hi there

i'm looking into getting a TD06 20G 8cm for my cefiro - it has a 2.4 RB20 motor in it. currently have a hks 2530 on the car.

I'm after info with people running the TD06 on a rb25 and also rb20 to see if it is suited for my application... supporting mods are - gtr injectors / z32 afm / power fc / full zorst no mufflers/cat with screamer / fmic / fuel pump / pod / bov etc...

this turbo is also internal gate.

PLEASE HELP!

also if i get a good response i may have a hks 2530 for sale located in SA.

thanks

-Matt

run for your life.............

heheh just look for another turbo kit, had trouble with the internal gate, it just doesnt work, you will have to custom fit an external gate and blah blah, basically spend $$$$ to achieve anything. cost me 3k to get it working properly

get a 2535 or go garret unless u like the noisy wastegates

Edited by kidd
i've been speaking to a couple people and some have actually said that it may be more responsive than the 2530?

it feels more responsive than the 2530 on normal driving but it depends on what gear youre on, normally had to drop it into second when a 2530 fitted car would only need third to boost up eg when the traffic lights go amber at 60km/h and we cbf stopping :devil:

If you fit an oil cooler i doubt you'll have problems with the engine temperature (assuming your cooling system is in good nick atm).

I think a TD06 with small rear housing on the rb24 will be a bit of a ball tearer to be honest. Obviously less responsive than a 2530 size turbo but not too far behind and a fair bit more top end. I have seen internal gate td05's perform fine so i don't see how the internal gate 6 will have problems.

If you could get your hands on a used 2535 it could be ok . Or since you have the T3 flanged HKS exhaust housing you could buy a Garrett GT2871R in 48 compressor trim - minus the exhaust housing and fit it in your existing HKS exhaust housing . Assuming your 2530 is a Skyline specific one it has the TO4B compressor cover like Garretts GT2871R series uses so externally it would look the same and use the same water/oil/exhaust plumbing and waste gate actuator . The only difference may be the comp cover inlet boss being 3" or 76mm where the HKS 2530 probably had this bit machined off and an adapter bolted on . You could either get this boss turned down in a lathe or use some kind of step down in the inlet plumbing depending on what you car has .

Just in case you didn't know the 2530 and 2535 and all GT2871R series plus a few others use the same identical turbine and bearing housing so the HKS exhaust housing goes bolt . Done the above mentioned way you wind up with virtually a HKS GT-RS but in 48 comp trim instead of 52 trim (better when boost threshold is an issue eg Cu in starved RB20) and without HKS's custom port shrouded comp cover . The 48 trim compressor is less likely to surge than the 52 trim GT-RS but you could get the 2871R's comp cover drilled and slotted so the port shrouding worked TO4Z style if required .

So if you play your cards right this could be a very cost effective upgrade with what is really a brand newin .

Cheers A .

They arent a bad turbo, though as someone else suggested the internal wastegate versions do not seem to enjoy the success of the external gate types. I think thats mostly due to the exhaust housing design and subsequent dump pipe the internal gate version has to run.

Here is an external gate version on a completely std RB20.

well i've made 236 previously with stock rb20 / fmic / zorst / 1.3 bar / hks fcd / stock ecu and injectors...

not going to kill myself if i dont get 240 hehe... just a goal. be happier with insane midrange/lower than peak power atm.

cheers roy and like you said can always change it down the track if i want to :)

    • Apologies for the long post, but needed somewhere to lay out the entire timeline of events and actions taken:   I've got an 89 GTR with a R34 RB in it. It's been running great all year, driven probably 500KM in the last month. It's not my daily driver, just a weekend fun car.    Build info: R34 RB26 - HKS 2.7 stroker kit, HKS adjustable cam gears, HKS turbo upgrades, Trust intercooler, R34 factory DENSO 440cc injectors, JUN chipped/tuned R32 ECU. All of this work was performed in Japan back in 2019.    Thursday 10/2/25 - It's a nice day and decided I'll drive it to work, I start it up in the garage and I notice it took a few extra cranks and sounded a bit funny. I figure maybe it was just because it was a pretty chilly morning. I pull it out into the driveway to warm up a bit before leaving. As I leave the driveway, it feels very off and sounds like a misfire. I pull it back in the garage to deal with after work and take the daily to work. I was able to diagnose it as a cylinder 5 misfire with the old spark plug test (unplugging each plug until a sound change with the engine running). I take off the whole ignition system, ignitor, plugs, spark. *Important note, it is still on the R32 ignition system with the separate ignitor system. I test each system with a multi-meter and nothing presents as a smoking gun. I put it all back together and it starts up no issue. I go ahead and order the PRP R35 ignition conversion kit. It should arrive today (10/13/25)   Friday 10/3/25 - Another nice day, car starts up great and drives great all day. Very pleased that everything seems to be OK   Sunday 10/5/25 - Decided I'll take it to play some golf, load up and drive to the course about 25 minutes away. Drives wonderful the whole way there, I pull in the parking lot and the engine completely comes to a stop. I do not recall if it sputtered at all, but just remember all of the sudden the engine was off. I roll it into a parking spot, try to crank it back on and nothing.  It'll crank and crank and not even try to start. End up getting it towed back to my house and push it up into the garage.    Items I have checked: Fuel in the tank Fuel Pump relay Fuel pump fuse  Spark Plugs & gap Coil packs Ignitor    I know the cylinders are getting fuel as the plugs smell like fuel after a start attempt. I tried spraying starter fluid into the manifold and cranking and not even a sputter.    I decided to do the live CAS test (removing the the CAS, ignition on and spinning the CAS stalk to see if the injectors pulse and spark is active). All of the injectors were pulsing and I have spark at the plug. The half-moon end of the CAS did seem very loose, I'm not sure how much play is supposed to be there, but it was more than I expected. There was no in/out play of the shaft, just the tip end that is pinned on had quite a bit of play.    CAS Play video   When I put the CAS back in, I stupidly did not re-time the engine. I know I need to do that tonight, however, I do not think it will start given it seemingly was not the issue. My plan is to do the PRP R35 coil kit and retime the engine at the same time.    I plan on ordering the Haltech Nexus Plug-in ECU once they are available again, but ideally would like to get this sorted before firing the parts cannon at it and potentially adding more variables.    Anything glaring that I am missing here, I'm a bit at a loss?          
    • Get it on a dyno. Get something logging Consult. Run it up and find out what is causing it.
    • Looking for a plenum for rb25 de+t neo  Not looking to push much power maybe 300kw at the wheels, is there much difference in flow for Freddy “Greddy style” compared to original Greddy or options like Proflow or Otaku garage?    I won’t be porting the de Neo head for now as I think it’ll be fine 280-300rwkw but appreciate the help and any experiences anyone has between them and any advice. Thanks  Looking at this plenum for now below 
    • engine wise almost no mods: stock ecu Greddy front mount intercooler Greddy forward facing intake w R33 TB stock fuel system, stock injectors, rail etc. Kakimoto racing hyper 3 inch exhaust system Apexi intake filter New NGK –R BCPRES (.8 gap) plugs  
    • Nice one @Pac - looks like a fair few 1600's there!
