Sam was running unto 40psi at points and never needed any of this decomp plate shit. Man up and get it bolted on.
If you do really want one, i would imagine it would be a custom job.

Yeah but look how his engine faired.
As with the 2.1 my aim is not what max bhp I can get till it blows up and I start again, no, I want a reliable revvy low boost tnad!
Its such a dependable little car I wana get it right
Wasnt sure if diff pistons may do the trick or just having them machined
Its also the wifes car and I wana do it all as a surprise

Skim the pistons posibly if not laser cut a head gasket the machine shop to skim the surfaces true. Working out what thickness you need is the tricky bit

So basically get a thin flange cut then skimmed perfect then use two headgaskets?
IE one either side of flange/decomp plate?

Thin bit of copper sheet and cut yourself a decomp plate.

You could probably just drill material out the piston for an easy fix. It's not gonna make a huge difference to your performance and you can knock off real fine amounts easily.

just bang the boost into a stock motor, compression isn't that high.

I know nothing about this so I may be talking crap. But could you not pocket the piston heads slightly to bring the company down. Kinda like they do with gti ones when fitting big cams. ? If so I'd of thought this would be the easiest way?

Yeah...in basic terms drill a hole.
Talking to Martin from 106moaners he rekons 10-15psi would be fine...dropping comp he said would make it a vitch to start

i think you will be fine just look after it make sure it dont over heat and it keeps all its oil inside the engine and think you will be ok, the reason samass one died so quick he didnt give a shite just max it out and hope for best, if you look after it should be fine

I wouldn't go for lower compression, TUDs are quite low as it is so any less and you'd have starting issues, particularly on veg. Just keep boost low, 10psi should make a huge difference anyway...

That's quite high!!!
But leave it, keep it low boost and it'll be fine...
