What motor for my mk1?

[velly_16v_cab]

2.0 16v all day long......or even a 1.8 16v engine.

failing the above then 2.0 or 1.8 injection 8v's but i would look at 16v if you can.



if money is not a problem then 1.8T or 2.0T or even VR6....how much you wanting to spend?

Thierry and Peter are both right.

In the UK if modifying a Mk1 GTI that already runs kjet, a 16v is relatively easy, as parts are cheap and easy to come by and the car and the engine run the same injection system.

There are bugger all 16v VWs in Australia, so all parts are harder and more expensive to get and kjet is misunderstood and parts are expensive.

There are more and more 20VT cars being wrecked here and so these engines are more plentiful. The ecu and turbo piping and wiring will still cost you, but the car will be quicker and more reliable at the end of it.
It will still cost you $5k - 8k minimum to get a 20VT in your car running.

The budget option is the 2L EFI from a Golf 3, which is cheap and easy. The motor, gearbox and loom will cost you about $1500, which is
Engine $400
Gearbox $700
Factory Loom and ecu $400 or so, or go aftermarket.

Or find a whole smashed Golf 3

Whichever way you go with a late model engine, you will need to do some wiring work to the Golf 1 and probably change the dash to fit in a later cluster.

With my Mk1 Caddy, I have a 2E 2L EFI engine with early 8v GTI 5 speed gearbox, Factory wiring and uncoded ecu. I used the later fusebox from the golf 3 and used the whole loom rom the Golf 3 and just spliced in the Mk1 taillights. I used a Mk2 dash, into which the Mk3 cluster fits. That means you turn the key and the motor thinks its a Mk3, so you get reliaility and the car is light like a Mk1 so you go fast.

If you dont like wiring, get a 1.8L with a big cam and a dirty great webber.

its all about budget really basically how much you willing to spend options are endless set a budget and work from that, but as posted in other posts 2.0l 16v is awesome!! mine runs on the early k - jet (no bull crap emissions) and the roar is awesome ive had 2 evo lancers, turbo swift gti but still the mk1 with the plain old 2.0 16v is more fun!!! my mate runs a seat 2.0l pretty much same as the mk3 2l great setups heaps of fun aswell but has nothing on me in the mountains

How hard is it to find a 2L 16v in australia? I would love to go 16v but it might be a little out of my budget.
Im now thinking of building a hot 2L 8v from a mk3. My girlfriends dad owns a engine shop so most machining and what not i can get done for free.
How strong is the bottom end in one of those motors? Im not going for huge power but want it to be tough. Im thinking standard crank and rods but with arp bolts, with these je pistons http://www.jepistons.com/Products/186240.aspx
Then get the head done, port polish, bigger valves etc. And a good cam.
I was going to use twin webers but if i have enough money left over from the motor i might get injection perfection throttle bodies http://www.injectionperfection.com.a...nt/view/21/71/

...modifying a Mk1 GTI that already runs kjet, a 16v is relatively easy...

Is this because the 16v also requires the Kjet pump/baffled tank/8mm lines?

Or is this because you can hook up the existing Kjet CIS to the 16v and not have to bother with the ECU etc.?

I'd imagine running EFI would be preferrable to mech inj - but does this make the conversion much harder?

I am currently running Kjet CIS in my mk1 (with kjet pump, baffled tank, 8mm lines etc) and have been researching a 2L ABF 16v conversion, is it worth getting the full loom+ECU or keeping the Kjet CIS?

(sorry to hijack the thread, just thought more info could help)

Mk2 GTI 16v was Kjet, so plumbing the system into a Mk1 Kjet GTI was not that hard.

That was however, back in the day when there were plenty of parts and donor cars available in the UK. That is not true down under.

You can run the 16v with basic Kjet, but it wont have vacuum advance and the metering head is not quite the same.

8v Kjet GTI is the most fun IMO. Build a fast 8v motor and hang on for a lot less money and effoirt than a 16v.

I would always go EFI these days as kjet is old and parts are expensive. It does mean completely rewiring the mk1 though.

go 16V you wont regret it....if your doing it yourself could pick a decent one up for $1500 - $2500, not including shipping, lucky to get one with a 5spd if you look around, after market EMS $1000, and the little things like engine mounts driveshafts and stuff like that throw another few hundred on. all done for 4g. smiles all round

Yep, the long standing debate of 8v vs. 16v.. one I have been giving plenty of thought recently... To work your existing 8v or go for a 16v?

Personally, I'm leaning toward the 2L 16v because of the starting 110kw and better efficiency. However, not sure of the legality of a 2L in a car that previously had a 1.6L.. (you can increase size by 25% right? in that case 1.6L X 1.25 = 2L)

You can run the 16v with basic Kjet, but it wont have vacuum advance and the metering head is not quite the same.

Thanks for the advise matt, EFI does seem the better long term 16v solution. As long as you're not put off by the extra work.

Which brings us to the next important point... $$

So you'd be looking at a minimum (If you already have a 020 5psd - less hassle as 020 gearbox fits existing mounting points):
-Motor & ancillaries + ECU + Loom = $2500? (landed in Australia?)
-Another $1000 maybe for misc. conversion costs?

Can anyone confirm (or correct) that?
