the genesis (if its 1.3) will be single point injection and 55bhp i would have thought whereas the gt will be multipoint injection and 75bhp...go GT

I did once go to view a 1.3 Genesis, which had the GT engine in.

They guy selling told me that was the original engine for that car

Might have been an NZ engine, they look the same.

I've seen a black K plate Genesis with an NZ engine.

my polo is an L reg genesis 1272 ive had two of them but they both been single point fuel inection, some genesis polo's have the multipoint fuel injection but ive only seen it in the squareback shape which say Genesis Catalyst on the back.
does anyone know if the gearboxes are different (GT - Genesis)
(Cams Cylinder heads) are there any differences?
wiring looms are they different? does the whole lot have to be swapped over if you either do an engine swap or just the fuel injection system? i could go on for ages lol
cheers for the help though fellers!
P.S how do i get a pic of me darkhorse motor onto the site or signature?

The Genesis will be an AAV-code SPI 55bhp 1272cc motor, with a 9.5:1 compression ratio, mild cam (204 degrees) and the same cylinder head and port/valve sizes as a GT. It'll more than likely use the 8P gearbox - which is quite high ratios compared to a GT.

The 3F GT is MPI 75bhp 1272cc, with 10:1 compression ratio, slightly hotter cam (219 degrees) and a close ratio gearbox.

The wiring looms are different on account of the different injection systems.

Thats the kinda sh*t im tryin to find out!!! cheers mate! Can you just swap the heads over do you know? you see my genesis engine is knocking its balls off (bottom end going big time) just waitin for the conrods to come flying out the case lol.
the GT engine i have was known to be smokin the last time it was running, so looking to try and somehow bodge meself a half decent sowin machine out the lot!

Just entered the reg of the Genesis I knew into RAC.

Manufacturer Volkswagen
Model POLO COUPE GENESIS
Body type coupe
Colour Black
Fuel type Petrol
Date manufactured 30 December 1992
Number of previous owners 3
Last owner change 20 September 2004

K335 MEJ if you want to look it up.

Definately had an NZ engine as I remember looking it up on his boot sticker.

Probably old stock left over from 1991.

its probably just an engine that was left over from old stock. They used NZ engines in mk2 golfs you see so when the golfs stopped being made maybe they had a few spare so they ended up in a load of polos.

Yeah my parents used to have an NZ Golf, pitty I chose red (fadded really quickly), but then again I was only 7 or 8 (if that) at the time.

The heads can be swapped over - but obviously use the GT cam in the Genesis head if you're putting it on the GT.

Cheers for this info mate! will i have to swap all the valve springs and what ava ya from the GT head to the genesis head when i swap the cam or are they the same?

amstrange1 · Post by **amstrange1** » Fri Mar 18, 2005 12:16 am

Just whack the cam in. If you're feeling keen you could put new hydraulic tappets in though.
