both, and in addition because you have changed to FI rather than NASick Puppy wrote:So does it need certing because of the upgrade in power, or simply because the engine type is different?
Substitution of engines
when compared with the OE engine, the replacement engine:•
– is of the same or less cubic capacity, and
– has equal or less weight, and
– has the same or less power output, and
– uses the same fuel (petrol, diesel, LPG, CNG), and
– uses the same unmodified attachment points and system (ie bolts-in), and
– uses the same ancillary equipment (accelerator linkages etc), and
– uses the same family of block and cylinder head from the same vehicle manufacturer, and
– is of the same configuration.
Minor modifications to OE engine
the modifications result in not more than 20% more power than the OE engine, which • may include the fitting of:
– extractor or free-flow exhaust manifolds, or big bore exhaust systems
– changed intake manifolds
– changed or multiple carburettors
– modified fuel injection systems
– changed ignition systems
– alternative cold air box induction systems.
(See • Note 2).
Note 2 LVV certification is always required for the fitting of a supercharger or turbocharger as a modification, or the upgrading of a supercharger, turbo or wastegate, or the re-chipping of electronic engine control units on turbo cars.

And the GTi-16 is the UK version - I did lol at the listing in Identicar about some of them having dual exhausts...1I1 wrote:Nah GTi is the NZ new version
