2.5 NAD out 200tdi in = Rocket

Took my 90 out for the first test drive since installing my 200tdi and I am absolutely amazed at the power difference between the 200TDI and the 2.5 NA

Still have a big grin on my face ½ an hour later

I took it around the neighborhood where we have some steep hills, with the old motor I would have to be in 2nd and it would puff a big black cloud and struggle the entire way with the new motor I started out in 2nd, shifted to 3rd and was accelerating up the entire hill with little to no smoke.

Has to be the best modification I have done to my 90 so far

Lame I know but I had to share with someone since my wife just rolled her eyes at me and said “that’s nice”

I had and got the same reaction. I was so pumped and everyone was like BFD! It must be a Land Rover and a diesel thing.

Side note, just ordered a diesel for my Mazda pickup I like my 200 so much.

I honestly think my 2.5TD is SLOWER than a NAD- never thought it possible. Can't wait for a 200/300/Isuzu upgrade- thanks for the shot of inspiration, and glad she's peppy.
Hey Tom- put a 200 in the Mazda. That would be a first, a LR motor transplant to some other marque :-) Misery loves company....

Congrats, and welcome to the Tdi club I was going to say something when you posted about it in another thread. Doug he should have a 1.4, 1.6 was only in the 110's. Ashcroft has good information on how to determine the ratio based on the serial # (and how to find the serial #).

My 1985 90 had a 1.6, my 200 came with a 1.4

I'd go 200tdi in the Mazda, but I'm looking for plug and play(Haha)

I know you told me a bunch of time Doug, I just had to experience the 2.5 NA for a little bit so I could truly appreciate the TDI… How will we know joy if we have not suffered

I just assumed that it had a 1.6 in it but will crawl under it and have a look, I am planning to swap out the transfer case and thinking about a 1.4 but still on the fence between the 1.4 and 1.2

1.2 cheap as chips but not sure how it would go with 255/85 and stock diffs here in Colorado
1.4 almost like having 4.11 gears in the diff in hi range, might push the tires better and build boost lower

Mark,
Next big thing to make me grin from ear to ear will be the new doors hint hint

Dave,
now there are 2 stratos blue 90" TDI's

Tom,
You going with the 2.8 power stroke that was in the ford rangers or a mazda motor?

Chance,
I will try to bring it to the next happy hour if possibe

Tom, interesting that yours had a 1.6. I was under the impression that all the early 2.25 trucks were 1.6. The more I read I saw that the 90's were supposed to be 1.4. Mine was not marked with the ratio like the newer cases are, and the serial number was on the left side near the bottom. I had to use a mirror to read it. I kept a record of the #'s, mine was 13D023892A. And your engine was a 2.5 petrol? I would think if a 2.25 came with 1.4 then so would a 2.5. Perhaps it was a market thing as yours was a Saudi spec or something yeah? With AC?



Also...Dave...I *think* mine is Marine Blue...i.e. a Series LR color it appears to have been resprayed at some point.

Ren Ching- Daves truck is/was a 2.5 natural diesel not petrol.
Dale I think you are right about your TD being slower than a natural. I felt like Fred Flintstone driving it on the interstate.

I forget now why I thought my old T/C was a 1.6, because your right Dave, it wasn't clearly marked like my 1.4. I think I checked the serial number somewhere.
It was an odd setup , Funky desert brown color, A/C, 2.5 petrol

The Mazda is a 1993, before Ford. I bought a 1988 for parts, tranny and engine mounts and will be putting in a Mitsubishi 4D56 2.5 TD (the 1988 had a Mitsubishi Gas motor so thats why I needed the mounts and tranny/t/c

The driving force behind the swap was the kids who did the 90 were fiending to do another diesel swap.

Dave, if it helps, I'm a total flat lander and the 1.4 is a bit low for me, but not enough that I would feel the need to go to a 1.2.

Just checked the SN on the transfer case and it is a 13D

13D = 1.410 LT 230R

http://www.ashcroft-transmissions.co.uk/part_8.html#pa1

I just assumed all 2.25 and 2.5 NAD came with the 1.6 but since I already have the 1.4 that will same me some $$$ and effort

Thanks!

1.6 t. cases were only on 110s. All 90s came with 1.4s.

I find the 1.2 better than the 1.4 all around. It puts the engine in a better part of the powerband on the highway. I run 34s.

It may depend what gearbox that you have as to the choice. What gearbox do you have??

I heard that.

The 200 Tdi compared to a 2.25 in my 90 was such a difference. I'm getting 25 on for my combined fuel 11 miles city 16 highway on my daily drive. Couldn't be happier. Now I can pass in a timely manner... first gear is about as useful as a girl in dodgeball though :D.

If you have a 1.2, first becomes a used gear.

Girls have a lot of uses in dodgeball.

I have an early lt77 with the low 1st gear.

From what I understand it might not be up to the task behind the 200tdi so I have been looking at the new short r380 that acshcroft is offering.

Actually that depends on the suffix. What suffix? If it is G, you will be fine as they are as strong as the LT77S that came with the engines.

I have one as well and the gearing works well with the 1.2. The R380 might be a bit tall for the 1.2, not sure.
