Hey guys have found what turbo i want for my rb20 but there are 3 differant types of the 8cm exhaust housing one, they are:

TD06S-20G 8cm

TD06S L2-20G 8cm

TD06SH-20G 8cm

Going too be buying one soon and would like to know the differances, names of the turbos were taken off the greddy website...

TD06S-20G 8cm

TD06S L2-20G 8cm

TD06SH-20G 8cm

Basically the TD part is the turbine, the 20# is the compressor

So the TD06SL2 has a different exhaust wheel to the TD06S, from the dyno sheets i have seen there is no difference in response or power. The TD06SH is bigger again and would most certainly be laggier as it is the exhaust wheel used on the T67-25G and TD06SH-25G

Yes the nice Trust spec turbine is the "TD06 SL-2" version . More open blades and I think from memory 11 blades rather than 12 . It's actually slightly smaller in diameter than garden variety TD06 turbines but works quite well for its size .

Mobs here in Australia can build you turbos based on that turbine , GT Pumps is one . They also usually stock the three trim sizes of that compressor family - 16/18/20G . Don't quote me but TD05/6 may be based on the same center section .

The main challenge , as always , is getting the flange to suit your exhaust manifold . Trust Greddy sometimes use a 3 hole pattern but I'm sure I've seen Mitsy (MHI) turbine housings with T3 sized mounting flanges on them .

Whats the bite for a Trust TD06xx these days ?

L2 is the pick of the bunch....it is the turbine that comes in the Greddy kit :laugh:

Have you seen a straight TD06 vs the TD06SL2 comparison? Interesting to read if others experiences vary.

I dont think there is really much in it. vsute has an R32 GTSt that is near identical to mine. Same ECU, same injectors, same tuner, same dyno and both completely std RB20s with cam gears. Our graphs are identical except for the fact our cars run different diam tyres so the dyno sheets look identical only just offset from one another.

He runs the L2 i run the norm TD06, i dont think its even a TD06S, well not according to the tag on the compressor cover. So i wouldnt lose any sleep over makign sure its an L2 version.

I know its only one expample, but its a pretty controlled example. Our cars made within 2kws of each other at the same boost level.

260rwkws at 18-19psi. I have run 22psi in it, but i dont think there is much more power in it. Shit load more midrange, but ultimately about the same top end power

The red line was with some cams i tried, the amount of ignition we were able to wind into the engine suggested that the cams were simply too big for the little RB20 with a small TD06 8cm on it. Cams were Apexi 260/8.8mm

The std cams work pretty well, with over 240rwkws from 130km/h to 185km/h

I have no idea. The workshop i use for tuning is doing something right as he gets great results out of std cams. My car was on Dr Drifts dyno and i think it made 20rwkws more then any other std cam RB20 he had run before. Not sure if it was 20rwkws, but was soemthing like that. That was almost 2 years ago so he may have seen some more decent RB20s come through the workshop.

But i have to say if i was going to try cams it would be the Tomei 256 jobbies. Some also have good results with the HKS, but i just sold my set as i was not willing to spend the dollars experimenting when what i have already works well enough for me.

LOL, did i ramble enough? :) Real answer is fark knows :) It woudl be interesting to see you do a proper before/after comparison on the same dyno and same tuner. It seems Dr Drift got good reslts with the Tomei....but more cars getting the same result would be nice :)

I say its the pick of the bunch because you get the L2 with the manifold pipes etc etc for the RB20.

I have seen greddy kits come with turbos not specified for the kit, however, trust seemed reluctant to do such a thing.

However, yes looking at the specs on the turbos from greddy they are a much of a muchness. :ermm:

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
