A couple of Mk. 2 GTI questions............

[velly_16v_cab]

i really need to change my manifold, still running std RV one

[ozgti]

I have a 16v Magnex exhaust on my gti, will be for sale soon as I'm going back to mildly modified... Sounds awesome, but then again, I have the UK Kjet!!!

So let me get this correct..

If i get a UK MK2 GTI exhaust manifold i can use it here in OZ?(Adelaide)

Even though it has no CAT.

Can some one recommend any other bits from the UK GTI would be worth getting for my OZ MK2 GTI?

Might get myself a shopping list going for my friend who is on his way over with a container.

Supposed to have house stuff but i am sure he could squeeze some parts in for me.

AGG is common Spyda, late model Golf 3s.
The 3A is the 2L Audi engine and is the shortblock 2L. Not very common

Ah ok, my bad. I knew it was somthing like that though.

I have never had clearance problems putting 2Ls into Mk2s.
Mk1s will hit on the bonnet, but Mk2 is sweet.
Even the ABF in my Mk2 was fine.

The Golf 3 Downpipe and manifold is a good upgrade for an Aussie Mk2 as it is freer flowing. It will hit on the subframe and will need a small bit chopped out, unless you are running a taller 2L engine.

The UK GTIs were 110Hp and the Aussie ones are 90Hp. the differences are manifold, cam and valves and ecu.
Aussie intake valves are 32mm UK ones are 38 and South African ones are 40!

I looked up info on the digifart ecu and could find how UK digi2 ones where different to ausi digi2's...or any other digi2 ecu for that matter.

Is the UK head EV? and whats the South African just out of interest?

It seems that alot of power is lost in the difference in the heads. I know that along with other small bold up mods, a worked EV head with intake and exhaust valve size increase to 38/40 makes about 150 at the fly.

I've seen EV's from the UK and South Africa. Do they still have different sized intake valves even though the engine code is the same?

The EV is often referred to as the 'big valve' 1.8 head.

Also in regards to having the cat, it depends on the year of your car. I think if it's post 1988 it needs to (legally) have one??

I've got another question while i'm hijacking... My old grey GTI (UK EV) had an Audi 1.9 bottom end according to the old rebuild receipts. Which block is that??? It went great!

Cheers,

Isn't the Audi a 2E block?

The cat isn't in the fanimold, it's further down stream (well it is in the UK!)

[Golf Loon]

EVs in Australia have the small valves. Jap Spec Engines for Aussie emmissions.

I have put the heads next to each other with a UK import engine and the UK ones are bigger.

The ECUs are also definately different, the UK ones throw more fuel in.
No benefit on an Aussie car without headwork.

1.9 Audi Engine is a SD engine code.

Early Audi 2L is a 3A. The 2E engine is a tall block found in early Golf 3s and SEAT GTIs and is too tall for an Audi.

i thought aussie inlet valves were 35 or 36mm

but yeah, a good cheap quick 8v i would have would entail 3A block, south african head, mk3 twin downpipe, and CIS-E.

2L shortblocks are heaps punchier.

But finding one with low clicks is going to be hard. The AGG engines are only 10 years old, where as the 3A are now 20-25years old.

thanks for the replies guys and the good ideas..........

as I said, I'm new to Mk.2's so are still a bit green.

There seems to be many very experienced people on this Forum!

Sounds like a Mk. 3 manifold and twin down pipes and a new exhaust is a recommended and worthwhile 'cheap' modification to make to an Aussie Mk.2.
(would it be possible to bend the down-pipes slightly rather than cut the sub-frame?)

Any idea where to source a 2nd hand Mk.3 manifold? I guess the down-pipes would have to be 'factory'?

Cheers!

Hey Rosco.

I did this on my Aus spec GTI and it makes a big difference. If you aren't changing the block they you don't have to bend or cut anything. You will need an exhaust guy to make up a plate to match the downpipe to the cat but that cost me $40.

Give Brian at GTI Imports a call, he is in Sydney though.
