tried to start it this morning then it just exploded, the cam belt jumped off the pulley and the valve stems are dead, loads of smoke came out the back.
it was a 1.6 driver with 8v gti camshaft, weber carb, straight through auto. was thinking of converting it to manual but cannot be bothered as the golf is more of a cruiser with the bass and drop etc so auto is nice.
i am thinking its a shame to scrap the car because its so mint, so i am thinking throwing a 1.8 8v driver engine in here with the 1.6 auto box etc, use my weber and 8v camshaft and get a new manifold. I want a cheap fix and i want to start like within 2-3 days time.
suggestions and queries will be most usefull.

From the pic in the sig it does look too nice to break.
This is just a suggestion, i don't know if it is advisable or if it would even go together but how about a mk2 gti head and cam running on the weber you have together with a mk3 2.0 bottom end hooked up to your auto box? It would be easy to find the head and bottom end in a couple of days and you have the rest already.
-
mk2 gti head blank of the injector hole or leave them in, throw my weber on top get it jetted to 1800cc and slam the 2.0 8v bottom end. will this bottom end bolt onto the 1600cc auto box?
will the 2.0 8v fit onto the original mounts etc. I am interested in doing this as i imagine i will be looking at over 100bhp right
waiting for the gang of professional gurus, lets see what they say, i think most of them are asleep now :drool:

From what i've read on here people just leave the injectors in rather than blocking them. A coolant channel has to be drilled into the head though but that is apparently quite easy.
I think i'm right in saying that the 1.6 and 1.8 have the same blocks and so the engine mounts will be in the same place as the mk3 2.0. As for the gearbox, i'm pretty certain it would go on if it was a manual box but not too sure if the fact it is an auto changes anything?
I think you're right though, wait for the professionals!
Just an after thought: you might want to improve the breaks if they are still standard!

1. 1.8 driver lump will drop straight in, the 1.6 & 1.8 lumps are physically identical, VW just dropped a different crank & pistons into a 1.8 lump reduce the CC.
2. Issues with GTI head are as above, injectors and coolant channels, as said leave the injectors in or remove the inserts and drop coins down the holes and thread em back in, I've heard 1ps fit, or was it 2ps?
3. Yep the 2.0 will bolt straight in, just swap the engine mount brackets to the 2.0 lump. Issues with this are the carb fuel pump, I don't think it will bolt to the 2.0 block, and the dizzy mounting hole is too small so you need an adaptor off TSR. You also need to swap the 2.0 dizzy gear onto your carby dizzy.
I'd also fit a 1.8 K-Jet GTI dizzy rather than the carb one, the advance curve will suit the GTI head/cam better.
4. Auto gearbox will bolt straight up, just buy the right clutch kit and bolt on your old flywheel. Just make sure you mark it with a 6degree BTDC mark, the carby 17degree mark will be too retarded to make the most of the GTI head/cam.
Haynes has the procedure, basically you measure a set distance from the TDC punch mark and put your BTDC mark on :)
-
Am I missing something here? how hard to put a K-Jet in ? Or is insurance a problem.
-
well that would involve fitting of GTI fuel lines, fuel pump, loom etc, where a carbed lump would be easier and be just as quick ;)
-
great info here,
so the shopping list so far consists of:
mk2 1.8 driver lump
TSR dizzy convertor
mk3 2.0 8v bottom end, with dizzy and manifold.
what shall i do for exhaust point of view? i dnt want to have to get a custom manifold!! The guy at TSR told me to keep the 1.8 driver block with the 32/34 and use the 2.0 bottom end as this would be quicker and less fiddly. Also he said that they did something similiar with a 8v gti cam in that and their version produced 110bhp.
-
well you don't need a 1.8 AND a 2.0 lump, just one or the other :grin:
You match the clutch kit to the gearbox, not the engine so either way you want a MK2 clutch kit, but get a 1.8 auto one as the clutch friction area will be bigger than a 1.6 one.
The GTI head is easy to convert, you just need to drill a hole in the back for the coolant channel, and block the injectors. Well worth it as you get bigger valves and a GTI cam included ;)
-
As for zaust, get a std complete 8v GTI system including manifold & downpipe at least, the 1.6 zaust is very restrictive. Obviously a stainless system would be a bonus, but it depends what you can pick up for cheap!
-
you just need to drill a hole in the back for the coolant channel
:undecided:
thats the bit scaring me from doing it this way because i go a bit mad with power tools! also i dnt want nothing leaking and breaking down, i want to be able to do it properly.
-
its not too bad, match the size/angle up to your old head, start with a small bit and work your way up. Drill till you feel it pop thru into the coolant channel. Make sure you flush any bits out thoroughly and bobs yr uncle, Haribo did this to his old 1.6 :)
If you still aint comfortable then go for a 1.6 or 1.8 carby head, they're identical.
