What a difference!

I know its been done to death Andrew but would you recommend going to 4+ without forging. I only give it a little push here and then. But I suppose just doing that could damage it...mmm
I don't think anyone would 'recommend' going to 4+ without forging...but if the question is "do you think I'll do any damage if I drive it with a bit of respect?" then my answer is "you'll probably be fine".

The thing is, 'probably' didn't feel right to me, so I forged anyway.

I'm sure you've already seen the photos of my standard pistons - they were in perfect condition, but with a reasonable amount of carbon deposit. I reckon the carbon would have burnt off if I'd given it more of a push from time to time - but without forging, I didn't feel confident in its ability not to go pop. So I drove with care and had the occasional short blast...which really defeats the object of having more power.

Here's the piston before and after toothbrushing the carbon off.

Full fat 4+ with injectors, pump, plugs, breather, meth and forging has set me back about £6,000. There is a big difference between 4 and 4+ (the torque is huge) but Stage 4 is a brilliant place to get to. You just need to ignore the voices that tell you to keep upgrading :laughing:

What's the cost for just Forging mate? If you don't mind me asking.

I'm at revo4 and debating on going 4+.
You'd have to shop around, but the going rate seems to be around £2,400 - including oil, coolant, ac recharge, gaskets, timing belt etc.

I'm sticking with Revo and SCC for tuning, but I opted for a Mountune forged build at their Essex HQ for a number of reasons.

The price is £2,999 (although there was a deal on the pistons and I paid £2,845 including a second oil and filter change). They did an absolutely first class job and the car is smoother than OEM with no clue that it's been forged. Just what I wanted :nice:
