Coming back to your OP. What is it you want to know / get help with? Seems you've got your stuff together and it is a fact of putting all together again? Or you want to tinker a bit with porting / exhaust / intake / raise compression?
Or you want tips on how to ease the "put it back together" task?

the flywheel im just a bit scared of as its a dual mass, what is the cost of making a new steel one? and how much weight do you think is ideal to shave off?
I don't think it is easy to shave a dual mass flywheel get a solid flywheel. On the (GTV) Busso's many guys suggest to replace the DM with a solid flywheel. At the end you do not really gain BHP it only revs better - so for TLGP or track it makes sence, but for driving briskly through mountain passes it has little effect.

i would love some throttle bodies and i know tony and rory make a epic set for my car but im too afraid to know the cost haha!
You will still need a plenum to make use of the MAF - otherwise you'll need a different ECU. Modifying the plenum will have a better price / benefit.

knife edge the crank counter weights, replace the alunimium crank plugs with grub screws then have the whole assembly, with front pully and pressure plate fitted, dynamicaly balanced. Makes a big difference to driveability.
Knife edging helps: less drag through oil = less losses.
:thumbs: on balancing. Before assembly - Balance all your components to equal weights: get a digital kitchen scale and get all the pistons as close together in weight as possible - sand/file on the inside of piston - same with conrods. Then match up a + weighted piston to a - weighted gudgeon pin and conrod so the combination is close to each other.

Flywheel: ok if im not having the dual mass then where can someone make me a single mass flywheel then? or even better where can i buy one?

also, isnt the dual mass to dampen the vibrations or can the experienced say otherwise?
Yes DMF is to dampen vibrations. But then that gearbox is designed to be used with other engines, including diesels - never take a DMF off a diesel. If you are balancing the motor - and it is a petrol V6 not a diesel inline 4 - so your vibrations will be negligible.

For the Busso engine range, you could just use the 2.5V6 flywheel as it is the lightest of the range and will work on all. For the GM based clutch - I don't think there is off-the-shelf alternatives - ask Hennie where to have it made.

I read the Brera uses the GM F40 gearbox - here is a SMF conversion kit for that gearbox: http://www.ebay.co.uk/itm/VAUXHALL-...arts_Vehicles_CarParts_SM&hash=item3cc770e833

Here is a picture of the DMF from the top and an indication of how much i am going to take off from it:

Secondly.

DMF bottom half

Here are some pics indicating on how i plan on grinding the bottom half sides off the DMF

now i dont think this will shave off like 5kgs but im hoping to get close to atleast taking one kg off, in terms of spinning force 1kg can be a lot!

it probably wont make an outrageous difference but maybe give it just a liiitle bit more zing.

So what do you guys think? i know its not ideal but the VAG and BMW guys actually pull this move off so... its better than not doing anything to it at all.
How much does the whole thing weigh - what's your starting point?

I think you can get more thatn 1kg off. I think you can go more aggressive on the grind down - I say take it to an engineering shop.
