So a 3076R 0.63 which is smaller is EVERY way can be ok on a 30DET but this is too small...

i think you are missing the point here! you are saying that the turbo is ramping too early and has no legs up top? im saying too small as in maybe they sent you thr wrong turbo!

a t67 should but upwards of 300+wkw with no issues what so ever!

Hey guys,

In a bit of a pickle, I've got a TD06-20G 12cm on my RB25 and it's a lot laggier than I expected. Although it wasn't tuned on what boost I wanted (20psi), it's only running 13.

I'm guessing that the turbo isn't in it's sweet spot and is taking it's time doing anything. I've been searching for weeks about info on the 12cm but I can't find shit (yes I have searched this thread many times!).

Has anyone run or tuned such a beast on a 25?

It made around 235kw which is decent power for the boost run I guess but yeah wasn't expecting it to have full boost around 5500rpm, any ideas?

12cm rear will add to the lag

chuck a few more pounds into it and see how it perfoms but will def be sluggish under 4k

It's out of the boat yard finally :P

Will more boost change the power curve, i.e turbo start working it's magic earlier? I was looking at two graphs somewhere in this monstrous thread and it seemed this way (same car, two sheets at diff boost levels). But yeah I'm noob with this stuff.

Hmm I wonder if that 10cm would fit.

Is it a TD06S or TD06SL2? That will change what housing you need to buy.

Either way a 20G on a RB25 with whatever rear housing should be running a 10cm.

Your 12cm is just making it doughier without benefit. Easily fixed though as mentioned.

Also, is it a T3 or genuine trust 3 bolt?

It's a TD06S and it is a T3.

Spewing eh! Ahwell I got it cheap ($600 via Ebay special). Atleast it's fixable, just a pain in the arse lol.

I wonder if Raz' 10cm rear would fit my turbo, hmmmm.

Cheers for all the help guys :)

Unfortunately it wont.

The SL2 is 61mm but the S is 65mm. Kando doesnt even sell housings for the S no more.. You are better off selling it as is to someone with a bigger motor and swapping it out for a Kando item. Im guessing its also internal gate with that abortion of a 3 bolt discharge?

Unrucky.

Alternatively, you can send it to Hypergear who will be able to machine up one of his 5 bolt Type B rear housings to make it dance.

i saw trent talking about running a tdo6 (of some description) with 12cm combo on a neo...my guess is it will come on a little later but make hard power all the way to 8000rp+ and then some ...5500 does seem a little ridiculous though..vct working?

So pump it full of boost and rev it hard and hopefully you should see some good results..good for hard sliding anyway...if its a streeter/racer drop it back to 10cm...

Here you go Jez

As far as I know, it's a untouched RB25. Full boost is actually 5750rpm lol, as you can see it's a slug to drive off boost too.

I've spoken to Eiji and they do make a 10cm rear for my turbo so I'll probably get that sometime next year.

Really wasn't expecting it to be THIS laggy, live and learn I suppose.

    • That's awesome. Fully serviced/full log book history for one of those cars is super rare from what I know. With JDM's like Skyline's, Supras, are quite hard to find one with full log book history. S15's seem to be somewhat of an exception, at least the spec s australian delivered models.
    • Hey all, It's been a bit since I have been able to update.  I pulled the fuel pump, first off it was a "universal" pump and the strainer was very clogged, and it was folded over on itself.  I replaced the fuel pump and all is well....  No more stalling.
    • That's convinced me I'll bump up the G30-660 to 770   Any idea if the difference in boost pressure? Cheers

    • Hey guys so turns out this project is going to be much bigger than I thought haha but I've done some my homework and have done a few panels on my car, but one part I can just not visualise is this. If I do a spot repair and I put filler in a dent for example and sand outside of the repair with 320 grit lets say so the primer can stick as I will only put primer on that repair and the surrounding area and then repaint the whole panel. Don't I need to make sure that I don't put primer on the old clear coat? I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down, it's still shiny. I thought putting paint on clearcoat or primer on clearcoat is a bad idea because it won't stick. So in this scenario it's a bit different to mine but imagine someone doing a spot repair and only painting that small section of repair but the new paint is landing on the old clearcoat. What am I missing?
