Anyone know what make of turbo this is? Garrett? KKK? Is it water cooled as well?

Chris Prack

I recently installed one of their turbo's on an 89 model. It is not water cooled and looks to be a Garrett based.
It spooled up quite nicely and my customer is very happy the the results.
I would not hesitate to use one again.

what hot # did you give him? what trim, and what was the size of the comp wheel? <img src="confused.gif" border="0">

I am going to install one next month, LR stage V. It does start as a Garrett but Vision does its magic on the compressor.

Look for an ad in the upcoming Excellence for Kokeln about their "kit"; stage V turbo, their chips, injectors, Kokeln intake, LR wastegate, I think 18 psi(?) and made 360 rwhp.

I am not at work today and I don't remember off hand what the specs for the turbo were. It was Kokeln's stage v turbo as delivered from them. It is a nice unit plus I got rid of the annoying electric water pump.

You should re-think that statement. The longevity of the turbo is mostly based on the cooling of the bearings so they do not get oil coked. After shutdown, the heat soak, especially from a large turbo, can bake the bearings since the housing temperature is much higher than the coolant or oil that will be passed through it. Ultimately, I think a small pump that could flow oil from the oil cooler into the turbo for 30-60 seconds after shutdown would be best, but using the coolant slowly reduces the temperatures. A simple turbo timer that idles the car for 30 seconds are selling like hotcakes at some $200. Problem is that you still have heat from the exhaust flowing into the turbo, not to mention your car sitting there running. That little pump is one of the most clever devices on the car.

Sure, every once in a while you need to replace the pump and plumbing. Aftermarket pumps can be had for $75 and are virtually the same thing. You can get the OEM for $165, or attempt to rebuild it yourself (I have and had success) and get some extra milage out of it.

Yeah I thought about all those things too Perry. What I came up with was the wrap the hot side of the turbo to prevent heat soak from everything but you will still get some from the hot side on the bearings. Once I get the line off from the top of the turbo, I am going to try to weld in a larger "bowl" if you will that will hold oil and then slowly drain after engine shutdown to provide some cooling to the bearings. I also just purchased a 2nd generation RX-7 oil cooler that is 23" long X 5" high X 1 3/4" deep. That should aid in some oil cooling over our small one.

I've always even cooled this one down even though it does have the water added,,old habit from the early turbo Z days. I'm also going to split my x-over pipe, just where it goes up to the turbo so I can break all that if the oil pan gasket gives way again or to change rod bearings. I'm getting LR to split my crossmember.

I have this turbo on my '86 951. Its made by Turbonetics.

Here's the low-down on it:

- 60-1 HiFi Compressor side
- Stage V Turbo side

I'm having my car dyno'd next week.

I may be short a few ponies since Im using a stock cat back, but other than that I have all the necesary mods to make some decent power.

This turbo starts to spool around 2600rpm. Full boost at about 3000rpm and pulls strong to 6800rpm(It would probably pull beyond that, if the valve train could handle it).

Right now I'm running about 18psi.

Hope this helps.

keep us posted on your dyno results!

Forgot one thing... this turbo is water cooled.

Its pretty much a bolt-on as well(As much as you can get, given the difference in size between this turbo and the stock unit)

I'd post some pics, but i don't see that option in this webboard.

Depending on how you get to the forums, you might not get the background menu that has this option. The URL below has the correct background menu.
