#30 Re: Is a CR14DE a viable conversion? Let's find out.

So I fitted a time sert to the block. For those that don't know what a time sert is, it is much like a helicoil, only better. A helicoil is wound into a retapped thread using a tang that is later removed (if possible) and is wound in to a specific depth with no restriction. Loktite doesn't work too well on them as it tends to seep through the threads and they pull out fairly easy. If they get dirty you can't run a tap through them. You will most likely break the tap. While timeserts are one piece, are set to a solid depth as they are flanged, you can use loktite as they aren't porus and once they are in they are broacked through with a tool. Sometimes they come out but if they do you just replace them. Easy peasy.

Before and after. Notice all my tough tools, datsuns and my hello kitty radio...

Then I started the never ending grinding. i managed to get it very close. But I am going to repair the grinder tomorrow and slice through the hump at the top of the casting thats giving me grief.

But it wasn't enough...

But theres still more to go. It is definately going to fit. It is just a matter of how much material I remove. Too much alloy shavings everywhere.

Photo's are awesome

Very interested in the starter problem is there any info out there on a different starter for A series

I feel a search coming on eg http://datsun1200.com/modules/myalbum/photo.php?lid=20829

Thanks for posting these in progress picks so much better than expected keep up the good work

When I got home I did a quick research and found that, depending on what site you can believe, they put out 72kw @TW with the auto. But another suggests 63kw @TW. I'm going with 63 as it seems to be consistant with other various makes etc.


D, In my origional post I did mention that there are some discrepencies between different sites. So I went for the lesser value purely as a base minimum value. To me it makes sence not to go with the larger value. In the end, you will be dissappointed if you have less than your target value rather than more.

1200RC, the dizzy is fitted to a CG13DE. The CR14DE uses crank and cam sensors. Although the crank trigger is taken from the flex plate I am confident that is a small hurdle to overcome. Which means that the CR is capable of sequential fire.

I borred a time sert kit from work today so I am off to the shed for another round. I am keen to sort out the starter motor side of things.

you've got to watch those blades on aluminium alright. they're notorious for preferring human flesh to ali. A thin abrasive cut off works ok on ali and is much safer.
I'm another following your progress with interest. Looks like a great idea.

yep, sounds good then, if all the mounting things can be sorted the only other issue is fuel system

gonna be able to convert for under $1300??? Lol

what's the story with dizzy on this motor, you mentioned something but I couldn't make sense of it, is it out the back of the head or it doesn't use one?

the figures you quote at 63kw are higher in the Cube at around 68-72kw atw
its got a peppier tune for the heavier cube. Also remove power steering and
air cond units and you have freed more kws without a cent.

Cheers Mick, and others too.

As for advantages. How about you can buy a CR14DE for as little as $550 as a low KM motor from almost any Jap wrecker. If they put out 63kw ATW, that, combined with a manual is approx 70kw which is around 95hp ATW which to me is a pretty good advantage. That's a bit more than a mild A14. They are cheap to rebuild, weigh bugger all, have 16 valves, vvt and a cross flow head. There are some mad Europeans turbocharging them and getting upwards of 300hp out of them but I haven't looked that far ahead yet.

If however I had used a CG13DE from a K11 Micra there are different cams etc from Tomei. The CG13 has a pressed metal sump and a dizzy ant can punch out over 300hp.

As the CR is lighter by at least 10kg, combined with a slightly heavier gearbox, you are effectively going along the same principles as a mid mount conversion.

Combine this info into a light car and you may just have a serious package for the street or track.

Disadvantages. Not a straight in swap and may attempt to spill the contents of your stomach everywhere.

With great gain comes great pain- shame about the shirt. Lucky you didn't cut the cord too for a zap.

Looks nice so with the cut out bits are they structural so far?
