Intercooler for 162Tsi

[brad]

Just curious if anyone has fitted an upgraded intercooler to their Mk2 Tiguan. Is there any difference between the GTI and R intercoolers and if so, which one has fitted. Lastly, how much did you pay to fit or is it easy enough to do with a spare day at home?

I fitted a Golf R Intercooler to my 1.8tsi Octavia about 5 years back. It was a cheap upgrade ($100 2nd hand IIRC) and took me from a 20mm core to a 25mm. The end tanks flow better and there are more tubes as well. The best thing is that it looks totally stock. You'd have to be the worlds leading expert on the marque to know it had been changed.

I did the change by myself with basic tools and there was 5-6 hours steady, logical work. My 80yo father stood there watching with his jaw on the ground but he's never been much of a spanner man. I did need a 2nd pair of hands a few times but even my kids would have been able to provide assistance.

VAG cars are all interchangeable. I'd be very surprised if the R/S3 IC didn't fit.

If you're going to pay someone to do it then go all out and get a big 40mm alloy unit.

BTW: It isn't stage 2 without a bigger IC.

All back together again!



Only one minor issue trying to find the connector for the collision sensor. Eventually found it underneath the intake inlet. Of course if I didn’t have an aftermarket intake installed it would have made it a lot easier finding it!

Initial feedback is that the intercooler hasn’t effected the low end performance at all and bum dyno says it’s quicker at the top end.

I’ll get it on the road on the weekend (hopefully get a coolish morning) and run some 0-100’s. I suspect it may be in the 5’s now... and only with hardware mods.

Nice one. Good to hear low end performance isn’t afffected. Interested in whether there are any 0-100 improvements, probably more noticeable with a tune/turbo swap. How much was the IC landed including taxes?

Yes I was concerned that the larger volume would cause a delay in boost coming on but seems no real difference. Certainly not noticeable when driving.

The top end is definitely freer and feels like it wants to go now / run a lot more freely at higher rpms.

I sourced this from the local distributor (Performance Brands Group) but it was shipped direct from Germany.

Well as I originally suspected putting a significantly larger intercooler on actually has had a negative impact on performance. Not a lot but a little bit.

Ran a 0-100 this morning and was 6.14s or 0.1s worse than before.



This was actually what I thought was going to happen with a larger volume intercooler to fill.

It doesn’t concern me that much as I know the stock intercooler is going to be too restrictive at higher flows once the new turbo is fitted and the car is tuned.

It was pretty hot in Melb @ 37 degrees, what was the temp in SA....do you think that might have contributed to the slower 0-100?

I went out earlier in the morning and it was 23-24degC so I don't think it was ambient temps related. Temps were similar to the previous runs within a few degrees so I don't think that was a major factor.

It's funny the top end feels better but is actually a little slower. I'm not surprised as this was actually the result that I was expecting. I'm actually happy that it's not a significant effect given that I'll likely be driving around for another month or 2 like this.

Probably helped the other day when it was 41degC but I don't ever push it if i don't need to when it's that hot.

You will only see an advantage with the bigger cooler and stock turbo if you got a remap.

With stock everything you will have less heat soak now especially if you were driving around in Melbourne over the weekend.

Yes unless the stock intercooler is undersized it should be fine for standard map which this test supports.

Agree that it’s only for higher power applications that you’ll see a major benefit from the larger intercooler .
