definately not worth the hassle. you'll only get 5bhp more than you have now!! your's is a 1.3 isnt it? even if yours is a 1.0 its still not worth the hassle.

star m8, yer its a 1.3 Multi-point, I'm guna modify the cold air intake then, make it a little bigger, I don't really want the car to make that much noise. Although the zaust looks rubbish.

Haynes manual is sucha a load of tripe sometimes,
AAU - 1043 cc single point injection
AAV - 1272 cc single-point injection
3F - 1272 cc multipoint injection (im guessing this is the GT then)
PY - 1272 cc multipoint supercharged

not very... comprehensive r they?
or just wrong?
52bhp for the single point, Im guessing (and hoping ive got more than that :cry:

AAU has 40bhp (or was it 45??)
AAV and NZ have both 55bhp
3f has 75 hbp
PY has 112bhp

the 1.4l engines (from 6n to 9n) are available from 60 tot 125bhp (8v and 16v versions and also mpi or singlepoint versions)

So why did they have both the single and multi-point versions if they had the smae horsepower? Economy? Reliability?

Insiders at VW say that the NZ was to close to the 3F, in the lower rpm region the NZ is even a bit more powerfull than a 3f.
So VW replaced the NZ with the AAV in te polo mk3 series.
And the AAV was a cheaper build engine.
Other thing mabye, I'm not sure, The AAV engine runs a bit cleaner (NOx CO values) due betters electronics, The NZ runs with less electronics.

edit:

I mean with electronics mainly the ECU :)
The AAV runs with everything controlled by the ECU (ignitiontimings, fuell amount and injection timings)
The NZ uses some more "old fashion" ways to control some of these things. Not by ECU but by (not sure about the correct word) under or low pressure units, it will mechanical set the ignition timings.

What would anyone suggest I do to my engine, to keep it quiet... Street sleeper if you like, I'd just liketo have taken that rover 25 the other day...

Just thinkin' The diesel engines mostly have an isolation package under the bonnet, maybe that's an option :D

The NZ and 3F engines look VERY similar, the garage where I have my car serviced has an office opposite and one of the people who works there has an NZ engined black Genesis. His engine looks the same as mine pretty much, it's even running my old Pipercross!

AAU - 45hp, 55lbft (probably cracking on for 50 without cat)
AAV - 55hp, 68? lbft <-- cant remember and am lazy (ditto 60)
3F - 75hp, 70-ish lbft (more of a top end power than an all round torque boost from the mpi conversion - still its more punchy for all figures and has very similar economy)
G40 - 118hp, 90-something lbft

it does actually say these figures in the haynes manual (as well as the polo owners handbook) but you have to fish for them. they're a bit slack on consistency.

the 40 and 50hp engines were the old carb ones from the 80s, 998 and 1108cc instead of 1043 and 1275.

Dunno about the NZ ;)


Sad to hear about being 0wn3d by the rover - hope it was a high powered one at least to save face. The figures look good on their engines, but they're high geared (1st is like an extra 33% on my 4spd - can hit >40mph with a similar limiter) - but close, mind you, 4th isnt actually that different - and heavy. Mum's 1.4 could of course whip me any day, but still seems to be badly lacking in the hill climb dept, so you have to cane it to get any acceleration.. (yep, the exact same 1.4 that's used in the MG without even so much as a turbo. Are those hot hatches or warm??).
