Hi All, im dave from carrum downs. A mate who is a mechanic and I, who isnt a mechanic and with basic car knowledge. We installed a turbo into my 2.7ltr 2003 Toyota hilux 3RZN154R engine, ever since we got it going its been miss firing, back firing, running lean to sparkplug loaded with carbon. Everything but running right. Can anyone please help. My mate has told me the engine has changed the firing order to the downstroke would it change the engines firing order to its exhaust downstroke. I don't understand if or how this could be possible. We have tried everything almost. From fuel pressure regulators to about to install a distributor. To buying and about to install haltech 750. Im in need of some good advice to understand where we have gone wrong. It would be greatly appreciated.
✌️ Daveo
