Hey everyone

Ive been having this weird kind of noise coming from the engine bay.. it sounds like a girl screaming her lungs out or like a kettle really giving out steam.. I have a pretty much stock R33 S1 GTST.. Ive been trying to figure out where the noise is coming from.. this happened before I even put on my boost controller weird.. and still happens after I put the boost controller on.. it tends to happen once I hit around 4500 rpms even if Im free revving it on neutral.. kinda freaks me out because I keep thinking Ive hit someone.. LOL.. any help would be appreciated.. never encountered such a weird ass thing.. thanks everyone.

Some bearings can sound like that. Also seen a turbo that was scraping the inside of the housing make a similar noise.

Get your head into the engine bay and find out exactly where it's coming from.

but make sure you wear a helmet.... it could be the engine monster trying to lure u in :starwars:

I recently had a squeeling problem with the belt that goes to the A/C pump.And it only did it when the A/C was on.

What i did to remdey the problem was,get a dry cake of soap and with the car running,from underneath it,i sat it on the inside of the belt and made sure to coat all sides of it (belt).

The only problem with that is the soap will wear down fast,and,can get caught and ripped out of your hands.Also you have to be very carefull where you put your fingers.

the water pump seals are squeeky..

if lost count on how many na-33s ive replaced the waterpumpon to get rid of the mad scream at idle

for some reason its the non turbo ones ive had trouble with.

go to holden and buy some (coolant or water pump pellets)

they lube up the seals on the pump. if not you need a water pump.

      Might import a stagea

      By iamhe77 · Posted

      Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.

      My BMW E39 528i touring

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      Neil's R33 Gts-t Build

      By Duncan · Posted

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
