G20 Junior, Power output of 1.4 zetec se
Discussion
we recently bought a g20 junior (irish-cup) coupé fitted with the original ginetta(still sealed) 1.4 zetec se engine (full alloy) running on the original DAT ECU. mapping is correct.
the engine should develop around 90-100 horsepower.
we drove it last weekend the first time on the track. poweroutput was a bit disapointing....it felt quite feeble.
on the other side: 90horses are not that much.
are we too critical or are those the facts?
engine-upgrade wont be a problem as we still have some budget left and we do not need to keep this engine for race regulations.
would a duratec be a straight fit? i mean enginemounts, bellhousing?

We run a G20 senior car (no roof).
The car is quite heavy, fibreglass isn't light stuff and there's a lot of it, especially in the coupe. One thing I've noticed racing a Westfield with similar power this year is how much later I can brake thanks to the lower weight.
Sadly the Duratec is a completely different engine (not a simple swap) and would need a new bellhousing, exhaust and bodywork mods to suit (exits opposite side), all pipework re-routing and much more besides.
However a Zetec from a Focus ST170 drops straight in and bolts up to the existing gearbox - it transformed our car (which was already more powerful than yours) into something with a reasonable power to weight (we see 185bhp with the original throttle bodies, mapping and a new exhaust). Total cost was about £1500 for the engine, exhaust and mapping.
I can guarantee the Sierra diff won't last long though (we've replaced ours with a Quaife).

not correct:
the ST170 engine has the exhaust on passenger side and inlet on driver side (RWD, UK-car)
the 1.4L fully allyo zetec Se engine has the exhaust on the driver side and inlet on the passenger side...the same as a 2.0 litre ford HE Duratec
the ST170 engine has the exhaust on passenger side and inlet on driver side (RWD, UK-car)
the 1.4L fully allyo zetec Se engine has the exhaust on the driver side and inlet on the passenger side...the same as a 2.0 litre ford HE Duratec

Then my apologies - I thought all Zetecs were the other way round.the ST170 engine has the exhaust on passenger side and inlet on driver side (RWD, UK-car)

That's what happens when you assume!
I suspect bellhousing is the sticking point, but a gearbox from an MX5 would sort that....
