Came across this thread and thought I'd chime in-- I'm currently running a 4.135 from an 84 b2200 in a swap. I added a t3 turbo from an om617 mercedes and am pushing 15psi. I live in a rust belt state and broke the frame on my b2200, since it ran fine I didn't want to scrap the motor so I dropped it in a first gen rx7. I have about 9000 miles on it now running this much boost. I put about 40,000 on the engine in the truck while NA and so I can say the turbo is a fantastic addition. Highway cruising is much smoother and when you put your foot down at 55 its a very fast jump to 80. 0-60 is about 11 seconds and even on long uphill climbs at 70mph EGT's never pass 1100F. Haven't really had any issues yet, the truck broke at 185,000 miles so I'm right at 194,000 with no end in sight.

what rear end gear ratio are you using.. thanks.... thats a clean swap... thanks! Its the stock 3.9 lsd that came in this rx7, its just OK. I'd like to lower it as the top speed/redline is about 90mph. I can cruise pretty well at 70 but thats about as high as it wants to go for long rides. I was originally running the stock 5 speed gears where 5th was .82 so 80mph was right at 4,000 rpm (basically no highway) I upgraded to the gears out of an 87 base rx7 where the 5th gear is .69 and it made a massive difference. no one even knows its diesel

Hey Rusty,
Did you do any work to the injection pump to support the boost? Remember seeing your post on RX7 club a while back. I'm slowly working on re-engining a REPU with an S2, and your post was one of the reasons I decided to go with the Mazda diesel...

I'm slowly working on re-engining a REPU with an S2, and your post was one of the reasons I decided to go with the Mazda diesel... the only things i've done was max out the rack limiter and slightly advance the timing. Its about 1/8th of a turn from the point where it will run away but still drops to idle just fine. Under wot at any level of boost it will over fuel the engine and puff out a good bit of black so i have to watch where my foot is.

the first turbo I ever tried on my truck was a t3/t4 turbo and it didn't work very well at all. just like mentioned above all it did was make to much boost and almost little to no benefits in power gain or even torque for that matter. if your going to be using a Chinese turbo off eBay go with the td04-9 or 10. those are basically the same turbos the 10 is just liquid cooled. the tdo4-9 was used on the stock 2.3 turbo diesel ranger and if you look at the engine specs compared to ours, they are pretty close to the same so I believe that to be a proper sized turbo for the 2.2. I have ran the td04-9 for almost 30,000 miles and it never gave me any issues. I have it gated at 7 psi as well and to be completely honest anything above 7 psi on this engine makes absolutely no difference in power. I played with my fuel screw as well and with no wastegate all it did was make more boost(18psi) and poor black smoke, but no power increase over 7 psi and fuel screw turned to where there's very very minimum black smoke. I now currently have the td04-10 and it performs the same way as the 9 except my egts are running almost 300 degrees cooler Wayne, I bought a new td04-10 off Ebay upon advice from a fellow in Wisconsin who sells little propane injection kits. He said that after I get my motor sorted out, there's no point in doing a propane injector unless a turbo is on it to get it the O2 it'd need to be useful and utilize the propane. He suggested trying the turbo first and see what I think. So I've got the thing, and it was amazingly cheap (240.00) but it struck me how small it is and how small both the inlet and outlets are on the thing! I suppose I ought to have posted a pic of it, but I'm just curious about how the flow of exhaust is going to go when we're talking about going down from such a relatively large exhaust outlet on the 2.2 to this tiny inlet hole. I believe the manifold opening is 2" , but the inlet on the turbo is barely over an inch. Is that right?? I have a mechanic who specializes in exhaust systems (and has installed a lot of turbos in his day) ready to go on this project, but I'm anxious about these pipe sizes and how it works chocking down the flow pipes. Any comments? Thanks!

I never really paid much attention to the size of the outlet on the turbo compared to the stock exhaust piping. I chose to use the td04-10 because a td04-9 is what the stock 2.3 mitsubishi turbo diesel used and when you compare both of the engines specifications, there pretty close. I could be wrong on my logic I'm not sure but I assumed if the turbo was properly sized for the 2.3 mitsubishi turbo diesel it should be a good choice for the 2.2. I have read on here someone using the turbo of a Mercedes 300d, and one off of a European 2.2 diesel from overseas I believe as well. There's a YouTube video of a red diesel ranger with a awesome sounding turbo and I believe that is the one from the European 2.2 diesel.

I don't think there is any such thing as back from the dead on this forum. Just because the posts are old doesn't make them dead. It seems that everyone here is interested in whatever information is available.

Wayne83 - did you ever get a hall sensor installed in the IP? I am wondering about whether to save my spare 4d56 sensor for a future project or sell it to you! mind you one could be sourced from a japan application or some other application..

Well after running my inspection camera around inside the water jacket on the head of my low milage spare engine I have concluded that there is more than enough meat to do what I wanted and so it has begun. This is not for the faint of heart however this will dramatically improve the airflow through the engine. I have been researching lots of high performance European diesels and noted many differences between their heads and our heads. After making lots of careful measurements and comparisons of photos plus a few nights of deliberation I simply decided I'm going to take the plunge. I have lots of very successful experience with porting and modifying cylinder heads, so as long as I'm careful take my time use sharp Cutters and don't get in a hurry everything should be fine I will keep the photos coming as I slowly work away at this
