Yes a Buick Too Jeff .

http://www.classiczcars.com/photopost/showphoto.php?photo=284 This is a original Gnose with a nice front spoiler it's gotta be my favorite Fairlady Z I love the Wantanabe wheels. :classic:

Not a problem the topic of which head is best is a hot debate in the Z car world. You'll get many opinions but generally most agree the P90 head flows best. I have a friend with an N42 head on his turbo L28 he's getting 200+ kw at the rear wheels so it just proves that there all capable of big numbers with money. Cheers.

I tend to agree with Alan and believe that the original Gnose looks the best. From what he's told me and I've seen personally the original was of very good quality and I refuse to put a gnose on my car unless it's the original factory style 5 piece. I've seen alot of Z's here in Aus running around with fibreglass copies and there just not as good. check out www.geocities.com/spized1969/ for a look at what the real deal looks like. Or see Alan's gallery for the full ZG kit. I have a few in my gallery also that I believe are of factory standard. Of course your more than welcome to buy it just wouldn't want you to pay good money for something you won't be happy with :classic: .

If this is correct looks like I'll be getting one as a daily driver I've always wanted one but prefer the early Z's. I don't know about TT as they are gonna be a packet to maintain but a non-turbo would be a great car for everyday use. I have a friend at Uni who manged to get one for 8k and I haven't been over however it's pretty clean etc.. not sure about it's condition mechanically and I haven't had a look at the underbody for evidence of an accident but it sure looks nice on the outside.

Thanks Brett I was trying to answer questions where I wasn't 100% sure but looks as though I was nearly correct which is good :classic: . I have an early E88 on my car currently and I am pretty happy with it because there supposed to be almost indentical to the early E31's which had the high compression and good non emission controlled design that the later 260z especially heads had. The E31 is a great head once you mod it a bit it suffers from small valves and ports but my engine has had the larger ZX valves installed and been ported etc.. to suit the L28 bottom end. I would use my P90 for an N/A application but I would rather save it for a later Turbo project. It's a bit of an Um and ah decision to turbo my Z but the way I'm going I'll probably own 2 Z's again (Note I said again :classic: .) I currently only have 1 however and the spare engine isn't really in my way in the garage. I suggest TexasZ that if you really want to learn about the L-Engine you have a read of the site posted above and go through a book called "How To modify your L engine" forgot exact title and don't have book with me but it talks about the things you can do to the L engine heads and I for one haven't read the whole thing just bits and pieces. I've seen many different heads used for turbo Z applications even the E88 has been used with good results. I know of one Z putting out around 500HP with an E88 on it. What it really comes down to is budget. This owner decided to go with the E88 because he could get away with no emission controls in his state in the US if he had of used the P90 he would have to comply with the rules of that year of engine. Anyway I'll leave it there if you have any more questions I can answer by all means ask. :classic:

Alot of people don't actually want to change the head because they feel Nissan did alot of research on getting it right. You could increase the size of the exhaust ports give them a polish etc.. but the main problem is it's difficult to get the higher compression ratio as it was designed the be a low compression engine for the turbo. I'm hoping my P90 wasn't shaved to raise compression and that only the pistons were changed but even so it would only result in about 8:1 compression which I would believe as my high comp E88 feels alot different very torquey nice to rev. Anyway I'm not an expert on the science of Engine heads still a learner hopefully someone else can chime in and give you a bit more detail on the subject.:classic:

When I was gonna attempt this I was planning on getting a rotissorie can't spell it. You know what I'm on about :classic: .

From what I gather the P90(I have one aswell) is the best engine head in terms of the way the combustion chamber is designed and it flows the best. This is because it was the Turbo head apparently I've heard the P79 head is identical but the non turbo head. The P90A is the oddball because of the Hydraulic lifters that bleed and become useless because finding replacement through Nissan is near impossible especially here in AUS as we never got a Turbo ZX. The reason we recommend the N42 F54 combo is budget. Basically you can mod most of the L series heads and get great results but it all comes down to how much you spend on the head. The P90 is the best for turbo but it's hard to get higher compression without spending the big $$$. :classic:

