dangerous brain Posted August 5, 2007 Share Posted August 5, 2007 I am trying to identify my turbo to see if I can get replacement bearings for it. Failing that what the actual turbo is so I know which direction to go in with regards a replacement item. The numbers on the ident plate are this model T04 R P/N 17200 -154100 S/N BI - 7008J GTI P/N 465981 - 0008 Its got M24 and .70 A/R embossed on the compressor housing. I would like to find out if the r stands for it having ball bearings in t04r and what the exhaust A/R is. Also the size of the wheels would be usefull to know.

JamieP Posted August 5, 2007 Share Posted August 5, 2007 T04R is a HKS turbo. http://www.to4r.com/specs.php Link to comment Share on other sites More sharing options...
dangerous brain Posted August 5, 2007 Author Share Posted August 5, 2007 Yeah michel said it was in his original advert but there is nothing on the turbo to suggest its a hks unit at all. Even the ident plate is garrett. Lends a bit more weight to the theory that hks turbo's are just rebadged garretts lol Link to comment Share on other sites More sharing options...
JamieP Posted August 5, 2007 Share Posted August 5, 2007 Yea, this might be the garrett version. http://www.turboelements.com/index.php?act=viewProd&productId=7 Link to comment Share on other sites More sharing options...
dangerous brain Posted August 5, 2007 Author Share Posted August 5, 2007 Yeah see thats a 67 and mine is supposed to be a 61 That is exactly what my compression side looks like though even down to same embossed writing being totally identical. My turbine exit is also bolt pattern like this one but that page says its a t3 which i assume is the turbine inlet flange? So we seem to have found my compression side which looks like its a 67 not a 61?? So now to identify the side with no writing on it the exhaust side.

dangerous brain Posted August 11, 2007 Author Share Posted August 11, 2007 OK now I really think I have cocked up here. I bought a T67DBB turbo and it looks smaller than the one I have fitted to my car. After some more investigation I have discovered that my exhaust ar is 96 on my existing turbo and the one I just bought is only 68. Would I then be correct in thinking that I have just bought a turbo capable of less power than I had before? One question though, how comes the turbo I have only managed 455 bhp if its a t67 with 70 ar inlet and 96 ar exhaust? Link to comment Share on other sites More sharing options...
Robert Posted August 11, 2007 Share Posted August 11, 2007 jesus it had an exhaust AR of 96 on an auto? mine is 68. When i get back form the doctors i'll see if i can find what tubby u have mate. Link to comment Share on other sites More sharing options...
dangerous brain Posted August 11, 2007 Author Share Posted August 11, 2007 That would explain why it takes soooooo long to spool the bitch. Also why it doesn't seem to run out of puff lol. Its not even wound up to max power before it hits the rev limiter. Link to comment Share on other sites More sharing options...
Nic Posted August 11, 2007 Share Posted August 11, 2007 Lends a bit more weight to the theory that hks turbo's are just rebadged garretts lol It's not a theory, Garrett do make the HKS turbos, whether they are just rebadged or there are any spec difference is unknown.

AshBhp Posted August 11, 2007 Share Posted August 11, 2007 This is a HKS T04R Cutback and you should see the HKS logo as pic. Link to comment Share on other sites More sharing options...
dangerous brain Posted August 11, 2007 Author Share Posted August 11, 2007 Its got a HKS part number on the ident plate but I see nothing else that tells me its a HKS turbo. Link to comment Share on other sites More sharing options...
Alex Posted August 11, 2007 Share Posted August 11, 2007 The T67 from precision can't be compared side by side...with straight numbers. 1. The T04R you have is a divided housing this changes what the 0.96 means. In a divided housing you have extra metal in the way and that means that the A/R has to be larger to stay the same as the non divided T67. So the 0.68 A/R undivided is close to the 0.96a/r divided housing in actual flow terms. 2. Precision make them small frame on purpose, they keep the weight down. The actual wheels are then bits that push the air, you should take the cover off the housings and measure the wheels to really appreciate it, not the case.

dangerous brain Posted August 11, 2007 Author Share Posted August 11, 2007 Oh so the mystery just gets deeper then. OMG could it be any more complicated. Is BL precision then? Will the 0.68 A/R I am fitting actually spool better than the 0.96 A/R divided housing turbo I have? I am loath to open up a perfectly serviceable turbo to see what sizes the wheels actually are. The old one needs opening up to change the bearings if I can actually find replacement bearings for it. I don't see any HKS logo's on the old turbo housing.

Alex Posted August 11, 2007 Share Posted August 11, 2007 You only have to look at the data Ian C and SimonB have posted on here about the T67DBB to know what it can do. It's a FAR better turbo than the T04R. Link to comment Share on other sites More sharing options...

SimonB Posted August 11, 2007 Share Posted August 11, 2007 Yeah, you can't look just at the exhaust A/R and compare different turbos that way. A bigger A/R exhaust housing will spool slower and be less restrictive for the same turbo only. Different turbos have different turbine designs etc, so a .68A/R on one turbo may well make loads more power and spool slower than a 1.05 or something on another. Or vice versa.

dangerous brain Posted August 12, 2007 Author Share Posted August 12, 2007 So basically until I stick this new one on I am going to have no idea what the outcome will be? Hmm what a PITA lol. I'm sure once its on there all will be OK. Link to comment Share on other sites More sharing options...
