Paul,
They're only made in a 1.8 version, in either black or white coachwork. Mine's black.
Maybe you're getting mixed up with the Civic VTi, whch comes in 1.6 or 1.8 with 3 or 5 doors.
The Integra shares it's engine with the 1.8 Civic VTi, the Civic has 169bhp, the Integra has 180bhp as it's much lighter and nimbler - the 5 door Civic is a Rover 400 clone!
The engine is unblevably strong and will go past 9500rpm, at which it sounds glorious, but worrying. If you'rr seriously thinking of buying one, you can kiss the neck end of £10k goodbye (dealer price - if you can find one) and your insurance will be pricey. I'm paying just under £600 with 12 years NCB for a protected policy.
It's not too bad on gas, but when you start to use the V-tech cam, it will start to guzzle. They look exactly like they are, so get a good alarm fitted and some strong secondary deadlocks.
Honda dealers are expensive, but they treat you well and courteously, unlike Fiat dealers who are shite in just about every department.
One thing to think of, is the red key - just like Fiats, but you only need it to clone duplicates; not for the ECU.
