hey guys, whats the go for converting a datto a12 engine to unleaded? i'm not super compitant when i comes to engines but i'm learning

The A12 already has hardened valve seats.

Just start using Unleaded. Some people like to use the additive if they are racing, but almost all sorts of road driving unleaded will be fine.

Reports of engines running slightly warmer on the freeway have been quoted, but nothing too bad.

also i'm sorry if i'm doing this in the wrong section, but can you get a 13b enginered in a 1200 ute? is it legal?

I think it would depend on where you lived.

If your in NSW I doubt it.

Having said that I have seen fj20 turbos engineered which supposedly isnt allowed.

How about an A10?

i dont think unleaded will harm your engine. i run regular unleaded in my A14 and it runs fine. i cant even notice a difference between regular and premium gas.

afaik you can also get hardened valves. tpn-show i was under the impression a10's and some early a12's had copper valve seats.

Na no damage, in South Africa we jus made the change from leaded to lead replacement petrol in jan this year. So any i phoned up a nissan dealer to find out what fuel i should use and he said i should have been using unleaded from a long time ago,

Dont even need t retard the timing.

thats good to know, on the 1200 i just bought the seller informed me that when he re-built the engine he set it up for unleaded, i'm assuming he means he's put in hardened valve seats

It could also mean that he retarded the timing a little to account for the difference between 91RON unleaded and 95RON leaded fuel...?
