On the side of my turbo are the following numbers - 5326 101 5068 821 226 - does this mean its a kkk-26? My mechanic mentioned that I did not have the original turbo - he is a crackerjack Porsche wrench, so I wouls be surprised if he is wrong. Right now I am wondering if he meant that it was a not the original kkK-26, b/c Ithought that a KKK-26 was stock in a 1986 951. Thanks for your help and comments -

Not sure on the part numbers, I'm not at home, but if your turbo is original(kkk manufactured I should say), it will have the letters stamped on the tag. If it's rebuilt, usually the numers/letters are etched in with a etching pen. HTH.

Thanks Ski - these numbers are part of the original casting (raised numbers) on the Turbo (not etched) - these are the numbers on the side of the turbo not the colored ID plate that I have seen-

Jeremy,

My K26 (factory stock) has 5326 101 5068 1821 226

It looks like the same number, except the 4th set of numbers is 1821 on mine rather than just 821 as you posted. Sure you didn't miss the one?

There should be a aluminum and blue ID tag on the turbo too, which says K26 right on it.

It also has KKK raised in the casting in several places.

Here is a pic of my K26/8 data tag for reference - it's in my '86 now.



HTH,

Thanks all for your responses - they were very helpful. Tom - I did miss a number and indeed the turbo appears to have been an OEM 1986 KKK. Unfortunately, my saga continues as when reviewing my blue id tag - I realized it has the following letters written over it - which explains why my mechanic said it was not the original turbo and based on ski's comment suggests that the turbo has been rebuilt:

GB
OW_

This is in hand written pink lettering (almost looks like nail polish) - the _ represents a character that has warn off and the B could be a lowercase R. I am thinking that if it is an R, maybe it is Grassroots Motorsports. Does this look familiar to anyone? Is the pink lettering or these letters standard for a rebuilding company? My guess is it was rebuilt, but my understanding through reading other posts is it could of been rebuilt to be a K-27 - can anyone shed some light? Again, I am hoping to figure out the type of turbo so that I can purchase the right Guru chips. Thanks again -

I also have the K26/8 in my 86 but I was under the impression that the only way to tell is to measure the hot side if it's been modded. Is it true that all the plate numbers will be the same for the K26/6 and 8? I went through this awhile back trying to confirm what the seller had told me when he never came up with the promised paperwork on the car. I believe mine might be a modded 86-87 K26 with the #8 housing changed out. Did the original Turbo S unit have a different plate number than the 86-87 if it came as OEM equipment on the 88+?

Pauerman

Here is the data tag from my K26/6 that was removed from my '86 car. I guess you could reference PET to see if the #'s on these data tags reflect turbos used on 88-89 "S" cars vs 86-88 non "S" cars. The real proof of your car having a K26/8 will show up on a dyno. I put down 292 whp / 322 lbft with mine - don't think 26/6 could do this.

KuHL 951

The only difference I see is the PET number is 951 123 131 02 for the 86 on the K26/6 and ends in 03 for the 89. Even PET shows an 03 extension on the part# for 86 on the M44.52 engine, wonder why this would be (early Euro)? It's odd your 86 plate doesn't have the part number. My plate number is the same as your K26/8 so I guess that's good enough for me. I've never dynoed the car but know it pulls better than my friends 86 with K26/6. Thanks for the info, I'm still learning.

I wonder if the pink lettering is a salvage yard (junk yard) marker? Junk yards use colored paint-like pens to mark their parts. Is there a german car junkyard nearby with the initials GB (Gr) or OW_?

Pauerman: Wow, excellent numbers for stock turbo. I take it with the Tial you were able to hold most, if not all, of the 18psi to redline?

Stock exhaust? AFM or MAP/MAF ??

how much of that do you think was do to head work?

Pauerman

Todd, I quoted an incorrect hp figure previously - I made 273 hp instead of 292hp but the torque figure of 322 lbft is correct. This was at 1bar.

My results were with a stock engine, SFR test pipe & catback, LBE, shimmed stock WG, GURU v.7 chips and AFM w/ K&N. Using the shop's boost gauge (tapped into one of the vacuum lines) my first 2 runs registered approx 1.2bar and the stock WG was suprisingly able to hold it to redline - my stock unit performed very well. This boost level generated 277 hp and 343 lbft. My dyno runs were made on a Dynojet at Technodyne here in AZ.

I've been playing with the Dynojet viewing software and don't know how to get my dyno charts into a format where it can be viewed here. Anyone got any pointers?

I am very impressed with the capabilities of the K26/8. I'm looking forward to seeing how this turbo performs in my '86 car. It's got a Tial 38, Accuboost and Guru 18 psi chips (24 pin programmed for 26/8). I've almost got it back together, so it won't be long before the "for sale" sign goes up.

I was hoping that the pink lettering on the turbo would sync up with someone's "trademark" for a rebuild. I have some other questions based on the additional commentary on this post. I don't have a 951 part number on my ID tag which I thought was unusual - what if anything does this mean? 2Tight - any chance you were able to determine the answer? I will check my PET but what exactly was the M44.52 engine in a 1986? -
