Good morning folk, I hope everyone is keeping well ;D
Now I have the turbo, I'm after some advice please, how warm should I let the engine get before putting my foot down a bit?
Currently, I'm up and out at 04:40 so it's jump in the car an go.
I just have the normal water temperature guage and keep it below 2.5k revs until the guage gets to working temp.
Funny thing is, I can hear the turbo start to whistle around 5 mins into my journey at around 1.8k although I didn't think it starts until 2.8k?
On the flip side, how long should I let it run and cool down once stopped?
Probably just being over cautious on both accounts but I do error on that side as I don't want to break it :-\
Many thanks for any advice x x
Ideally you want an oil temp gauge. You will be surprised how during the cooler months the oil temp. lags behind the indicated water temp.
The turbo will spin rather fast at idle even. It is only at higher revs/more throttle that it start spinning thát fast that even air gets ´weight´, kinetic energyu through centrifugal force.
As to the idling after stopping, that depends on how you drive the last miles. Pottering the last stretch home, it will not be hot so no worries. Stopping for a coffee while on a blast on a hot day, you want to let it idle a minute or even two.

Agree with Petrus ideally you need an oil temp gauge and it could take 20 minutes for the oil to fully warm. The water should be up to temp in around 5. I've had oil temp on a turbo 2 and it surprised me how long it took.
If you stay off the boost for 5 min on the way home that should help.
Leaving it running at idle for a minute or 2 is OK too. Id open the engine lid. You could also look into fitting a fan like tte kits have.
shout if you want the shopping list that I used for my setup.. the issue becomes once you have one gauge.. you really do want more.. guess you'll also want a turbo timer?
Yeah as they've said above oil gauge for temp and pressure.
As a general rule of thumb my oil takes about 3-4 longer than the coolant to get up to temp.
I feel I ought to contribute, but don't have anything to add. No gauges. Nothing.
I Just play it by ear.
And from distant memory. Nothing in the install guide or the additional service booklet.
The cooling down is taken care of by the fan. The warming up is by gut feeling.

Thanks John, I'll have a peek if I may, reason I went without gauges is they are all bolt on and I don't find any of them aesthetically pleasing inside the car.
Can meet up sometime soon if you'd like to have a look what's been done. December sometime 🙄
I think if I was to get gauges (although Ardent manages without, I should be able to, if I'm careful, I'm sure) I'd go for a bank of three. Seems that would be symmetrical to me.
Boost
Oil temperature
Oil pressure
Would they be the most useful?
Thanks for the advice gents

Hide them in the middle cubby or look into something with Bluetooth for your phone.
PLX do a multi gauge system one gauge can display different data you could even use your phone.
However I never got mine to work properly.
Ardent has a tte its not really the same as having a home brew kit.
What turbo is it and how much boost does it make?
Boost gauge is the most important tbh you don't want to see more than 10 psi from a T25 type less from something bigger.
Remember a lot of people with turbos never have any issues at all. But you have to look at the mileage they do and if its just a weekend cruiser. If your daily driving in all conditions your more likely to come across issues.
I personally don't recommend daily driving a modified 2.

That sounds like the experience of "tears" rather than years.
A modified 2 if set up correctly after the initial "shakedown" should be reliable as a stock 2
I've daily driven many turbo 2s and never had a major problem while using for my usual daily tasks
A boost gauge is worth it's adding to keep an eye on things
Just respect the car and maintain accordingly

Thanks for the info Scotte, this is the set up
Water cooled T25 turbo
Air to air intercooler
Sports exhaust
440cc injectors
ECU and electronic boost control
2.5" sports exhaust with twin tail pipes
Helix Sports clutch
Circa 225bhp
I run it mainly on setting two so probably around 200.
I have a back up micra sports for wet, icy, snowy days, so it's not really a daily, plus I only use my car for work two days a week (three max).
On level five boost I was told it's just shy of 10psi.
My new (to me) engine is a later model (07) 1zz with forged pistons, I'm told.

Steve with all due respect you've never kept one long enough for problems to arise.

T25 is just a generic term you need to know what it is if you ever need it replaced.
Which ecu?
You've bought and engine with forged pistons? They are circa 1k plus fitting. I think you me revised pistons to help with oul gumming issues.
This sounds very much like my old sp240 kit.
Rotary dial to change maps.
Unichip piggyback ecu.
440cc injectors
Keep an eye on oil level religiously.
Sometimes the seals go and you burn oil.
Sometimes the oil drain isn't right.
Be careful I changed turbo at least twice.
Sorry Scotte, just checked on what was said. "Forged rods" not pistons.
I'll check to see what further info I can glean.
Checking oil once a day when in use at the moment.
The turbo was reconditioned before installing.
Yup rotary dial. 🤠

Forged Rods are good what ecu is it?
Who did the turbo recon do you have receipt?
No receipt, wasn't me who sent it.
Turbo is Garret T25 (as fitted to Saab 9000!).
ECU is Dastek Unichip + with injector overdrive module and MAP sensor module. With electronic boost controller of course.

So you've bought an sp240 kit then mate.
Its a tb2559 same as the tte.
Just more boost and bigger intercooler.
And midland turbo performed the refurb

Níce!
Probably best for me that the bureaucracy puts a stop to it but I do desíre that; both the TTE and SP240 kits.
Congrats Garfy!!

In many ways you could be right but..... my green one was daily driver for two years and never a skipped a beat plus I've clocked up many miles in turbo'd 2s and pretty much trouble free
TTE / SP kits are possibly the best set up for dare I say fit and forget, but will depend how they are maintained and respected during ownership
Quote from: s12vea on November 11, 2020, 15:50TTE / SP kits are possibly the best set up for dare I say fit and forget, but will depend how they are maintained and respected during ownership
Again Steve I hate to disagree but my SP kit that I bought from you and was installed by Matt gave me plenty of grief.
Not complaining just stating facts.
Greeny was a tte too not an SP less boost different electronics.
Like I said before many owners drive like your granny and put 3k miles on per annum. My SP kit did over 5k miles just to ROC events in 12months.
These kits are all really old now and will need looking after. Glad Garfy has bought a rebuilt unit.
We each have different experiences I guess, maybe I drove like a granny who knows.
If the OP turbo has been rebuild it's reassuring for peace of mind and should help with reliability going forward.
Each car will have its own story to tell, let's focus on enjoying the good times
As a fit n forgotter.
So far so good.
I never really think in terms of looking after the turbo.
The engine rarely goes above 5k.
Being a torque junkie, after 4500 it drops quickly. So just ride the wave.
Adore the initial pull from 2ish up to 4500 change, drops a 1000 into the peak at 3500 and 4500 and change ....

This is only relevant to a tte.
An SP makes around 10psi at peak torque which drops towards 7psi at the limiter.
It never feels anything less than thrilling to rev it out.

Oh dear, I've enjoyed hitting the rev limiter a couple of times already as I wasn't watching and it gets there soo quick 😁
It seemed not to stop until I hit it?
It was quite annoying really, now if only I had an engine that revved a little higher with the same boost 🤔
😝

AHA, is THAT why I run out of revs? I have the wrong turbo and need one that makes me change gear earlier 🤔😉😁
