im currently doing a clio williams turbo conversion for my R5gtt, just wondering what i should do about pistions, should i get mine machined down? if so by how much and what boost could i run? or should i get forged low comps and what boost could i run before having to change to forged rods?
where can i get a turbo manifolld from? BB tuning do 1 for £300 is there anywhere cheaper?

you pay for what you get...the cheap £300 price tag reflects a poor manifold.

what power are you aiming for?

i was looking 4 around 250bhp, is this a realistic figure? that power have other people been able to get?

You can`t get standard pistions macheined down. You have to put in thicker head gasket for lowering comp ratio.

i emailed bbtuning about how much boost ther head gasket can take and they emailed me back saying that i need to get 1mm machined off my pistions bringing the C/R down to 9.0:1?

ahh the effective way to a crap car, increase the squish clearence.

Run the standard set up, don't kill the cars driveability by increasign the squish to reduce the cr.

low cr cars are crap.

I know stan, I'm a muppet.

40PSI on my T2 with no intercooling cos then its already, like on fire, and like it will give it even more power and wild cams, they say it just makes the mixture go out the exhaust, but thats liek my afterburner for more thrust.
