LLave Posted August 1, 2006 Share Posted August 1, 2006 Well I finally got my first Z. It has an F54 block with a P90 head. Right now I am working on gettign the motor to run good. Where you you suggest I start? Thanks, Mike Quote Link to comment Share on other sites More sharing options...
b__sosick Posted August 1, 2006 Share Posted August 1, 2006 hi! welcome to hybridz!!!!!! start by replacing the plugs and wires. flushing and replacing the coolant. changing the oil. do you know how to tune carbs? should probably drain the gas tank if it's been sitting for a while and replace the fuel filter. again. welcome to hybridz! this place is a wealth of knowledge and the only thing you need!

2126 Posted August 1, 2006 Share Posted August 1, 2006 Buying a shop manual is a good place to start. At least then you will have a reference to go by. After you change the oil/filter and remove the plugs, you may want to do a compression and leak-down test....it will give you an idea of the condition of the engine internals. Then follow b_sosick's recommendations. Congrates on your first Z!!! Quote Link to comment Share on other sites More sharing options...
LLave Posted August 1, 2006 Author Share Posted August 1, 2006 Thanks guys, I dont have any idea how to tune the SU's. I read about using light weight oil (or atf) in the carbs. I was thinking about ordering the SU video from ztherapy. Also I have no air cleaner assembly, what do you guys recomend? I was thinking about these: http://knfilters.com/search/product.aspx?Prod=56-1410 How do I tell if I have the 70-72 or 73-74 carbs?

Forrest Posted August 2, 2006 Share Posted August 2, 2006 Definitely buy an FSM. That's interesting that it has a turbo head and (possibly) block...did the previous owner tell you why? Did he shave the head or maybe put it on a flattop F54? Quote Link to comment Share on other sites More sharing options...
LLave Posted August 2, 2006 Author Share Posted August 2, 2006 FSM? Factory Service Manual, right? Is the F54 similar enough to the L24 to make the manual worth while for the motor? Yeah I was thinking if it is the dished piston motor and turbo head. With no turbo my compression ratio is going to suck for a na motor. How do I tell if it has dished or flat tops?

BWRex Posted August 2, 2006 Share Posted August 2, 2006 Make a spot for it in your garage,and make a spot for it in your wallet! Good find!I'm seriously digging that '70's green....No joke.Is that the original color? Quote Link to comment Share on other sites More sharing options...
LLave Posted August 2, 2006 Author Share Posted August 2, 2006 Thanks, My friend that color you see is "leaf green" and is the original coat of paint. It like it too, it grows on you. Sort of like a fungus... Quote Link to comment Share on other sites More sharing options...
Forrest Posted August 2, 2006 Share Posted August 2, 2006 You'll need an FSM no matter what motor you go with. But yes, the engines are very similar. To see if the pistons are dished just pull out some spark plugs until you can see the top of one of them. If you have a low compression engine - don't despair. Just put a turbo on it!

Paz8 Posted August 2, 2006 Share Posted August 2, 2006 If it passed Calif. emissions testing why mess with the carbs? Drive the car, only way your going to know what it needs, welcome aboard. Quote Link to comment Share on other sites More sharing options...

LLave Posted August 2, 2006 Author Share Posted August 2, 2006 The car is smog exempt. I got it to fire up and it runs pretty good, although it is hard to tell with the 50/50 mix of good gas and nasty old gas. Not to mention the massive exhaust leak makes it sound a little funny. Once I get it on the road Im sure I will sort out all the kinks in a hurry. (Probably end up walking home a few times) Quote Link to comment Share on other sites More sharing options...
flames_187 Posted August 3, 2006 Share Posted August 3, 2006 yeah..i feel u on the gas thing...when i get workin on my z...i think ima just drain out the gas tank...i wonder if i take the plug off will i be able to put it back on?...lol..only one way to find out Quote Link to comment Share on other sites More sharing options...
