hi all i am new here, i have got a poorly s1 and could do with a new head does anyone know if s1 and s2 heads are the same ? as s2 heads seem to be easyer to get hold of thanks lee

 

i think so

 

hi,now i may be wrong here, but iv always thought the xr3i head will fit an rs turbo. correct me if im wrong guys!!!

 

yes they are the same but the exhaust ports are round on the S1 head but makes no difference

 

the heads are the same , wot seems to be the proplem with your head ther gone realy go wrong

 

Hi it has had a big valve convertion to 45mm inlets allso a stage 3 port and polish and has cracked between all 8 valves it also has a very large hole on piston no 4 and had just sent the haed off to be checked before i put it back together.so i have hit another obsticle.

so a series 2 head should go straight on no messing ?

 

Yes mate will bolt straight on

 

i have got a spare s1 head if you need 1 its has only done a gen 32k

 

i think i have found one but how much do you want for it ?

 

s1 and s2 heads are the same as far as fitment goes but you should be aware that the s1 head has softer valve seats as it was from 1986 that they made them unleaded so a very early head may need new valve seats to use unleaded.
i would get a s2 head if i was you

 

50 nicker plus postage my friend

 

Get any 1.6 mfi CVH head, they all the same, but use your old cam, pulley and valves
Also I'm with mikedaf2 he's right about late heads... better get one from MKIV 86-89 car
