David G (1993 S4)

034 Motorsports sells an RS2 replica turbo. Does anybody have any experience with it? How much do I sacrifice from the low rpm range? Is it worth the upgrade while keeping the rest of my 93 S4 totally stock?

...that if you're going to go for RS2 kinds of airflow, then get a real RS2 turbo.

If you want to move the boost threshold lower in the RPM range, go with a GT2871.

A real RS2 will bolt up no problem in place of your stock turbo.

But you know it's not just the turbo that needs replacing, right? Injectors, exhaust manifold, software, at a minimum. Even the replica would require such things, plus a downpipe, and an exhaust manifold with the proper flanging, etc.

There is a LOT of experience here with turbos other than KKK - don't be afraid of a custom set-up.

With no other mods, you'll give up spool up for no real gain.

that it is quick enough (like a chipped car). Lag is probably greater than a stock K24 but top end is better. Not the normal "upgrade" and is only temporary (as I understand it). Skollie can add his own comments.

And not necessarily a valid assumption.

but not near as much as if you add proper software and injectors. I'd say RS2 turbo and EM alone puts you on par with a chipped car.

I'll race you for pinks, punk.

Unfortuately, I would have to then sell it. The divorce would make funds tight, and I'm not giving up the S-car or the Mercedes.
