I know most people here use HKS GT25s but Im about to go down a different path and try the TRUST route :sly:

I was wondering if anyone here can tell me how different specs of TD06 would perform on a RB25DET, in particular the Compressor housing specs between the 17C, 20G, and 25G

The exhaust housing is pretty straight forward: bigger, more power, more lag

What about the the differences between TD06, TD06S, TD06SH and TD06SL2?

The TD06-17C are usually used on high powered SR20s but anyone every tried them on RB25s?

hey got a tdo6 20g with 8cm exhaust housing.. internal wastegate.. you can get 8cm, 10cm, i think 12cm not sure about 14.. but there is a guy with a 16cm i think.. its rob77 he mite post up details. im not sure about any power ratings.. dunt even know about mine.. so if some one could help out please.. im going to convert it to external wastegate i think.. just for the noise (as its a drift car and need all the wank value parts :)) this is going on a rb20 and hopefully isnt too laggy. there was a jms car running a internal wastegated tdo6 19c and he made 306rwkw on 1.6bar with special fuel and ran 235rwkw at a dyno day not sure on boost/fuel etc tho. did run a 11.3 i think on slicks also.. if that helps. oh and that was on rb25/microtech etc etc

How much power you after...a L2-20G is equivalent to a GT2835, a SH-25G maybe too powerful if you want to keep it a street car. I know an Evo with a TD06SH-25G will make 650ps @ 2bars.

Thus the question which is constantly asked, why go L2-20G when the factory Evo turbo can run high 11s and make just as much power (~400ps), same with why go T67 when a TD06 can make just as much. Depends on the car, setup and tuning.

Once my engine was rebuilt with forged pistons we ran up 366hp @ 1bar on a td06-20g 16cm^2 exhuast housing. I had the exhaust housing and dump pipe ceramic coated whilst the engine was in bits and I get full boost by 4300rpm. Do a search on "average power" as that thread has a copy of my dyno sheet. Its such a wild ride now, it goes from ~160hp to ~330hp in the space of 1000rpm. I'd like to try higher boost settings, but without bigger injectors, a decent exhaust manifold (its all bolted onto the stock one) and some cams I dont think its worth it. Only fault I find is the lag, a ball bearing turbo would probably come on boost about 500-800rpm quicker for the same size.

Is that a hunch or something that Steve SST etc has told you. My thinking is that it wouldnt be that dramatic, could be wrong, probably am, just interested to know. In the Garret catalogue, what does the 16cm housing equate to, something like a 1.12 or bigger isnt it?

Buster vs B-Man would be a more vaild comparison, both have ~325rwkw peak (Buster 328, B-Man 323). Buster's TD06-25G/10cm rear had more all over the curve, boost coming in 1,000rpm earlier + a higher peak. B-Man's 3040/1.22 A/R is capable of far more - his is only in initial stages of development whereas Buster's was at it's peak.

(I should just shaddup and let both of those guys post here, but I blabber too much)

have a td06-19c internal gate turbs, has been flowed with garret comp wheel (the std comp wheel was shagged) even so the std wheel is very ugly in its design, and tiny too. Havent actually ran this setup yet but getting close (rb20)

    • Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!
    • I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).
    • At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself 
    • I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad. 
    • The water pump is know to leak as well. So if the coolant is low checking that first as well as hoses.
