She's a 1990 Phase 2 BX 16 valve, the body is absolutely immaculate underneath, paint is faded though, but it looks like it will polish up.

Engine bay was full of leaves, but the body and chassis is absolutely perfect.

The car has the wrong (A phase one) rear bumper, but there is a rear phase 2 bumper in our massive pile of BX parts so it's all good.

Plans are new liners (It has 102k miles on it so due a rebuild although the leakdown was good, it may as well get freshened up now), stem seals, new piston rings, put my spare Jenvey throttle bodies on her, Emerald K3 ecu and new hydraulic return pipes. Will make a nice retro daily driver. Should be nippy enough at that to see off most modern 'hot' hatches.

rear shot, light clusters are in the boot.


Interior is in great shape - ignore the stuffing on floor! Was from the spare interior being stacked in it


needs a good tidy up in the bay, but everything works.

Only just getting to do something to this now! Didn't get a lot done today, just started to strip down - got the new radiator in as well though.

Will be getting the head off tomorrow then the pistons out to put new rings on. Will need valve stem oil seals as well.

Then it's on with the Jenveys and the sporty inlet cam!

Made some progress today, got the head off and was pleasantly surprised by the liner condition.

A hone should be all I need to do to them before firing on the new gapless rings.

Had a bit of bother with one of the bolts, some bellend must have had at them before with a poor fitting driver and broke a bit off it. Will be replacing them anyway

Cam cover off

liners are better than they look here



head off on the 'bench'

Got the barge into the garage with the lift today, got the non standard front bumper off and stuck a new door seal on the drivers side.

Bodywork won't start until after all the mechanicals are perfect.

underside of the car is completely rot free - you'd think it had been kept in a bath of oil!!

Anyway, few pics

Outside at last (You can see how well the paint is going to come up - i did a test patch on the bottom half of the drivers door, it's coming up like new, and that was the worst bit!)

in the garage at last for the fun to begin!

Got an hour this evening to get a piston out to send off to get the correct sized gapless rings.

Tightening down the improvised liner clamps


Bores are in very good visual order!!


Piston out, connecting rod off


Big ends in good order as well


In the box ready to get a new set of rings

Started to get a bit more done today with the head

I'll open a new topic on the toyota when I get it back from being painted.

Been flat out studying for CCIE security this past week so not got much more done to it apart from some wiring work. Have also to sort a megajolt on a friend's stock car.

Piston rings and a set of XM V6 spheres (Will make suspension stiffer) arrived so I'll get the engine back together at the weekend.

Got the head back together at least this weekend

The valve collets were ridiculously tricky to get in with a normal spring compressor and small screwdriver with grease on it!

Valves in and springs mostly in


'special' stem seal tool - 10mm socket


fully assembled, bar buckets


test fitting the piston rings once gapped - note the top ring is in 2 pieces, a rail on top and the ring below that forms a gapless ring.


Putting the buckets back in


camshafts back in


oil spray bar back in


Unfortunately it looks as if I will have to replace at least one liner, as the ring clearances uncut were too great, so going to have to look about that this week.

High lift inlet cam has been ordered but going to take 4 weeks to arrive, so building up with standard cam for the time being.

This week I should have the engine back together assuming I get the liner(s) I need.
