Now that my engine will be coming to pieces im considering getting some general headwork done by the local head specialist. <img src="/forum/images/graemlins/wink.gif" alt="" /> <img src="/forum/images/graemlins/wink.gif" alt="" /> <img src="/forum/images/graemlins/laugh.gif" alt="" />

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

Speak to barbz.

Ross

Didnt you get some work done on your head Ross?

What did they do on your car?

Iain

Barbz done it to be honest. Not sure of what was done. But i know its frigging good and worth the money. Phone barbz i tell yee!! <img src="/forum/images/graemlins/laugh.gif" alt="" />

Ross

phoned him... head exchange for a tuned head with 3angles seats etc £880

Iain

Im not sh*tting it when i say its worth it. Check my torque graphs.

Ross

must do! <img src="/forum/images/graemlins/smile.gif" alt="" />

Check the show your graphs thread in tuning.

Ross

Guy Croft is another place to try, speak to begbie but for headwork im sure nigel said its not hit and miss but sacrifice low down for high up and such like..

Check my graphs. Look at jimbos and phils in comparison.

Ross

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?

Iain

You're not running a hybrid though are you so perhaps not great to compare??

Im running a GT28R.. not sure how this would effects things <img src="/forum/images/graemlins/crazy.gif" alt="" />

Same turbo im running. Im not gonna say more than, get it from barbz. End of.

Ross

Lotta Cash for a head when your considering spending on forged pistons & Balanced Rods at the same time on a part time job wage! lol

Forged internals? planning on over 350bhp? Or high boost?

Ross

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 <img src="/forum/images/graemlins/smile.gif" alt="" />

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.

Iain

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.

ooo id love the delivery bill for that little lot to NI!!! Id help if i were over in the next few months with delivery of bits but im not over till next easter now i reckon <img src="/forum/images/graemlins/frown.gif" alt="" />

As Ross and all say, give him your budget and what youd like to do and can do solo and he will reccomend the best for you <img src="/forum/images/graemlins/smile.gif" alt="" />

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.

Ross

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 <img src="/forum/images/graemlins/mad.gif" alt="" />

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 <img src="/forum/images/graemlins/frown.gif" alt="" />

and barbz did all your work did he ross?

I think he is the man for the job.. even tho the delivery on the engine will be hidious!

so is it just balanced standard pistons you are running ross? and balanced standard rods?

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

Iain

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?

Ross

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

Ross

its sounding better by the minute infact!

Will make some more investigations tomoro, friends of my families that work in haulage company (woodsides) that could prob do me a decent deal on bringing it to their yard in NI.

Looking more interesting everymin <img src="/forum/images/graemlins/smile.gif" alt="" />

Iain

Thought about getting your car shipped to barbz?
