Today I dropped my injectors off at a local Diesel injection specialist that comes highly recommended, They were very nice chaps, very informative and called me back within 2 hours to suggest a route to take with them. Apparently they were sooo bad that just cleaning them could not be guaranteed to do the job. The flow was all uneven too! So they're are having new nozzles, cleaned up and being flow matched. Along with my port match this should make for a pleasant surprise when I get it back on the road!

Cheaper than a new set, which aren't guaranteed to be flow matched anyway. But not a lot cheaper. Still, £50 saving is a saving nonetheless. Flow matching made a big difference to matey's big power engine over on Pocuk so I'm expecting to be quite pleased.

When diesel specialists overhaul them they tend to use new ends from bosch or zexel etc.
They are OE or above OE standard and whne good guys shim them up correctly they work A LOT better than 'new' ones you can buy.
A new set of genuine injectors from a dealer is over £700 so it's not suprising that some of the brand new ones I have seen from ebay and some of the 4x4 companies actually bench test worse than used ones with 50k+ on them!

Infact, If anybody does need new injectors I would suggest buying a scrap/unknown set and sending them for recon rather than buying new cheap ones.

Yep, this is what he was saying to me. And he also said they only use Bosch or zexel if they can. So happy days After blowing my head I wanted something to sweeten the bad feeling of being an idiot! New glow plugs (she was getting smokey), port match and now uprated injectors should make it run lovely Bigger intercooler is going on soon, then I'll start measuring inlet and exhaust temps so I can see where to go with a bit more performance.

this flow matching assumes that the injector pump is also matched on all ports, little bit of wear on the swash plate, one of the pipe nipples a slight bit more restricted, slight differences in the plunger springs etc etc, all of a sudden you have spent a lot for little gains - if any

personally if i was looking for powergains i would be considering geoffs hydrogen system and playing with that

thing you also have to be aware of, the more tuned a motor is the more tweeking has to be done to keep it in tune, the less wear it takes before you need to spend lots on it to get the power back up, im a great believer in pure cc gives more useable gains than bhp

true but more cc = less mpg.
Although may well work out cheeper to buy more fuel than pay for upgrades!

This is all quite true. I'm not looking for massive gains. Been researching this since I first joined the OC. I can say now I know what can be done and how to do it. After the s/s exhaust and intercooler I'm going to monitor temps to see how agressive we can go with a remap. Probably end up leaving it there. MAYBE, not sure yet, I will go with a custom hi lift cam and machined pistons. 145bhp with a remap is already doable and safely. Breathing system sorted, and one or two of those other things I mentioned and we'll leave it at whatever it ends up at. !70+ maybe.

I made a deal with myself that if stu from Pocuk didn't want to sell his big power engine then I would get a second car as a pure green laning machine. Makes more sense for my dog as well. Despite saying he might sell he doesn't seem to want to part with his hard work. So I am currently in the planning stages for a big power build on an XJ Jeep. 4-500Bhp is no real issue on those 4litre straight 6 engines. And all off the shelf parts too. A brease compared to trying to tune a 4D56.

Oh and I am buying a hydrogen fuel cell as soooon as Geoff confirms the mpg results. Though mainly for economy reasons.

And yes, there is "no replacement for displacement." 4litre straight 6 with a 5.0litre stroker kit should about do it!

you know in years past i gone down the power mad road, mexico twin cam in an escort van, rs in an escort van, my mate shoehorned a jag 3.8 in his !!!!, mirafiori 2.0 in a lada niva, rover 3,0 in a lightwieght lr, 1275 tc into a std mini ( on drum brakes that was fun - not), helped the mate showhorn a range rover motor and box into a landrover - then added a holley 4 barrel and rigid hi lift cams - absolutely evil in a straight line

so with that in mind if your looking for a green lane beast why not buy a none running l200 and change the motor and the box

Needs to be 4 wheel drive. Still doable I agree. But it's what route to take. Do I get Vince (Bushwacker on here) from Elite 4x4 to do a Lexus conversion with a stack load of custom parts? It would be epic but I really want to do the work myself. At least most of it.

So I could do a V6 conversion to an L200. Heck my dad even has a Triton he's about to start breaking. I could rebuild the engine (done 200k) and wack it in a cheap 4work. Twin turbo it and that's 320Bhp.

Or I could do something totally outrageous and go for a Cummins or Chevy diesel complete with box. Again very custom but I need to figure out the 4x4 issue.

The Jeep makes more sense for my dog but not a big issue. Could just fit a cage for him in the tub. But Jeeps are cheap to buy and great cars to mod. I used to own one actually. And the mods can be priced in advance. But you raise a good point and I only just realised my dad has a V6 sitting there!!

when i used to do a bit of fitting on ford d series trucks we would never fit injectors before we had tested them ourself you would be surprised how many we had to send back

i bet the standard v6 is a low tuned workhorse thats got a lot of potential if your wallets not one for screaming `rape`

1000 Bhp Mike. No lies.

hello, i have a problem, i have fitted 195/65/16`s on my truck, giving the throttle pedal a dose of ` large` for some reason im leaving a rubber slick for about 150 yards, im also getting through more tyres per tankfull than i used to------ i`m assuming my tracking is out

I'm also going through gear boxes every 6 weeks!! Do they have a known fault?

i know that landy i put the 3.0 in used to pop drive shafts though i also managed to destroy the first motion shaft on one session

the v8 was a totally different beast, give you a story, ive borrowed it, sitting at the lights, chugga chugga , cabri escort pulls along side, the oblig blonde in the passenger seat, now hes pointed at the beastie and laughing with this tart, lights hit orange hes off, lights hit green im slipping the clutch, within half a mile hes well behind me, now theres another roundabout, oh shiiiiiit, brakes on, he screams past me, face is a picture, hes out n gone, caught him within a quarter mile, im up his arse and hes not impressed, he floors it, i floor it, chuga chuga now sounds like a shower of banshies in full song, hes getting smaller in the mirror, theres another roundabout coming up - oh fook ive got brake fade, dunno what speed we doing as the clocks about as usefull as an arse pocket in a bowler hat, gets about halfway around the roundabout when i clip the curb, landies now up on two wheels, im sure i can smell shit - lots of shit, somehow i get her down and back on the road, this muppit has now caught me and pulls over, jumps out and hes not impressed, obviously his phallic replacement has just been shown to be a flaccid replacement, hes shouting something at me, spit n flem all over the place, its not helped my me in a fit of laughter, by this stage of the game the blondes having trouble controlling herself as well, when i dropped it off, left a note on the seat, brakes shit, seem to have fade around mach2, needs stabilisers, think i may have annoyed some fella in a escort cabri

Haha excellent!

Just had the phone call that my injectors are done. They were indeed fitted with Zexel nozzles. Looking forward to putting it back together this weekend.
