the second graph (red line is the GTRS run, to show that it outperformed the GTRS)

this sheet was posted by trent himself, feel free to pm him for verification cause it looks like you still don't believe it can be done.

trent has already confirmed numerous SRs & RB25s he has tuned on 98 and pulled over 300rwkw mark :thumbsup:

nuff said, so stop arguing that it's impossible.

it looks like you're having issues getting to the 300rwkw barrier so i guess i can see your reasons for not believing the results,

have you spoken to your tuner and got his opinion on it?

Interesting thread this. I am planning:

Rebuilt Trust TD06 20G

Top Mount

50 mm wastegate

Plazmaman plenum

de cat

HKS silent hi-power

Trust FMIC

Unopened motor RB25, stock cams etc

I got this turbo because a) it was available with the top mount manifold 2nd hand b) should be fairly responsive even if it is old tech.

I am looking at the compressor maps and have in my mind it will be comfortable to hold 18 psi to redline, maybe 20 psi. 25G compressor would for sure make more top end and be more efficient at high rpm on the 2.5 L, but I want response and I would take punchy 250 rwkw, would be happy with that. At 20 psi at redline I make it about 650 cfm which close to the edge of the envelope for efficiency and compressor rpm.

I think 300 rwkw would be a ludicrous amount to get out of this set up on 99 RON (what I use) but we will see what it does in a few months.

I have seen similar posts and people reference it. I have never seen a dyno sheet. I have seen some T67 sheets. Not 20G = 300rwkws posts. I want it to be right, just want to be sure its right

Just not sure if its reliable info. Dont get me wrong, I want it to be. If there is another 30rwks in my setup I would like to know

Aren't you running a RB20?? Maybe this is why you can not make 300rwkw where as the RB25 with VCT can make 300rwkw?

Thanks for clarifying. Interesting that the 20G didn't outshine the GT-RS more. Interesting it was that close. So thanks...I can bank that as a credible result. :thumbsup:

Regarding me, I have not been trying to make 300rwkws. I have been trying to make another 20rwkws between 4,000-4,500rpm. It has gone backwards with the plazmaman plenum and 6boost...so my setup is far worse then what you are all doing with the your setups and never going to give the numbers the turbo is capable of.

I base most my thinking on two cars, one was a friends who tried pretty damn hard to bag 300rwkws...going with Greddy plenum, baby 256cams, RB25 with 8cm and 10cm housings. They just seemed to run out of compressor flow. But perhaps that dyno was just busting their chops by reading 15rwks lower which seems a possibility given differenes in dynos

FYI, the TD06H-20G is different to the TD06SL2-20G.

it runs a larger rear wheel and will pull more power then the SL2 but compromise will be response.

its just a number, remember that :)

its all about how it feels in the driver seat.

i know how you feel going FFP, i wished i never went that path as well and would prefer stock over this anyday! only good thing about it is it makes the engine bay neater and spark plug change easier.

Aren't you running a RB20?? Maybe this is why you can not make 300rwkw where as the RB25 with VCT can make 300rwkw?

LOL, the whole story is I have two RB26 bottom ends, heads, Tomei 2.4L pistons and solid head gear....a Trust T67-25G 10cm and a TD06SH-25G 10cm all sitting in a factory with an RB25 and an R34 GTR Getrag gearbox. One day the lil 20 will die and with E85, and cheap internals etc would be pretty silly to not try and update the power my car has.

If my trusty old 20G just needs the 10cm housing off my T67 and slapped on a 2.6L will give me a punchy 300rwks then fark it...i will flog off the new turbos and they will bag me more money to build up the engine then flogging my 7yr old 50,000kms TD06-20G :) If I can just put a set of RB24 pistons and the spare crank in the RB20 block then I can sell the complete 26 bottom ends. It all influences my thinking/budget

So the above is the reason I am hanging around and asking questions. I will stick with the lil 20 as long as possible, but given the grunt people have at track days these days...something that pulls in 5th gear would be nice :whistling:

LOL, you say its just a number...but it is amazing how happy or pissed off the number can make you. Just like times HUGE difference between 13.05 and 12.95 :)

FYI, the TD06H-20G is different to the TD06SL2-20G.

it runs a larger rear wheel and will pull more power then the SL2 but compromise will be response.

