Turbo Zetec

iTrader: (1)

right, all this talk of not being a real RS has got me thinking... most people see RS's as tune-able for not alot of outlay. why can't this engine be made into a cheap 300+bhp turbo motor? it has alot going for it really, the head design is good, the valves are a good size, the bore is a very handy size for bunging a cheap set of mahle XE pistons in

i know people will probably disagree and say X engine is easier or Y engine is cheaper, but think about it... a set of XE pistons scrubs 1.8mm off the compression height and has a 0.8mm bowl... add some valve springs and the manifold off an SR20 (which apparently lines up perfectly) and you have a cheap base engine to make power with.

with a cheap zetec, you have to bore it to take the pistons, make the rods take the pistons too, still sort the springs, etc etc.

can anyone actually see a disadvantage of this, aside from the weight difference?

had to get an opinion or two, as this has been running through my head all day

yes but its alot easyer bolting a zetec into a cvh bay then it is an rs2000 engine also the zetec engine come in alot more of the ford range so will be more common so if its more common there will be more of a demand for tuning parts for it. hence the rs2000 engine never caught on that mach

i'm not talking about bolting it in to any other bay, although it might make an awesome way to have a sierra with cheap cossie power if you take the unit from a scorpio and do this

another note, i may have found an easy set of pistons to sling into the 2.3 to give it low comp (don't worry, they're strong), but i'll measure these properly tomorrow.

If you take a DOHC 8v Sierra engine and stick a 16v Scorpio head on it then you have an RS2000 twincam motor but in RWD format, if you use the full Scorpio engine it's shite as it has the balancing shafts in the sump.

I bought a ready built one off a geezer last year, just aint got round to fitting it yet.

There was a bloke in Classic ford with one in a cortina that he had slapped a turbo on.

balance shafts are easily removed though

But you still need a sierra sump to clear the crossmember (if you are putting it in a Sierra), and then you would need to make up some fillet to block a hole left by the balancing shafts.

I am only going on what I have read - I have not done this myself, but did look into it heavily a while back.

A lot of folk do the 2.3 block.

When I looked into the 2.3 it was hard to find a set of pistons from another engine with a low enough crown height...

YB pistons are a bit bigger on diameter but the crown height is too tall, you may be able to get round it by using the shorte stroke 2 litre crank but the little ends are still different IIRC

Look on the rs2000-16v.com forum for help, head honcho Fr3nzy has an RS2300T, search "vortex" on there for ideas

bbr did a turbo conversion for these in 1992
hardly any fooker bought one

Thats because they were all at Turbosystems having there YB's tuned to the max

Tis what I have. I run the VIS from the Scorpio also. Lets it bimble along on tick over quite nicely, open the throttle over 3K and it comes alive. The twin air intakes are larger overall than the Sierra 8V. I also heard the Scorpio head flows better than the RS2K one. The 8v bottom end will survive a nuclear strike. I always wondered why no one developed this engine, after all, how did the YB come about? I got a few spare blocks and heads so am looking to experiment with a turbo set up next year. 2 litre, 16 valves, can't see why this engine would be harder than a cossy, I think it's just because no one can be arsed.

I know what you have, your Saff was sat next to mine at last years Ford Fair

You dont recognise my user name on a different site?

Anyway, I am going for that engine swap real soon (honest) and of course a turbo would be great.

Why would people bother spending all that ŁŁŁ on a FWD Escort not quite Cosworth?

Loved my 2k, but tuning one with any real power gains sticks your budget straight into saff 4x4 or Escort Cos money.

Cossie Sean

its a heavy motor,

MASSIVLEY underrated turbo potential wise and the malteese and greek run these at 600+ FWD!!!

i much prefer n/a for the noise

but tall, putting them in mk3/4 escorts create height issues

bulletproof the ones ive had and they got abuse constantly, pair of cams, bit of head work chipped/mapped and ARP rod bolts, my blue 2wd one was a stormer and regular beat XE corsa/nova boys at york dragway

and sounded the absolute bollocks with a full stainless, not noisy but high pitched revs (7800 i think)

love another one actually but im a RWD man and after looking for a RS2000 after seeing the "other" post i was on ebay looking for a cheap one, ended up bidding on cheap BMW e34 535i`s and A8`s.............

still i will have another pacifica one soon i hope

Just my 2p worth
