got a nova sitting here with a 1.4 engine in it , but no head on it.

allthough exhaust manifold is twin down pipes ? 1.6 ?

but there is no lamba sensor in it ? so was this a carb engine ?
judging by the lack of wiring i guess it was ?

allthough it does seem to have a return fuel pipe ?

update , owner said it was orginally a 1.2 , but it now has a 1.6 single point engine in it ... so that exhaust manifold would make sense being a twin down pipe .. but it must still have been a carb ?

SPI isnt carb, it simply uses one injector effectively to deliver fuel to all cylinders.

but should all spi's have a lamba sensor in the exhaust manifold

No my 1.6i GTE does not have a lambda !

A car should only have a lambda sensor if it was fitted with a CAT, GTE's were pre-cat hence BigStan's reply

SPI is injection, its completely different to a carb, using a vacuum sensor, whereas carb just uses a venturi.
All SPI engines have lambda's.

Think its just e16se(gte) that dont.

Look at the engine code on the block!

GTE's rule... no cat.

Nope, sports rule, no CAT and 40's! Lmao plus cheaper road tax! lol

Thats beacouse you dont have a 88 Nova GSi. you either have an 88 Nova GTE, a 88 Nova converted to GSI spec, or an Opel Corsa A GSi.
