Car unfortunately had to be sold.

The family problem that caused me to advertise it last time had resurfaced and I didnt have much choice. It's a sad day...

:(

Ok well I'll say 200KW ATW is my target.

From what I know, the combo suggested should be more than capable of that. If anyone can suggest an option better then as I have said (taking into account weight, cost and ease of conversion)...I'm all ears?

At the moment it's the clear choice as it ticks all the boxes for my requirements.

For a 1200:

14.0 sec. quarter mile: 155 NET HP
13.0 sec. quarter mile: 190 NET HP
12.0 sec. quarter mile: 245 NET HP

However, if you increase the weight of the car you'll need more power. Z18ET will add about 250 lbs to a 1200.

1200 + 250 extra pounds
12.0 sec. quarter mile: 280 NET HP or 235 RWHP

The most critical part of getting a low ET is the rear suspension. The tires should not slip much.


I'm not planning on using the complete Z18ET. Only from the head an up. So I don't think it's 250 pounds.

What does HP equal in KW?

230-280kw at the wheel's is alot of power to be expecting out of a Z/L combo im sure its achieveable but not without investing a lot of time and cash which it sounds like you may not want to do? Mine's making around 160kw at the moment so with a new turbo im hoping for around 200 with a few tweaks in the tune.


Oh ok. I thought you were already making over 200? Must have misread.

What do you reckon your car would pull on the 1/4? If I could get mine to pull a consistent 12 sec pass, I would be happy. How much power would be required to get it there, I do not know. 230-280 was my estimate.

Well...I was not expecting ANY of that.

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.


Mate I was originally planning on converting my A15 to EFI and adding boost but I'm not sure that I would be happy with the end result. I'm looking to achive 230-280 kw atw. Doubt I can achieve that with my worked EFI trbo A15?

Then started looking at other options. Don't like the CA or SR as I would like to fit an older engine to keep with the era plus they are pretty heavy.

The reason I am here is becaue I don't actually know much about these engines and what makes what power. You people have all had your own experiences and know better than me at this point.

The combo suggested appeals so far for several reasons.

1. Weight - very light when comparing to others
2. Cost and availablity - have bounced around a few figures and appears relatively cheap even when including machining and some mods.
3. Z18 head is factory efi and turbo so simplicity of efi turbo conversion
4. From what I'm told and from other members cars (Stu's 120Y) it appears that the power I am after is achieveable???

I am looking at building something from scratch so the options are all open to me at this stage. If someone can come up with a counter or different combo which trumps the above main mentioned points...then I'm all ears.

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


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?

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.


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

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!



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

I'm enjoying the difference of opinions here and I encourage them to keep coming.

My opinion:

Now I don't know as much as you guys all do as I'm still learning however in relation the Z18ET head that a lot of people are dismissing...

1. It has been used in race applications with some very successful results. And still is being used by some (Troy Morrow) with impressive results. I'm sure they are not standard heads and have had plenty of work done to them.
2. Stu is using it on his 120y and from what I hear and see...it's a pretty cool little weapon...if i could get my car going with those numbers i thibk id be happy. He's running it on gas also...so I can only guess that on petrol it might even go better (not to bag your setup at all Stu)
3. Ease of using the standard efi setup than converting an L series???
4. Many of people have used this head with good numbers and have had good results.

So to say that it is a "dud" is probably a bit far. There is still plenty of good about the head.

It's a 1972 Coupe. I don't think those mounts will go into mine??

Will I have to change the teams tunnel to use R30 stumpy? If so which tunnel to use?
