Upgrading 90Tsi

[khonfahm]

Hi guys,

New person here on the forum.

This is probably going to sound very stupid, but I thought I may as well ask.

I have a 90tsi Vw golf mk 6.
Is it possible to add a supercharger to make it the same specs as a 118tsi?

Also, are there any big upgrades that are available for this car(90 tsi) besides the ECU tune?
Also, which Blow off Valve am I able to get ? ( I really like the noise of a nice turbo car, with a well tuned bov)

TBH probably better off going with an ECU remap because of the ease of hiding from the dealer if you have any issues during the warranty period and secondly during servicing if you choose to get it done at a dealer.

If you go fitting an aftermarket supercharger they can argue that faults that could be associated with that are warranty voided and then your stuck with an expensive repair bill.

With the tune you could always add an intake from one of the big companies like GruppeM, Forge etc for that tiny bit more horse power.

Hope that helps.

Hi mate been looking at the same thing (well not supercharger) but have been told biggest issue is that turbo so restrictive (same as 77tsi) and that d/p etc wont boost much if at all. So im just going for the tune on my 90tsi

it all depends on how much cash you want to splash.

Mild:
Bluefin ECU tune and Carbonio APR intake (if there's one for 90TSI) would do a good job.

Extreme:
CPC in Artarmon did a awd conversion and put different beasty engine in a Mk6 Golf Wagon (see this month's Motor magazine hot tuner challenge section). total cost is $120k per the magazine.

Thanks for the response guys.

I guess I will go look into the ECU tune. Do you know if that affects the fuel consumption a lot?

Mate, you are a legend. I only knew about APR and REVO tuning... have never heard about super chips... was always a bit iffy about doing the APR tune since my car is the 90kw version with no cruise control. So I can't even switch between the programs...and am expected to pay $1300....

Did a bit of research and saw that with the bluefin tune, you can turn it on and off physically with the unit they send out to you. Same power gains. $700 ish! Going to call the Brisbane dealer to see if I can work get one today!

I'm looking at getting my 90TSI tuned as well. I've read quite a lot about people with 118TSI and GTI getting tuned, but not so much about the 90TSI. Has anyone on this forum had the superchips remap done on their 90TSI? And if so, are the gains noticeable and worth the $$? Any feedback would be much appreciated.

Hi khonfahm

Talk to Jmac about tunes. He is in Brisbane and highly recommended.

I believe you can get the same output as the 118 from the 90 with a tune.

The 90TSI is definitely worth tuning, but it is difficult to squeeze any more than around 110kW from the engine due to the very limited size of the turbocharger.

In the 77TSI, the turbo is not working as close to the limits as it does in the 90TSI; as such, we rate our 77TSI tune at 100kW and the 90TSI tune at 110kW - but even then the 20kW gain is very noticeable and really makes the engine come alive. Our tune also remaps the throttle mapping for sharper response/less delay when stabbing the throttle. Combined with improved ignition timing curves all across the range, the end result is a car that is not only more fuel efficient during idling/low loads but with a strong wide powerband at open throttle.
