Psycho can possibly help you...may be by the evening...

12k for mods? But you have only an engine, right? What are you planning, just a well-running engine, for display types, or a working, motive car?

aseem · 31st July 2005, 17:12

If you simply have engine, than u might want to mod it to run on vegetable oil or biodeisel. If you have a car and are looking for performance mods, than let us know.

I dont think that it will be safe for yuou to try and fabricate your own NOS kit. However a NOS kit in a diesel engine would not be of any help as it would lead to immediate detonation.

Rather suggest that you do a search on the web for propane fumigation for diesel's (works best with turbo diesels) this link should be able to get you going on your project:

However a note of caution "No welding near the LPG cylinder"

guys i hav a car.. i mean i have a 1500cc diesel engine in it.i wanted to do something with the engine.the problem is that i cant buy n just fit in the mods,,i have to fabricate it..so guys what can i do??
its my 1st time so i can afford to risk this cheap diesel engine car...i guy i can spend 20000 buks..

it's better to get ready kits from the market and fit it , fabricating any modifications may lead u to spending more .... and may bring down the performance of ur car , instead go in for ready kits like pete's kit .........

I think since he has to submit it for a project, Buying stuff off the shelf wont help him at all.
He needs to show that he's designed and made the stuff.

I suggest that you go on the net, there are various sites that will tell you how to fabricate a preformance exhaust with the specs for it.

Also try and use an innovative idea to inprove the intake, like a supercharger.
Easier to manage than a turbo i guess- basicalyy some form of forced induction.

and see what areas you can improve on in terms of timing and ignition.

i sugguest that you first get down all the power charecteristics and data for your Um-modded engine, then as you add each mmod, log down the various changes in data that you get.

What car do you have it in??
My guess is that you are prolly operating out of any amby.

Yes Diesel Kits are available but not advisable as psycho said they lead to detonation.

Welcome to LPG fumigation.

Hi Karizma, & Abhinav, I think dry nitrous systems for diesel engines ARE available from NOS. However, I'm not sure if you can get it within your budget. I also remember seeing a FifthGear video on YouTube where Vicky Butler Henderson tries out NOS on an old VW Golf diesel. She goes on to show that it improves performance significantly, by trying to overtake a truck within a fixed distance.

Also, is it possible to have detonation in a diesel engine ? I mean, would the added NO combust spontaneously even without the addition of diesel ? I thought NO just provided the oxygen, & you needed a fuel like gasoline, or diesel for ignition...

But AFAIK, Holley has some NOS kits for diesel engines which are readily available here in Mumbai.
