As we're a small minority in this Tte turbo club, and info is sparse. I thought I'd start a thread that can be used as a reference for us and future owners. For example, I've spent a good few hours searching for iridium plugs for the kit and thanks to fellow owners have the answer so I'll start with this. As things need replacing I will update this thread. Please feel free to add any relevant info you have.
Standard sparkplugs - NGK BKR6E-11
Iridium sparkplugs - Denso sk20r11
Replacement actuator
The Actuator is very close to one used on an old Saab, so I went to forge motorsports and had a custom tuneable one made based on this.
Below are the order codes and all the specs needed for actuator rod and turn buckle.

They're easily tuneable by swapping out the springs for different strength ones which alters the psi at which the actuator operates

Jason/Ardent knows where to find a replacement intercooler I think. I'd sure love to find out where from. My searches aren't returning any results.
you only have to ask.

Don't think any amount of googling would reveal the answer.

I presented them with the original battered TTE intercooler (schweiser???) and they copied it remanufactured it what ever you want to call it. With their more modern core.
I will try and dig pics out. Made a fantastic job. Perfect replica. Installed straight in no fettling required.
Yes they did have the sense to keep the measurements so could reproduce.
Could not believe my luck. They are a mile from my front door.
No kickbacks in it for me, but if you mention MR2 TTE roadster and a short fat bloke, they should recall what intercooler you are on about.
T'da
Did they just re-core it or did they produce the whole thing from scratch?
the whole thing :D
with a bit more digging have pics of it fitted.
Thanks jase.

Standard plugs swapped over today for iridium ones, massive difference. If doing this yourself I did some googling and it recommends closing the spark gap as its turbo'd, so I bought a gap tool and altered it to 1.05mm.
Is it not just the fact you put fresh plugs in?
Perhaps! They are changed every 12 months, so the ones taken out have not really had a hard life. But putting the recommended iridium colder plugs in as opposed to what was previously fitted, has made a big difference, who knew :o
And as they're meant to be a cleaner burn I'm hoping this will help the old emissions too.

Hmmm... There's a tip for Helen's car then :)
Mine is an on bkr5, 6 and 7 haha.. Makes no odds.
A turbo might be more sensitive
6 for turbo
Runs better on colder plugs for sure.
Had colder plugs on the SP and the V6 has I step colder and they're iridium's. Too much faff changing plugs on the V6 every year.
Tte owners can I ask what mpg your getting please ?

@Ardent (https://www.mr2roc.org/forum/index.php?action=profile;u=20018)
Not sure of mpg but full tank would usually get me 260 miles (my daily commute) but when drive hard I'm not sure.
Thanks
@s12vea (https://www.mr2roc.org/forum/index.php?action=profile;u=2340)
Do you know roughly what the amount of litres your fill up is ?
Dan I know my SP wasn't exactly the same but it is similar.
Worst mpg was 27 best was 40 average was 32.2.
Most fuel I ever put in was 40 litres.
It's a 48L or 10.6 gallon tank.
Cheers @1979scotte (https://www.mr2roc.org/forum/index.php?action=profile;u=20268)
Well I've just gone on fuelly and it's early days but my mpg is worse than yours which surprised me.
Wondering if all tte turbo's are around this figure, when driven properly of course.
38 litres roughly. Same old story if driven with minimal boost they will return 40mpg but when drive properly mid to low 20s

When not gunning it the SP is maybe more fuel efficient?
Lower revs for the same power?

Mid to low 20s?
Are you sure?
My V6 averages 25. With a supercharger!
Fuelly says I never got less than 27mpg with a turbo.
@1979scotte (https://www.mr2roc.org/forum/index.php?action=profile;u=20268)
Well it's a weekend car so I'm all about the driving properly. I'm seriously impressed your getting that mpg on yours though
Can be anywhere between late 20s early 30s when playing.
Will expect mid 30s on the run to sywell

Fuelly takes quite a few consistent entries to build a reliable pattern, I was getting 55-60mpg at first on my standard PFL. Showing 29 after the Dales drive yesterday, which is about right. Obviously doesn't help with your TTE comparisons but give it time and it'll start showing more accurate data, especially if you do partial fuel ups and don't tell it.

