Forums Forums Enthusiast Forums A - Z Autowirral More power from a diesel

My bro wants a few more bhp from the jeep, he doesn't wanna go down the turbo route as they crack in cold water and don't give even power.

We've thought about skimming the head and fitting nitrous, but is there any other way of squeezing some more power out of this? He doesn't really wanna be spending any more than £200 or so, depending on what's on offer.

supper chip?? maybe a tad over 200£ but power gains are massive on diesel cars

thing is it aint a turbo,and i think itll be mechanical injection and not ECU controlled,so god knows what u can do?NOS and butane are good ideas,not sure if skimming the head is good on diesels,or headwork at all for that matter.Maybe an engine swap?Fit a turbodiesel and itll have a lot more potential

No he doesn't want a turbo as they won't give power low-down and they crack in cold water. It is mechanical injection on this engine so a chip is out of the question. Skimming the head would raise compression hence raising torque, and nitrous works better on higher compression engines.

Any other ideas people?

The only way hes gonna get anything noticably extra from a diesel engine is do a turbo diesel transplant.

You cant adjust the fueling to your advantage on a diesel, nor can the timing be altered to give more performance and they are very restricted about what you can do - port and polish, and some head work, but the gains would be so little...

He could always try some thinners (With high % of either acetone or Tolulene) in the fuel, may give a few more gee gees, but if he wants more power a Turbo is the only way

Jim, i am facing the exact same problem with the Cruisewirral Transit Van

contradiction there jay.I think u shud go for a v6 petrol

And jimbo,think its best if u get another engine,even if its not a TD just get a bigger diesel engine,like the one in the tranny ATM.wot engine the jeep got atm?

Vauxhall 1.7, he'd want to stay with GM too as anything else would cost too much to fit. Already have an Opel Manta box, so it'd have to mate to that. There's complications with size too as it's in-line and the sump only just clears the axle on articulation

Jay, the TD would be easiest as you can already get transits with them. Otherwise I say red-top or V6

Cheers for the replies btw everyone, they're dead useful.

cossy powered lol, like the 1 of topgear

3.0 V6 for me.......

I have just bought an Ambulance as a donor vehicle, Click here to read up on the project.....

Manta rear box goes straight onto the GM engines, as does the Omega 'F25' ones (which have a wider ratio) and you can buy a shallow sump from SBD, or on ebay. 100 - 200 quid.
Get a 2.5 straight six from a Carlton! Less faffing about.

Miek, it already has - Opel manta 1800 box, shallow sump, induction kit, full straight through custom exhaust. Thanks for the ideas though, and he wants to stay diesel as they survive underwater with just the help of a snorkel.

really the only way to get good power out of a diesel is with a turbo. f@@k the n/a off an get a 1.7 turbo an get a good welder to fab a manifold to relocate the turbo to reduce it gettin pissed on, imho this would be the best option.

ah.
