I have a couple of questions concerning your setup, because I have a nearly similar one.
Slight differences are:
130TC intake camshaft
Ported/Polished head and OE waffle manifold
OE cast exhaust manifold
How far does this engine rev?
According to the Guy Croft Workshop Manual "Modifying & Tuning Fiat / Lancia Twincam Engines" ; Standard engine / cast pistons Max rpm : 7,200 , but I dont know if this is max safe rpm !!!
What fuel pump are you using?
I haven't bought fuel pump yet but according to the Guy Croft Workshop manual again, I will buy "Facet Silver Top" electric fuel pump

nice to see you here again and best wishes with your new firm - and - 131 restoration/Gp4 conversion (much more important..!)
Thank you for your wishes and warm welcome Guy
- Fiat 131 2.0 TC
- Engine Overhauled, Rebored (very carefully and clean built) new oil / water pump, new valves and it has fitted 85mm 1.6 dome pistons (9.8 / 1 or 10/1 CR ?) well-done - it will be probably about 10.2/1
I dont know head swept size but I also thought that Cr is not less than 9.6/1 in any case, hope CR is not too high because highest gas octane is 98 in Northern Cyprus, by the way you can have 100 and 100+ options in South Cyprus
- 4-1 Header exhaust (4 equal length primary goes in one larger pipe)
- Hörmann intake manifold and dual Weber 40 IDF
Lightened flywheel according to your specs - hope you got the crank FW assy balanced.....!
standard cylinder head valves and camshafts
This spec, 40 carbs with 34mm chokes (I would not go bigger although 36mm are aval) will take her to about 124bhp.
is this bhp figure at flywheel? (Ihope it is) by the way I dont know why I worry about bhp, torque figure is much important
GC spec valve/seat work and gasflowing would take her to nearer 140bhp. The exhaust on the engine you have now might contribute to a higher figure than 122bhp but the standard cams are so mild that you won't really see much gain from the header unless you change the cams and if you do let me know your thoughts before you buy - cams completely alter the torque characteristic.
Hope this helps some. I should like to see a full-spec StIII motor in that car, GC of course!
I wish I could afford GC StIII engine, I think my only option will be GC StIII Cylinder head. (All the power is at the head :)
If I understand right you are in Kyrenia - beautiful place, post some photos here would you? I miss Cyprus very much.
Hey Guy, you should visit Cyprus again. There is no war since 1974 and you can visit all part of island when you pass from checkpoints / borders.
