- A run-through of what parts were needed to get my early K11 to run on ITB's
the car made 149hp at the flywheel / 125hp at the wheels when it was mapped in March '21
very happy with the results

Hi, awesome engine build(s). A lot of usefull info too, thanks for the video!

I found the same timing my 774 cams for my mini's cg13de, I was able to create some adjustable cam gears (sort of) by giving an old cam and standard cam gears to a machinist he was able to use an indexing head to rotate 3 teeth and add 2 crank degrees, 1 cam degrees, and drill a hole for the dowel, 6 holes spaced evenly gives up to 6 degrees of advance and retard, each tooth changes 15 degrees I think so further changes could say advance 1 tooth and retard 4 degrees, 15 - 6 = 9 degrees of advance. It's easy enough to move the gears that you could tune cam tming on the dyno, a bit more precise and reversable compared to filing the dowel pin. Just an idea if you want to tune cam timing.
Hi there where did u get the cam gears made
@@neilbeckwith567 a local machinist was able to drill 6 new dowel holes with 2 degree (camshaft degrees) offsets so I can advance / retard 2, 4, and 6 degrees if you want more adjustments you can start moving the tooth the chains on, one tooth is something like 13 degrees.
Nice build!
Hey cool Video!
If you could choose between the 1.3L CG13 or the 1.4l CGA3 Engine, which would you choose for a high power/rpm N/A engine? Thank you
The CG13 has stronger pistons and will make more power with supporting mods due to a being able to rev higher, but for a budget (ish) build, the CGA3 bottom end is good as the longer stroke gives a little more torque and will handle 7k rpm pretty easily, for ultimate spec a built 1400 forged bottom end from IK Engineering is the way to go
@@bashracing5249 Thank you for that quick answer
@OppaiGeek you'll need to bore the cylinder out 1mm but yes is's possible, I would have a look into fitting the pistons from the 1.0l engine though as they are direct fit and raise the compression of the 1.3 giving a good cheap power increase
@OppaiGeek speak to IK Engineering they do forged cranks
Just subbed. Can I ask if you could measure the engine? Want to see if one would fit in my old Mini. Front of the exhaust man to the furthest point on the throttle bodies, width of block and gearbox and rough height? Would really appreciate it. Thanks Mike.
You can a lot of people have fitted a micra engine into the mini.
@@zezex3116 Its the throttle bodies fitting thats important to me
I've got one in my mini, I've chopped my bulk head out and moved it back about 25mm but have got around 40mm gap between my manifold and front of mini. So didn't really need to do the mod to the firewall. I have got a flip front tho I very much doubt you would get one in the standard body without cutting inner arches and that sorta thing.
@@Classic_Re-creation you can without cutting the wings, as for throttle bodies people just angle them up more.
What have you done to the valvetrain in order to make it rev up to 7k
Stock cg13de can rev to 7000 almost
what cc is this engine?
1348cc
Hi currently doing similar mods to my car I have the ford wasted spark coil pack could you let me know what sparkplug wires did you use?, Thanks 👍
Hi, They're custom ones made by formula power with micra plug ends and ford wasted spark coil end and are plus 300mm long over standard
How much did this build cost roughly, and could you post videos of it driving/idling
The engine was roughly £2.5k, sorry don't have any driving bids at the moment, but may do so over the coming months
@@bashracing5249 not too bad. Im trying to decide what route im going to go either turbo or itb.
@@bashracing5249 did you build it yourself or is that just the cost of parts and you did it all yourself?
@@kieranmaharajah6933 yeah built it myself, so no Labour on that price
@@bashracing5249 thank you I'll be building mine in summer once I get the space!
This the 1300 engine ?
Yes but the slightly later cga 1348cc
0,5mm skim on the head? From a stock 9.5 C/R on a steel 0,5mm Nismo gasket you would have a C/R of 10.5. So this is probably around that.
Are the bike throttle bodies progressive enough for using on the car? I know bike carbs aren't great as the butterfly opens too quickly
I changed the pivot point on the micra pedal to lengthen the travel
Great video. I have a cg13de engine that I will be putting into my classic mini next year and looking to do a few upgrades. Do you know the part number of the ttv pulley with trigger wheel? Also, are you running a cam position sensor for the ecu?
Thanks buddy, TTV item number 3005, no need for a cam sensor if you're running standalone management,
Can you provide me the part number of you're icv, I had a Nissan Micra k11,tnx
hello, nice engine build. i would like one question please. it is possible change my ignition distributor system for the ignition system which dont ingludes distributor? beaucause my distributor has broken in the engine part, one leg in the cams has cut... and dont need again...
you would need to change the ecu to a standalone run anything other than the stock distributor
This build on insta mate ? Any videos ?
there isn't buddy, sorry
Any chance you could send a link for the trigger wheel please?
Great video thanks for all the insight in to the mods done, is this all on the standard bottom end? Impressive if so revving out to 8k - what you have is similar to what I’d like to build, though ideally I’d like to get some decent rods (not found a supplier as yet), have the crank bladed/wedged, flywheel like yours then have the lot balanced; I’m hoping that lot would give something you could rev to >8k safely but not found much info on the internet… lastly please get some videos of it under load, she sounds great!
