I am going to K24/26 but question first

I have found a company in the UK to do the mod and they have come recommended. I am unsure of who to use for Tune.... (Marksi?)

Before I do this..... I have a slight judder at low revs:

lifting off the power
easing on the power

And sometimes when pulling away at low speed.

The car has a map as it boosts to 1.0bar, I am not sure of the vendor but I am thinking it could be the current map? or flywheel? Turbo issue?

The car is smooth when changing gear and using the clutch.

Can anyone advise what the problem might be?

I have had a new MAF and plugs in the last year.

Thanks!

K24/26 is an old set up... used for 7 years now... very entry level....
do a k24/18g upgrade and it will blow that other turbo away. it does not need injectors just a 5 bar. We can also do a K24/20g but that needs more upgrades to use it...


Judder? what do yo mean> coming from exhaust? other?
you mean hesitation?

The K26 family has many members. It has newer additions, the new KKK compressor wheels are very efficient with extended tip, and swept back blade designs which rival if not exceed other manufactures right now. Yes, there are older K26 compressor wheels on the market, but there are also new wheels that are lighter and have higher outputs vs other "trend" branding.

The 18G and 20G are getting long in the tooth, and closer to the Garrett TO4E in design. Which date back almost 20 years ago.
So what is the ultimate spec for a K24 based upgrade now then?
