Hi just wondering if anyone has ever try'd to convert the efi petrol motor to a diesel motor with turbo and running the efi system off the petrol on it ?

Never tried, but the EFI setup from a petrol motor won't suit a diesel as they are completely different motors.
No. Just no.
if one was to make an adapter plate to bolt the efi intake to the diesel head theorietically it could work or get a custom billet head with the intake schematics of the efi on the diesel head
How do you get the parameters/sensors from the TD engine that the EFI Computer requires?
Where do you get suitable electronic diesel injectors from?
I can't begine to imagine the cost of the engineering to get the manifold to fit
How would you program the ECU?
What possible engineering benefit is there in retaining the EFI intake manifold in the first place?
Petrol is injected into the cylinder at 40psi. Anyone know what diesel is injected at? I dont know exactly what the figure is but it's much higher than 40psi.
Up around 200 psi I think
Indirect diesels 1500psi +. Direct injection diesels 5000psi +. Common rail up to 45000psi.
Theres just so many things. Compression ratio (the head). Injecting diesel in an intake runner wont work at all. Diesel is injected at the top of compression stroke. Petrol is injected on the intake stroke.
Tb42 are chain driven cam. Timing cover totally different. No squirters. Pistons would not cope. No where to put injector pump. The list is endless.
Crack pressure of 1600 - 1800 psi ...
Marginaly different.
Would be far simpler to just swap engines.
Compression is different, but unsure if that's controlled by the head..
So possible different stroke length.
Is the firing order the same??
Indirect diesel injection is over 1000 Psi up to about 2000 PsiQuote:

Edit... (Sorry guys... didn't mean to replicate info... we were all typing together)
fule lines are different sizes to hey...peterol 6mm diesel 8mm?
Didn't know that??Quote:
