19J Turbo Diesel

So who on here is running a normal turbo diesel 2.5 aka the 19J? I'm thinking of getting one for my 90.... I'm really used to working on the 2.5na and the conversion would be dead easy as far as engine mounts, trans, fuel lines, etc... I think it just got a bad rep due to it's being on the market early and users not knowing how to maintian it and drive it properly. Any experence or opions?

Thanks.

I think you are right on about the bad rep these engines got. I think it is mainly due to the fact that the 200tdi was such a quantum leap ahead that the merits of the diesel turbo were lost in the translation. Greg Porter is running one in his camel 110 and seems very pleased with it. I have driven a couple and they are certainly a substantial improvement over the performance of the natural 2.5. The nice advantage is that they are alot cheaper than a tdi and as you point out you have developed confidence in working on the basic design. As a transitional motor they perhaps have a few shortcomings such as still relying on indirect injection that results in sluggish starting and smokey operation but regular maintenance appears to ensure longevity, or so I'm told :)

Andrew,

Just finnishing up a 300Tdi install. Have a template from M&D here. Can copy if interested.

I'd go 300 but the frame is all ready galvanized so I don't want to do any cutting and welding to it. The truck is running around with a 2.5na right now. The TD or 200 are my best options. I'm liking the TD for a number of reasons including the fact that I've got piles of 2.5na spares that will work with it. Still thinking about it... my 110 needs building before I mess around with the 90 again ;)

Talk to Stuart about the 2.5 DT conversion. A wizard mechanic did the 2.5 DT conversion on his truck.

It is an easy conversion, as conversions go, but do not be seduced into thinking it is with out challenge. In particular the exhaust for LH steering. You will save days of head scratching if you take pictures of Stuart's.

Remember to use the correct pistons if you bolt-on a turbo .... Also, Engine/trans location is critical and not what you would expect.

E mail me and I will put you in touch with Stuart.

How is the mounting of the 2.5TD different than the 2.5na in a 90? I though they where in exactly the same place.

Woops...I read 109 where you wrote 90 in your original post. Disregard my comments the conversion would be dead easy.

I like the turbo 2.5. It is simple and as you point out parts are easy. The 300 Tdi is the best if the budget and circumstance allow.

Here's a web site with some very interesting ideas.

Not the current project but this might be a good plan for the 1987 RR once the body work gets too far gone ;)

I also have been considering this option...I sent out a few emails to england, "Allard turbo" sugested one could intercool an old 2.5 with turbo, to improve performance above an normal 2.5 turbo and not hinder reliability (the sell a kit) and Turner Engineering mentioned that the later 2.5 n/a should handle a turbo just fine (they have a crankcase breather the early ones didn't, and an improved block) I forget what seriel # they metioned, drop them a line, they were very helpful.

I drove stuart's 109 2.5t and it kicked but on my 90. Who ever did that work is genious :wink:

Dixon Strachan from Rock Island Rovers is carrying Allisport who make and intercooler for the 2.5. I think it brings the HP up just a little over 100. I'm not sure of pricing but my guess is that it's in the $800's. Drastically improves cooling though, which is apparently one of those inherent 2.5 problems.

If you're just experimenting, this might be a good starting point for an Intercooler:

It's from a late '80s Dodge Daytona Shelby, costs about $60 from an auto wrecker or eBay. I'm installing one on my Peugeot TD conversion. It fits on the right side of the radiator almost like it was built for it originally .

I bought a dead 19J and Dixon shipped it in for me. Got around to playing with it this week to see what would be needed to rebuild it and it turns out I got it running. It is not running great, missing on one or two cyinders and smoky but I supect it is just the injectors and I have spares for that. Might take the head off to check the top end but I'll see what some good injectors do first then play with the timing at bit.

An intercooler seems like it might be a good idea to keep the engine alive longer. I'll think more about that once I've got the engine sorted. I should fine an exhaust temp gauge for it and a bost gauge.

All the research I did said that the weaknesses that gave that engine a bad rap were caused by lack of quality oil changes and the higher EGT's. People in the UK that have run intercoolers but not boosted the power and kept the temps down have claimed great reliability.
