Engine slowpoke
Hi guys
I'm having trouble with my "new" D2 engine (td5). Last summer the original TD5 of my D2 broke down (oil chain came loose and went through the whole block). okay then, let's find a new TD5... After a while I found a Defender TD5 that had been in a small accident (purely cosmetic) and they we're selling all the parts. so I bought the TD5.. now, after installing the new engine I am REALLY disappointed in the performance (even in LR terms) my original enige used to bring me up to 160kph easily, the new one has a REALLY hard time to even reach 120 kph... it's so ridiculously slow... uphill it'll go 80kph.. not faster... it's really annoying if you get overtaken by a big freight truck while your giving it your absolute max... (td5 auto transmission btw)
any ideas on what could be the problem? is it possible it's restricted in some kind of way? because it came out of a def? or should it be remapped? I don't know if def's have other maps than disco's?
thanks in advance! cheers!

Not really a TD5 expert, its an engine that never came stateside.
Re-mapping is held in the engine ECU which a quick search shows may be the same for the defender. that being said, it doesn't sound like an ECU problem. you may have a restriction or low boost issue.

Any ideas on how to find & solve the problem? if it's not the ECU I'm expecting it to be quite an expensive fix?
Check for engine codes. until then, nothing really I can think of.

When you purchased the D90 were you able to look o we the engine / test run it? I’m not all that familiar with the td5 but with knowledge of turbo diesels are you sure the turbo is operating properly? Is it holding the correct boost / correctly functioning wastegate? Turbo’d diesels that have turbo issues are piggishly slow the way you describe.

We had one on an outing this summer that just sucked hard going up hills, literally down to 50 km on some of the long uphills here is what he posted on the issue and solution:
For those of you on the run and offered assistance will my black smoking gutless 300TDi, I thought I would share with you what the problem was...
After changing all filters, both fuel and air, checked all the hoses for leaks and interior delaminations I discovered the rod between the wastegate and the wastegate actuator had become unhooked. Upon further investigation, it would appear that the wastegate had become frozen, probably rusted up and because it wouldn't move the actuator rod had flipped off. So after two days of applying WD40 rust remover is loosened up and then reattaching the actuator rod with the wrong circlip it is all better, no smoke and lots of power. Just something new to be aware of.....

Yeah, the checking for delamination of the hoses is a good spot to check. See it often as diesel vehicles age. Inner hose becomes delaminated/separated and the loose rubber inside gets pulled down, blocking air flow to turbo.
