Ive run standard unleaded and primium occasionally (bout every fourth tank) and havent experienced any problems/pinging. Thats a e88 head with round tops and a mild cam. I've also heard that lead replacement isnt that great, for the reasons stated above. Also be wary of independant suppliers and the quality of fuel they provide. They can import fuel from SE asia and (believe it or not) Kazakhstan, which both provide a lower quality fuel than our traditional suppliers. Maybe a saving a few cents at the pump mite equate to a lot more money in solving engine trouble down the track! :dead:

Guess that settles it. Prolly do the intake as well then... money money money. Ill tell ya what i think of it.

Ive seen pics of a few that have two stripes running up the middle, they look alright, but there was one i saw a pic of, had the stripe starting at the bonnet bulge, looked awesome! Cant for the life of me find the link tho. AHA! http://www.zcar.com/month/1999/02/ :tapemouth

Ive decided to get my headers ceramic coated. Both Jet-hot and HPC cost about the same. At the moment There is a lot of heat generated in the engine bay. I have a non-vented hood, a round top su's, and a rx-7 electric fuel pump. I still get a little vapour lock when its a warm day, say 25C+ and ive been driving for a fair while. Ill stop at lights or something and im there for a couple of minutes ill "chug" when a accelerate away. I dont have a heat shield, should I get one, or fabricate one as well as the ceramic coating? Anyone else get this prob with unwrapped headers? Cheers John

Can you see out of your rear view mirror with that speaker box in the back? Just wondering :cheeky:

I agree that you'll get the slowest car infront and the longest red light if the cars about to overheat. We got my friends pulsar home after 3 coolant stops. Though in hindsight we really should've left it where it was.

Gday, I just wanna run this past everyone to make sure my thinking is correct. Cylinder No5 doesnt make a difference when i pull the spark lead. when i check the plug its wet with fuel. I've checked plugs and leads and dizzy rotor. When its chugging away on 5 and i spray carb cleaner around the intake the miss goes away. So ive got a manifold leak. This only appeared out of the blue, I just finished wiring a rx7 fuel pump. I tested the pump on the car ran great. Wired it up so as to stop when engine dies. Then after that I started her up i started to get the got problem. I'm SURE the pump isnt the cause. Manifold gasket is prolly only 4-5 months old (The exhaust place is like "nah get no problems with these gaskets" when enquired about it when i got extractors fitted) So can a manifold leak prevent the firing of the cylinder? Can it just sorta happen suddenly like that? Is a 75 260Z Dome top Su's, 280zx dizzy and coil, mild cam, extractors with 2.25 exhaust. As of 3 weeks ago compression was an even 150 on all cylinders with throttle open. Thanks for the opinions everyone Luke

Read most of the main post, I cant even imagine how pissed i would be if i got ripped half the cash that those guys did! :dead:

oops sorry, i really should have re-read your post,

Gav240z - 79-83 Hilux 4x4, just make sure there s-12's to keep your solid disc. Currently saving pennies for this, does anyone else have any other combinations for up front? That wont cost the earth... Luke

Wouldnt you rather replace the jute with something that doesnt absorb water/moisture. As far as I see that is what a lot of the z's floorpan rust is from, horsehair staying wet for long periods of time. You could use a closed cell foam (XLPE or EVA), which will not absorb or let any water pass thru it. Its not as easy to use as the material or jute but it is lighter and a similar price to the jute (in Oz anyway). But lets hope well keep the moisture out of the car in the first place. FWIW 260Zed
