yes, will go and see what they have tomorrow, and also motor factors to see if they have copy ones...

Time on my hands today and i found these:
Toyota 3ZZ engine (from a corrolla... all taxis here are corollas and parts for these are very cheap) worth having a look at also...
TOYOTA 3ZZ piston
part No 13101-0D070
qty 4
Piston dia 79
piston height 52.3
comp height 29.9+2.4-4.0
pin dia 20
pin length 50

Just had a look through Google & found this

Looks like pistons can be bought at $40 each. The ring set is expensive though, so maybe try sourcing those locally. There might even be somebody cheaper, like

Sorry, just had a look at that last one, lots of junk, but maybe some of the links can help. Why not try going to a Subaru dealer & see what they can supply.

No, but they are often less expensive

i'm thinking that for my application forged pistons are probably not required ?

Custom forged pistons are only $400/set from Arias and other piston manufacturers.

Kamieiri is the most expensive brand in the world.

i'm hoping the justy piston option will be cheaper than these !

Just re-read that last post and changed my mind, i shouldnt give up on the 79mm idea just because its slightly more difficult.
A 1608cc engine would give lots more torque to help overcome the high gearing and my somewhat lazy driving style and it would be something to be proud of...
ive decided to go ahead ...

So, new spec
79mm justy pistons and pins, A15 block, crank and rods.
factory 70 degree grind camshaft, weber DGV, tubular exh manifold, H89 head, thinner head gasket, decked block, electronic ignition....

have i missed anything ?
How about the justy pistons, do they have the offset dish to help with the quench effect of the H89 closed chamber head ? or would a H75 head be better ? ( i have both under my bench)
What CR should i be looking for (91 octane fuel).

Again.. pls feel free to criticise !!

yes, i thought about 79mm and read about it in the excellent tech wiki here...
i have a problem that its difficult to communicate with the machine shop.... they are great and helpfull and if you turn up with an engine block you dont even need to speak to them and they will just sort it out for you within a day, but i'm a bit worried about getting something out of the ordinary done such as special small end bushes as it has a high likeliness of screwup... if there was some off the shelf pistions which used the standard A15 small end pins then i'd be happier to go that way... decking the block if required would be ok to do....

Its still a high rpm cam ... as is the stock A14 cam, and it sounds like you don't want to rev that high.

Suggestion: if spending money on new pistons and boring the engine., why for t the little 77mm pistons? 79mm versions will return more power than the other change.

i'm in Thailand and have given the cam to an Australian friend to take back home for me and post to the grinders internally, then it will have to be shipped back to me by airmail.., so it dosent matter really where i get it from, but Wade seem to have a good rep and responded quickly to my initial request...

I thought the Wade suggestion seemed a bit too big... thats part of why i posted this.... but my understanding is that a cam which will be lumpy and peaky for a 1200 would be more civilised for a larger engine by virtue of the capacity.. or is the capacity spread we are looking at here too small to have an effect ? i assumed the rev specs would be based on the 1200 as bigger engines would be more flexible..

Spec i gave to Wade was for best power at around 3-4,000 rpm range..