My fuelly records are based on 14 fill ups and 3300 miles.
Obviously my average is kept up because I do a lot of motorway miles going away for weekends and the like.
One tank of fuel seems to last me all year.
I'm not proud of it but fuel economy is pretty good on this TTE Turbo albeit from lack of use.

What he :protest: said.
Why invest in a car for it to just sit there? ::)
Im always short of either time, energy or money. Last year work was pretty much my whole life so I had neither time or energy. A few weeks ago I lost my job so I have time and energy but can't justify the expense. It's all good - I've managed to find something better so hope to get the car on the road a bit more this year. 🤔 Might even make DD.
You need to attend DD mate, make it happen
Nice thread. SP turbo is near enough tte for me to join in isn't it? With the iridium plugs how often are you changing them? Also what oil change durations are you doing?
Sent from my iPhone using Tapatalk
If its all relevant then by all means post up :)
Oil change I do per annum, i don't do many miles per year as it's a weekend car. I always use Fuchs oil and change just before my MOT.
I used to do sparks at the same time, but these iridium last longer so perhaps every couple of years now.

What happens when you feed these cars normal unleaded rather than the high octane stuff? Jo just filled the car up for me for the first time.
Sent from my iPhone using Tapatalk
It'll run poorly, don't know if it will do damage, but if it were me id put a shot of octane booster in to get the Ron up
Stay below 3.5k rpm.
Hopefully the knock sensor will prevent it blowing up.
As Dan said get octane booster in there.
Is it a proper TTE or does it have SP mods?
It's an sp, not a tte. K thanks, I have some fuel cleaner which I think ups the octane, will have a google. I've not driven it aggressively since but it's the only car right now so it will need to be used. Thanks for the advice!

Odd you should say this. Helen's car just got a standalone put on to run the turbo kit (SP240, very similar to tte) and the main comment from the tuner was that intake temperatures were too high. The intercooler isn't sufficient.
I don't know if it's because of the intercooler being old and not functioning as well or something else.
Dan944 has a custom turbo kit and had the same feedback, so he has taken a lot of steps to get temps down.
So I'm not the only one.
But insuficient TTE IC for 240hp is a different story than for 186 hp

Yes it is, but it does indicate that there's not much in the way of headroom. I'm guessing you're not seeing 50+ Dev, but 38-45. Which is still high but tolerable
I need a TTE IC dimensions. Anyone?

Hello Hitalin
Bit later than I expected but here goes.
If you go back to page one on this thread you will see the one that I had manufacured and where from.
In terms of your question about overheating. No, never had a TTE overheating problem.
To qualify your question.
Is that in the sense of coolant overheating or too high a desirable induction temp?
What is this high temp you hit?
And what is it your tuner can do that others cannot, as the TTE piggy back ecu, like the stock ecu is non tamperable?
What I can say is, the IC lives in a very hostile enviroment and the original IC was in a very poor state. (cira 50k miles) I would suggest that 1/3rd of the vents vanes whatever you call them where, blocked or damaged or both. And mine was leaking boost as had a hole in it where it had worn through from grounding or otherwise. Before my ownership.
Have you closely inspected you IC?

As above, if you go to page 1, you will find who made mine. In terms or dimensions, they made a perfect replica of the original.
They kept the dims for future production. Maybe give them a call.
I still have my original schweizer IC but given the angles involved any dims I could give, would be a bit rough.
Hopefully, rather than D/sizing etc and posting here, pics should be here.

