Daily diesel

[M.jenks]

Hi guys first time posting I have embarked on a journey to try and get an l series diesel to 200bhp......yep

So here's where I am up to mods
Custom stainless powerflow decat system
Sdi injectors
Reidy remap
180 brakes
Boost gauge
Maf switch
Front mounted cooler

Things to fit that are sat in garage
Gt2056s
Borg and beck clutch

I will chuck up some pics when I am home

You'll need more than SDI injectors to crack 200bhp.

They top out at around 170-180bhp purely from fuel flow.

I'm not sure what your clutch is rated to that you have sat on the shelf but it'll need to handle a fair bit over standard to crack your target.

(torque at 4500 rpm to crack 200bhp is ~230lbsft), and our engine is typically peaky even with bigger turbos fitted - so it'll need to handle ~270lbft; pending the mapping it might need to cope with more.

Good luck, there are not many L-series running 200 ponies....

You might want to consider an LSD of some shape - they do torque steer with 250lbsft if you are not sympathetic.

Hi and good luck.

Start getting into big money to get above 160 -180 bhp.

Will follow the build with interest.

200 bhp will need the power band moving northwards, not a bad thing as big torque numbers will kill the box.

head porting, common rail (1600bar+) a late gen vnt turbo with high exhaust flow and probably a bit of water meth.

Hi and welcome to the forum

I've no idea about tuning diesels.

Great to see another thread of a tuned diesel. Stick at it and it will be good fun

I was going to say, best ask Phil how to get to the "200" L Series Club

[stamford]

to the site and good luck with the project.

It doesn't "need" common rail or the water meth.....

and it has been done on previous gen VNT turbo's as well, but the GTB's certainly give it some extra overhead potential - once you work out how to get more fuel in there!

[Mark S]

it may not 'need' a clean burn - something that 1600bar plus rail has a chance at providing, but it will be a horrible smoky thing if it can't burn the fuel efficiently.

If its smoking like they often do when they get to the 160hp mark, then they will be suffering bore wash.
If you don't mind a smoky diesel with bore wash then you don't need a high pressure rail. But having that lovely film of oil on the cylinder walls washed away by excess fuel isn't smart.

You may not need a high flowing head and more cam, you could just (for example) whack on a monster turbo and crank it up to 50psi (don't think the motor would last long tho)
But if you use intelligence then you can get power with a clean burn, with minimal lag and without dumping in either huge amounts of fuel or silly boost levels.

But you could just drop in another diesel motor that had power out of the box in the first place.
Didn't Rover have a go with the Fiat JTD motors? - was that the 45 or 75?
