205 engine

Well my GTI engine is getting is running fine i`m just finding its lacking a
little power.... It`s only a 1.6i and have heard that i can put a 1.9 block
on it....?
Is it true ?
Also if that`s the case can i have it over board to a 2.2...?

Who still does that now ?

Thanks

 

Just go buy a complete 1.9 engine. You can get a decent one for £100. But
keep the 1.6 gearbox. The 1.9 gearbox is quite long, but the 1.6 box will
make it a bit more lively.

And no, you cannot bore the engine out because it is a wet-liner design,
meaning there is no where to bore too. If the 1.9 8v isnt spritely enough,
go for the 1.9 16v conversion. Or even the 2.0 8v Turbo conversion.

 

If you really want that sort of power in a death-trap little box ! Glad to
be rid of my 205 - after driving larger cars it just feels scarily small!

I personally would avoid the 2.0 litre blocks due to being made out of cast
iron and therefore being heavier. In such a small, lightweight car, I'd
expect it to kinda muck up the handling somewhat, shoving a turbo or even
the newer 1998cc 16v engine in the front.
However, a 1905cc 16v engine is alloy and will consequently weigh less and
in my opinion is a better option, but will still weigh more than the 1580cc
block. You also have issues of reshaping the bulkhead to fit the 16v's
exhaust manifold/downpipe into the 205's engine bay.

In terms of straight-swap potential, the 1.9 8v engine is a good way to go.
If you get a running engine, you can simply pull the old one out and plonk
the new one in. Alright, it's not quite *that* straightforward, but it's
easier than trying to cram a 16v engine in there. If you're up for the
challenge though, I'd go for the 16v (although you do loose a bit of
low-down grunt in the process).

Hi,

If talking about XU10 series, I'm affraid they're made of steel, not cast
iron. Diesels are made of cast iron (this supposition is made in case I'm
wrong with terms).
Anyway, true it's heavier, but XU10s are dry-liners, so they could be bored
out... Bit of a dilemma, here

A good choice could be to fit a 1.6 head over a XU9J2 (SRi) engine. A friend
of mine had done it, it rocks ! Not sure about reliability, though.

 

Really? I always thought they were all cast iron. Must've got confused

That's true. I've no idea how much heavier the XU10 block is - if it's not
*too* heavy, then I guess it could be a viable alternative - but I do think
it could be quite detrimental to have the heavier lump up the front of the
car.

What sort of power does that output? Might consider it for my 305...

Chris.

 

Hello,

Not that a problem, perhaps later XU10 were made of cast iron.

TBH I don't think it's a viable alternative, as the power/weight ratio is
rather favorable to XU9s, as, for example the XU9J2 (SRi) gives 125HP (DIN)
where its successor (XU10J2, steel block, cat'd) was given for 123HP (90kW)
DIN, but IIRC the XU10 has a better torque. A dilemma I said

Dunno, as he didn't bench it - it was a kind of "garage" project, and power
benchs are not that common. Fit with 1.9 (15") alloys, skids up to 3rd gear
(he kept the 1.6 gearbox).
The reduced chamber volume is a part of this extra power (I explained it in
an earlier post), but *may* bring extra stress on head gasket, and that's
what I implicitely expressed by mentionning the possible reliability
problems.

 

I dont think you have to 'adjust' the bulkhead. Its been done so many times
now i think you can actually get kits (possibly with a smaller exhuast
manifold?) so it all fits straight in.

 

Sorry yeah you're probably right now I think about it. I just remember that
the original Mi16 manifold/downpipe setup fouls the bulkhead, so you either
need to beat the bulkhead with a hammer, tilt the engine (which can cause
oil starvation problems but would be what a cowboy mechanic might do) or of
course, as you pointed out, get some sort of aftermarket system. You'd
probably be able to get something custom-built to fit, but I'd imagine it
wouldn't be cheap.

One of the things i fear was weight !!... so how would i go about a turbo
converstion myself.. what parts would i need to source ?

 

Well, an engine
If you get all the ancillaries with it (basically you want the turbo,
exhaust & intake manifolds, AFM and all ECU's), then you'll pretty much have
everything.
I think they're most commonly in Citroen XM's if I remember correctly. There
was one on eBay recently so I'd keep an eye on there for an engine. I seem
to recall it went very cheaply (was thinking of buying it for my 305 but
gone off the idea).
I have to say, the turbo conversion would certainly make an interesting
change from the standard 16v conversion, but I think it would be somewhat
harder. First off, you have all the extra parts and stuff to fit in the
engine bay. You might consider custom-building the pipes from the turbo to
the air intake, with an intercooler over the top so you've got a reason to
stick an air scoop on the bonnet, if you like that kind of thing
You'll really need to look at an engine and figure out how it'll all fit.
You have a bit more to worry about on the exhaust manifold than just where
the downpipe pipe goes.

But Ecosse do a 200+ bhp upgrade kit for the 2.0 8v T
