ST205 3SGTE Pistons, Forged Piston Choice Options

[racingmcfly2]

Hi there,

Im new to this site, just found it today and what a site i must say, its just what ive been looking for!!!!!!!!!

Anyway im wondering if anyone can help me work out what pistons i need to run in my GT4 ST205. Its recently droped the rings on pistons 2+3, so im gonna need to get it rebored. Ive been looking at getting some JE pistons for it but the cheapest i can find them for in the UK is £580 for the 86.5mm

Looking on ebay and other american sites im looking at $500 for the same pistons which works out at about £270. quite a significant saving. However trying to work out which ones i need is a bit confusing

Part no 162109 which i have found on ebay http://cgi.ebay.com/ebaymotors/ws/eBayISAP...&category=33617

tells me that the Compression ratio of this piston is 9:1, but the standard celica ST205 is 8.5:1

But this piston is listed for the MR2 so does this mean that the valve chamber is a different size or are there different pistons with the same code at different CR

Any help on this would be greatfully recieved

Cheers Olllie
