Now that my engine will be coming to pieces im considering getting some general headwork done by the local head specialist. I remember seeing in the old forum a post about headwork and about 3angle valve seats etc. Im fairly clueless about this kina stuff and with no coupe specialists in NI its difficult. Can anyone tell me the what i should be looking to get done? or wat the coupe responds better too? Was just thinking about a General Port, Polish and getting the manifold matched? Iain

I was worried about this, ive been considering a few things now the engine will be coming apart like headwork, lightened flywheels etc. but ive been warned that with both these, although the power output will be up the driveability and some torque could be lost?

Id go for forged internals and gapless rings on my next rebuild and if i were in your position with the cash forged bits are best. balance them all up as well adn teh rods if possible and get the flywheel done as well and it will make pickup better adn teh car should feel a bit happier to rev off boost as well and beign forged they will be stronger and hapy to rev freely so come remap time with it all done right the rev limit can be raised as well

Well its getting rebuilt anyways, so i was speaking to barbz he reckons that with the GT28R running 1.5bar midrange isnt a problem on forged internals... also they are a much better design, with gapless ringlands and coated tails.

How much is it for the pistons and rings? What about balancing them or that going to be done when they are on the rods and the flywheel done?

Thats what im thinking... im considering buying a complete engine fromo barbz built with Forged pistons, balanced rods & and Performance head then get it live mapped for 1.4bar which im sure shouldnt cause any problems day in day out.
Ive basically got used to the idea that the car will be off the road all winter now anyways.

The pistons & rings are about £750
I had planned to just get the rods balanced by barbz and get him to build me up and engine and send it over to me, it all depends on the final price tho.

I have balanced pistons and rods, gapped down piston rings, fully ported and polished cylinder head and balanced and lightened flywheel. Works well for me.

on a sidenote, I inspected my pistons last week, all the ringlands were showing signs of fatigue cracking / maybe light det, but ALL were pretty much fooked, oddly enough, the tops of the crowns were clean, yet the head was WELL coked up the rings looked in good nick, essentially, if you are to go for big power, get forged, the OEM stuff is so poorly balanced its horrific

Is this what actually causes the pistons rings to fail? the fact they are badly balanced?

Yeh. As im not planning on changing my turbo anytime soon im sticking with that. Engine was supplied by barbz, fitted my own flywheel and clutch and turbo etc. Just the basic block from Barbz.
An engine delivered on a pallet to glasgow was £60. So maybe not as much as you think?

This is something barbz said to me. I dont have the balancer shaft anymore cause they are balanced.
