Tiguan IS38 and Big turbo upgrades

[TheTig]

Good idea for a thread!

Waited almost 12 months after purchase to put a bit of extra life into the car. Absolutely loving the power and exhaust note with all the work done!

1st Step

- Stage 1 APR tune
- BMC hi flow filter
- Snow grate removal

2nd Step
- APR Turbo inlet pipe
- ECS silicone turbo hose
- APR downpipe
- Stage 2 APR tune
- Airflow mod into airbox

3rd Step
- IS38 Turbo
- APR dogbone
- APR turbo muffler delete
- Stage 3 APR tune

Maintenance

Going to perform oil changes every 7,500Kms from now on, in-between 15,000km services

Issues

- Initially with the stage 2 mods had a metallic type rasp out of the exhaust starting at low revs and when accelerating, made the exhaust sound a bit tinny. Not happening now, put it down to new DP and also new rear muffler that was replaced due a rear end accident. Now the've both got a good layer of carbon the issue appears to have gone.

Next upgrade

- Pops and bangs tune, waiting on APR to release it for my car
- Maybe a TCU tune, will see what happens in this space first
- Lowering to improve the on-road stance has crossed my mind, but don't want to be scraping the front end on steep driveways

How’s the fuel economy on these IS38 beasts?

That is exciting mate, can’t wait for your DBV2 IS38 swap!!!!!!

We need someone to make a bolt on Tiguan muffler. I saw Remus one that was custom made for a Tiguan in Hong Kong, but this was not available in Australia. If anyone knows of an off the shelf muffler please chime in.

I did look at dual magnaflow muffler's when playing with my rear muffler which was a recommendation from the exhaust shop.

It’ll be depending on the application of the right foot.

Ditto, just filled up the 1st tank after the IS38 install and Fuelly reported 10.7.

So if you've got a lead foot, it'll suck the go juice like nothing else, but it can still be quite good if you treat it nice

Your build is solid! In terms of lowering your Tig, were you thinking springs or height adjustable suspension compatible with DCC?

Good question, was just an idea at this stage, cost would have to be considered, something DCC compatible would definitely be high if not a mandatory requirement

Hi guys, What's the CTS Turbo DP you are installing cause when I contacted them they said there was no DP yet for our model?
I've come across a company called Stone Exhaust who do have a DP & full exhaust system with valvetronic. The only dealer in Oz is based in Syd & they have quoted me $2500 just for the DP supplied & fitted, but have also said I will need a ECU Tune because there will be over boost. Thoughts on if this is true & necessary & is price tag o $2500 for DP instaled reasonable?

Also I have a mate that works at VW Parts, not promising anything but I can ask him if he can get us the IS38 & pricing. What should I be asking him specifically?

CTS MK7 R downpipe is the closest fit for the Tiguan, that's what I got installed.

Hi,

We know that the APR and CTS MQB AWD downpipes wil fit.

In terms of IS38 model numbers, the models below were prone to failure:

06K 145 702 J (first revision);
06K 145 702 N (second revision); and,
06K 145 722 A (third revision).

So avoid those.

The latest revisons:
06K 145 722 H
06K 145 722 T
06K 145 874 F

Try those part numbers with your mate for pricing. Cheers
