Turbo

[Gomze]

hi friends, I would like your opinion because I am thinking of replacing my first revision mk7 gti turbo, is20 vs is38 ?

Hi,
If you are not looking to gain more power and just want reliability, I would buy a new Is20 and be done with it.
Honestly if your turbo is not giving you any sign of weariness I would let it be.
In any case if I were in your situation I would go for an Is38 new with a life time warranty for roughly $1000.
It looks like you have the supporting mods already…

He’s far from FCP.

 

[Jose_Gti]

You are right, I didn’t notice he’s from France.

hi friends, I would like your opinion because I am thinking of replacing my 06k145702Q first revision mk7 gti turbo, because it is starting to have quite a few kilometers and I am afraid it will explode
I saw that littco was making a turbo hybrid Is20 l340x
does anyone know turbo? opinions ? more reliable than the original?
I'm not especially looking for high performance my car is on a JB4 map 6 soft +5 psi my mods (downpipe 200 cell + forge intercooler)
I await your feedback on littco good day

I had a littco turbo i ran for a few years up until i switched to a vortex xl. While it ran fine when i sold it off, it was alot slower to spool than vortex or even the vortex xl. Mine was littco L470 (they dont make it anymore which is probably basically the same thing as the L480). I would imagine you wouldn't have slow spool issues on the l340x though.

Have you checked if it has any shaft play? If you want to run the Littco on E85 you would need a custom tune anyway. You could get a used newer is38 for a decent price, I know a guy on the Swedish MQB group has tried to sell his for under 500 Euros for months.

hi chris, i checked no play on the turbo shaft
can we manage the is38 on jb4?

Hello Gomze, yes you can run a is38 with JB4 only but limited by fueling control and you will not be able to run very much Ethanol if you also want to run a decent boost add.

I think there are some french tuners that has flexfuel maps for is38 GTIs.

If you want IS20 fast spool, maybe look at a TPC IS20 ??? Currently they do not have any available, but it sounds like you have some time for waiting.

It s good turbo

 

[Diggs24]

The issue will always be JB4 being limited to add fuel via manipulating trims. An upgraded turbo is wasted using a JB4. I don't know why you are replacing a perfectly good turbo. If you are adamant that you will stick with the JB4 stick with an OEM IS20.

@EpicTech read a little more about the TPC20. It doesn’t spool anywhere near an IS20. Can’t cheat physics.

Thanks

hi friends, I have listened to your advice and I will drop the idea of the is20 hybrid
I looked at the side is38 cts, is this a good turbo? yes the ihi is 38 turbo is better?

If you're going to get an IS38 get it from FCPEuro for the lifetime warranty.

just depends on your power goals, me personally I have a hard committing X amount of dollars for 50hp gain, when I add a little more $ and have a more worthwhile gain.

Exactly what I said, but he is from France, maybe the Litco L38x would be a better option https://www.littco.co.uk/l380x-mqb-54-p.asp
1300 Euros for a hybrid turbo it's not bad at all ...
