Hi guys, ive got a pretty good idea of what i want to do on my GT4, but what do you guys sugggest out of the following?
1. HKS intake, HKS BOV, HKS Camshafts & pulleys(Which i already have), HKS silent power exhaust, a'cheap' downpipe & flexi iridium plugs, boost controller, new leads etc... 2. Blitz intake, BOV, NurspecR exhaust and the rest as above 3. mixture of above Suggestions welcome!  By the way, im thinking about 'Aussie XS' (I think thats what its called) downpipe & flexi, anyone else got this, is it any good??? This is the one most GT4's i have seen have on them, but i've seen a company called Hyper Sports who do cheaper downpipe and flexi, not sure which one to go for (Apparently the aussie one goes better with the Blitz??) -------------------- 1996 UK white ST205
1998 UK silver ST202  Nothing is fool-proof to a sufficiently talented fool!!! |

Why do you want to waste $ on a BOV when the GT4 already has a perfectly good one fitted as standard

All I can tell you is my spec.
I run a HyperSports downpipe, iridiam plugs, HKS intake, and a flexi back specNUR. I have no EBC currently. I also run a Blitz BOV because I blew the plastic stock one to bits....... Cams probably aren't worth worrying about if you're not going past 300-320bhp (youll be needing a mappable ECU at that point). Be aware that if you go too 'free flow' on the exhaust, the stock wastegate can't cope and you'll get overboost leading to fuel cut. -------------------- JDM ST205
Blitz Spec NUR Exhaust, somewhere over $1000 Needing another one 18000 miles later, bloody annoying. |
