how much boost can i run on uk pistons
i have a uk my00 which has the current mods
PPP ecu
sti ver 8 intercooler,walbrough fuel pump,
full decat system with open neck downpipe and an IHI VF 30 turbocharger just how much boost can i run on the std uk pistons and other internals. Does anyone have any experience of the boost levels which are safe to run at. with a remap what levels of boost are obtainable on uk internals.

With a boost controller (no re-map) about 1.15-1.2 bar but because you have changed the turbo you should have a full remap anyway.
My local tuner told me you can run about 1.4-1.5 bar with a full remap done properly. When i get mine done i'm hoping to run about 1.4 bar. If you get the map done by someone who knows what they are doing they should only do it to a safe level anyway. Try contacting Andy Forrest Performance or BR Development there both supposed to be very good.

main reason for asking was that i have been informed that the stock uk pistons will not support these levels of boost without destroying themselves and that i would have to install some uprated forged rods and pistons. Can anyone verify this or does anyone run higher boost levels on stock uk internals

Obviously with supporting mods and plenty of fuel

Longevity?
You can run this kind of set-up on stock internals but there are sooo many variables.
What mileage is the engine? How regularly has the engine been serviced? has it always been warmed up and down? How often has it been redlined or subjected to continuous high speeds? Even if all of the above is in place there's no guarentee that the engine won't go bang.
One solution is to go down this route with stock internals and when the bugger does eventually let go then you can look at the rebuild and have all the supporting mods already. IMHO of course.

If it's mapped properly and you look after your engine in terms of adequate warm-up etc, your gearbox is likely to give up before your pistons at 1.5 bar boost plus.
No guarantees though.

thanks for the help on this, I was informed that i could not exceed 1.2 bar on uk internals. i know the car now requires a remap but what is recommended either a TEK 3 remap or Apexi from andy f.
