HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


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 …

I have a fully restored 951. There's no way I would race it.

Until recently I didn't realize there was a significant community of 944 owners who had performed v8 conversions. I'm intrigued...sounds like a great idea for a track car.

Questions:
1. Is the preferred platform the early 944, late 944, or 951? (which is the net least expensive when you consider the cost of car, clutch, brakes, radiator, etc.)

2. What are some performance metrics that members here have gotten from their conversions, and what was the set u? In other words, what is a good 0-60 time and top speed, and what motor and other things were used to get you there?

3. Is there a "standard" conversion for which I could buy all necessary adapters?

Hello, this site has all the info u need. TPC has all the right parts you could need. High quality and a good cost. all 924 to 968 use the same base platform. they changed the body styles a bit and the factory engines.Its well worth the change for the performance and the reliability.There are a lot of smart people on this site, so answers come easy to questions. Good luck join the growing number, you would not regret your move.

IMHO, for a track car you would want to find an '87 or newer 951 without the M30 suspension. This gives you the newer offset for better wheel choice and front brake upgrades. Tranny should be a limited slip unit. While the 951 tranny can tolerate up to 500 hp on a road course, it is not made for clutch dumping. Top speed is a function of power and choice of 5th gear.

You have a large selection of LSx engines to work with. The LS1 and LS6 have been race proven and are pretty much bullet proof. A stock LS1 gives you about 325/325 to the rear wheels. With minor modifications and tuning 400 to the wheels is easy to achieve.

As Kevin said there is a wealth of information on the board to help guide you in making a decision on which engine to use as well as other conversion parts.

So far the information I've gathered is an 85.5 or newer 951 is the way to go as far as already having the parts you need. The 951 transaxle (with 5th gear swap from an NA 944) and radiator are desirable for the conversion. The trade-off of course is cost. 951's are inherently more expensive. Newer cars may be more expensive but have fewer things broken and vice versa.

Where I am on NorCal there are quite a few 944's for sale. S's and 951's in decent condition are almost always $3k to $4k more expensive. NA 944's can be had for under $2k. I got my 86 NA at the lower range of that. It was in great condition but undrivable due to a blown head gasket - so a great candidate for a swap as far as NA's go. Your best bet is to shop around and see what the prices are doing. Don't be afraid to offer low on a car. They're old and really it takes a certain person to even be interested in one.

Unfortunately I can't answer that as my swap's not done. But I'm going with an LS2 if it matters.

The short answer is "no". There are many variations on the swap. Much of it depends on what your end goal is. The build requirements for a dedicated track car will be much different than a street car. It's best to decide what exactly you want before you start and plan accordingly. A project like this can easily blow out of proportion if you don't set goals and stick to them.

As to the long answer: The most difficult parts to build and/or source are provided by Eric at TPC. These are motor mounts, oil pan, conversion clutch, and a handful of other things you're going to need. If you've got access to a welder and/or mill and know how to use them you can make some of that stuff.

Everything else includes cooling, wiring, brakes, and the remainder of the plumping. Those things are generally left up to you to figure out and complete as they're specific to what you want to accomplish. These have been solved in different ways by the various people on the board who've completed the swap. You should browse around to get a feel for what different people are doing. There are a few detailed build threads on here that can provide a lot of information.

And you can always ask more questions!

Please don't take this as a criticism but do not use a pre '87 unless you get it for next to nothing, because the front spindles, hubs, and rotors are the smallest of any 951. The offset (a-arms) was only used for a year and a half and would need to be converted for decent brake and rotor upgrades.

Converting an early 951 front end would conservatively run over $2k with a-arms, spindles, hubs, and tie rod ends. Then you would have late offset in the front and early offset in the rear which means larger spacers in the rear to fit the late offset wheels.

I know about this because my car is an '86 and I did the front end conversion two years ago.
