having seen a removed K03 and IHI side by side, i would confidently say the IHI is larger.
But its only larger by a tiny amount, talking 5-10% in physical size.

My GTI 2012 seems to pull hard to the redline at 6000rpm..... very different then the brickwall feeling from the MK5 i drove 2 years ago.

Thanks for the info Smelly..

If you dont mind could you upload us a pic of the IHI Turbo ...all pictures Ive got I can not see the whole turbine of the turbo...just for a visual comparation.

Thanks in advance

cant help with pictures, i just remember it because i was having my Skoda Yeti mapped at MTM Taiwan and they had tons of MK5 gti K03 turbos that were broken and there was a MK6 gti which was having a K04 swap installed, thats how i saw the IHI.

Ok Smelly

Dont worry, little by little well see more IHI upgrades to K04, Garrets...etc...someone could take a pic for us

Today is the first I have heard of IHI, when did people find out that the TSI uses IHI and not ko3?

I have my old turbo that I can snap pics of as soon as I get back from deployment. Right now the only photos I have of it are a side by side shot with my new ko4 but will have to post that once I get to MWR if you wish (Military network blocks photobucket among other things ).

When the TSIs first came out there was a lot of speculation as to power delivery. The TSI has more midrange power and yet died even more so than the FSI after 5.5K RPM. Once Big turbo guys came into the scene they began noticing the differences in turbos and eventually just put two and two together.

I'll take pictures of the two turbos side by side tomorrow during my K04 install.

Looking at the compressor side of the turbo just visible begin the heat shield near the oil dipstick you can make out the lettering IHI on the aluminum casting.

It could be great if you can take pics of both turbos: IHI vs K04 in order to compare them.

Having a k03 in my hands (see pic attached in this thread), Id expected a bigger turbine than IHI, right now I could not firmly say what turbo is bigger, I would say at least they are the same, in terms of turbine size.

I agree the TSI has better midrange torque due to a better HPFP, but I also think the TSI has a better TOP END than the FSI. Confirmed in the dyno and road.

Anyway in almost every rpm range IHI flows 0,1 bars less than the k03 but performs better in terms of whp, that could means two things: a better engine managament EA888 > EA133 or a bigger turbo IHI > K03, more power with less air flow.

Regards

Haha, this is what happens when you fall out of the loop .
I don't have any detailed photos of the two, just one of the two sorta hanging out
Looking forward to a detailed comparison of the two.

To be honest I never paid much attention to it during its short marriage to my motor, I had all the APR\ko4 goodies within 1K miles .

Someone with a MK5, MK6 and some ingenuity should bolt up the ko3 and IHI and do dyno pulls with each turbo on each car in the name of science; practicality be damned .
Maybe it's a little crazy but it would make one hell of an interesting read.

Jaja Ok, we are discussing here the performance of the IHI Turbo.

Do you have any tech data about it? Wed appreciate it.

I'm afraid that from my present location I can only post this pic and assume the role of a spectator...



It's a crappy cellphone shot but maybe it can give something to look over while awaiting much better photos.
