back to topic..

according to the title, I will say TD06-2og will be easy to drive around, and comes with some very good power, and if you can invest some $$ on cam gears / cams then it will be perfect..and this is back up by riding experience of Buster's car. thanks.

I will ask buster to answer this questionin in detail..

But I will say what I saw..

Td06-20g 10cm sqr, trust manifold, front pipe,3 " exhaust system, external wastegate, Trust cooler, EVC, chipped R33 ECU..

from what can see at passenger side..spool around 3100...hard at 4000 (up) till red line...lag was there, but not what I expect..power come smoothly..

He sold the car....and the car now is in autostyle sydney..but both of us will have something similar come up soon..will keep you post.

mmm... on the other turbo's thing...

(don't shoot me i'm no expert)

I think i still have the stock t04E that came on GTS-R's.

Now my car has an RB25 though and it hits full bosst around 4300 and makes boost from around 3500 or something near that.

It produces 190rwkw @6600 on 9.5psi

at 4500 it has 120rwkw and 5500 it has around 160rwkw.

To drive it's nice, and between gears i don't drop 1,500 rpm (maybe i have modded box, no idea though), so i can stay on full boost in every gear.

I know that a t04 is like super old technology and stuff but you can mix/match the exhaust and front housings/wheels i think ??

And from what i've heard they aren't all that expensive. Like approx $1500-$2000 ?

just a thought that's open to discussion as i wouldn't mind learning some stuff :D

Usually on the compressor or front housing, and the exhaust or turbine housing.

Turbine housing is pretty important to determining when a turbo will come on boost, the smaller the housing, the sooner the boost comes on - the trade off being you wont have as much top end. The sort of power you are making is easily acheivable with a stock turbo, but they tend to come on boost just over 2K with a good exhaust setup.

If I had to guess, I would say that your exhaust AR ratio is a little on the large side.

EDIT: also the T04E isnt a small turbo for a 2.5

NFI!

i've got this extractor cover/shield thing. I'll get it off in the next day or two and have a look.

I do know though that the mouth (where it sucks air in) is reasonably big.

mmm, i've seen cars achieve what i am with the stock turbo, but they are all running more than 9psi of boost ?!?

Yes, true, but think about this: my car runs 12.5psi has a stock turbo and makes boost from 2000rpm full boost by 2500 and 203 rwkw peak,

You have 120rwkw at 4500,

I make 120rwkw at about 3300rpm, by 4500 I am making 165

rwkw. By the time your engine is making 160kw, mine has made 190.

It takes you nearly 1000 rpm to make your 9.5psi, I can get 12psi in about half that and it starts 1500 rpm earlier.

Which setup, if both were fitted to the same car do you think would make a quicker car?

Now, if you could make 12.5psi by 3000rpm...

yep Phil you hit the nail on the head all I can see you missed is the 550 inj, Bosch fuel pump and Z32 afm

It did start to spool in the low 3000rpm's and had full 1.1 bar by 4000rpm the boost did come on pretty harshly hahaha all in all I think the set up is great when you look at the cost of one of these turbo's and how cheap they are to have rebuilt

Hi Guys, I posted this before....

Graph peaks at around 308 rwkw at 196 kph which would be 7,250 rpm allowing for 27 kph per thousand RPM. That means at 108 kph (around 4,000 rpm) it has 93 rwkw

So if you changed gear at 7,000 rpm in first the engine would have 300 rwkw and would drop to 4,000 rpm in second where it had 93 rwkw. It would then struggle to accelerate the car until it got to around 5,000 rpm when the power jumps to 180 rwkw. This would indicate not very much boost under 5,000 rpm.

Simple table follows; as shown on the TD06 dyno graph on page 1

At 7,000 rpm it has 300 rwkw

At 6,000 rpm it has 250 rwkw

At 5,000 rpm it has 195 rwkw

At 4,000 rpm it has 93 rwkw

That's an average of 210 rwkw.

This would make, firstly a fairly slow accelerating car through the gears as it has a relatively low average amount of power (210 rwkw) compared to its maximum. Secondly this would make it very difficult to drive as it would be constantly moving from over 300 rwkw to under 200 rwkw with only a 1,500 rpm drop in revs.

