944 Diesel conversion

Hello,

I'm Johan and come from the Netherlands.
I've always driven and tuned diesel engines so i thought it would be nice to put a diesel engine in my 944.
It's a 1984 NA 2.5 Porsche 944.

There is a lot of knowledge about these cars here, i would like to share my project.
I can use some help with some stuff

I put in a engine from a MK5 golf.
This is a 2.0 16v TDI engine and should do about 250 hp and big torque with big turbo and stuff.
Here some pics of my project so far:

I've bought a S2 for parts.
I want to put on the wider alu suspension.
And put on the Turbo/S2 nose.

I've bought a rollcage for the car:

...and turbo brakes:

I hope to get it back on the road in a few months..
I need to get it painted, and long ratio gearbox with can hold some torque..
I've planned to go to the track 11th of march, so i hope it will be ready
Hope you guys don't hate me for putting a diesel in a Porsche ;-)

Big concern was the oilpan and oilpump to fit because of the cross member and steering rack.
After reading here i've desided to drop the cross member 20 mm and lower the steering rack 30 mm on the cross member.
Looks like i can drill new holes in the member so wishbones will be on same location.
And correct bumpsteer with changing tie rod ends.
First i wanted to go with external oilpump and wetsump or complete drysump.
But this will cost to much and to much work.

Very nice swap. Do you know what exact specification alum you used to weld to the X-member? I've tested a couple types and 2000 series worked the best so far....
And a Big Welcome....Everyone here has chopped and modded these cars in some form or fashion.

To be honest i don't know..
I have a some sheet alu and alu TIG weld sticks and i usually use that stuff for all alu welding.
It welded up quite good.
I'll look if i can find the specs of the alu.

At least you put a 4 banger in with some cajones and better con-rod bearings I'm sure.

4 cil. 2.0 L 16 V TDI engine.
With strong rods, custom cams, big vnt turbo, bigger injectors and so on.
Will be 250 hp to start with and about 450 Nm torque.
Later will be about 300 hp and 500 Nm, but need to see how it runs with a lot of torque on the rear wheels..

Nice Project Johan

I've got my fit-up bell housing and cross member at work to do some mods for my TDI swap

You need more torque. I'm aiming for 650NM to the rear wheels in mine

Welcome, what an interesting project....

dutch people are weird..

only 944 to do 0.4l per 10km

Another very cool euro project…and not at all weird. The folks in the USA are not confronted with parts & service availability issues…add the eurozone's incredibly high fuel costs to the mix and the ridiculous registration costs/taxes due to certain modifications. And there's the challenge and uniqueness of the project. Not to mention what we all crave…the satisfaction when it is completed. Please keep us updated and good luck.

awesome idea. A highly efficient small displacement turbo with great fuel efficiency and amazing torque. You may need to work on the gearing to take advantage of the lower rpm range

remember, audi made FWD 016 trannies, also 01E... for diesels here in europe, so finding a suitable gearing shouldnt be any issue at all.

LOVE it...have often wondered the odds of this...

diesels are cool the local dragstrip here where live a guy races a 69 camaro with a 4 cyl cummings out of a fed ex box truck i mean to tell you this thing hauls butt.with the diesel he runs 7.80s in the 1/8 mile diesels are tourqe monsters.that would be a good motor to put in a 944 its relitivily small engine space wise and puts out v8 power.look forward to see it running

This looks like a very cool swap who says good things dont come in small packages. Keep us posted.

Interesting. I gotta keep an eye on this one.

Yes we are , but a diesel porsche??? Yes I know, the Porsche tractors and a Cayenne model also have diesel engines. Diesel = Not my thing.
However the pictures are impressive and would like to know how your project is progressing.
RPM/Gearbox??
