Re: unleaded conversion

I was looking at something like this:

Now I'm planning on using ULP friendly heads.

I'd use PULP- has the higher octane.

Re: unleaded conversion

Bronze guides and seats nothing else. Four years ago this cost me $410. It should be cheaper now.

If i wanted a motor to run 200,000 km, i wouln't use the addative, but if it is a fun car/weekend warrior, it would last for years. I used Moreys upper cyl lube for 20,000km over 4 years, and the valve seats were still like new. This was so i could run premium fuel.

Re: unleaded conversion

Yep, LRP almost all gone now.

Regular unleaded is absolute crap. Most performance cars should be OK an just premium, which is about 96 octane (same as LRP), but if it still pings with the timing where you like it, then the 98 octane fuels should fix it (BP ultimate, Shell Optimax etc).

If you take the heads off and drop them into the head shop its not too expensive. Shop around for prices!!!!!

Why not go for a full port and polish while they're off

Re: unleaded conversion

I wouldn't bother adding additive. Run PULP (95ron) not ULP (91-92ron). No sense wasting $ on Optimax/Synergy/BP ultimate (98ron).

Re: unleaded conversion

If it's premium it should be 95ron.
