Supercharged K1293 - Target 200+ BHP
Turbo Mini Forums

I thought I'd start my own build thread, I'm not sure how long its going to take so I'll keep it brief and to the point and get lots of pics up as things progress.

The build: The plan is to build an A+ Motor and get as much out of it as I can. My Target is circa 200 BHP.

There's not much to show but it should become more interesting the further we go :)

A plus Block



K1100LT Head



K1100LT Head mounted on the block using the three original studs that are correctly located





Next jobs are to beadblast,weld and machine

Back Soon

keep us posted wayne, everthing stars with an idea

IMO anything over 160 bhp is insane in a mini

250 bhp is easy with this setup

I'm aiming for double that

If something is worth doing, it's worth doing half of.

You have to be mental to drive a mini with less than 160bhp

In the 13's at last!.. Just

Good point ^^

Decoking the head today :)

Heres a start............









Going to be getting deep inside those ports too :)

I just had the cams out de greasing them and I cant remember which one is inlet and which one is exhaust? numbers are 461368 on both and 495 on one and 489 on the other.



PS Also been playing with these, cant wait to start putting it all together :)

I've just found out that the 461368 means that they're the 256 degree LT cams. Which is good as that's what I bought them as :) still don't know which is exhaust or inlet :(

have you googled the numbers?, i know when i had mine i found a web site with loads of info, part numbers, cam timings it was a bike site of course

Yes i moved to the darkside

Instagram @jdm_brett

been googling for the last half hour. Cant find a thing

The service manual tells you which cam is which. I believe there are some indication bands on one or the other.

Thanks Carl,

The service manual states on page 29:

Camshaft identification.
Inlet: Groove after the thrust bearing
Exhaust: No groove

Just what I needed :)

that info is for the high lift RS cams..Can't for the life of me remember which is which for the LT cams, but as Carls said, its in the 'correct' workshop manual. Use the right manual to determine the inlet and exhaust, but in the grand scheme it doesn't matter which goes where as you'll time them up anyway.

The K1100 LT and 'RS' low lift cams are the same. K100 4v and K1200 are usually the saught after high lift 'RS' cams. The easiest way to determine which you have is measure the lobe lift. 'LT' cams are around 7.5mm lift while the 'RS' cams are around 8.9mm lift

as for which is which, i don't remember myself :) i'd be looking in the book or figuring it out with the location slots on the rear of the cams

It was the LT Service manual that I downloaded which states that 461368 are the 256 degree LT cams. The service manual also states that these cams are also identifiable by the extra groove after the thrust bearing. All's good now :)

Cam Chain tensioner mounting bar thingy removed Thanks for the removal advice Jimster!

Head all cleaned up and bead blasted ready to go for welding and machining now. One thing that has done me head in (Pardon the pun) and that's the exhaust studs. Who ever removed the exhaust simply cut through the studs, they'd rusted like hell and now Im struggling to get them out too. It looks like its going to the machine shop as it is and the studs can be removed there :)





Its looking a lot better than it did when I first got it :)

Get them to take them out when its hot for welding.. easy!

don't forget to weld up the hole the rod cam out of. Or you will have oil and water mixing

That's the Badger! :)

I've taken the block and head etc. over to the machinists today. I've given him the template supplied by Specialist Components but he's asked for the exact measurements for the stud spacing so that he can enter it into one of his machines. Anybody still got the numbers from having theirs drilled for the K Head Studs?

Tell him too measure it the lazy fucker. They are on a metric pitch so its really easy.
