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

Lay off guys. I think there are about 6 Skylines in the country that dont have bent chassis rails. I know mine are banged up from hoists and trolley jacks. I have also rounded shit loads of bolts. And dropped a car off jack stands/trolley jack with only 3 wheels on the car (iw was very , very late and we were all very tired) He isnt taking on any major works, jacking alloy nuts on a strut bar isnt going to damage the chassis...it may bend/shear a bolt as was the case... Start slow and research before you spin spanners and GO FOR IT. But as badharidave said, make sure you are jacking the car correctly and using the stands correctly. My old cheap trolley jack used to drop pretty quick and had to always put wheels under the car at a minimum if I had to get under the car at the track and didnt have stands. Wheels damage underside of car so using the stands of the front of the rear cradle, front tow hooks, castor rods, gearbox cross member or engine cross member is the go. It depends what I am working on as to which point i use for stands

Still for sale.

I cam barely get in/out of bed because the boxes are so big so need them gone so I can afford another set of seats

What areas of the Falcon chew the money? Curious, as I woudl have thought they would be reasonably economical to run given their turn of speed

Not sure what to make of Sutil. Hulk on paper will be interesting up against Di Resta. Would think that Mercedes will be looking at their respective performances and how Schuey is going

I have only seen a back to back of a Trust TD06SH-25G vs HKS 3040 on RB25s, both with std bottom ends, Greddy inlets, baby 256 cams and Pfc. Very similar setup. The 25G was more responsive and made more power on the same dyno, Would be very curious to see the results of a good T67-25G vs HKS 3037/3076 comparison. I am not sure the 3076 would be a clear winner for out right performance

Any pics or info on how the oil pump gears went in? Pressure differences ?

Just man up and run so much boost that you dont even need a wastegate!

I was only debating this week that I thought Dan would be at STR and any Red Bull money that was going to be used to fund seats at other teams would be used to find seat for the establised STR pilots in the hope that it will turn into a paid contract. So i am tipping Alguersuari at Caterham and Buemi out in the cold with a 3rd seat at RBR

LOL, Ive have had my TD06-20G for 7 years. They were rocking horse shit in Aus when i put it on because of their "Truck turbo" reputation vs the swanky BB Garrets/HKS. They do seem to be everywhere in plague proportions these days and that because the results obviously speak for themselves Still...be a man and go Trust rather then Kando edit...if my car as stock I would go Kando...they are gaining a great reputation in their own right

Already looks great. What wheels are you throwing at it?

Do Spa and camp! Beauty of Europe. Everything is within driving distance

Personally I am yet to see any dyno sheet of a TD06-20G (be is TD06S or TD06L2) make +300rwkws on 98 pump fuel. I would love to see some, especially SR20 plots as those that I have found and compared to my RB20 plot have been found to be wanting.... And has anyone ran one of those internal gate housings? They look horrible for effeciency?

Cant believe you are starting down this road without supervision from an engineer
