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:

      Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA

      All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.

      roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.
