If you can hide things then great. I must be lucky as my engine bay has looked like those pics since 2003 and never booked. So if your car externally is nothing flashy and your exhaust is quiet then there is surely a good chance you will never be asked to pop the bonnet

Yeh, I am getting a HTA wheel on my TD06. Slightly bigger wheel but as you say the hub section is a lot narrower on the machined jobbie so more space for blades, hence the large increase in flow for little change in overall physical dimensions. Will know by end of Jan how it actually works in the field

Yeh the Greddy manifold is a 6 into 2, 2 into 1 type manifold with a nice collector. The 6boost manifold is pretty much equal length into a slightly longer collector. This is the greddy manifold... No need to see pics of the 6boost manifold, there are plenty around the net. The 6boost manifold many prove more durable, time will tell. But the above manifold is now being used on another setup by Kris with the L2 I pictured a few pages earlier. It did need a light repair on two occasions but nothing even my humble welding skills couldnt fix. Nothing wrong at all with the 6boost manifold. They appear to be well built and plenty of people ave got years of great service out of them. I suppose the point is if you have a china manifold that is serving you well, a HKS or Trust manifold working well...then I am not sure there is any point wearing the 2K cost of replacing it with a 6boost manifold as I doubt you will get any performance increase

This is the 10cm housing with the original Trust manifold I was running at the time. Yeh all Trust kit with off triangular flanges, uses to run the total Greddy kit, these days its a bastard kit with Turbosmart gate and 6boost manifold You are right, now that i am running a 6boost manifold the turbo sits a lot further forward and required moving the PS reservoir. Does give you a little more room for the dump pipe. For what its worth, the 6Boost manifold resulted in a loss of a smidgen of power and hurt response a little. This could be the result of there being about 18 months between dyno runs and the car had lost a bit of performance in that time. I also changed from the Greddy Type R wastegate to a Turbosmart gate. Cant see either really contributing to a loss in performance. Considering the new setup has nicer piping and improved exhaust system...i think its safe to say 6Boost is no better then a Greddy manifold. Possibly worse. If all the handfeeding over 6boost manifolds were true I should have picked up some response and perhaps made a tad of power, especially given the exhaust improvements. If I was starting from a clean sheet of paper I would go a Greddy manifold over 6boost now having tried both.

Racing? What style of racing? If its multi lap stuff then I would say go NA cubes anyday of the week. If its just fling aroudn track stuff then I say you are better sticking with what you have as the new setup is most likely going to cost an extra 10K on top of what you already have and the car would be probably quicker with that 10k spent on other things rather then engine

People car do things for all different costs, some cheaper some end up paying more. I dare say since these setups work so well you would be best to spend the few extra dollars and making the setup 100%. Using some high temp sheathing on lines, good quality bends and reducers/flanges studs etc so you dont blow out gaskets etc or warp with temp. A gate for $300? I paid about $500 for my Turbosmart. I paid more then $150 in just flanges, studs, gaskets and elbows + reducer. So not saying anyone was wrong but we all often pay different prices for things and I know i couldnt do my setup with external gate that cheaply

Fark it...i am selling all my mitsu fluff and going KKK K27s etc. Info on them is even more confusing

So Kando call the T67 turbine TD06SL2, when Greddy call it TD06L2. Greddy seem to drop the S from all the descriptions where as Kando use it. Here is the compressor cover of my old turbo

25G is the compressor. TD "whatever" refers to the turbine 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 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

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

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. 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.

Took today off work and doing a pre xmas clean. Forgot these are still here and would love them to go to a good home. Will take $1200 for the pistons

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 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

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

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. 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

Thanks Dori...lol I am going to back off because you seem to be cracking the sads with me wanting to be sure wires are not being crossed My last post on it...I have seen that first curve before and I thought it ws a TD06-25G?!?! I suspect its a 25G just looking at it. It is making less power at 4,500rpm then my RB20 with a 20G The second graph says GT-RS so ?!?!? Sure you are right but its hard for me to spot if I dont know the cars or the whole threads re the setup There is also another graph floating around on an RB25 from a few years ago showing different levels of boost and that was a TD06 with Garret wheels so ? It made 330+ but it had 3037/3040/God knows Garret wheels.. Anyway. Carry on. And Yavuz/Unigroup...I went to Uni with him...no doubt he knows way more then me and I trust him. I will be seeing him in the next few weeks so will raid his files and bust his balls for graphs before i change anything on my setup

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 These are the two dyno sheets I know of... http://www.skylinesaustralia.com/forums/index.php?app=core&module=attach&section=attach&attach_rel_module=post&attach_id=187000 And http://www.nissansilvia.com/forums/index.php?app=core&module=attach&section=attach&attach_rel_module=post&attach_id=184121 It says 305hp on the axis. If 305rwkws why does the axis say hp, surely it would read hp...but i dont know how the dynos work. If it is 305rwkws seems odd he is making 50rwkws more with 2psi boost. (18psi vs 16psi in the top end) Was also on the std RB25 injectors with increase rail pressure so ?!?!?! I am no expert but is it really reliable evidence? 124mph is impressive though I dont know the state of the tune at that stage?! What hp does that mph suggest?

People said that but the dyno sheet posted said 305hp on the axis. You might be right. It could have been 305rwkws with the wrong axis being shown. But seems high since most TD06 setups I have seen out of Dr Dift have been 250-265rwkws. Have you got the graph that you are referring to?

Sorry, reading back over my post. I was referring to all the people saying you "should" be able to get 300rwkws out of a 20G...Imy point was irrespective of motor, I am yet to see a credible/genuine dyno sheet of a 20G making 300rwks on PULP98. So if this thng gets up there then its a great result for the lil Kando, as the Trust and other knock off units traditionally have not been able to bag 300kws at the wheels. Be it because they are soft or just not enough people with the right setups using them??

So your mates GTR ran a single TD06-20G turbo? So many people confuse the TD06-25G with the TD06-20G. The TD06-25G is bigger then the T67-25G

Will echo some earlier comments on this thread. I am very keen to see any engine that produces over 300rwkws on PULP98. Be it an SR20, EVO or RB25/26 or RB25/30. I think you will find that they often make 270-280. Occassionally 280-290rwkws....but I have never seen 300rwkws out of one . So not sure why people say "should" regardign 20G compressors cracking 300. Anyway, if current discussions pan out than I am going to billet compressor wheel on my 20G. So will be interesting to see if it loses power, makes power, loses response/makes response Would you also be able to plot the boost curve? I am curious to see the difference between a 20 and 25. Especially since your VCT is off. Just means the extra compression and 500cc is working for you

SimonR32...care to step in and help out with the wheelspin in 3rd gear problem Great result. Hurry up and give the thing a belly full of boost as I am curious to see what the 20G compressor can flow on E70

My 2c... making it a track only for what reasons? To save money on rego, or because when you rip the ac out does it mean you would rather not drive it to events
