Nothing(V)an Posted November 8, 2006 Share Posted November 8, 2006 i bought my R33 (96 gts-t S2) from an auction, therefore i was unable to drive it before purchase, probably a big mistake but its done... anyway got it registed yesterday and having been giving it a bit of a thrash, whenever i hit a bump in the road (even potholes) the tail swings (little bit left then right), it swings more between 60-90km after that it is less noticalble. I drove it in the wet today, it swings a little more. never driven a turbo in the wet, was an experience (still in 1 piece). Why is this happening, is it normal? the tyres are in good shape Another problem i have is most times between 5-6000rpm my exhaust makes a popping noise (3 quick pops) sorta sounds like backfiring but not very loud? Lastly, im pretty sure the ECU has been modified as my car does not cut out a 180, could this be related to the other problems. so im thinking i need to take her in for a tuning, anyone know of some good places in brissy? cheers, oh and suspension is very hard, should i upgrade it?

SLYLNE Posted November 8, 2006 Share Posted November 8, 2006 popping noise would be your coil packs. had the same problem not long ago at the same rev range. as for the swinging around, get wheel balance and alignment done..remember gtst is 4WS..so get front n rear done. cost about $150odd at pedders. hope that helps..

mad082 Posted November 9, 2006 Share Posted November 9, 2006 the ecu may not have been modified. your speedo may just be out. on the dyno my speedo said about 195 when it hit the 180kmh limiter. the popping my either be coils or spark plugs. as for the tail of the car moving, i'd get a wheel alighment done and get all the suspension checked. there may be something broken or worn, or there may be a problem with the hicas system.

SLIPPERY Posted November 9, 2006 Share Posted November 9, 2006 re swinging: you sure youre just not lighting up the rears with the lsd locking hard and both wheels losing traction, hence sliding around the palce ...im not sure how familiar you are with cars Link to comment https://www.sau.com.au/forums/topic/142521-is-anything-wrong-with-my-r33/#findComment-2654448 Share on other sites More sharing options...
blind_elk Posted November 9, 2006 Share Posted November 9, 2006 ... got it registered yesterday...im pretty sure the ECU has been modified as my car does not cut out a 180... How on earth do you know this? Link to comment https://www.sau.com.au/forums/topic/142521-is-anything-wrong-with-my-r33/#findComment-2654705 Share on other sites More sharing options...
psybic Posted November 9, 2006 Share Posted November 9, 2006 I have an idea how he might know that.... not the smartest idea if you are having problem with handling at less speeds... Speed cut isn't set at exactly 180km in all ECU's... I don't know about skylines, but when exploring remaps of ECU, I was forwarded the 300zx data, speed limit was 188... slight variation in wheels or speedo calibration could easily see a few kms either way. I love the old, throw it on a dyno for a tune... still not sure how you expect the "tuner" to alter data in the ecu if its stock, which it probably is otherwise you would probably know about it.

NickR33 Posted November 9, 2006 Share Posted November 9, 2006 I get 195km/h down the straight at Sandown ... which is redline in 4th or about 5,000rpm in 5th (speed cut) ... BTW its way off past the 180km/h mark on the speedo but I have a peak speed function on my defi unit ...

RPR33 Posted November 9, 2006 Share Posted November 9, 2006 "Im pretty sure the ECU has been modified as my car does not cut out a 180..." When I got my series 2 I also noticed it would go off the clock and just keep going, so I checked the ecu and discovered a ksp tuning label on it!! Still trying to find out what has been done as far as I can tell no speed limiter and it was a pretty aggressive stocky also no response to the solonoid earthing for ''full time full boost'' Link to comment https://www.sau.com.au/forums/topic/142521-is-anything-wrong-with-my-r33/#findComment-2655942 Share on other sites More sharing options...
MBS206 Posted November 9, 2006 Share Posted November 9, 2006 Rear wobble is most likely a mm or two of toe out, or quite a few mm toe in. Mine used to shake exactly the same. Found out the car was running 3mm rear toe in. And for my all 4 tyres aligned, and suspension/driveline checked, it cost me $50... Don't know why on earth people think 4WS costs more :S My wheel alignment specialist reckons the newer and more "intricate" they get, the easier they are to set up.

yummy Posted November 12, 2006 Share Posted November 12, 2006 (edited) yep popping noise is probably misfiring, caused by cracked coilpacks or worn spark plugs. also when i had my stock ecu in speed cut was at 195 on my nismo 300kmh speedo, however that is probably inaccurate due to running different diameter wheels to stock..