I would say that the turbo is too big and the car would be faster with a smaller turbo, say one with a 260 rwkw maximum. Power table like this;

At 7,000 rpm it has 260 rwkw

At 6,000 rpm it has 240 rwkw

At 5,000 rpm it has 200 rwkw

At 4,000 rpm it has 170 rwkw

That's an average of 220 rwkw.

Higher average therefore faster accelerating and it would only drop from 260 rwkw to around 220 rwkw in the same 1,500 rpm bracket. Result = much easier to drive.

Hope that made sense.

*Now, read it, and stop talking about TD06's unless you all own a Mitsubishi Canter*

Sorry, that was way too harsh....had the 5am blues....rally didn't mean to say that like that...I meant to say

"now, stop talking about it

unless you own a Mitsubishi canter....."

In that i beleieve everything had been talked about here, and all the numbers have been shown... not that they are crap turbos so don't talk about them...i did not mean that

I honestly have no doubts that the TD06 could be a very effective turbo. I personally believe that running one on a 2.5 litre engine is not the best option. On a 3litre + engine i believe that could be very good, and would spool up 25% earlier. I have seen one on a diesel Hilux that was VERY interesting

I'm sorry if that sounded like me telling you you picked the wrong turbo, or that you are all worong, i really didn't mean that. I have personally never driven a car with a TD06..or for that matter any Trust turbos. I have driven a toyota hilux with one....that was scary. But the numbers coming out of the dyno graphs all seem to say the same thing, and spool up, at the bet off an RB25 was 4,000 rpm.... And i believe that does not add up to a very streetable turbo. But i could be wrong

Hi, SydneyKid..thanks for the replied (not the ....quote.....part), and be honestly I do learn from it..but Were the fact and theory are brothers? Were they sometime back up each other and sometime don't due to some reason? I don't drive a canter, just what I saw is a bit different then theory..please don't take it as offense (I know you don't...hahaha..thanks.)

If there is any chance, we do love to offer you a drive..and maybe you can help us to find out why?..thaks

If I was to consider either a rework of my turbo or a garett combo what in your experience gives the best performance. Mick from Subzero now works were I take my car to so he says an exhaust manifold helps alot plus you know his plenums. For interest to back this up he is doing a standard turbo with exhaust manifold. Its on a friends car so should be interesting.

I would like to see 250rwkw for wank factor plus I believe this is a reasonable level to get to before needing injectors and maybe other internal mods. I have all else required.

So I could look at a Garett 3040 or a 3035. I would prefer to keep my origonal turbo however could have that reworked. End of the day though these all seem to pan out to the same cost.

Thanks

Hi Grepin

250rwkw is not a whole lot really. this is easily achievable with the hi flow, for a fraction of the cost... it simply bolts straight back onto the original exhaust manifold... very simple. you do not need such a large turbo for these figures. It is far simple and far more cost effective to simply get a Hi Flow job done on the existing turbo. Save the cash you save from not buying a new turbo and use it elsewhere on the car.

Son of Sydneykid

hey rob

it isn't the most effecient manifold, but for the 250rwkw, its sufficient... It is not an equal lenth manifold.... but its not worth spending the cash on another unless you are going way further than 250rwkw...In my opinion...but i will ask the old man

Son of Sydneykid

I guess I should have stated that to get 250rwkw that the standard manifold will do. However would a nicely designed manifold make it work all the better. I guess the proof will be in the car that is keeping the stock turbo however getting a manifold. Certainly a different way of going about things. Consider if I havent got it wrong it may be possible to get more top end out of a set up manifold. Like how it can be said that a larger turbo can be brought on boost earlier by a specifically designed manifold.

Sydneykid, so you havent had much experience with Garett turbos like 3040 etc. Cost wise considering Sacrifice $500 worth of turbo for a $2400 (GCG price) rebuild is more expensive than buying a Garett turbo (from $2300). Given the fact that I want to keep all my stock parts I would prefer to keep my turbo. The only reason to rebuild it is if it would be far superior than a garett turbo.

Cheers.

I hope I finally get it right when I do comit to something. Its even more frustrating when you have the money but no idea what to do.

    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
