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 :)

    • My take on gg2 48mm, 54mm, 58mm, and 62mm compressor map for same size compressor vs gg1 : All gg2 only outflow gg1 above 20 psi. As all g gen 2 surge line at lower left of comp map move to the right, all gg2 sacrifice spool vs same size gg1, surge line move to the right worst for 54mm gg2. So for same size compressor if you want best response, use gg1, if you want max hp at >20psi use gg2 but you will be laggier vs same size gg1. Max compressor efficiency drops to max 75% on all gg2 vs max 76%-80% of same size gg1. Iirc lower efficiency means hotter iat less dense air so lower hp at same operating point of comp map. Also curious why gg2 is mapped to lower max rpm vs same size gg1 (only 48mm size both gg1 gg2 mapped to same rpm) : 54mm gg1 165,000 rpm  vs  gg2 160,000 rpm. 58mm gg1 150,000 rpm vs gg2 140,000rpm. 62mm gg1 145,000 rpm vs gg2 140,000 rpm. If gg2 can safely spin to gg1 rpm then they can flow a bit more than as mapped. Good thing that all gg 2 interchange compressor and turbine housings with same size gg 1. So gg1 owners can buy gg2 chra only if planning to boost >20psi.
    • My stuff is all with Shannon's, granted, I don't really have imports I'm driving on the road, however, I've had multiple cars at the same time with them. Presently we have the Landcruiser on laid up cover, Sarah's Kluger on full cover, and the house insured. About 18 months ago Sarah wrote her Subaru Liberty GTB off, insured with Shannon's, and the payout, and buy back of the wreck was super quick. In 2020 we had the VF Commodore totalled in a major hailstorm. Storm was on the Saturday, I called on the Sunday and lodged it, vehicle was towed on Tuesday night, assessment team called on Wednesday to say it was a total loss and get payout details, money was in the bank on Thursday morning. Have had a few other claims both at fault, and not at fault, over the years, and never had an issue with them.   Funnily enough, they're also the cheapest insurer I find for things like Sarah's Kluger.   I will say I'm less impressed dealing with them lately around "the experience", as a lot of their staff that you deal with aren't car enthusiasts. Shannon's has a much more main stream feel ever since they decided to become "big corporate", laid a heap of staff off, and then hired a bunch of non enthusiasts. At the same time they've been making a push to be less "call us and we'll personally have someone who cares help" to "hey, this computer can do stuff for you" and are trying to get more square pegs to fit round holes. (That's just the vibe I get from them). Again, have had no issues with claims with them, but get a bit of a "less personal" feel from them.
    • A thing I wasn’t happy with with enthusiast was during the initial phone call they told me they’d insure it for 130k but needed photos.   I then sent them photos and they told me $80k as there were other cars either similar modifications available for around that price, I told them to send me the links to said cars so that I can buy them. i then sent the modification list with prices of the parts (no labor) and the price then came to 115k, which is still shy of the 130 that was agreed in the initial phone call 
    • Ask me a bit later this week before payday
    • I agree that delayed payment probably isn't the most suitable solution. It seems a solid complete transaction would be best. As I wouldn't be using this sale as a line of credit that would typically earn interest, we can probably arrange a much cleaner single transaction deal. I can do $92.52 today. Would you prefer EFT, or Cash on Pickup?  😛
