nothing, hence zvh
its the z part of the equation which needs to be modded as its designed for a 16v head.
there are however some mods you can do to improve the design. For example welding the back of head so it increases the surface area which meets the block. This will allow you to fit zetec gaskets or more importantly the rs gasket. What I have done is left the head alone and not welded it as I did not want to have it skimmed which would affect the CR, so after some discussions with Simon at Sitech he supplied a custom 3 layer metal head gasket which is much stronger than the alternatives and can handle as much boost as you can throw at it, and the mega plus side of this gasket is that it is re-usable.
Hope this helps mate

yes, his are custom made and I know he has just restocked recently unless they have been sold. The headbolts im using are again Sitech spec re-usable ones.
for the prices you need to speak direct to Simon for exact amounts, you can get him on 01796 481 495, i would recommend giving him a call as he will answer all your questions in a matter of minutes![Smile](https://passionford.com/forum/images/smilies/icon_smile.gif)
Hope this helps mate

aiming for a safe 180-200bhp.
i dont want to go into efi as i have no clue with electrics and knowing me if i had a go at it my rs would proberbly never see the road again .![Surprised](https://passionford.com/forum/images/smilies/bigcry.gif)
but as it stands im wanting to change the following
-lifters as they are noisy
-cam belt kit as no proof came with it to show that it had been done
-water pump so i know that has been done
so i thort i might as well do a rebuild so i can see what pistons are in the 2.0 bottem end as i have been asked what it has in and again i have no clue
so with a safe 180-200bhp MFI in mind im wanting to do the following and keeping in mind im new to this so please help if i need it and put me on the right tracks![Red Faced](https://passionford.com/forum/images/smilies/icon_redface.gif)
-burton cam and vernia
-c20let pistons? (been recomended to me but i want more info about this beeing true)
-uprated headgasget and bolts now i know it dont have to be welded
-and a 195 chip ?????
-recon my t3
-pace intercooler on it at the mo what will be staying
-and a good clutch

well I would say look into efi more, its not as daunting as you think!!
Jamsport/sitech can sort you a gotech ecu and all ancilliaries for a pretty much bolt on kit, the crank signal is picked up from the dizzy and the only other mod really is the injector rail is machined open to allow fitment of electronic pulse injectors.
Pistons, im using accralite low comp pistons in mine, it used to have c20let pistons in the old block but I binned that so I could start a fresh. Pec have some great deals on both rods and piston packages although they deal with wossner pistons which are also a good make
as for 200bhp, i think you will struggle for reliability due to the nature of the metering head, sure a lot of people will say it will do the job but remember it must be in tip top condition which is a rare think. I have a 1900 tall block which was maxing out at 190bhp and had to be dropped to 180 to be safe, this was a stage 3 engine but with mfi.
Your 2.0 block will require a lot of air to work properly which in turn requires fuel, this will be your limiting factor. ( I asume you will bin the pace.lol)
Ive just got a newmans with solids, solids by there nature tend to sound louder than hydraulics (so im told, not fitted mine as of yet)

of course you can, like I say the only serious mod is to the mfi injector plate, feel free to give me a call and I can explain the above much clearer as ive done a lot of research into this, it doesnt have to be expensive. Just needs the right planning and correct build order
