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)

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
