I have this small 2.2 litre Yanmar diesel engine, it came off my reefer unit and is almost new but CA air resourse board thinks we are made of gold and we should be replacing our engine every 7 years so I want to get good use out of it.
I want to put it in a car or a small pickup or even a Sammy, but with no Turbo I suspect I will not be very happy with it.
I still have to figure out what tranny to put behind it, thinking a 700R4 should do the trick.
Now the Turbo shouldn't be to hard to mount at the end of the manifold, but I have no idea for sizing.
I know the engine can turn 3000RPM and has about 90lbs of tq.
I want a bit more but have no idea what to use, thinking a wastegated setup could get more off the line and then keep the pressure regulated thru the wastegate throughout the powerband?
I know a smaller impeller works faster, but how much?
ANy help appreciated.
I was thinking to strap it on a dyno first and see what I have to work with then start a test chart.
Also should I figure out the tranny first and then start working off the output on the tranny or work from the flywheel numbers?

I dont know about the engine but the tranny I would think a 200r4 would suffice.

A 200R4 is a great tranny and unfortunately I want a 4x4 so 700R4 would be the ticket.
If I could get one of those newer 5 or 6 speed tranny's to work with no electronics I would too.
 
Two things to consider, what kind of comp ratio does the engine have now, and can fueling be increased. If the comp ratio is really high now, like a lot of na diesels are, will the head gasket and bolts among other things be able to handle boost. As far as the fueling goes, can the injection pump be "turned up" and are there options for injectors or would you need to find someone who could mod your existing ones.
I bring up these two points because I have a 4B engine that I picked up and compared to the BT's these have a lot more comp and a lot less fueling, so at least for me it's not as simple as just throwing a turbo on it and calling it good.
 
What your thinking of is not a waste gate. Its a variable inlet diameter. Lots of newer turbo cars are using them and they basically restrict the exhaust at lower rpms causing the turbine to spool easier from increased pressure. Its like dynamically changing your turbo throughout the power band what whatever is optimal at that RPM.

They are mostly computer controlled but when I was planning my OM617 s10 project I did see some guys adapting them to vacuum/throttle operated.

As said the engine basics are a must. The 2004r is an excellent trans for a lightweight vehicle. Just remember if you do a samurai it has a divorced case anyway so the 2wd part is pretty void.
 
On diesel engines they are called variable geometry turbochargers. VGT VNT VVT are all synonyms for the same. in one form or another, they all mechanically change the volume of the turbine housing. dynamically changing the turbo A/R based on current operating conditions. Honestly I wouldn't even bother with the effort to rig one up on what your looking at doing iceman.

you can probably rob the turbo off a 2.x liter john Deere engine. I've worked on a couple J/D gensets with little bangers in them. that turbo would be just your ticket, they are small turbos, but just what that little engine needs. or you could really easily get a K24 turbo off a VW 1.6L diesel. its actually bigger than the J/D turbo.

Speaking of "little" turbos, I was just looking at the baby S1 mounted On the diesel engine on a concrete slab saw. Not sure of the manufacturer of the engine, but , it has to be one of the smaller turbos I have seen.

ya this JD turbo I saw, was hands down the smallest turbo I've seen actually working. the size of your fist plus a little. unreal. way smaller than the K14 K24 turbos on the old mechanical VW 1.6L & 1.9L diesels. I should have taken a pic. me the pic whore not taking a pic. musta been actually working or something :doah:

Yanmar 4 banger out of a TK unit ?

Yep :D
I think was thinking what demon said but just wanted some opinions.
And as far as constatntly changing A/R, no it wasn't what I was thinking, I do know how wastegated tubos are and they do exactly what I said they do, they are smaller, so they spool earlier then when they develop too much pressure the wastegate opens up to realease pressure and you can still go higher RPM.
I wasn't talking about too fancy but trying to get power in lower RPM instead of starting to boost at 3000RPM which is where my engine stops revving.:whistle:
So Wasted... what do you think?
Do you know any specs like compression ratio or possibility to adjust fuel?
I know that mine is computer controled but not the injection, just the throttle and start so once the engine is sepreated from the Smart reefer controls it's just a mechanically injected diesel, and I have the Magnum which is the biggest engine in all TK.
 
I worked TK for about 15 years during the time they installed Isuzu C201's and OM636 Mercedes in the units... TK was just starting to come out with the Yanmar's when I got out of that line of work...

I do know Yanmar had some issues with pistons cracking in half along the wrist pin line....In fact I changed a TON of them under new warranty....
The Yanmars were in small straight truck reefers 2 - 3 cylinder engines.

As far as the boost, I don't know if the engine is up to it... the injection pump is set up for a pretty linear load in a TK...idle or 2850 RPM... with a designed constant load.

not sure if the pump would deliver the fuel needed at varing degrees of load
if used in a vehicle....

I used to play with the C201 engines on the dyno.. changing the pop pressure of the injectors and adjusting the pump timing.... I could get about 8 HP more than the 28 HP the factory rated them at...

My brother still works for TK...I guess I could rattle his cage and see if he has any ideas or thoughts about the yanmars....I'll keep you posted..

Yeah these 2.2 engines are a long ways from the old 28-45 hp engines they had before. This engine is the biggest at 90lbs tq and 110 hp it's a 4 cylinder inline four.
But yeah ask him and let me know if you could.:thumb:
Worst case if I can't turbo it, I can make a lightweight buggy for off road only, build it from tube and sammy axles for really tight trails.:whistle:
