[s-cars] Re: RS2 Turbo's

[Lewis, Gary M]

Greg et al.,
The original email I posted on Innovative's RS2COMP++ (what I call it) is attached.

If you don't want to read it, the readers digest version reads:

Call Ola at 805-526-5400, tell him you want what Gary Lewis got.
Web: www.innovativeturbo.com
Price:	$950 exchange (1986-1988.5 5000tq turbo as exchange)(I'd do this.  Junkyard turbo's are ~$50)
		$1,600 outright
What you get:	

Ola rebuilds the turbo to new.  He machines the cold-side housing by cutting off the intake and putting on another so that the opening is around 50mm.  He machines the inside of the cold-side housing.  All this machining allows them to install a larger, newer type design compressor, which is proprietary, they are using it on their Porsche program, anything that uses a K24 or K26, C2's 944's, etc.

Complete bolt on to the S car line.

With all the RS2 goodies and 26 psi VMAPD s/w full boost is achieved at ~3,400, 3rd gear (my car spec).  It builds from about ~2,400 however, so it is very linear boost wise.  I'm hoping the FMIC and RAIS will lower pressure loses, and give me ~200 to ~400 rpm back w/respect to full boost.  I'd like to get 26 psi at 3,000 rpm.

Some primary differences between this turbo and the RS2:

RS2 has the smallest of the K26 turbine wheels.  The stock K26 5000tq turbine wheel is larger, which flows better at high boost.  Compressor side is the larger K26 housing, with the larger K24/RS2 sized intake, and a MUCH larger compressor wheel.

I am not an agent for Innovative, I paid them for my turbo.  Just a happy cutomer.

HTH,

Hi Audifans,
Innovative turbo has a new turbo design that is for sale.  The owner and operator of Innovative Turbo has been working diligently with me to produce a turbo for the Audi 20vt motor.  I upgraded my motor to Bob Pastore Spec (tm), but I couldn't find a stock RS2 turbo, regardless of price.  A lister from back East (I'm in Los Angeles) suggested calling Innovative.  I did and told them my goal was same or better performance as the RS2 turbo, same or better reliability, and straight bolt in ability.

I went over to the shop (like 15-20 miles away from my house, nice.)  First thing I see when I walk in the shop is an Inconel exhaust manifold for a 20vt5cyl lying on the bench, an Audi factory race-works K27, and a host of other Audi stuff.  Turns out the owner (Ola) is a real Audi buff.  There are turbo race cars (track and drag) all over the shop.  Awesome place, a turbo racers wet dream.

Anyway...

What Ola suggested was to take a water-cooled K26 from 1986-1989 5000/200TQ fame, open up the cold side inlet to 48-50 mm size, with some additional machining to add a larger cold-side compressor wheel.  He did this for a 944t customer and the guy was blown away at the difference in performance.

We did so, and it bolted straight into my 1995.5 S6 wagon.  Performance is spectacular.  I'm getting 26 PSI in the 3,400 to 3,600 range, with hard pulls to 7,000 RPM.  The turbo just doesn't give up.  I'm seeing 29 PSI in 4th and 5th.  What the larger cold-side housing and compressor wheel does vs. the RS2 (in Ola's turbo language) is "upgrade the stock K26 to RS2+ spec, with better than RS2 efficiency and better delta P across the engine".

I let Ola drive the finished product, and he said it was a good trade off vs. the T04E/K26-8, especially considering the attraction of the bolt in ability.  More low-end, and pretty close top end performance.  The number 8 exhaust of the hybrid is really nice on the top-end, but it makes the transient boost more dramatic (nothing or everything) than the new Turbo I have.  What the new turbo does is build boost smoothly and early.

The price he quoted me was $950 with core, or $1,600 outright.  What you get is rebuilt internals, new compressor wheel, and machined cold-side wheel with the exchange option.  Ola's number is 805-526-5400.

Huge disclaimer!!!!!  I am NOT an agent for Innovative Turbo, and I will not be paid or compensated in any way from this email.  I paid them to do my turbo.  In fact, Ola did not even ask me to do this, it was my idea.  I'm just a super happy customer.  These guys were great, and bent over backwards to help me.  The car would still be parked if it wasn't for them.  So if you need an RS2 (or bigger) turbo, super KKK reliability, and bolt-in ease, call them.  I highly recommend this turbo.
