Right, i want to keep my pinto for few more years before i decide to change it to either bike or duratec engine.
At the moment ,im running zx9 carbs wiyh megajolt and fr32 cam, what can i do next , i dont want to spend loads of money on the engine, just a bit to
see some more horses, would be nice .
I had considered cosworth head , but cost would be to high compered to bike fittment.
Any ideas fellas.
Brad.
Nitrous Oxide !! mmwahahaha 
30hp nos kit if you dont like it you can get a good chunk of the money back or keep it for future cars ,had mine for a few years now but its a plate type so only for single carb systems
Big valve heads come up regularly on ebay, often fitted with a wilder cam too. Should give you a reasonable power increase if you just want something
to bolt on.
Or you could run it on C-12

Hi Brad what about having the head planed by 1mm it will help on the compression

Ok Graham, could fit a thinner head gasket, but what of these secret mods, Graham.:
would a slight increase in compresion make much of a difrence.
I guess that means yes.
How about a head plane re bore power max pistons bike carbs light fly wheel better oil pump all balanced and put together by me + r roaded by
bogg brothers
ps and a 285 piper cam

That would cost a bit.
I think he wants 200BHP for 200p
Mini Supercharger maybe?
with nitrous dont forget the cost of actually filling the bloody tank, cant be cheap!
the most significant effect you can have for now would be to fit a zx9 or blade engine, could be in for under a grand on the cheap, and would have a
diabolical effect on performance. Any money you spend on the pinto is going to be absolutely minimal difference compared to this. I appreciate you say
you dont want to change engine, but thought id mention it anyway - to me it seems the most cost effective solution
If you're gonna skim the head, make sure you check (if you have a slighly wilder cam) that you valves won't try poking holes in pistons.
A friend of a friend had the head of his ZZR1100 done and reckons it's made one hell of a difference.

Increasing the CR from 9 to 10 ups the theoretical efficiency from 58,5 to 60,2%.
All other things being equal, this would mean you'd get 2,9% more power.
(theoretical max engine efficiency = 1-(CR^(1-kappa)) in which kappa is around 1,4)
However, since the engine is probably already running at BLD (borderline detonation) at lower RPM, you'll only see this increase at higher (3500+
at a guess...) engine speeds.
I've lately been thinking about turbocharging the pinto. Using a small (no big power, 180 bhp would easily be enough) turbo, water cooled
intercooler mounted behind the head and into my modified injection plenum (which has the inlet at the rear, hence the intercooler position).
Properly set up, this should be driveable, and deliver loads of torque and power for little money. There would be "some" fabrication involve
though....

Thank's chap's, gives me somathing to think about.

You mentioned a cosworth head, will it bolt straight on to a pinto block and run?
sounds like less work to get a cosworth engine and run it normally aspirated after skimming the head.
I'll check the book out.
How about 2.1 short engine kit from vulcan £499 ? seems quite reasonable for the money,skim/port the head when you change.
