Anyone done it?
Thanks

Diesel Injectors
Whats the go with increasing your size of your injectors in a deisel engine?
Does it improve much?
Anyone done it?

I take it you mean injector nozzles.
I don't know what vehical you have but on my 80 series the nozzles are about $80 each, x 6 = $480
Personaly i think keeping the diesel engine at max manifactures specs would be the best way to go, just having bigger nozzles may = overfueling & more exhaust smoke.
I may be wrong.

GXL Turbo Diesel 80 series- 6" King springs + Rancho in-cab kit- 35" BFG Muds Twin ARB airlockers.
I'm not experienced with Toy motors. With some diesels increasing the injector size and pop pressure is done to improve performance.
Normally you increase fuel from the injector pump before increasing injector size, but only after increasing the air and monitoring the EGT (exhaust gas temperature).
Diesels need to run lean (the leaner the better) to keep temperatures down (this is opposite to petrol engines).
More power comes from burning more fuel, but if you don't increase the air (boost pressure, larger free flow exhaust system, improved intake system and intercooler) the higher temperatures will probably destroy your motor. Some Cummins motors now have steel crown pistons because of the high temps.
I think (may be wrong) stock Toy motors run too high a compression ratio to do a lot with them.
