ok gents my 2.5 sti hawkeye is standard what do i need to bring it up to PPP level?

prodrive quote £1600 for the pack without fitting.....

as far as am aware its just a fuel pump, remap, intercooler hose and a back box...

do i need a prodrive cat etc...?

 

If it were my car, I wouldn't bother with PPP (overrated)...


If you have a friendly MOTer, then:-

Full straight through decat d/p (much cheaper and freer flowing than a genuine PPP sportscat!)
Walbro 255 or HS342 fuel pump
Remap.

Not sure by which method a Hawk's OEM ECU can be remapped (EcuTek?), but if so, it will come to way less the 1.6k - even if you get the d/p and pump fitted by a specialist! More like south of a grand.

Get one of the mappers on here to do the remap and you'll get maximum bhp/lb ft/drivabilty with optimum saftey.

 

thanks for the feedback Joz not to happy about going down the decat route as my old WR1 had this and the exhaust was far too loud!!!

 

Okay then, what about a decent 100cell sportcat that is cheaper than a PPP one?!

Basically don't necessarily get hung up on the PPP hardware (if it means the PPP stuff is expensive), is all I'm saying ...

 

^^ totally agree, mine is the ppp version and it has all been taken back off lol, straight through exhaust ( can get these to be loud or quiet just ask them to put a resinator in there if you prefere the quiet route) new pannel filter and remap, car has made 345 bhp with just the bolt on mods, personally i agree with joz ppp is overrated especially when u can get much better power output, better delivery and the parts are cheaper and most of the time exceed the prodrive counterpart

 

It's not the presence or absence of a cat that makes it quiet or loud, that'll be things like the resonators in the exhaust. Try Mongoose or Revolution if you don't want it to be loud.

Decat/sports cat exhaust, filter, Ecutek map with Racerom will get you circa 350 bhp and 380-400lbs torque. Just make sure it's mapped by someone who knows what they're doing as Hawks with std pistons won't tolerate too much boost!

 

Although the above is perfectly true - i.e. it'll be the design of the back box that's chiefly responsible for the volume - a less restrictive d/p and/or centre section with fewer/no resonators, will add to the overall volume. Albeit not by as a greater degree as the design of the back box, alone.

 

I had a full miltek and that wasn't too loud at all and that was no cat

 

Thanks for the replys guys am thinking a sports cat and a back box change will do the trick
