So we know the following....

The Nappy head was designed to take in a bigger EGR without detonation improving emissions, economy etc. Better than the oppositions same classed donks.
C. chamber especially designed to avoid detonation.

The Turbo version made use of this aspect without intercooler for costs & not overshadow more $$$ FJ. Much like the XR6T over the XR8 for Ford.
low detonation CC + turbo = good, no turbo = kaka! :)

Achieving 200kw atw doesnt justify the harsh opinions snowballed from others.
Feral to name one made me look at the facts again to see why its misundestood.

It looks oldskool, simpler 8v, lighter & allows easier turbo layout than non crossflow setups? Bathurst record no FJ could beat. Facts not opinions.

Seen & hearing what custom EFI setups cost to setup properly by those who are not conversant in computers should be considered. Im keeping an open mind towards Stu`s setup which will perhaps only be 10% less overall than EFI yet 100% savings in fuel.
I`ll gladly accept a ride Stu of your tudor beauty, pay for LPG & lunch in next cruise!

Stu cant recall you said your head is mildy ported? You considered a 2nd Z18et head w/ 46mm inlets & porting? How is your twin spark ignition set sequential?

Ruredi you should speak to an engineer or you might as well club reg it if you only plan to drive a 1/3 of the year. Personally I get paranoid parking a treasured classic where I can see it. Even then when I can I want to bust the scone of those who walk past it too close with bags, keys or trolleys. Not healthy way to be unless youre a panelbeater.

Yeah the head has just been cleaned up around the inlet ports nothing major done. When I decide (or if its decided for me) to rebuild the engine I will look in more headwork. Im not running the twin spark dizzy ive got a s2 bluebird dizzy that has been graphed for the engine and has a boost retard fitted. Im also running an IC&E coil and 16v ignition booster to get a big spark for the LPG.

the z18 set the bathurst lap record in qualifying, then posted a dnf coz the donk couldnt handle the 35 psi. it still holds the record because the track is now longer. so the smokey z18 love needs to be clarified haha

see what i mean about using info to backup your argument that isnt all the truth? Ruredi, seriously do your research and make your conclusion because realisticly personal opinion biases advice. the internet is full of information, some of it is even true.

marks L series basic but well thought out setup (efi turbo) made 140kw at 8psi. to put it in perspective he sold the whole car for $5500 with suspension brakes etc. id be turboing an l banger for sure, suits the car.

its easy to dislike the sr 1600 because it is common, and the motors do have their weak points. but the bottom end can put out 300+rwkw in stock form and they fit in the engine bay like they were meant to be there. parts are plentiful and cheap, hard not to like it! ive put a lot of work and research into mine to make it super responsive and im proud of it. its no kawasaki head, offset ground stroked overbored sleeved ca19desct that runs on gas and cruises at 1800rpm (that suit 1000 wagons) but it does exist

good luck with your build ruredi!

Well this is why I am here...trying to research

mine is a 1200 coupe not a 1600. I can appreciate the SR thing but don't really want to go down that road for reasons already stated. Thanks for the advice.

Joe

sorry mate, was talking to D there. ive had 1200s, 1000s, 1600s with lots of different combos efi turbo carb, slow and fast so my advice is not 1600 biased. i have a 1000 wagon too. seems like youve made your choice, should be a tough car keep us updated

Quote:

I'm not really being biased here either...I just also want to hear what good things people do have to say about the Z18ET head and not all the negative. Both are helpful in helping me decide. Catch my drift?

100th Post...do I get cake now?

Quote: It could handle it all day but it was hotter than expected on race day "Fact" I watched the race I was 15 years old while you where maybe suckling LOL. Did you know what happened in 1983 when Nissan decided to not support the last round where he lost the TC championship by 6 points? Nissan used that time for development work due to constant and new restrictions towards a technology that was new to endurance racing in Australia. The turbo bluebird was reliable it won rounds at lakeside raceway, Amaroo Park (Silastic 300) and Oran Park Raceway. Failed after 146 laps at Bathurst not due to engine reliability but the turbo so let it rest.

Dont get biased part factual now you been doing well with your "opinion only method" all the way yet I fail to think it was your opinion but rather snowball info from others.

Quote: Longer by 45 metres yet if you where interested in facts the 1984 race averaged the same speed as the 1991 when Godzilla conquered the mountain. Truth? you are saying it smoked through Hardies Hereos? you where suckling remember so no truth there? The following year the FJ a superior engine to the SR in everyway was used due to the new rules otherwise they would have continued and improved the Group C Zet but where back to square one.

Quote: yes its very common and done to death.

Quote:
tik tik tik tik yes they do like the Zet its biased haters while Nissan battled alone w/ the Zet as its choice engine.

Quote:should have kept your bottom stock for a measly 220kw? I say measly because my old 51 mm carbed 13B almost made that in NA BP and bang on in PP.

Quote: Wrong, they werent meant to be there unless you like something that looks ricey and out of place with the year of the car. A Zet fits straight in & suits the era. An L would have been more attractive and original with 220kw atw in a 1600.

Quote:
We seem to know that but for all the money, effort and common steps followed from other common SR setups its still an underpowered SR. Cheap to start but not in bulletproofing it or making big hp without spending a bucket. There are CAs doing better with less money.

Quote: CAZX19DE for the sheep out there that follow sheep, is individualism a crime in sheepish eyes? I remember you asking me via PMs if a ZA18et could be made to fit your 1000 wagon and thanks for all the gratitude when you where eager to learn what a waste of time me botherind with a detailed and long replies to dry the moisture behind your ears.

Quote:
Thats why some dismayed sr20det owners couldnt keep up with the vb10 with a mild a12 cause of the 1800rpm.
All that boost and they couldnt shake it up the climbs or keep up throught the twisties only to later be asked "what engine is in it" and "what suspension do you run it seemed to have no body roll". I even stuffed my pissy 4 speed and diff but it was worth their embarrassment by saying its not far from stock.Y
For all I knew you where in a double story bus on your way to bend over for the queen and wondering if a Z18et will be your next project for your 1000 wagon.
You are trying out a pissing contest with a 40y+r old thats had more cars and women than youve had rasberry slurpees.

ha, mate you are a funny bloke... my purpose was to try and give poor old ruredi a balanced argument. i did ask you about the fitment into a thou as i was overseas, and did appreciate it as i knew you had tried and had the figures. I then kept searching for info and found info, and some threads you were involved in (so you know) the z head is not the best. You are a guy who reads the whole internet over daily, so you have heard the arguments. maybe thats why you sold it? there are better options if building from scratch- its arguable that the common old L head is a better option. of course it will work, and it will make good power - anything will once you cram boost into it

your snide little comments trying to personally belittle others, me in this case can get #OOPS#ed. why try to make yourself look better or more knowledgeable by bringing down others. sheep? give me some credit! id like to think that ive had enough cars and played around with them enough and been actively involved in the datsun community not to cop the sheep tag. the advice im trying to give is based on what i have seen and experienced. but you are older, have a more powerful a12 than me and know way more useless #OOPS# than i ever care to so you win.

Please, put your ego away Dave. Calm down.

Ruredi,

Are you after something to drop in or do you intend to build something up?

I'm leaving AUS shortly and I may be getting rid of a few engines. I have a few interesting combinations and I would like to get rid of some as I cannot take them all with me.

All a-series of course.
