Golf GTI Mk2

[GOLFBALLS]

The head of the aussi model is identical with the european spec cars. I've put them side by side and measured them. Zero difference.

Hey moto, my old mk2 GTI was an ex UK k-jet with the EV 8 valve engine. It went MUCH harder than my current Aussie spec RV car.
The head on the EV engine does have bigger valves than the RV but i don't know about other eng codes??
But you are totally spot on with thrashing the car to make it go better.
My Aus GTI used to sputter and carry on anywhere over 3500rpm. One day after driving my boss' Cordoba which absolutely flew, he told me it goes well coz he thrashed it on a daily basis. So, I decided it was time to show my GTI who was boss and i drove the tits off it for a month!
Now it goes better More power, better fuel econ, and no sign of coughing even up to 6200rpm.

As far as exhaust goes, if you spend $400 on a Jetex system from the cat back, its not going to do much apart from make lots of noise. You can get noise for $250.
Do it right and replace the downpipe with your $400. Changing to a high flow cat wont hurt either if you have some extra cash. Thats where the most of the restriction is.
Hope that helps.
Cheers,
Wade

Yeah I agree with Wade Moto.
Kjet UK heads definately have much bigger valves and go much harder.

Can anyone display this using ETKA,
otherwise it is just hersay, as we keep going on about how terrible an Australian car is but no one has any proof to back up their retoric
Its like people on this forum crapping on about the ECU being different to one in sunny old pommy land, which has been proven to be a complete load of bollocks
Just because someone drops in from another country does'nt mean that they know what they are talking about

Given that mk2 1.8L engine range from 85-115hp there has to be head difference between engines. The RV is rated at 100hp according to the Bentley, not sure if the US got the exhaust system we did on this engine though but i'm pretty sure they had cats given California is hard on emissions.

Here we go just found valve diameters in the Bentley, HT, RD, RV and PF have 40mm intake 33mm exhaust all of which have 100hp where as the GX and MZ engines have 38mm and 33mm with 85hp and 90hp. Keep in mind the Bentley only seem to show US engines but it's a start.

So does this mean that an RV head has big valves?

It has normal valves in comparison to some US engines, the Euro engines could be different again though as some have upto 115hp where as the RV has 100, bigger valves, no cat and the dual pipe downpipe would equate for this.

Thanks mate, sounds like clear info there
I agree that the D/P & cat would make up the difference, it seems logical.

I`ll take a pic of the two kinds of heads Ian

There are 3 kinds. The p*ss weak aussie ones with the tiny valves, the larger head ones as found on US cars and digi Mk2s in the UK and the big manly Kjet valves as found on the first (and best) Mk2s.

ECU is definately different too.

If you plug a pommie ecu into a standard aussie RV engine, it overfuels. If you put it into a worked motor with a big valve head and good downpipe, you are flying.

The ECU is not any different in any to any other all over the world

I really thought that we were getting over all of this stupid & unfounded immature rubbish that people go on about with these cars.
There have recently been posts on this thread that basically state that the Australian cars have a hell of a lot offer that a UK car simply cannot & this is by an Australian person who lives in the UK, who more or less stated that we have a really good car here so make the most out of it
Most of the UK cars are just piles of rust these days, unless you want to pay serious money
In relation to Kjet & digi, well if your tool who drives around playing boy racer at the traffic lights then you will like Kjet, but at the end of the day digi is a way better package for reliability & top end driving as on a HWY or even up hills
I can say this as I drove a mk1 for years with an EV engine running Kjet in it, that was installed by Wolfsburg Motors in St Peters. So it did run to its full potential, so therefore or I am in a position to compare

This is wrong is so many ways that I`m not even going to waste my time commenting.

Speechless.
