Tdo6 Vs Gt2530

[Wheezy]

Not sure what you mean by "Wich version, the standard, or s, sh or l2"

Yes i am sure: The comparison was done on two std rb20 motors with different bolt-ons, on the same dyno, on the same day. The graph shows that the GTRS lagged the TD06 all over the rev range.

I have even driven the two cars (at different times) and the difference is very noticeable.

TD06 17C 285kw

TD06S 20G 317kw

TD06SL2 20G 317kw

TD06SH 20G 330kw

rated at the compressor

Part number for the RB20DET R32/(and yes it will fit the R31) kit

- Intercooler piping is more suited to a silvertop (r32) engine however.

I have my sights set on a tdo6-20g 8cm LS2 if i have enough by xmas i think i will go rb25, manifold, ex gate and tdo6! Umm.... i am hoping mercury motorsport and just rewire existing loom which should give me more displacement and hence more torque down low. z32 should help with the tuning and the tdo6-20g 8cm might be small on the exhaust side however external gate might help! i welcome any input either encouragement or discouragement.

[RipNGrip]

can anyone suggest somewhere to source tdo6 and piping kit? in QLD/Brisbane

[Wheezy]

what sort of piping?

The trust kit for R32 TD06 20G L2 will incude, turbo, manifold, dump/front pipe, wastegate, intercooler piping (for stock plenums) oil lines, block off's for water lines etc etc etc.......

As far as purchase goes, there are quite a few retailers / workshops that can get the kit for you.

Im personally going to see how I go with the 8cm rear and if need be get a 10cm housing later on

[RipNGrip]

i guess i should just give gcg a call for a quote! umm 8cm on a rb25 should be awesome for response:)

[burnsie]

im running a gt3071r on my rb20 and i made 241.4rwkw i make full boost at 4200

T67 on RB25, full boost 1.2bar @ 3,300rpm ish

[RipNGrip]

I will have to sell my splitfires, and high flow turbo if i gut this rb25. hopefully they will be easy to sell

[RipNGrip]

gt3071r i thought that would be a little too big for a 20

Is it possible to fit the greddy turbo to a low mount cast iron hks manifold? Is there a special turbo elbow needed?

And what is the difference between the s and l2 version? It looks to me there is a model with internal wasteate available for s the s type, but not of the l2 type.

11500205 is the l2 for rb20det. Will it fit standard t3 manifold and standard type turbo elbows?

it would be a big pain in the ass to fit the td06 on the hks cast.

you have to be prepared any turbo on an rb20 is laggy.

td06 wont hit full boost till about 4500rpm and if u get the kit you better off buying the turbo only and getting a custom manifold made up.

i got 260rwkw with my td06 8cm rear housing.. but that was more than a 6k exercise when you include tuning and all supporting mods.

also budget for a rebuild in the future.

Got a dyno sheet of boost vs rpm and power?

[silver gts-t]

i do but not on PC only a hard copy.

that was on 19psi

[ivosp]

So the separately sold greddy td06 turbo sold to fit an r32 gtst will not fit stock manifold?

Its also hard to imagine a turbo like the hks gtrs reaching full boost much later then 4500rpm. On sr20 its very responsive. It's also fairly small (same turbine as gt2530).

[Roy]

With my car its hitting 18-19psi earlier then it really kicks you in the ass. So even though its got the boost on board, perhaps because of the dynamics of the engine (stroke and cams etc) it doesnt really boogie until 4,500rpm, at which point its making about 200rwkws from memory.

I personally think the 8 cm housing will kill a TD06 setup, will work much better with a 10cm housing. The 8cm housing will not like any boost on an RB25 and will probably trail off power a lot earlier in the rpm range.

But will be interesting to see.

As for the low mount HKS manifold, i think you are really better running something like a 3071 rather then try and adapt a TD06. Hp rating wise they are not overly different and would probably get a similar result.

[RipNGrip]

Well.. my opitions:

1. TD06...$6400 for the entire kit from CRD or 2479 for the turbo itself from ISC performance

2. HKS gtrs from slide

3. 2200 for engine, auto gearbox, loom and ecu, approx 1500 for installation excluding a rear diff change.... (different diff ratios)

This requires diff change, re-wire using existing remapped rb20 ecu and vtec controller for variable cam timing.

I am seriously considering 3. due to the modifying potential of the car however the wiring/tuning seems tricky. 20 ecu with 25 block and vct controller!

[Wheezy]

$6400 for the TD06 kit LOL...........

BTW: For RB25 Trust list the TD06SH-25G is a 10cm housing (so your spot on Roy)

[Wheezy]

On the topic of TD06 L2 and RB20, the total exhaust size with the trust 42mm external gate + trust front/dump (2.5" to 3" where it meets the cat)

So the total exhaust diameter is 105mm where the exhaust meets the gate/turbo.

Is it worth going a 3.5" front pipe back (with a setup like this f**k even pretending you have a cat if its street driven your pretty much f**ked in the ass anyway)?

Side pipe is fine for track but a nice cat back system with a good muffler would be ideal for a nice note on the street. I just wonder if 3" is enough?

3.5" is affordable and doable but theres no point spending money where there is minimal/nill gains.

What a farkin Rip!!!!

An RB26dett transplant would cost less than that..
