   Right Just Wanting some info really and no I don't want to go 16v.
   
   Just wanting to know how much would be looking to make a high compression engine.
   
   Can I use the 16v high comp pistons?
   
   What else would I need and what sort of gains can I expect?

   lord bedford your best bet is to have a chat with mikol as he has gone about as far as you can go using standard bits and keeping it on the cheap.
   
   But your looking at mk2 98bhp bottom end (pretty much same as jp4) then a complete s1 rallye top end with usual breathing mods get all that done will be around low to high 120bhp ish mark possible to get more if you fettle a bit more

   Sounds good to me..
   
   Is that the dude from 106oc with the white flat arch?
   
   Aslo call me gay but I actually quite like having the 8v it makes me feel like I have balls.
   
   And what's with the lord Bedford?

   I've been looking into the same setup. I messaged Mikol about it. He was very helpful. I have a ported S1 Rallye head and a CatCam 605. Not really sure about the cam as I think it'll only give a tiny gain over the J cam fitted in the Rallye head as standard. I wasn't sure weather to use a 1.6 bottom end or just stick to the standard 1.3 in my Rallye.

   do the flat pistons make a lot of difference?

   Get your self on rallye reg and speak to a guy called tommy something can't quite remember,
   He had quite a high spec 8v,
   16v bottom end with pocketed pistons and a nice cam,
   Sure sandy may of had input or built it but that could be wrong,
   But I remember it making some very nice power!

    Never been too fussed on the "big power" just like a car that was built for the use it gets. Always been interest in high comp engines since I had my first honda.

    1.4/1.6 xsi had oe high comp pistons combines with S1 head and inlet and a Newman ph2 you'd easily have 120bhp

    I ran 8v 1397cc making 140bhp on standard management, would have made more on standalone management.

    Would be interesting to see what some one that knows what they are talking about's opinion on this.

    I did the inlet/bodies and mapping on Tommy's, but the most interesting was Jools, a budget 8v I built with notched standard pistons, Piper cam, head by me, single bodies on custom inlet, showed 170bhp@7500rpm and 127lbft on independent rollers..

    So what sort of figures would I be talking if I build the engine myself with all off the shelf components?

    cheap option is use long black top 1.6 or 1.3 106 rods with thick top pistons such as ax 1.4 gti, 106 1.4 xsi or 1.3 106 rallye. Then cut out to clear valves. though odds of finding all these parts is slim these days.

    Cheers mate I'll start a shopping list. Should be ok for some of the parts on the list as we have 2 specialist French breakers close and are stocked up with ax's and the likes.

    Isnt the xsi 1.6 the same as the s2 rallye engine though with its slightly dished pistons? I thought it was only the 1.4 xsi that got the domed pistons, which are slightly more domed than a 1.3 rallye I believe

    Cheers for that mate it's starting to be a real possibility for a home build.

    That was home build with all second hard parts apart from the cam. just cleaned every thing. no polishing or porting either as cant cos the rules of the race series i am in. Dont use the 90bhp pistons as they dish tomuch. if you use a later 98 with roller rockers but chuck the head. been told ones with z07 in the head castings have better swirl pocketing in them. but mine dont have no fancy air filter either so that would have help.
    i got a different exhaust set to try soon
