1984 300td (drift project) - Theturbodave - 05-15-2012
Hello I'm Turbodave.
I saw this 1984 300td in a impound lot earlier this year. It didn't run, it didn't have a back window and busted ignition cylinder. Well let's just say i got the car because i was the only one who would bid on it.
Some may not like what I have done. But keep in mind I got it to race,drift whatever.
I didn't buy this car to restore it or fix it up it was bought to use for drifting first and every thing else second. I know there are some different parts that could be used for this project but i like to use what I have on hand to keep cost down.
Here is what I started with.
RE: 1984 300td (drift project) - Theturbodave - 05-15-2012
Sorry pics not in order.
I did a base line run on dyno every thing stock it did have a exhaust leak at flex pipe but not bad. It did 81.5 hp and 159 tq automatic to the wheels bone stock w/factory exhaust and air cleaner box.
I then removed exhaust from down pipe back, put 3"cold air intake to k&n filter, deleted egr, adjusted throttle linkage to make sure going wot and deleted all vacuum lines from injector pump it did 101 hp and 197 tq to the tire.
I remove bumpers and changed to some wheels I had. I cut factory coil springs to lower it.(I changed this out later)
I picked up a extra injector pump for $200 at a junk yard.
I'm doing a turbo upgrade (I find out later this turbo has wayyyyy to much lag) he351 Dodge Cummings turbo(thanks led-panzer for correct number and yr).
While i was doing the turbo upgrade i did some intake manifold upgrading also.
Time for more dyno runs before getting to the fuel system.

