Hey guys,

Very new to the forums, love what i see already in the SAU community..

Just need some urgent help with a turbo question...can't find out much about this problem..

I have a 96 33 gtst S2 and it has blown the compressor wheel into pieces on hard boost..I was wondering if this has Happenned to anyone else could they Let me know what I should do.

Would some of the pieces from the ceramic compressor wheel gone into the engine? The pieces that I found were in the compressor housing and in the intercooler when I removed and shook, there were no fins left on the compressor Wheel at all. I just hope I don't need a new motor....

Also what turbo would you guys recommend for me that is a direct fit onto the rb25 without modification? I'm looking for

-Turbo with anywhere between 350 and 500hp rating as is a daily driver

-steel wheel instead of ceramic

- an easy DIY replacement

-rough ball park figure to fix as I'm in desperate need on getting back on road as I cannot get to work at all ATM. ( cheap as possible please....)

Also would a loose vacuum line on the EBC have cause all this mess? I found the Line that goes to the throttle body has come off when the turbo blew....

Whoever can help me on this would be great and all help is greatly appreciated!!

Cheers!

mate your gonna get told to search here. all the questions youve asked have been answered a million times.

easiest replacement is a highflow turbo. bout 1000 from hypergear/gcg. google is your friend here.

best of luck with it.

you will also need either a piggy back ecu or fully re mappable ecu.

Ok so all I need to do is replace the turbo

, no need to check internals???

I would like a turbo with minimal lag and decent hp output.. ( gettng 2 used to this setup) I have a little cash to play witty...

if the comressor wheel blew then replace pipewore/intercooler etc and replace turbo

if the turbine wheel exploded then you should be ok to just replace the turbo

caused by excessive boost on the ceramic wheel. they do not like much over 13psi or any heat at all

but as stated above this has been answered to death on this forum

Since you are in Melbourne go to see Hypergear for a turbo replacement, they high flow or make bolton turbo, I'm sure he can knock some thing up within your budget then go to see Chequred tuning for dyno tune.

make sure you check the throttle body pipework too

ive seen busted plastic bits end up at the throttle body so be sure to check there as well

if its gone into the engine its too late anyhow and it would be stuffed by now

all you can do is check the pipework and make sure theres no bits left lying around

for direct bolt on and best performance GCG hiflow

send them your old busted one

then send you back a new one highflowed and its a direct bolt and looks the same as the std turbo

but you still need fuel pump, ecu, frount mount intercooler to get it working properly

you could change just the turbo and drive it normamly but most poeople when they change the turbo wind the boost up and complain when it misfires etc with the standard ecu so just do it properly

The GCG highflow is something like $2500

Hypergear is more like $880, and I prefer his service every day of the week. I have heard extremely good feedback re his highflow.

OP please remember that if you change the turbo to something other than stock you will need a tunable ecu and a tune at minimum (to make it work safely). However, you will then be limited by everything else that should have been changed.

Here are your two options:

- replace the blown turbo

- replace your intercooler with a front mount kit (you will want it later anyway)

Do this and you will be back on the road ASAP, provided that you clean everything well and no damage was done to the motor (no point fretting on it just install the parts and see what happens).

OR

- Have turbo rebuilt by Hypergear to whichever spec you decide (normal hiflow profile works well and is cheap)

- order a adaptronic ECU from Hypergear with your turbo, you will get an awesome discount buying as a package. this ecu will also mean you don't need an AFM anymore and dont need to buy a Z32 AFM. Get the car tuned by the same tuner Hypergear uses Chequered Tuning.

- replace intercooler with front mount

- ensure you have a 3" turbo back exhaust

- put a 3" metal intake

- install walbro fuel pump or similar

- install upgrade injectors if seeking over 220kw (550cc minimum but recommend larger)

The second option is likely to cost you about 5 grand but will be rewarding once done. If you cant afford the 5 grand stick to option 1 and just fix it.

Part and parcel of modding a car.

From memory Birds got 260kw from a Hypergear SS1PU using stock intake pipe, airbox and cooler pipes. Running a full 3" TBE and return flow intercooler IIRC.

nothing to say the OP couldnt do the same... I would recommend the 3" intake though.

Thanks guys for all your feedback!

I forgot to mention it has an aftermarket Greddy FMIC, 3.5 inch from turbo back, but standard computer, and a Bosch fuel pump. The guy I bought it off had dyno sheets for 191.1kw atw. It seems to high for just those mods... Ohwell...

At the end if the day all I want is it back on the road ASAP with a reasonable priced turbo and reasonable power... Maybe 220kw +

Thank you again. Much appreciated fellas!!!

One more pain in the ass question... Does anyone know exact specs on the stock turbo?

Cheers!

    • You have found the problem. The wire from the switch to the HB is shorted to earth. Now you have to physically find it and replace it. It won't be the switch, although following the steps above (and yes, where you ask, that is the light switch on the RHS of the binnacle) will rule it out for sure. Or not, if perhaps the switch has melted. But there's no route to earth inside the switch, so I can't see how it would.
    • I did read your post, a few times actually.    Done. Followed this step. [Negative probe should be on the cars chassis. Positive on the wire.]   Did this partially.. now that im reading this over, i only unplugged the LED lights. [Start as said above by unplugging everything (unplug the lights, and switches.] When you are talking about the switch, you're talking about the knob thing on the right side in the drivers seat right? If so, i need to take that apart?  [Now at the switch, there is a wire from the fuse, to the switch, so out your positive on that terminal. It should read open circuit. If it reads something, especially a stupid low value, the short is somewhere between the fuse and the switch.] At this point are you referring to the connector by the headlights?  [If that's fine, now put the positive probe on the wire that goes to the headlight (at the switch plug). If it reads stupid low, the fault is from the switch, to the headlight.] Did this. I can confirm that the LED lights aren't the issue [Another quick test, is take the whole LED light setup from the left, and plug it into the right side, does it still blow the fuse? If you put the right hand side led light setup on the left hand side wiring, does the left hand side wiring now blow?  If the blowing fuse swaps from right to left doing this, your LED lights are the issue.]
    • Hey was wondering if you ended up installing the R33 GTR speed sensor - I found one too and wanted to confirm it's a direct swap into the R34 6 speed?
    • After 23 years of owning a Skyline, finally had the latch go.  Followed this guide,  works like a dream again. Great Guide đź‘Ť
    • Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄
