hey guys just a quick question. will a set of forged e15et pistons fit into a A14 or A15? if so any mods? i gather the A14 block will need boring out and a A15 crank? sorry to hog main forun 2 :P

Yea mate you will find they will fit but with some modification to the piston.
i am going to be running these in my turbo a15(not forgies just standard e15t pistons )the e15 piston is almost identical to the a15 in dimensions except for the compression height. all that needs to be done is some top of the piston has to be shaved off( not sure how much exactly as i havnt got that far ) otherwise the piston will pop out the top of the block . they will be my cheap forgies lol

E15T- BorexStroke: 76mmx82mm,
connecting rod-137.5

A15- Borexstroke: 76mmx82mm
connecting rod:133mm (centre to centre) according to Wiki

piston has to decked about 2-3mm from memory.

Are these piston standard size?

Yea i think its bout 3 mm but like i said havent got to that stage. i am running 20 thou oversize just to clean up the bores

This has been brought up before but..

I have had a motor running these. We opted for the A14 & as stated above, they still need a slight shave. Certainly do-able. Stockers will be good for ~14psi.

one of the best pistons for under 14psi is daihatsu charade cb
28mm pin height part number 3MKRY2896
76mm and 77mm oversise
18mm pin diameter

Using e15 rods (40mm ends) you can offset grind your crankpins
for 86mm stroke and run these pistons for 1561cc or 1602cc capacity.
Rod stroke ratio will still be better than Honda B series / turbo.
