82-GSL meets 2.2 Diesel- project thus far
 

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!

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

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.

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

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

wow your down in dayton. cool little gig.

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

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.

Running! couple week old video its almost road worthy now

Cool swap, I've been debating on a swap like this. I want to put the 4bt cummins turbo diesel engine in an fd. I assume ill have the same problem with the height for the hood to close but luckily they make plenty of ways around that with the fd's and the 4bt makes a decent bit of HP and an Insanr amount of torque but ill need a new trans and rear to handle it, so should be a L costly but I got money saved up for it.

I love cummins engines they last forever and i thought about looking into a 4bt swap before too but there is a very good reason I took that idea and tossed it in the trash- The 4bt has a weight of 745lbs!!!! Just the engine! the 12a i took out of mine weighed 310lbs (complete motor minus the flywheel) the 2.2 diesel i stuck in only weighs 390lbs (minus 45lb flywheel) and will still make 100hp 150ft/lbs so if you are willing to work with double that weight for 130hp /355ft/lbs have at it but I would advise looking into importing something else- there are many aluminum block turbo diesels in various things that you can get for far less than the cummins- they really are truck motors.

Budget build surge tank using Pvc a pvc float and a mercury switch on a lever to maintain half full (1 liter)
its the best way i've found to be able to switch back and forth from veggie oil to diesel without wearing out the veggie pump or clogging the filter because its only running when the surge tank is low instead of non-stop

The bigger question is how will you make a transmission designed to hold the measly torque of a 12a withstand the (in comparison) mountain of torque from a 302? T-5 my friend, makes everything easy cheese.

now with boost

just waiting on more IC pipe and glow plugs then i should have it on the road

I know, its not the most interesting swap as most people don't swap to a lower power motor but its getting 47mpg- I still have the 3.90 rear which puts the rpm's much higher than they need to be, i'll be swapping over to a mustang 8.8 with 3.27 soon. hopefully that will put me over 50mpg on the highway

I think this is an awesome idea. I don't know too much about that particular engine, but I would rock an efficient 1st gen as a DD if I could. I give you props for doing something original and economical.

How many miles have you put on the swap? Are you choosing the 8.8 rear just for the gearing availability? If you aren't building for power, that just seems like a lot of excess drive train weight, money, and work for 3 mpg, to me. Have you looked at other lighter options?

Keep up the good work!

Thanks, so far i've only driven about 250 as i'm still working the bugs out of everything and the 8.8 is readily available if you have a better swap let me know! I've never paid much attention to what drive trains are under cars so i dunno many of my options to swap- highway top speed is around 85mph and 65 is pretty much top speed for any cruising length right now, since i do a lot of highway driving i would really like under 3.4 rear which is why i thought the 8.8 with the 3.27 would be a good candidate but if you know of something lighter/cheaper/easy to find lmk!
my original goal was 100hp 150 ft/lbs and i don't think i'll ever go more than that so it doesn't need to be a beefy rear

I'm usually a purist. But, this is a great swap. Really neat stuff.

it must be amazing to get 50mpg in a car you absolutely love to drive.

Very nice and quiet, not what I was expecting. :)

It surprised me too I was expecting it to be very loud and have a ton of vibration instead its pretty quiet and very smooth

Oh for god sakes if no body will bite I will!

So................. is it, fast?........................or faster?'

No, it doesn't even matter, its such a cool swap

Seriously though, the concept of a diesel sports car makes me very tingly, finally some one to stand up to all those big turbo tdi Jettas and Golfs.

Hmmm... now that I have seen a b2200 turbo'd I think it would be an excellent swap into a 86-92 b-series extra cab for a daily driver and prob not lose any power since the b-2000 was only 80 hp brand new. Thankyou for giving me an idea for my next project if I ever get caught up with everything else.

thanks for the compliments!
when compared to the stock 12a it came with its faster, at least it feels that way, the way its driven really is a huge difference from the rotary as it pulls much harder at low rpm's.

i'm a member of a biodiesel co-op here and i'm the only member who drives something other than a Mercedes or VW so its going to be nice rubbing rwd in their faces, rwd that isn't 4200lbs :lol:

If you can find a b2200 diesel go for it! I now own two of this engine and both have yet to give me any issues. Perkins made a quality engine that accepted boost amazingly, and feels like it probably should have come this way from the factory, even with an inter-cooler their is hardly any lag. my next projects on it are a getting a tach and modifying the injection pump for boost fuel enrichment which from what i've read on the mazda truck forums seems like its pretty easy- I should have this thing out and touring the country by the end of summer!

Awesome swap!

Finding the truck isn't the problem there is one sitting at my dad's garage with a bad 5th gear (IIRC) and a rusty body. I have a S5 rx7 turbo laying here in my shop now all I need is something to use it in but I will be watching this thread for any info or links to anything usefull to the diesel.

wow sounds very nice when running, wouldnt expect it to be a diesel

FYI I read the ring and pinion from a diesel mazda b series pickup may bolt into a stock fb rear, perhaps other forum member could confirm this or let me know I'm mistaken. I read this on a v8 rx7 swap related website a while ago.

why would you want to swap that in? the rear in my 84 b2200 diesel is a 4.10 and the one in my fb is a 3.9, so i guess if I wanted the top speed to be 65 :lol: I've actually been thinking about sticking the gsl rear in my truck when i swap it out because the trucks final drive is so shitty on the highway

Never mind, for some odd reason I thought they were lower. Let that be a lesson, don't post based on info you read years ago, from a website you can't even remember.

This project has spent a lot of time in the garage but here it is up and running.

I lowered the engine 4 inches and changed the mounts to proper rubber.

Nice!

Super late response, but members have ran the Toyota 8" rear end with success. Not sure of the gearing options, but it's a eight savings over an 8.8 and a proven rear end.

Will you be DDing this anytime soon?

Love the hood art.

the toyota rears I've looked at were 4.10 to 4.55, the b2200 had a 4.4 rear so the 3.90 in my car isn't that bad. The top speed in the b2200 was 80-82 and the rx7 will do slightly over 90 (theoretically of course) I've been driving it around every weekend and working out the kinks before I can DD it, gets upper 30's all city driving so not bad.



Easily the lowest power swap ever.
