200sxRb20

yeah, the video was abit misleading sound wise, but didnt hurt to check the belts first just incase it was something simple like that.

ok so finally got around to working on it. exhaust manifold gasket checked out, manifold to turbo gasket had crack in it, but that wasnt the issue. broken blades(see pics). usually id be upset about a broken turbo, but just using this as an excuse to put on the t3.

thanks for the tips guys working on checking the gaskets on the mentioned areas today. might use this as an excuse to put the larger turbo on..

lol, yeah the 02 sensor is in, cant say that ive made that mistake before. cant really pin point the area the noise comes from, will try some more today as well as check the turbo out. has no shaft play in it, i have checked that out, but ill check the gaskets and such today.

heres a vid or two of the noise, hope this helps out. http://s25.photobucket.com/albums/c73/vg30...nt=105_1583.flv 105_1582.MOV

ok, now i have a new problem and will do my best to describe it. engine is an r32 rb20. under load, usually around 3-4000 rpm I get this high pitched whistle/noise. it starts off low pitched but rev it abit higher and it gets..higher pitched..yeah. cant seem to figure out what it is. fresh oil change, checked all the couplers for the front mount intercooler piping. checked as many places i could for some sort of leak that would give me an indication of why its doing this. also the exhaust sounds abit different like there is a leak somewhere, sounds more like an old truck now and every now and then when shifting or rpm drops i get a pop out of the exhaust, usually abit of fire. it tends to want to just die on me as well. starts fine but from time to time if i dont hit the accelerator pedal, the rpms will just drop until it dies. any ideas? here are a list of my mods incase something might be related. the engine has appx 60,000 miles on it(around 96,000 kms?) ARP Head Studs, GReddy 1.2mm Head Gasket, GReddy Timing belt, Fidanza adjustable cam gears, Hybrid FMIC and piping, Turbo XS BOV, HKS pod filter, 3" exhaust with Fujitsubo NGK axle back GTR fuel pump Koyo radiator w/ dual 12" fans, GReddy EManage, GReddy Profec E-01 ,GReddy Auto Timer, HKS Hypermax D coilovers, front camber plates, Cusco front strut bar, Cusco front tension rods,

Lots of people here in the states arent really liking the new gtr body, but I actually like it alot. very sexy and finally a gt-r thats coming to the states!

hmm, could be few different reasons why the second blew, but you mentioned you got it from a wrecker so thats my first indication. turbo was probably in bad condition to start.

diggin the pics man, the second pic makes the car look mean

its pretty much exactly the same for the rb20det. just did it today. when I took the cover off there was almost no solder holding the contacts in place, which explains why it would run good sometimes and shitty other times. thanks for the tutorial. saves me and the guys up here in the states alot of cash as parts for the rb engine are harder to come by up here, and not everyone wants/can upgrade to z32 mafs. Thanks again

i plan on replacing mine with a z32 soon, but not until i run put on all the parts ive collected to need it. Right now i am still on stock injectors/turbo so I dont think I need the z32 maf just yet but once again thanks for pointing out that DIY I will post up if thats the issue.

i took a look at the diy thread you mentioned and opened up my maf and noticed that almost none of my connectors were touching properly. so Im assuming this was my issue so maybe it will be yours as well.

having some simular issues. let me know how it turns out for you

unplugged the 02 sensor, didnt seem to make any differance in the idle at all. bad 02 sensor?

I will try unplugging the 02 sensor today and see how that works out for me. thanks for the reply mate
