recently bought a r33gtr and was wondering if turbos have been rebuilt or not? the car has been pretty well looked after and seems to have a lot of nice touches but nothing ott

one thing that makes me wonder is the hks evc has been set to 1bar, but warning at 1.25? if they were ceramic surely u wud set the warning a bit lower?

just wondered if anyone cud help or shed some light?

thanks ant

turbos

hi mate if your not sure of the history of the car dont take a chance, 1bar is max on standard internals,otherwise you could be unlucky and if it is ceramic it will shatter and could cause a lot of damage.





cheers simon

ye i know just wondered if there is any way of checking?
the car has been tuned by ''garage saurus'' thats why im thinking they may have been done, surely they wouldnt set this to 1.25?

No easy way. The lag with steel turbines should be greater but you would need a car with ceramics to carry out a comparison.

The only real way is to take them out and see (or run 1.2bar and see if they exit via the tailpipe).

would the rolling road road tell?
1bar ceramic = ??bhp
1bar steel = ??bhp

also if u take the downpipes of can u tell them? if so wat do u look for?

A quick search on the Register will tell you.

THe visual differences have been posted many times now.

But I can't quote them off hand.

Take the elbow off one turbo, and look at the "Nut" in the centre of the turbine. If it's 12 pointed, ie no flats, then they're ceramic.

No, that's a pic of the compressor wheels.

do a lot of them come over from japan with steels in or is rare?

i have had the same sort of problem but with more to it, car came with all under bonnet hks boost controll equipment but controller unpluged, ecu has big garage saurus sticker. so i pluged it in and had a go down at pod. pulled 13sec quater all three times but anoying rining sound from evc. with just filter and evc!!! not till finished and on way home that mate was watching boost gauge and it read 30psi!!!!!!! unpluged and left alone since. i was a very lucky boy and will leave that sort of thing to the pro's. when gaskets need changing i will get someone who knows to have a look for me.
