Has anybody tried to make our cars a desiel motor?? Alls I think you would neede is glow plugs, Pistons that make like a 20:1 comp ratio, a reinforced bottom end, and some arp head bolts with a reinforced head gasket. Just a thought.
no way in hell is this possible. aluminum is way too soft to deal with the extreme pressures that diesel motors produce.
:wtf:
Assuming you want it for fuel efficiency, it would be way more cost effective to go buy an old VW. A B-series engine would need way too much work for this to be possible.
stop smokin rock
I love the question! i agree with the aluminum problem, and i agree it is impossible. but GREAT question :werd:
they run compression that high? didnt know that. so whats an equivalent octane rating? guess thats why they boost. but how come no high end…
think of the possiblilities a semitruck that revs to 10k :shock: now put that motor in anything.
take out the diesel part. a 10 litre turbo with 20:1 compression. i know impossible but so is the rest of this thread.
The reason for no top end is that all their power is in torque. They need to pull a 40,000 lb load from a dead stop. And the turbo helps build revs so that they don’t bog down when changing gears.
Diesel fuel is like kerosene, so it needs high compression to ignite the mixture. Once the air is compressed, the fuel is added and combusts instanly.

I was just thinking. I wasn’t planning on doing it. Maybe sleeve the block. The only real thing other than that I was worried about was piston to valve clearence.
Hey Konflix, any particular reason you were thinking of converting? Or just something that popped in your head?
we a had a natural gas civic wagOvan when i was in school running 15:1. Dont know the specs on the block but 20:1 for aluminum seems insane
compression is the ONLY thing that ignites the fuel(no spark plugs)
the octane rating of gasoline reflects it’s ability to resist detonation…
whereas the CETANE rating of diesel fuel reflects it’s ability TO detonate…
bigtruck diesels have high end(between 500 to 600 HP at maybe 1900 RPM)
but TORQUE is WHERE IT’S AT for them(1600 to 2000 ft.lbs. at 1200 RPM)
It popped into my head when I was trying to finish building my new B18 last night. I just thought that it would be nice with a turbo and whatnot. I figured I would get flamed for the thought alot more that this, but I don’t care. I just wanted some honest opinions on it. Who knows, Maybe I’ll try it when I get outa College.
Just thing 180 ft lbs of tq @1200 rpms on our B18A’s. then the turbo and what not to make 400hp @6000 rpm’s, and maybe make a 9000 rpm desil motor. Insto presto, 500-700 hp. Another + is desiel fuel is $ .25 cheaper than 87 octain in my aera.
I’m actually getting a Golf TDI when I get out of school next year. Diesel rocks my world. It’s funny though, the car redlines at like 4500 RPMs. But I love everything about it. The sound, the way it drives… ohh… ohh…
Europe loves diesels. The US hasn’t really accepted them yet. VW seems to be the only company making a diesel powered car imported here.
Now a Gas/CNG car would be a good idea, since there is a whole lot less to doing it. And as a added bonus the state and federal gov’t give you sizeable tax rebates if you do convert. CNG should also be quite a bit cheaper.

So you think just because you switch to diesel you’ll have a powerband from 1200 rpm to 6000 or 9000 rpm. Right.
NJ state employees drive around my complex in CNG powered ford contours and escorts. CNG is cheaper but dont you need a place to get more gas?? Doesnt it have a very short range?? 250 miles to a fill?? If i am wrong please correct me
Are you planning on towing a cattle trailer or something? What the hell do you need that much low end for. That won’t get you anywhere faster.
And good luck getting an aluminum block diesel to 6000RPM. 
There’s no WAY you could get 400Hp from a 1.8L diesel. Even with a turbo. Honda has a diesel Civic in Europe, and it gets something like 180lb-ft, but only 70Hp or something? I can’t remember the exact numbers. But 0-60 time is way over 10 seconds. I think it’s closer to 12.
Is a flame REALLY necessary on such a thread. this whole thing is thero babble. but fun none the less. he did say “just think”. the glass is half full…right?
