Default LC9 into a Porsche 944

I can't say as I've ventured into this part of the forum before...

I'm looking at swapping out the 4cyl in my 944 with a V8, specifically an LC9. Since I'm totally new to this engine, but swapping in general, I have a few questions.

Since it's originally a AFM/E85/Auto engine, is it possible to make it a non-AFM/E85/Manual?

My brain is all crazy right now and I'm not finding the answers that I need online. I don't see why it wouldn't work, but I've been wrong many times before.

Thanks!

Thanks for that, I got the whole dod/afm thing.

I was mostly wondering if I can delete that and keep the e85 and swap it to a manual. I might have to check out a truck forum, I suppose.

Picked up the LC9 today. Can't wait to start the tear down and cleaning it out. I have loads more research to do, but it's going to be fun building it.

Let me know how it goes. I am in the same spot, got a killer deal on a LC9 longblock and want to use it in my rx7.

Awesome! I'm on the same boat also, got the lc9 block that will be going into my e46, did you find out if you can make it manual? Maybe t56 with ls1 housing?

LC9s for everyone! haha

I haven't figured it out for sure, but I've drawn the conclusion that the T-56 will mate up to it. I just need figure out the bell housing thing. Not sure if the LS1 and LS2 bell housings are the same, but the LS2 seems to be the choice if they aren't.

Still looking around though.

You can use either. They are nearly identical but not entirely.

If you get an LS2 GTO bellhousing, you'll need a starter for a GTO. If you get an LS1 F-Body bellhousing, you'll need an F-Body starter.

It seems as if we're going in the right direction. The LC9 Block seems to be a god engine once the DOD/VVT is overcome.

This might help with the hardware side of things:
Summit Racing® Active Fuel Management Delete Combos 09-0026
http://www.summitracing.com/parts/cm...commendedparts

I can't offer expertise with doing the deletes and you still need to get the AFM portion of the ECU deactivated. Also, Black Bear Performance can do the AFM deactivation so an AFM motor always runs in V8.
Then there's the VVT too, which I don't know about. Maybe your cam vendor could elaborate.

That's what I've been coming to realize as well.

Good info, thanks. I already found a Dod/AFM delete kit for a nice price though.

You could also get a VVT cam from Texas Speed. I used the vvt-1 cam in a lifted 4x4 truck with big wheels and tires. It ran very strong for such a big truck with a stock stall. Good low end and strong top end. Was wondering how it would run in a swapped lighter vehicle.
Edit: actually it was a l9h 6.2L. But keeping the VVT is still a good option when tuned well. AFM has gotta go though.

I plan on running a full standalone ECU. So perhaps I can work around the VVT

I haven't quite decided what to do, computer wise, yet. I wanted to just get the OEM one and have it tuned, but it might just be easier to go with a custom one. We'll see when I start building it.
