R32 Issues

[old_mate]

G'day

Mate of mine took me for a strap in his R32 GTS-T tonight and it has some serious issues. I am not an expert on the Nissan engines but when this thing hit 4 grand it felt terrible. It has a pod filter, exhaust and blow off valve, the turbo was boosting somewhat (as it would vent via the blow off valve) but the car went nowhere. It also keeps displaying a warning light on the dash, we are pretty sure it might be an exhaust gas temp warning light? looks to be roughly 2nd warning light in from the right. light will also randomly show at idle, always flashes under load.

is the sensor stuffed causing ECU to pull fuel/retard timing under boost, or does it sound like the turbo is stuffed? History of car is unknown, its a recent import

many thanks

Pull the passengers kick pad off and check for an aftermarket ecu.

If its the stock ecu then look at the cat, its most likely stuffed.

definately no aftermarket ECU, although it did come with an aftermarket AFM harness which didnt work with the factory one so that has been replaced. I'd say this car has been messed with

futher research has me led to beleive the warning light is just that, its not sending anything to the ECU. So best bet would be have the cat replaced, then go from there. Would having the cat blocked make it feel so slow, or could there be other issues?

dude i got a similar prob but no warning light appears.

mods are:

catbak exhaust, pod and bov

ever since my manual bst controller was installed car running shit and wierd noise appears from the exhaust

the car doesnt really pull anymore above 4g but my boost guage is showing .7 bar then droppin...

does it miss, or just lose power when it boosts? can u explain what u mean by feeling terrible?

[RB32]

people seem to think that there might be a leak in the boost controller installation because its only happened ever since it was installed.

might sound confusing but last night i took for a spin and wen i flat foot it from the start it shows full boost to .7bar then drops 2 .6bar and it climbs in the rev range slow (1st and 2nd gear)

but if i was 2 put my foot down 3 quarters of the way until it hits 5000rpm then flat foot it, it runs perfect.

so in other words in only happens wen my foot is all the way dwn startin from 3500rpm.

confusing yeah lol i dont know whats happening....

regarding my mates car, its like its not boosting at all. It feels terribly slow. My EL XR6 would whip it

i suppose all he can do really is get a new cat and take it to someone who knows what to look for. This car has definately been messed with, there is evidence of an old boost controller being installed (no longer there) and we basically have no idea where to start.
