VW MK3 GOLF 8V TO 16V CONVERSION

[golf3]

Hey guys,
I have begun the conversion...

I am taking out a 2.0L 8v multi-point injection 85kw motor, and installing a 2.0L 16v ABF multi-point injection 110kw motor and a stronger gearbox...

First of all, my reasons for starting the project

It's known as a crumble box or 020
Suprisingly, it still drives!
And goes clunk clunk...

So, i bought this...

THANKS CARL!

and the important DUAL CAMSHAFTS!


ANd the work begins...





AND MY ASSISTANTS!
THANKS!
(and the crate it came in....)

Hey sean - sorry forgot to reply to your last IM about the clutch parts Those prices are crazy, though :!: :!:

Anyway, on a more positive note, that throttle body in the picture has the Digi 3.1 TPS, so it won't have an immobiliser, which makes things a LOT easier.

Goodluck with it

[golf3]

Yeah, its from an early mk3 gti...if it did have digi 3.2 i'd have to have the key and transponder thing, or go aftermarket...motec..hehehe...

Otherwise, Carl provided a full gasket kit with it, which means that when i do the head gasket, i'll get the head crack tested and then ported and polished...
But because that will happen before it gets running, then i won't be able to do a before and after power test...

Other mods will be the BMC CDA airbox i already have. Catch can to remove the PCV oil going into the intake, i hate that build up!! And the exhaust will need to be redone as the baffles in my DTM style muffler are broken...

And when it is running, i will want new cams...

But the question is....Would there be any performance gains in getting new valves and valve springs while i do the head

Not unless you move up to bigger valves. I did this on my last ABF - it cost so much that I had to sell the car soon afterwards, though The performance gain is massive, though :twisted:

The ABF lifters from the SEAT dealer are $450 on their own... so by the time you add new springs, retainers, guides and stem seals, the bill gets pretty huge - that's without the charges for the port work

It's far cheaper and easier to buy an exchange head from one of the Euro or US tuners if you intend to get one rebuilt and ported

I've read heaps of times that running cams with the stock ABF management throws the lambda reading up sh-t creek. There are a lot of people running a 260 or 268 inlet cam and a stock exhaust cam, so as to keep the exhaust flow down.

Probably not worth it in the scheme of things. You need big money to get the real gains. The headwork is definately worth it, though

[golf3]

So, I can get the head ported and polished, AND retain the current valves and valve springs...

I have a friend that got his head crack tested, then polished, probably ported for $400...

I'm just loving having 2 camshafts!

Yep, you can reuse them, provided they're in good nick. The valve springs are tough as hell too

400 bucks is pretty damn cheap

Man...n ur old motor is even only how many km?! i hope i had the equipment, time n money to do a conversion. mines kinda tired now

[golf3]

My "old" motor has 86,000kms...
My parents bought the car NEW!

[SOHC]

yep i did remember u mentioned bout that , normally how many k's the engine would stand?? mines 175000 already

[WABIT]

farrrrrrrrrrrrrrrrrrrrrrrrrrrr man your really doing it

good on ya

wabit

wooo awesome Sean!
Sorry i snobbed u guys yesterday! Ive been busy with other crap.
Thats an awesome garage u got going there! soooo jealous! Ill have to come check it out soon.

[golf3]

I went back this evening to do some more stuff...

Only removed the repaired aluminium sump on the 16v, and managed to crack the sump plug. It was on really really tight!!! So, instead of taking the sump off my 8v, i can still use this one...

And i took the old 020 gearbox off the 8v motor aswell and i found another big hole in the bellhousing and the broken rivets...

I tried to pry apart the gearbox casing to see more, but i gave up...
I will source another bell housing half and repair the rivets to bolts...
But if that happens, then that stuff will probably go in a mk1 or something...NEXT PROJECT..hahaha :twisted: :twisted: :twisted:


The clutch is rooted on the 16v, so i'll need a new one of those...

And the spark plug leads have a gash in one of them, so i'll need to get some new leads too..

[GoLfMan]

awesome!!!
watcha gunna do with the old 2L???
keep the fotos coming :twisted:

[Golf Loon]

Glad you are posting these details on here too and that someone bought that abf engine.

Looks good so far.

I`d defo do it in two stages though. Bang the motor in and get it running then when you need more power take the head off, port and polish and maybe cams then put it back in.

Keep us posted.
