failure was down to too much boost i.e 2bar before 1.5 was fine when i removed the pistons the ringlands on 1 piston just fell out looked like they had been plasma cut lol...chris

Carlos..
the rods arnt the problem and in inspection they were mint no probs at all the pistons wont take any more than 1.5 reliably and any one that exeeds that is looking for trouble ... was running 2.2 bar at one point when the pistons were poorly to see how everything stood up and every thing else was fine ran 2+ bar for 1000 mils maby more but the engine was breathing heavly by this time and i wanted to see how it went as i had spare short motor which was rebuilt with forged internals by me to slot in ...
Dyney
are you on 2.5 usdm sti?..
if so i would be realy carefull with std pistons and make sure you keep the boost down
if not take a look at my pistons ..... chris

Chris,
What have you used for your fuel pipes? Is it Mocal push on stuff, ala page 239 of the DT motorsport catalogue. JIC to 8mm tails?
Looks good and an interesting alternative to goodridges braided lines and fittings... plus the most appealing thing for me is it's a damm site cheaper!!!!! How you finding it?
Tony.

Think its the same stuff as that Tony, having seen it on chris's car. Its also what pavlo uses from memory. Its even cheaper from Think Automotive.
