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 .

cheers, its this part number 714568-2 and the comp cover is the .70

i just wasnt sure where to look as they arent labeled gt3540r on the garrett site anymore.

cheers

awesome turbo ! i have one on my rb30det - makes full boost before 3500 16psi

hey there, my setup will be very very similar to yours but im going to run more boost and some giggle gas for good measure

ill let you know how it goes. wont be put together for a few more months but have most of the parts now.

wind up the boost, come on you know you want to

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.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
