A high school buddy bought our car in 1983, we bought it the following year. I've purchased 3 parts cars over the years. I probably should have kept at least one as I've got enough parts to have a fun street car.

So I'm rapidly approaching the 35th year of ownership of the Pokey and I've been on this site nearly for 17 years. I also know at there are folks who've probably owned their cars even longer.

So out of curiosity how long have you owned your car?

Great photos of other peoples cars, Dave really that tatty coupe...……..Oh wait that's my car

I love the GX coupe above but let's be honest after I got done pounding over kerbs and staying glued to peoples bumpers despite all the gravel they're flinging up onto the course it wouldn't look so pretty.

Stan...……….now I remember why we painted my car in the garage.

Thanks for posting the information and photos; I guess the title should read "will not fit without modification"

Very cool build.

Benny thank you so much.

I seem to recall the Mini has 21mm pin but yes the pin height is 26.5.

Was the A15 crank modified at all?

Were the Mini pistons OEM/replacements or from someone like JE, Wiseco, Wossner etc?

I've sent them an email but didn't get a reply.

If someone could contact them and ask if

A. are A15 1mm oversize pistons available(they are listed on their site)

B. If so what is the dish volume (assuming they are dished pistons)

Thanks in advance.

So as clearly I was bored yesterday I tried an A15 crank in an A12 block and there are issues.

First the block in question was a 73.75mm bore. My intent was to use 75mm Honda Pistons in my A12A block

I used the standard A12 rod and piston (knowing th piston was going to stick up 2.5mm), the connecting rod fouls the bore. I didn't measure but the top of the rod bolt contacts the bore so I'd say it needs at least 5mm more clearance.

Next I pulled the rod and piston off the crank; the crank throw contacts the block about a 1/3 of the way along the surface of the throw.

So a couple of things; an A14 crank may fit without these issues given the shorter stroke, the A15 crank might clear the A12A 75mm bore block but I doubt it so I won't be trying it.

I'm trying to use off the shelf parts hence cast pistons

My A15 blocks, with 76.5mm bores are scored so I need to go out to 76.75 or 77mm

I may use either 76.75 A14 pistons in my A12A block or try the 75mm Honda piston with either A14 or A15 crank in A12A block.

I'm just trying to get my car back to the 90-100whp range because the current 75whp is painful
