car with those mods without it being mapped for them or you'll be looking at a rebuild in no time.

 

Hi just wanted to ask.
I have a impreza wrx 2004 and I have stage 2 clutch, full decat exhaust pipe since then every time the car goes over 5000rpm the engine check light comes on and the code is 171 its has some thing to do with lean fuel and the other code is 244 again some thing to do with turbo wastegate solenoid. can some one please tell me what do I need to do to stop this happning

 

thanks mate

my car is a fresh import and doesnt have much history so i think a service is needed just be safe

also i have that heard andy forrest is the best person for a re map has anyone been and had him re map there car if so whats involved?

 

ned to idealy get it mapped if you decat a new age, but it also needs a cel (check engine light) fix to prevent light coming on. first port of call is get it ona dyno and make sure its not runnign lean etc.

 

I used Andy F for my first map & you won't go wrong with him or JGM.
Basically he hooks your motor up to a lap top & you go out the road. He'll tell you what sort of runs he wants you to do while he makes adjustments to the ecu settings. He'll check your fuelling, check for det & overboosting.
Then he'll do a couple of power runs & give you a bhp figure.
You'll end up with your car pulling harder from lower revs & generally feeling a lot more driveable. But the big advantage is it's running safely for your mods & whatever grade of fuel you are using.

 

i used jgm for mine and the car runs great (jolly green monster) nice guy and he comes to you too!

 

For 350bhp (well anything about 320bhp really) then a fmic is ideal on a classic, if you wanted more power then you will need bigger injectors, turbo (vf35's are ideal), your clutch may well suffer, a dry panel filter, uprated fuel pump and really some uprated brakes.