RE: 1984 300td (drift project) - led-panzer - 05-16-2012
That holset is an HE351, comes on the 04.5 to 07 cummins. Same compressor as an HX40.
What turbos do you use for your compound setup?
RE: 1984 300td (drift project) - iheartboost - 05-16-2012
wow! thats awesome.
RE: 1984 300td (drift project) - Theturbodave - 05-16-2012
I'm trying to remember the order i did everything ???. I think I did the rack limiter delete, increased the rpm limit speed and max the what was it called alda (more fuel at take off). I can tell you this every injector pump is different (like someone on this form said the adjustment need to be done in small fine adjustment and telling someone to turn this 2turns doesn't mean it will work on all pumps, it is a 50 50.) I did one adjustment at a time and them tryed it out first before going to another.
THE BAD NEWS (like you could have problems when you are learning/messing with the injector pump's internal parts)
I put the the pump back on hook everything up hit the starter it cranked right up and instantly went to 5800rpm I snatched the fuel supply line to injector pump off (still at 5800rpm)and then went to snatch cold air intake pipe off wouldn't come off ,grabbed a nut drive to loosen clamp and stuck my magnetic bolt holder on inlet of turbo and it died. I would say atleast a 1 to 2 min at 5800. I'm looking around for what went wrong what the hell did I do wrong. Then I see it ,no spring on bottom throttle arm and linkage was bound up.
So I fixed that went to crank it sounds like no compression on atleast two cylinders. I'm at this point calling myself a dumba## and thinking it bent the valves from revving so high for that long. I just had to walk away for a while I pulled the valve cover to check for bent valves. I pulled cover and checked valve lash haaaa there is none, All of the lash adjusters had unscrewed hold almost all the valves open. I adjusted every one back to spec and started the wagon it runs better now than when I got it.
At this point I love this car.
This time on the dyno it has way to much fuel for factory turbo it made 125hp and 240tq waste gate held shut ?on how much boost , it looses power and tq bad on top end 4000rpm still rolling smoke. I'm turning it to 5700rpms. At this point I know it needs more airflow.
I put holset turbo on and i did intake manifold and just ran a 4" downpipe with no exhaust. This turbo is to big for a auto can't brake boost it and it creeps to 22psi. Dyno 145hp and 220tq hits 15psi at like 4600 rpm and 22 at 5600 and it hasn't got enought fuel from around 3600 and up. I know I need some fuel on the mid to top end and a little bit smaller turbo.
I have gone of the deep end now UPGRADES.
I got another set of injectors from junk yark and ordered new injector nozzles ( I think they were dnosd303 or 306) I will look for my paper work and get number. I put a 320lph (aftermarket mustang) fuel pump on deleted factory fuel pressure regulator and mechanical pump and put a adjustable fuel regulator w/ boost/vac line on and ran new fuel lines. I also did DV mod not full cut but milled lip to a tapper. Now this thing got some fuel.
I think the key is getting rid of factory pump and regulator. You can now run what ever fuel pressure you want and it increases fuel pressure with the boost level. I run 25/28 psi at idle and at 18 psi it makes 50psi.
I had a stage 2 turbo form a Buick Grand National that I had upgraded for 62-1 turbo and know it was a good one but it had the 3bolt mounting flange and .90 a/r exhaust. I milled a Garrett T3 exhaust housing with a .60 a/r to fit the 58mm exducer wheel and tappered mill the inlet houseing to fit a 3 1/2 inlet pipe. I tig welded a 3" v-band on exhaust housing for the down pipe. I drilled out the exhaust manifold to weld a 38mm wastegate. I ran wastegate dump back into the down pipe. I ran 3" down to 4" exhaust all the way out the back by rear axle.
Lets just say this turbo is the sh#t it will foot brake to what ever waste gate is. I set waste gate at 18psi. This turbo is bad as#. Instant boost you don't have to brake boost to spin the tires just nail it and instant cotton rolling from the tire 1st and 2nd gear Tries to blow through 3rd gear.
I will upload more pictures one these mods.
RE: 1984 300td (drift project) - Theturbodave - 05-16-2012
WERE DO YOU PUT AN INTERCOOLER ON THESE CARS. There is no room anywere and I'm not mounting outside the body(just not me).
I was thinking I could build an intercooler that looks like the grill and remove the factory one, but I don't think it will look right not being on the hood when you open it. I also thought of moving radiator to rear floor board and put intercooler were radiator was.
any help would be COOL.
RE: 1984 300td (drift project) - DeliveryValve - 05-17-2012
First off, welcome to this forum. I saw your craigslist ad and link to your build, and was hoping to get more details on this wagon. Thanks for sharing your info!
The best fitting intercooler are the Air/Water type. If your not using your SLS pump, then you can remove the reservoir and put in an A/W intercooler in that area like this.
Then put the intercooler radiator in front of the engine's radiator.
.
RE: 1984 300td (drift project) - Hercules - 05-17-2012
Looking real good! Don"t think there would be enough air flow if radiator on rear floor board,plus mud,dirt,road stuff. There are posts on here what others
have done for intercooler,usually small units if inside. Water inj.is another option,pre-turbo should work well,cools incoming air plus allows air in turbo to be further compressed . Volvo states the compressor wheel should last 200 thousand miles.
Question: What is the Adj. fuel regulator w/boost/vac line from?

Incorrect. Those are not the stock tires, and what hes doing with this car is not supported by the mercedes factory, plus, drifting will throw around his set of golf clubs and bottle of Perrier-Jouet with crystal stemware. For shame.

RE: 1984 300td (drift project) - erling66 - 05-18-2012
Can someone please explain to me why cut DV's gives more HP? The elements are pushing the volume they are pushing so why does DV's has anything to do with that? Are the stock ones a restriction? I don't get it, maybe my brain is not working today?

