1.6 cl engine to 1.8 'cd' engine from a GL...differences?

[doninphi]

Right, 1981 cl 1.6 b2 80, and am aquiring a 1.8 gl 'DS' engine for a decent price, not a massive gain but enough to give it a bit more poke, and my 1.6 has a few issues at present.

Dan says the engine may NOT have a carb, and if it does he says he thinks it might be tired. I dont think it has an exhaust either.

So my question is, from my complete 1.6 unit, what can I keep onto the 1.8, and what will I need new?

e.g. my 1.6 has a recon altenator, nice rocker and air box, water pump is spot on etc...

Ideas?

Thanks
Phil.

Only differences between 1.6 and 1.8 carb engines except for stroke [so different crankshaft and maybe rods/pistons] will be carb. U can keep your alternator, water pump, exhaust etc.

Now that is the answer I wanted!

Now for another question then, is there any simple modifications I can make while the engine is out to improve it?

I guess I could match the port sizes etc... Are there any better cams that are a swap from another engine or anything? (like the kr cams on the 6a for instance)

Thanks so much, now I know all I need is a carb if it hasn't got one, might try and find an upgrade there too.

i know on the 1.6 and 1.8 carb golf engines you could fit a gti camshaft,if your fitting an 1,8 engine you may be able to use 1.8i exhaust manifold and fit a bigger bore down pipe and exhaust,webber carb with a sports air filter the panel type that fits in the original air box

So basically all the bits of a 1.8 carb Gti engine then? Sounds good, werent they good for 112bhp?

I'm not keen on the exhaust, but the rest might be a goer for now... When you say a webber carb is that stock on the 1.8Gti carb or do you mean an aftermarket twin choke jobby?

aftermarket carb,yea the 1.8i was good for 112bhp as for the exhaust you can have a standard 80 sport one if the manifold fits the head ok as all the exhausts are the same pattern just bigger bores

i will be trying a few things on my 4000 when i get to doing the engine which is a 1.7

GTI 8v engine [basically the same DZ from B2 A80 GTE] has 112 bhp because of fuel injection not manifolds
P.S. Dunno about golfs and B2, all B3 8v engines have the same exhaust, including manifold.

i didn't say the manifold make all the difference but the injection down pipe has a better flow and the exhaust bore is bigger which helps the engine breath better if using a bigger carb and sports airfilter

It made 112bhp in the injection 'digifant' gti as I had one, however the k-jet model in the earlier cars was the same bhp and ran carbs!

Edit: woops no! K-jet was a form of injection, my bad!!

Oops! This is a DS engine, tho I'm sure all of the above still applies yes?

Thanks