I get confused, and sometimes confuse others with the hot side talk, is it an L, L2, SH, H, S etc etc?

If you read my turbo tag it says TD06-20G. What that makes it I dont know. Tim, who has a car the same colour, same tuner, but a complete L2 Setup....when you read his turbo tag it say L2 made within 1rwkws on our tuners dyno. Mine was more responsive but that could have been down to engine health, the temperature on the day. The take away is in our case the L2 hit a wall at 19psi just like the plain TD06 with regards to making more power with boost and was no more responsive or powerful.

I had an L2, and was so unconvinced by any real tangible difference I sold it to Kris who is now running it with my old manifold. If back to back testing with the same tuner and same model engine and same dyno showed more potential I sure as shit would have sold Kris my current turbo and kept the L2.

So then you have the the TD06-25G. I think that technically the TD06-25G is a TD06SH-25G. Whatever it really is, the thing to remember is that the rear housings cant be swapped between them

Here is the L2 I sold to Kris next to my TD06-25G

In this case the wheel is going to make a difference to performance. If you are talking the difference between the wheels that can have their housings swapped, 11 blade, 12 blade etc? I think its a bees dick between them. The wheel off the bigger TD06-25G is going to flow a lot different. Thats why I think Trust list the T67-25G differently to the TD06-25G as the turbine is significantly different that given the same compressor will deliver different power and response.

I am pretty sure you cannot get a 20G with the same turbine as the TD06-25G

Those that have been around for a while there is BU5TERs old setup. This was with baby cams, TD06-25G, greddy plenum and jap re-written ECU. Its the setup that a few friends have copied.

med_gallery_462_50_31600.jpg

With a Power FC and another dyno it was making 345rwkws...then he popped it leaning on it with funny fuel and went to a crazt RB30 setup with T51.

omg, did you even read this thread luvpsi?

the td06-25g is basically what this thread started from, the t67-25g!

The T67 has a TD06-20G turbine. The TD06-25G has a much bigger turbine as per my post above. The T67 makes less power but is more responsive then the TD06-25G (on paper)

Would be interesting to see someone back to back them today. Back in 2006ish the talk was the TD06-25G was the better bet on a built motor where you wanted to run 22-24psi . Who knows if that holds true today

But the hot side of the TD06-25G is a lot more different to the hot side of the T67-25G compared to what people say about the L2 TD06-20G and the non L2 TD0620G

Thats why I think Trust list the T67-25G differently to the TD06-25G as the turbine is significantly different that given the same compressor will deliver different power and response.

seems as though it all goes in one ear and out the other...:no:

Bit tough fellers, Roy said above that they are two different turbos.

25G is the compressor. TD "whatever" refers to the turbine >_<:thumbsup:

My TD06-20G is coming off in Jan so will take photos of it next to the T67-25G and the TD06-25G i have. You will see the turbine of the T67-25G is very similar to my TD06-20G and way smaller then the TD06-25G

I dont have any pics that show the turbines, but this is them

T67-25G

med_gallery_462_50_33480.jpg

And the tag on my 25G reads "TD06H-25G" Pics in Post 1488 are of this turbine - right hand side

So i am guessing my current turbo is a TD06S turbine, but I have never measured it up. It came off a twin GTR setup. I know it takes the same exhaust housing as a T67, but not my TD06H-25G

t67-25g

very very minor differenes - .1mm difference in the turbine wheel and .3mm in comp wheel.

best to just get the t67-25g which is already tried and proven by a few in this thread.

as you can see on the chart above from ARTZ, the t67-25g has the exact same power output as the TD06H-25g