Well, the end-of-cycle is created by the collar below the seat on the delivery valve by cutting this you allow more fuel to seep by creating higher pressures in the injector lines causing more fuel to be delivered. but it's not so precise with the injectors opening at there pop pressure earlier beause of more fuel at higher pressures in the injector lines and lasting longer then the normal injection cycle.
Basicly, its a ghetto way of getting more fuel. It idles like shit, doesn't really have even power till about 15psi, touchy throttle, and has really high EGT's. It's defiantly like playing with fire. There was one guy that didn't remove the collar completely and said egts we're below the melting stuff zone, but still has the other issues. DieselMenkin says there is no way to overcome these issues thats why everyone 'recommends' you get a pump modified with bigger elements for more power.
RE: 1984 300td (drift project) - Theturbodave - 05-18-2012
Your right on poor man's fuel. If you have the money do it the right way get your pump and injectors done by a good injector pump shop.
I like to find other ways around cost. The cut Dv's are not for everyone. I did them three different ways, cut small knotchs, tapper cut and full cut. The tapper cut were the best all around with a good single turbo.
The problem is idle and egt vs boost with the cut Dv's (I have seen and read your posts on this and wanted to see what i could do with it).
If you have to much fuel you just add boost. Egts and boost(airflow) work together if you understand it that way you can make alot of power.
Example; alot of black smoke=high egt's = you need more boost or remove some fuel for that boost level.
A perfect setup is at your max boost level you have a slight black smoke out the pipe. You should be able to see through it easly. If you are rollin coal you egt are going to rise quickly.
I have spent alot of time on the dyno to see what does what.
This is why i did the compound setup. You will not be able to do cut Dv's if you can't supply the boost for the entire rpm range. The egt's are just to high. My set up does instant 12psi when you just touch the throttle in gear and then at 2200 is 28psi by 2800 its at 35psi. That's how it works
You can't get a single to work that way. Small turbo good at the bottom end, okay in mid, nothing on top end. Med frame turbo okay bottom, good mid , okay top. Big turbo never going to happen ,bottom end nothing ,mid range getting there, top end okay egt's are out there.
The idle( i have almost got the fixed w/some vacuum valves and fuel pressure control). I don't have it perfect yet put almost. When I do this forum will be the first to know.

Fuuuuuuuuuuuuu................... That's a LOT of boost!!!!! I barely get 12psi after a while at full throttle, you get it instantly with just a touch!!! Man am I jealous right now lol
RE: 1984 300td (drift project) - erling66 - 05-19-2012
Thank you guys for info, I get it now
I can see that there is a ca 1mm spacing between the collar and the seat. the collar is obviously needed for the idle but if it could be moved closer to the seat, less fuel will be returned by the DV.
I have a theory how to do this
You need a good lathe. Cut the collar and make a new one where the seat is and make a new seat on top of it. there should be metal enough below the spring seat. Maybe you need to take some of the spring seat but it should be strong enough.It would be very interesting to hear if someone try this. My lathe is from 1930 and not exactly what you would call precise
Keep up the good work Dave, I really respect guys that gets power without just buying expensive parts.
Do you have some good photos of your compound set up?
RE: 1984 300td (drift project) - Theturbodave - 05-19-2012
I just slapped the compound setup together in two days to see if it would even work. Now that i know it does I'm going to build a nice refined system alittle more compact.

I will post pictures and vids I have(I think i have vids of every stage on dyno). I just have alot of work I'm doing with twin turbo's kits on the 2010 Camaro's right now. I'll try get something uploaded at work (I can't upload them from my ipad).
RE: 1984 300td (drift project) - Hotrodbenz - 05-23-2012
What waste gates are u using would the stock ones not work? My h1c is not waste gated but I'm very interested in your piping if you are rebuilding it: )

Maybe if you crank up the line pressure, and make the shifts earth shatteringly stiff.

I've had two fresh autos go out at stock horsepower. One was rebuilt with paperwork. The other was brand new OEM mercedes, not rebuilt.
I don't see 250hp being a reality, unless you start dicking with line pressure and or adding in extra clutches when being rebuilt.

RE: 1984 300td (drift project) - Theturbodave - 09-27-2015
Sorry it's been awhile. I had sold my wagon awhile bk. I have missed the wagon ever since.
Well I just picked up a new one a 1985 300td wagon that has a spare motor and I had already picked up a motor to start building a new compound turbo setup on and I'm using a R154 transmission with an adapter I'm building.
I want to see how much you can make without it coming apart and still be usable on street/track.
On this one I will do a cleaner setup (old one was just kinda thrown together)
I will also keep you updated on were / what I'm doing to make it all work.
RE: 1984 300td (drift project) - Bigpanda16 - 02-20-2016
Dave, you should do an om603 or 606 and forget about the old 617. That would be more your style with better volumetric efficiency and power potential
