Title: Audi S3 intercooler upgrade
Post by: Sammy on March 26, 2012, 01:47:28 pm
What is needed to install the s3 cooler on a gti? Also is there any modifications required?

Just the intercooler and the two pipes.

Depending on your model year you may need to alter the pipe on the side to fit

What two pipes are needed? Also I have 2005 would that need altering? Do u mean modifying one of the pipes to fit?

This is what you need

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fwww.jkm.org.uk%2Fperformance%2FMisc%2FMisc_Performance_pictures%2FTFSI-images%2FOverviewpage%2FIntecooler%2Fs3corejkm_big.jpg&hash=94a296c754574da1f8b350fc24ab3708c0ff6bdc)

The connector on the end of the Turbo discharge pipe is slightly different depending on the year. If you get the year where it's not a straight fit (RH Pipe in the pic) then you can cut the end off and use a connector from forge to get it to fit.

If i can find the pic of the differences i'll post it up :happy2:

S3 Intercooler - 1K0 145 803P

Left Pressure Hose - 1K0 145 834 AA

Right Connection Hose - 1K0 145 832 L

Not sure wether that is for the old one or the new one with plastic end tanks. I would have to check with ETKA which i won't be able to do till later this evening.

It must be where the Mk6 GTI gets the extra 10 bhp than the MK5 GTI lol

Really interested in this mod. Does anyone know how much this is roughly from TPS?

Forgive my ignorance but where about exactly is the intercooler mounted?

....Behind the 'water' radiator.

[Where's the water radiator mounted? I hear you say]

The whole front of the car has to be removed to install it - Hence the labour costs.

IIRC it sits between the radiator and the aircon radiator.

Easy once you get it looking like this lol.
Theres a guide on the site somewhere to help you on your way.

There's a famous thread of a member here (illyun) who took over 11 hours to fit his intercooler and then had quite serious problems resulting afterwards. IIRC, JKM helped him out in the end.

I presume the S3 intercooler is bigger than the ED30 one and improves cooling.

Any other benefits?

Thsi thread people are saying only two pipes, But i just read somewhere you also need some sort of M16 bolts?  :confused:

I believe that's only with the metal end tanked cooler.

I removed a mk6 cooler to fit a ths cooler and I don't remember it being any different to the standard mk5 cooler.  Would be nice to see the coolers all next to each other for comparison.

Mk. VI GTI + R is thicker than Mk.V GTI. Same thickness as the old S3 IC.
Just plastic end tanks but improved core.

Same thickness as old S3 intercooler or do you mean same as the latest S3 8P?
Title: Re: Audi S3 intercooler upgrade
Post by: the bruce on April 27, 2012, 12:09:45 pm
Both.

Mk.VI GTI = Mk.VI R = Scirocco R = current S3 2010 on = TT-S and some more

All these have the same IC currently. This IC has the same dimensions as the former full metal S3 IC.