1. I have very high intake temp. Don't have the numbers but my tuner told me that I can't go any higher than stock 186 hp without cooling the intake. During the summer time my car is slower - I can feel it as the outside temp rises.
2. I checked the company you mentioned on 1 st page. They don't have TTE IC dimensions in their archives. That is why I asked for them.
3. My turbo kit is a TTE replica. Same turbocharger/ air filter / IC and fan but different exhaust manifold and piggyback. PB is fully adjustable - that is why my tuner can improve my set up

Ah yes. I remember that being an issue on the tfsi blocks. A lot of people swapped to full alloy radiators. But boost levels on those are far higher than those we run on our 2s

The third post in this thread by s12vea shows the TTE manual, including the piggy back unit. Here are some actual pics of the piggy back ECU and cabling/tubing. Also shows where TTE teed off from the VSV. I see TTE made an extra hole in the firewall and installed a grommet for the vacuumline going to the VSV and the wiring for the decklid fan.
I suppose I could tee off a tube for my boost gauge from the piggy back tube. Anyone else done a boost gauge install that way?
When we had the SP240, it had a T exactly there for what I assume was a boost gauge before we got it.
Eventually we did plumb a boost gauge into it. It worked.
Yes I Used that feed for boost gauge also
Thanks guys. Installed the gauge now. Seeing around 9 psi at WOT in 3rd which is around 0,6bar. Should be around TTE spec afaik.
9psi sounds about right for tte
Bang on the money
Did anyone of you change the stock silencer with a free flowing one? How does it affect boost and/or the engine management? Maybe not at all since the stock cat is the worst bottleneck?

@Ardent @s12vea
The cat is the first bottle neck so might be worth looking for sports cat or decat. I used a spacer on the sensor and never had any issue with engine management light throwing p420.
If you have a turbo it would be a shame to not have an updated backbox. The stock / tte should be fine to 220/230 which will be fine for tte setup

In terms of boost I have no idea, as I have no boost gauge. In terms or engine management, I trust the Mr T Piggy back ECU to sort it all out. I cannot feel any more or less.
In terms of bottle necks, this my depend on what zorst system is currently fitted. Stock, TTE or after market.
In terms of your question. I have changed my silencer for a free flowing one. My bum dyno, anecdotal opinion is, it offers no more than what it can produce. No increase in torque or bhp. But, it gives what it can, earlier.

First you need to remember how the turbocompressor works and then that the pressure is reglated by a boost control valve opening when the set max is reached.
The latter is governed by the difference in inlet manifold pressure and ambient air pressure. This does not change whatever you do with the exhaust after the turbo.
This in turn means that the max torque and hp are set too as they are the result of the amount of boost.
Thus whatever you do with the exhaust after the turbo does not affect max torque nor max power.
However. With a better flow through the exhaust the compressor has less resistance to expell the exhaust gasses. It can spool up quicker. The max boost wil be reached easier and earlier.
Less resistance in the exhaust will thus see the max torque and power reached quicker and earlier.
A side effect is less heat. A faster flow through the exhaust will result in a drop in exhaust system temp. Even lower turbo temp. Thus a slightly cooler inlet temp. This will cause less temp. stress on the engine.
The TTE damper is not a performance option. It is looks and sound. Even the stock engine is at best not throttled by it. It has no place on a turbo; the stock pot is less restricting.
The last thing is that a turbo is a véry effective and efficient sound damper. It used energy in the exhaust gas to do work; to compress the intake air. This work means that the exhaust gas leaving the turbo has significanty less energy even though the boosted inlet has the engine produce more power.
As such the turboed engine needs a lot less muffling so a less restrictive exhaust will not be as noisy as on an n.a. engine.
Petrus was quite right. Replacing TTE silencer with Team Moon Duals (which normally is very noisy) didn't change the noise/tone that much really.
Maybe I've been sleeping during class, but I did not realise untill now that there is a cat in the pipe between the turbo and the downpipe on TTE turbos.

I believe technically still a pre-cat,
