I really wanted a t66 but have been offered a gt3540r 0.82 at a great price so am going to go with it.

What i want to know is how im going to identify the turbo as from what i know the compressor housing and exh is similar one most of the other similar sized garrett turbos.

Any information would be great. Have done a big search but come up with nothing.

SirRacer,

The standard GT3540 (aka GT35R or GT3540R or GT3582) uses a 61.36mm, 56 trim compressor wheel in a 0.70A/R compressor housing and a 62.32mm, 84 trim exhaust wheel, in either a 0.63, 0.82 or 1.06 A/R exhaust housing.

To identify the turbo, check the code on the Garrett ID tag on the core. If it says “706451-15” it is a GT35.

The exhaust housing A/R is cast into the side of the inlet to the exhaust housing.

Cheers.

My lists for the GT35R or GT3582R as Garrett now call them show the cartridge (CHRA) number as 706451-5 . The complete unit part numbers are 714568 -1 or -2 or -3 depending on which AR ratio turbine housing it has ie 1.06 , .82 or .63 in that order .

So if you order a GT3582R in .82AR ratio turbine housing its part number should be 714568-2 . Confirm that it has a 68mm 84 trim turbine and 82mm 56 trim compressor of the 6/12 blade GT family . The compressor cover should be a .70AR ratio TO4S type .

Cheers A .

Hey

I am running a stock bottom end (cast pistons) so 350rwhp is kinda enough for me for now.. with the 3 litre its all you need for the street. I guess i could go up to 22psi and make shitloads more but thats when i can afford it and get sick of the power.

I note in your sig... 350rwhp on 16psi.. any more power and its a waste.

As your not after more would you consider dropping to the GT30r? Or do you think it would pose greater traction problems?

Probably not. It drives pretty good atm. Pretty happy with the way its going. Dont really have a big desire to go for more power at the moment. But that will change when im ready to go to the track.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
