you could look at going to a good proper diesel tuner to give it a tune up. Once its all back together,

When I had a 300tdi 110 rebuilt I had a full width intercooler, center silencer eliminator pipe and a properly ported and gas flowed head fitted, these all helped performance. Then I had Gwen Lewis "optimise" the fuel pump. The difference was night and day, it went much better, smoother and more powerful, torque was well up and the additional H.P. meant that it easily kept up with traffic and pulled like a train! If I had a 300tdi now I'd install new injectors, get a quality reconditioned/new injector pump and have it "optimised" by a proper professional tuner. Just because you're offended doesn't mean you're right. |

Kind of like the above. I recently had my engine rebuilt by Turners and went for the option of a gas-flowed head. I'd had success elsewhere with this many moons ago. The engine was probably fine, but at 230k I didn't want to start adding any performance mods onto it unless I could be a bit more confident the engine would take it and remain reliable.
In no particular order I also did/added: VNT from Bell; Full width intercooler from Allard; Donaldson air filter to help it breathe a bit better; Full bore Griffin s/s exhaust; The injectors had been renewed about a couple of years ago, so probably just 'breaking in' Finally I had the fuel pump tweaked by Electro-diesel in Exeter. I know Clayton / L110CDL had issues with his, but I've been really happy with that. My pump was apparently 15% down on standard when they first checked it, so they brought it back to stock and then did whatever tweaks they use. As a package, I've been just delighted. It is so much more driveable. I'm still happy to pootle along at 55-60mph but it's easier to keep it there, rather than lugging out of corners. I have an EGT fitted where the EGR valve would normally go. The alarm is set to 630', and I can pass that if I'm not paying attention - accelerating too hard, or up a hill. "Normally" it runs anywhere within the 300 - 500 zone. I also believe that the EG temps can drop significantly even in the few centimetres between my temp probe and the turbo blades, so I'm reasonably confident I'm running it in a sympathetic envelope. Next thing I'd like to consider is a further improvement on the air intake side/size. I understand IRB are working on a couple of options, one of which will preserve the stock locations. As I often say, Im no kind of expert, but by looking carefully at various threads over the years I came up with the list above as a sensible and useable combo. Donald 1994 Defender 300Tdi 110 SW - owned since 2002 - 230k miles and going strong (The 'rolling restoration' or tinkering thread: http://www.defender2.net/forum/topic58538.html ) 2000 Range Rover P38 4.0L V8 in the past.. RR classic - fitted with 200Tdi 1984 RR classic - V8 with ZF auto box 1993 Discovery 300Tdi not to mention the minis and the Type 2 VW camper... |

I'm happy with the performance of the 90 now, it goes as well as you'd expect a 300tdi to. The engine only has 60,000 miles on it so i'm expecting it to be in good condition. I'll wait until it's rebuilt and all the weight is bolted back on and then consider a few minor tweeks. I'm not looking for sports car performance, i'm quite happy for it to drive like a Defender + a little bit for good measure.

Given what you've just posted injector pump optimisation alone would give the most bang for your buck. Just because you're offended doesn't mean you're right.

I've put a 3'' exhaust on mine plus have a hybrid turbo, Airtech intercooler silicon hoses, boost pin and boost ring and Ashcroft ATB sitting in box's ready to fit, after that a dyno tune to get it all running nice, that should improve things
