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 …

Hi everyone,
I'm relatively new here and thought I'd share my current project with you all.

As the title states I'm swapping a Honda K24 into a 1987 944s. I've pretty much just been mocking an engine in there and figuring out what I need to do from there.

I originally want to do a Honda J35 v6 swap but that was going to require more firewall and hood modification than I wanted to do at this time.
The first picture is of the J35 sitting in there.

And this is the K24 mocked up. The bellhousing adapter will start next week with any luck.

Are you planning on staying naturally aspirated? Is that the same engine as an Acura TSX? Good luck with the swap.

That's a cool project! Have been following a few of these swaps in Civics, seem like really capable engines. See that it sets pretty high. Is it possible to tilt it like the factory did for the Porsche 4 cylinder? Also curious about your brake booster. Did you just remove it for test fitting, or will you have to come up with another solution for power brakes with this engine?

I was thinking a K-swap would be perfect and am interested to see how this goes. I'm interested to see what kind of clearance the hood has too. 200+ hp naturally aspirated is definitely nice with the possibility of much more with forced induction.

Thanks everyone. I removed the booster while test fitting the V6. I hope to retain the factory booster and brakes with the K24.  

Hood clearance will be tight but I think its going to clear with a work. The Honda engine leans 15degrees in the same direction as the factory Porsche engine does so that helps. Also people swap these engines into Miatas and "chamfer" the front edge of the valve cover for clearance.

I started making the bellhousing adapter yesterday. Started with half of an Acura RSX manual transmission. Hopefully more progress soon

Great project! So is it about an inch and a half higher than the Porsche mill? Any idea on the weight difference?
Came over from another forum just to post up in here, as I was struck with this idea when thinking about possible swaps. 250 NA HP would be a blast in a 944, and these motors are ubiquitous.

The 944 didn't have an engine in it when I got it so I don't know about the height difference. I believe the k24 weighs about 275lbs.

I designed a little adapter plate the past few days and cut a mock up plate. So far it's looking good. I'll think about it over the weekend and cut a real one next week. Here's a couple pictures to check it out.

It's pretty close to 5.5" and I measured the 944 bellhousing at a little over 6". So my adapter will be made from .5" plate. This should make for good pilot bearing/bushing engagement. We will see.
Hopefully the engine, bellhousing and clutch will all be sitting in the engine bay bolted together next weekend.

Thanks for checking it out

I always wondered what a f20c or f22c engine would be like in a 944. K24 will be nice too though... Goodluck!

I was able to get the flywheel and clutch mounted. And then the bellhousing and adapter plate. So far everything is looking pretty good. I had to clearance the "transmission tunnel" a little for the Acura slave cylinder. But it's bolted in there. I removed the oil pan and oil pump. The new oil pump is on the way. Then I'll start cross member and oil pan modifying. The stock oil pumps are huge so I'm pumping the much smaller RSX type S unit in. And here are a few pictures of the progress so far