THE PHILOSOPHY OF LIFE A philosophy professor stood before his class and had some items in front of him. When the class began, wordlessly, he picked up a large empty mayonnaise jar and proceeded to fill it with rocks - rocks about 2" in diameter. He then asked the students if the jar were full? They agreed that it was. So the professor then picked up a box of small pebbles and poured them into the jar. He shook the jar lightly. The pebbles, of course, rolled into the open areas between the rocks. He then asked the students again if the jar was full. They agreed it was. The students laughed. The professor then picked up a box of sand and poured it into the jar. Of course, the sand filled up everything else. "Now," said the professor, "I want you to recognize that this is your life. The rocks are the important things - your family, your health, your children - things that if everything else were lost and only they remained, your life would still be full. The pebbles are the other things that matter such as your job, your house, your car. The sand is everything else, the small stuff. If you put the sand into the jar first, there's no room for the pebbles or the rocks. The same goes for your life. If you spend all your time and energy on the small stuff, you'll never have room for the things that are important to you. "Pay attention to the things that are critical to your happiness. Play with your children. Take time to get medical checkups. There'll always be time to work, clean the house, give a dinner party and fix the disposal. Take care of the rocks first - the things that really matter. Set your priorities. The rest is just sand." But then a student took the jar which the other students and the professor agreed was full, and proceeded to pour in a glass of beer. Of course the beer filled the remaining spaces and soaked into the said within the jar, making the jar truly full. Which proves that no matter how full your life is, there's always room for a beer. ------------------------------------------------------------------------------------ Personally I thought it was really important till I read the last bit. ------------------------------------------------------------------------------------

hahahahahahahha well I've never had to grease nipples before. Touch , grab, fondle you name it but grease well never. It's a new concept to me but I think I've got the hang of it. Just don't suck on them and I should be right unless I like the taste of grease. :tapemouth

Basically the best way to get good compression from factory parts is to use the F54 engine block and the N42 head it gives you 10:1 compression roughly and you get the bigger valves and ports etc.. There is an engine calculator on this website under the download section if you can't find it I'll email it to you. My car is running early E88 head off a 72 240z and F54 block get's 10:1 compression and has had a mild cam installed with ZX valves etc.. It goes pretty well in tune previous owner claims it had over 200HP but he was running tripple mikuni's I'm planning on setting up mine on the SU's and having the car get onto a dyno at a fuel systems place to get it running just right. At the moment I get detonation on premium depending on if I open it up WOT and I try to avoid driving it in such a way that it will ping. Until i get her adjusted properly carbies wise anyway I believe it's running too lean. Anyway an electronic dizzy does wonders to the way the car drives trust me it's bliss. TexasZ if you don't run premium you will get pre-ignition as TKR mentioned which is basically when the spark is fired before the piston reaches TDC or just after. To get a car to fire on TDC is very hard btw, anyway this causes the car to basically work against itself and loose power not to mention it will destroy the pistons and could even put a hole in them. If anything I've said is incorrect don't hesitate to correct me guys. :classic:

I looked through your gallery looks like your doing a great job on her. I hope to do the same justice to mine one day but at the moment I need to be able to drive mine so it's not practical. When i finish my schooling I'll get a run around I saw your Mirage :classic: I had a corolla for the same purpose but it was costing too much. You won't believe how much better a Z is to drive once she's finished. Keep up the good work and it will all come together one day.

Thanks for pointing that out and thanks for the advice on parts. I feel going authentic OEM is the best solution in most cases. Let's face it they were made for the car and they have the best quality as far as I'm concerned paying a bit extra will not bother me if it means buying something that will last. I think that's half the problems with cars is that replacement parts that are used by some people are just not up to scratch. To me it's like buying a fake Rolex watch and a real one. Sure they look the same hell they do the same thing and even if the original is overpriced it's because of the cheap imitations and the fact that it has a reputation for making good quality products. END RANT . Cheers

Don't hold out selling the rear wing, I shouldn't be buying toys at the moment I need to pay off my car and fix problems besides I'm still not 100% on it just yet so if u can make money on it and it brings you closer to getting your new car sell it man :cheeky:. However I really want the Unisyn and I WILL BUY IT provided she works . I might be interested in some of the other stuff if you get your old burnt out Z back :disappoin . I think mainly the stuff I sold to u in the first place ooops :stupid: . Anyway cheers speak to ya when I see ya online!

I'm not sure about the boot I put some in and I think some came out from the boot but the boot apears to have a small hole in it for grease over flow I have to get a flashlight on it. Hmm if I have split it are new boots available? I consulted the guy who supplied them and he believes that it could be the steering rack bushes causes this "new" noise either way I should replace them with the harder poly sort and he thinks I will notice the difference. At the end of the day If I have screwed them up I will just have to live with it and get new ones. I'm wondering though if it's worth getting those ones at Rare Spares for half the price or if I go with my gut instinct and get the expensive ones??? Experience has always taught me pay good money u get something that has been put through a good quality system.
