For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.
When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).
After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

lS1 CONVERSION COOLING QUESTIONS
GMMASTERTECH Thu Jul 07, 2011 4:44 pm
Hey guys I'm in the early to mid stages of my conversion and interested in the best practices for the cooling system and exhaust. Which radiator and cooling fans really work best 
and whats the proven header/exhaust? My 944 is a 1986 n/a and the ls1 is a 5.7L from a 2001 camaro. My car is a "play time" street driver with air. The ls1 is installed with Erics Kit (all except) the headers which I'm still up in the air on. Thanks in advance for your experiences in these areas. As an Automobile technician I hate buying the wrong stuff and doing the job twice.

Hey man, great to see another Tech! Im a Porsche tech. Really for the LS motors your stuck buying or building a set. One thing i have noticed recently that you could possibly dig into is the 2010 Camaro manifolds look very promising how they dump straight down so far back, and hug so tight to the block, only question is weather the steering shaft would clear... If you have any questions feel free to PM me and ill send you my Cell!!!

Hey Mark, thanks for getting back to me so quickly, being a gm tech makes the ls1 an easy choice. I like the Camaro exhaust but the G8 pontiac seem to be a contender, it dumps farther back by about an additional 1 3/4 to 2 inches. I would like to use manifolds over headers for the reliablity /durablity issuses and the underhood heat reduction . I,m really not sure to do about cooling, which radiator is the best? As a tech we see people do stupid sh*t repeatly and then pay to do it again correctly even aginst our advice. I just don't to repeat that concept.

The Porsche Turbo radiator is proven with the LS1. Easy to add to 85.5 and later NAs I have an 87S. Just get a turbo lower radiator mount and it fits in nice. You will need the turbo radiator fan mount as well. All the stock plastic duct work covers it as well.

cooling system with A/c
GMMASTERTECH Fri Jul 08, 2011 4:21 pm
Thanks Mike , that sounds like the right radiator/fan path, does your 87s have a/c and if so is the condensor and air flow all stock, I have heard nothing but whinnning about keep this conversion cool and just want to play it safe with mine. what if anything do you know about using the stock 944 power steering pump or is the gm Camaro p/s pump the way to go?

Hey Mike another passing question for the guru will the cooling fans from the 944 n/a fit the turbo mounts or do I need entire turbo fan/ scroud set up thanks

How can you tell a 944 N/A radiator from the turbo one? My '87 N/A was supposed to have been upgraded to a turbo radiator but I'd like to confirm. Thanks.
On the PS, there used to be an adapter to use the Porsche pump. But I saw reference to the "last one" having already been made and sold. I'd like to go that route, perhaps if there were 2 orders...

If you are going to spend any time on a track, I would upgrade to the Ron Davis radiator. At 944Fest, a guy had a LS conversion with the turbo radiator on it and it ran hot after a few laps. I had same engine and Ron Davis Radiator and could run 30 minute track sessions and not run hot at all.

You just need the fan housing, the fans from 85.5 on fit.

I have tried every manifold that I can get a hold of , None work without modifications to say the least!
You radiator should have a part number on the top. It will start with 951.---.---.---
you will need the lower mount and the turbo fans.

Turbo radiator works fine on the street. On the track I'm seeing water/oil temps of 250F with it, so I'm going to upgrade to the Ron Davis radiator sometime soon.

So the plan to use my turbo radiator in my track car may be short lived

Well, maybe. My car still has the AC condenser and also weighs quite a bit more than yours. Also I'm up at altitude and the thin air isn't doing me any favors as far as cooling.
Try it, but I'd prefer to see cooler temps than I am on track.

If by coolant you mean antifreeze, that is not allowed in racing.

Lindsey Racing Radiator?
BeaverDeceiver Thu Apr 23, 2015 12:13 am
Hi I am new to the forum. I too have a 86 944NA putting in a LS1 from a 2001 TransAm. I have read a lot about using a radiator from a Turbo. Lindsey Racing makes a bigger billet radiator with or without a built in oil cooler. I am thinking this is a good option since it upgrades the performance from the already adequate turbo radiator. Thoughts? Has any one used one?

Much better fitting options out there, like the Wizard or Ron Davis radiator if you're planning on getting away from stock

Buy a set of headers made for the car, not worth the pain and time trying to adapt manifolds or other headers.
I also just upgraded from 2002 Camaro manifolds to headers with dual 2.5" pipes, the performance gains are significant.

I switched from a turbo radiator to a Wizard and it did not help my overheating issues at all. Then I vented the hood and cooling was much improved. The Wizard is a very tight fit but has all the same mounting points and hose fittings.
That's my $.02.

I looked at the Ron Davis radiators they all seem to be 2 row 1" tubes as is the Wizard. That is what the Lindsey Racing radiator is and it will fit in an NA 944 although the Wizard is a bit cheaper. Rich when you say tight fit how do you mean. Clearing the engine accessory drives or in the supports? I am also looking to do hood vents. Did you cut your hood or buy a fiberglass one? I am thinking about getting a GT racing fiberglass hood and adding their vents to it. If you have a pic of the vents you have. I'd really like to see it.

I mostly mean the supports. The fans go on and space to the f-body accessory drive is reasonable. But getting the radiator in on it's mounts was way more difficult than the stock turbo rad. The Wizard went in, but it's exactly the biggest that would make it in there.
And here are my hood vents.

I recently swapped out my used Turbo radiator for a new Turbo radiator and the difference was noticable. I never hit higher than about 210F on the street (it was about 75 degrees outside), when I was hitting the typical LS 230F in stop and go traffic before. I'll be hitting the track for the first time at Putnam May 9th, so I'll let you know the verdict. I'm caustiously optimistic at the moment though. Running stock Turbo fans at the moment too. Kind of hard to beat the fitment around my hoses and such, so I'm hoping it works.

You get the Ron Davis radiator from Renegade Hybrids. Not sure Ron Davis sells them on their own
