tuff pistons for supercharged 4K.. what other makes fit?? Mon, 14 November 2005 13:41 Go to next message
Hi, I have just pulled apart my supercharged 4K and found 3 cracked pistons!!

What I need is stronger new pistons... forged ones will cost around $1200 plus from SPS in Melbourne... As a cheaper alternative, has anybody found pistons from other car makers that fit either 4K or 5K?, (Ideally from a turbo engine for lower compression, around 9:1 or less).

I have done hours of searching and have not found much yet. It seems Gemini, some Mazda may be close, but I think a piston from a factory turbo should be stronger??. The ACL catalogue that I looked at didn't show comp ht, or pin diam.
I also found a reference on the net to using 1G-GTE pistons in a K motor, but so far I haven't found the specs for the piston and rods, apart from the 75mm diam.

Any comments or suggestions/ info appreciated.
Thanks, Kevin.

you need to find an old ACL cat, they have pin heights etc...

the ACL pistons are much better than the repco/toyota ones which, as you found, usually come out in pieces..

for a cheap effort, i'd go the ACL's first...

if you are getting serious abtu it, get shrter pistons, lower pin height and overall height, and get longer rods...

I've got the computer proggy of the ACL catalogue (no idea how or why, but i do) and it seems to have the specs you want

ed: Better yet it also has a list of what other motors the piston kit you have selected is used in

No, I think he's talking about the ACL parts catalogue PC application, which at one point was available for download from the ACL website.

I've got the old PDF with pin diameters, compression heights etc. but no hosting. It's 15mb.
