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.

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!

      Pillar gauges

      By MBS206 · Posted

      See, that button sounds like perfection Duncan! My eyes really don't like light shining at them from a dash when I'm driving. Being part red colourblind, I've found for most cars that I can change colours on, I set everything to red, so my eyes see the elast amount of colour! I miss normal gauges in cars

      bro, knowing the Japanese in  the 90's, i wouldn't be surprised if they shared components across their model lineup.

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Maaaan so many "little" things  i rly hope my old RB20 would be "ok" and not too bad. I try to learn what and what not do i need. I look at crossmember at it looks different...even parts numbers are different. Wiring and all that i rly do not know...yeah someone mentioned the speedo thing. On that yoke clip. I rly do not know what can and cant be done "custom" so that is why iam asking to know and not be suprised 🙂  I know what it looks like

      By GTSBoy · Posted

      Oh, there's also the gearbox crossmember which will probably be different between the small box and the big box, and the wiring loom will probably need to be modified, because the plugs for the switches etc, will probably be different. And I think the speedo on the small box R34s is from somwhere stupid, like the diff, possibly, so you'd need to work out what needs to be done about that (assuming it is different). I think the thing you need to realise is that the front end of that yoke is a large hollow tube with splines on the inside that mates with the splines on the box's output shaft. It is a dedicated thing - not available "aftermarket". They were made to suit that box, by the car's OEM.
