Is Turbo Ok?


Recommended Posts

I have a HKS2530, recently had a new wheel put in by Hypergear and they gave it the all clear. After putting some oil through it and spinning it by hand I have noticed there is a bit of noise, don't know if its usual or what. Video is below:

The sound itself wouldn't worry me too much but I can even hear it spinning for about 5 seconds after turning the car off from inside the cabin.

Seems to boost ok but hard to tell since I need to sort out a few boost leaks.

Any ideas, this normal with a BB turbo?

Should also note that there is no shaft play.

I think HKS wanted that turbo to be noisy. see the surge slots on the comp housing. as in the angle of where they are and how they sits. this thing will be howling very loud when air pass by. Been told by our engineer that this turbo's going to make lot of noise.

I sent the core to Garrett for bearing analyze and been told its fine before went ahead with the repairs. it should be all good.

Finally took it for a bit of a drive and seems good. Spools up quickly but yeah its very loud. Knock was reaching about 40 on PowerFC though so can't really test anymore until I get the GTR injectors in and get it tuned just in case.

    • Hello again, I have a 1991 r32 gtr that I’ve modified and dynod. The power it gave me was a bit disappointing with 533 wheel horsepower and 444nm torque on a dyno jet dyno. On a heavier dyno it would read to about 433 wheel horsepower. I say disappointing because it currently has : CP oversized 87mm pistons Eagle H beam rods Extended crank with the nitto collar  stock oil pump (nitto on the way) stock sump (leask sump on the way) Garret G35-900 single turbo  ^ With 26psi of boost (1.6 bar) 6boost v band manifold  turbosmart 60mm external wastegate Brian crower 264 cams tomei gaskets all around arp head studs  dual wallbro fuel pumps dw 1050cc injectors greddy radiator metal Intercooler pipes nismo thermostat  offbrand fuel regulator (tomei regulator on the way) ngk 7’s spark plugs (tuner refused to tune with 8’s for my car) Running on a motec m800  I know that running on e85 and opening the rpm to around 8500 instead of my current 7200 will also boost my power yet will it increase a lot or just slight because people like cardoGTR and andrew Hawkin from motive were all running around 600 wheel horsepower on the same setup as mine. Any feedback on what I’m missing?   thanks
    • At the moment still 8mm. 
    • I see what you mean !! 👍 so I drive with E85 AND E100 my cylinder head and full supertech with 270° camshaft and 10.25 lift this weekend I spoke with my mapper and he told me 10 ratio would be even better so I went to set up a setup with : 3.2l crankshaft from expensive spool import with a stroke of 91mm Nitto or IRP connecting rods length 152.5 mm and piston irp ratio of 10 after having the information near spool import the setup did not work because of the crankshaft which is 91 mm  therefore the assembly mounted in the engine block will come out 1mm high above the cylinder head gasket surface so I have to review the construction of the lower engine low IRP is Italian I am French I wanted to limit the costs because as they are in Europe I do not have customs fees to pay 🤷‍♀️
    • Update. Returned yesterday after a two-day venture driving it from Toowoomba, QLD to VIC.  Some bigger shots. However, this was a couple of hours into the rive at a driver reviver stop so you'll need to excuse the bugs across the front and the water from the storm we just escaped.  Looks like at some points both side windows had wind guards and were removed but left behind some kind of silicone or something (?). Any tips on how to remove this stuff appreciated. Noticed the handle for the hood release kind of just fell from its position with nothing fixing it in place to the mount. Looks like two bolts go there. Again, any advice is appreciated. The driver's seat is a Recaro seat in a fixed position (not mounted using the rails, which were in the boot). So the trip one was...more painful than necessary. I'm a bigger guy, so the seat belt was basically tight.  It also has a rip in the seat side closest to the drivers door.  Overall, I'm happy with my purchase.   Now I'm trying to navigate getting the roadworthy and registration here in VIC. Hope it will go well but I know the hood release will need to be fixed for sure.  
    • Your new rig ticks that box 😁 Just let me prep it first    180sx looks weird without it's stickers
