82-GSL meets 2.2 Diesel- project thus far
 
6 Attachment(s)
I run most of my vehicles on veggie oil, so I figure why not take a car I love to drive and put in an engine to match i'll end up with efficiency and hopefully not loose all drive ability. With a whole 61hp 89ft/lbs stock the engine is a dog right now but with a new turbo injection pump from Perkins along with new injectors and an s4 turbo i'm hoping for a final output more around 100-120hp

1982 rx7- 2.2 IDI Perkins out of a 84 diesel b2200 pick up-
only 86,000 miles were on the truck it came out of!

Attachment 715887
mazda is awesome when it comes to transmissions this is the truck bell housing matching
perfectly with a 12a trans rear half.

3/8th steel exhaust plate
Attachment 715890
s4 turbo with flanges made to soon mate it up to the diesel
dropped in

Intriguing idea, just wondering though, wouldn't the S4 turbo be too big for a 2.2 liter diesel. Considering the exhaust gases of a diesel are colder and slower moving then a regular gas/petrol engine of the same size.

it will spool it just fine, I had a 240d with a 300d turbo (same size as s4) and it spooled it just fine at 10psi its only .2l smaller

Figured I'd ask, you planning on porting the wastegate or going aftermarket?

Well that's certainly a different swap.

Gryffinwings 12-16-10 09:10 PM

Indeed it is different, but the hopeful power your wanting sounds low, I figure it might be a bit higher than that.

OneRotor 12-16-10 09:32 PM

I've been thinking about doing the twin turbo 2.0 diesel out of a euro-spec BMW 123d. 200hp and 300lb-ft. It's nice to see that someone else is doing a diesel swap. Cool project.

squeezing power out of an IDI diesel is difficult I figure i'll set the bar to something I think I can accomplish haha

where will you find one of these? I looked everywhere for engine options at one point I was looking into the Nissan RD28 or a Mazda RF engine but I couldn't find one on any jdm site for a reasonable price,

What the chocking point in the engine? It can't be that hard, I figure you'd get some pretty good torque figures as well considering it's a diesel.

Fleabay. You have to get them from junkyards in Europe. Not a cheap proposition, but I think that it'll be worth the hassle in the end.

what is the choking point? the difference between 300d NA and 300d turbo is 30hp at about 8psi and that is a huge change, I really think 100-120 is all that I will get max, my guess is it will actually be more like 85hp but I will dyno it to know.
now once I get this all together and working I will be taking it apart and doing a full ring job honing and all new gaskets+reseat all the valves it should be up to 100-120 then (but ft/lbs more around 150)

What I mean about choke point is, what is hold the engine back from making horse power stock? is it the ports? the compression ratio? Valves?

stock its an NA diesel that is what holds it back- it redlines at 4800rpm and only makes useable power from about 1600-4000rpm the port sizes should be fine to run 10psi easy anything over that and I would need to widen them, diesel is just a lot different than gas especially IDI- there is a reason its taken so long for lightweight small diesel engines to catch on here state side

progress, engine is mounted in- not pretty but functional, I have the fuel cell to mount and hook up and the turbo manifold to design and build still but if fired up earlier today and moved under its own power!

It looks like this engine uses mechanical fuel injection if I'm not mistaken. Any other planned modifications to the engine?

all diesel engines up till around 96 use mechanical fuel injection pumps and injectors, and yes I bought a rebuild kit from perkins with a boost prepped injection pump new larger injectors new pistons rings and rods as well as I will most likely be getting the head ported/ this is all once I get it running daily drivable

just startn 12-24-10 10:14 AM

wow your down in dayton. cool little gig.

Bwek 12-24-10 01:36 PM

Very very cool

awesome, makes me want to hurry up and get to work on putting my sd22 from an 81 datsun pickup in the 76 710 wagon that i've got laying around...

I heard those had like zero power and aren't very efficient either, have a different experience? that was on my list when I was searching for my engine but it seemed to have too many issues

Great swap man! Any updates? I was curious, you said Mazda is great with their transmissions? You're using the stock transmission with a different bellhousing? I am assuming stock rear end (GSL) ? If so, I am looking to swap a 302 into my GSL, is there any way I could get a bell housing to fit the 302 to the mazda trans. Where could I find something like that?

progress has slowed a bit due to a crappy school schedule but as of now it runs and drives. If i wasn't clear before the trans is from this car (82 stock gsl lsd rear) the bell housing is not. The diesel engine i am using came out of an 84 mazda b2200 pick up truck the bell housing off that matches the 12a trans, the body and gears of the 12a are the same as the b2200 just different bell housings. I have no idea whats good for the v8 but i hear Granny's Speed Shop is good for that stuff.

with my new manifold flanges on I need to figure out how to make the turbo mani... this should end up interesting I still have yet to figure out where to mount it. i am having issues figuring out exactly how i can use the stock radiator and still fit an intercooler too, I might have to go with a vmount style with an fd rad

12arotary. 01-30-11 02:39 PM

Update! turbo manifold has been finished as well as the exhaust and fuel system, unfortunately though the hood will not close the engine is just too tall so i'm either just going to cut a hole to make it fit or build/find a cowl hood if they even sell those for fb's.. I'm really not a fan of being the guy driving around with the engine coming out of my hood.

pics to come in the next few days

this is pretty cool. i cant wait to see it running.
