Did Kier Wilson run a similar setup on his OSGIKEN RB30? Might of been TD06 x 2 but that was good for a 9 sec pass on street radials.

I like the mitsu turbos personally and at 18psi you certainly have room for more boost if you want. You'd probably be looking at 500rwhp+ easily.

The lag on a standard rb26 will only last as long as they take to blow it up

Dude, grow up. That is a stupid thing to say.

There have been plenty of stock engine 26 to reliably push over 400rwkw when tuned correctly. I raced a 15yo stock bottom end 26 for 2 drag seasons with nearly 400rwkw's... mid 10's. Willall's put a tdo6 kit on a stock re-build bottom end GTR with well over 400rwkw... that was 4 or 5 years ago at least.......

A correcly tuned td05 kit would actually be easier on a stock engine, as compared to smaller turbos for the same power level.

I'd suggest a set of drop in 260 deg cams to compliment them.

Obviously you will need a fuel system and other supporting mods to get the best out of them.

hey guys

im thinking of going twin high mount td05 16g, just wondering what power they are good for on 17-18psi

also how laggy they would be on a standard rb26?

cheers

Considering in your other thread just a few days ago you said...

ive got hks gtss turbos at the moment ... after a single ... set up ... i want it to be responsive im only after 400-450rwhp on 17 18 psi

The answer is VERY laggy compared to what you have on there now (if it was correctly setup).

So... what is it?

400-440rwhp or 540rwhp?

Then you also said...

the reason i want to go single is because its easier to work on as the engine is in a s15 and there isnt much room,

You think two high mounts + gates + plumbing/piping is all going to be easier to work on than int gated factory mounted turbos?

How often do you think you are going to "work" on them? You shouldn't be pulling the turbos off once bolted on...

:)

1. Your current setup (GT-SS's) is poorly setup, you have improvements to make there...

2. You've set your requirements and in less than 5 days have turned them upside down...

I'm sensing a severe case of major indicision :rofl: - you really need to sit down and think about exactly what you want.

Changing your mind/requirements/goals will lead generally to a hasty decision.

If the guy wants top mounts... he wants top mounts. GTSS's arn't the b all and end all in rb26 turbo's....

If he want's top mounts, td05's are going to be about the smallest top kit he's going to find easily.

Response is relative...

This thread isn't about singles, 540bhp or how hard turbo's are to work on... reguardless of what else has been posted elsewhere.

It's about TD05's...

We've all thrown around different ideas, asking peoples opinions on different setups... why not? This site's purpose is to gain from others experience and share information.

Back to the OP.

A td05 kit would be unique, powerfull and look good in a S15. Yes the td05's will take more rpm to come into positive boost than gt-ss low mounts... They will also flow -ALOT- more air/hp with much less exhaust back pressure, less shaft rpm and cooler intake charge (all will atribute to more power and easier on your engine).

If you have a built bottom end- even if you dont, 20+ psi of boost will nab you well over 400rwkw... even with a standard head. I made 398rwkw with smaller turbos on 98 pump fuel with a standard 15yo rb26.

Trust turbos produce some good numbers...

Ok then so why don't you put it in plain english then - you highlighted the "pros" nicely, what about the cons?

CON - They will be extremely laggy for the output.

Nice and clear, simple. Addresses on of the questions clearly, rather than sliding it in among "pros".

I'm yet to see a Trust Twin setup be as responsive as a Garrett/HKS setup.

Numbers aren't everything, nor are dyno sheets.

Happy to be proven wrong if you actually have proof?

Dude... I'm not getting into one of your typical keyboard warrior arguments. Especially as your a mod (you will just delete my post... yes you do.)

I did write that they take longer to come onto boost than a pair of gtss's... BUT WE'RE NOT COMPARING TURBOS! AND this is not going to be ANOTHER Trust v's HKS turbo comparison thread. You can't... they are completly different!!!!!!!!!!! I CAN prove that a td05 kit WILL make more power and spool slower than gtsss. I'm not and cant say they will spool faster or are comparitive- where did I post that?

Horese for courses...

They will however, produce the same power as a pair of gtss's at less boost, less exhaust manifold pressure and timing... thus easier on your engine.

Personal note- Nismoid, I do find you very abrasive at times around the forum.

I recall seeing in a Jap magazine an article on a car running the twin TD05-18Gs, the ones with the bigger bellmouth inlets and the thing appeared to be an animal. They looked to be equiv/better then 2530s because the manifolding and twin gates. They are similar sort of turbos to the EVO crowd so dont really understand why they woul dbe lappy, they are only 350hp turbos or there abouts

I don't delete posts unless they are fairly over the forum rule line, don't drag drivel into this. Please stick to evidence.

And... Speaking of which, where is your evidence of said setup? Come on, bit of comparo of results, get this thread going.

OP asked how laggy will they be - answer is without question - very. Results will demonstrate that fact.

I'm all for sticking to "the topic at hand", but broaden your mind a little bit here.

Take into account past questions/history/OP that appears to be asking lots of questions to further his own knowledge

Simply providing a vanilla answer won't help much at all for someone that is eager to learn and be helped.

As for less engine stress, he has a built motor already, scrap that argument already.

Hey Ash, are you calling 2530s VERY LAGGY? The 16G has a smaller compressor then the 18G. I am willing to bet that the setup would be very similar to a 2530 setup. Considering that a TD05-16G is effectively an externally gated T517Z then .... would be interesting.

Can we see a graph which proves that the will demonstrate the other side of the story while we are at it?

Lets get two graphs (doubt we will seen anything that we can accurately compare but lets see if we can) otherwise both sides are speculation.

Lets also get some compressor maps while we are at it and make some more accurate speculations. :banana:

We can look at housings / trims, bearing cores and make a guesstimation, but its still a best guess.

Trust and HKS build their turbos (bearing theories) quite different from what I understand. While the plain bearing is more volatile and supposedly not as responsive, a ball bearing provides some friction by its own nature. Tech docs suggest the cost outweighs the negatives and in this day and age why not.

But lets see who has mastered their craft, its an interesting debate and the million dollar question.

Again at the end of the day horses for courses. :(

this is an old generation kit, it was replaced by the T517Z internal gate kits as the results are similar yet the x gate kits were 4x more expensive.

Td05-16g specs comp (46.5mm in 60mm outer) Ex side (47.6mm and 56)

T517Z specs comp (48mm in 68mm outer) Ex side (49mm and 56)

And yet soo many crack pistons at way less power.

By all accounts the TD05-16g's should spool better than the T517Z's going by the sizes of the wheels. The piping looks like a nightmare though on some of the engine bays I have seen photos of.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
