Right folks, whats the lowdown on these engines. I pick up the Si on Saturday and I've decided to do no mods untill I save up enough for a conversion, rather than p!ss it away on pointless mods that will get me nowhere.

Whats the BHP on both of these engines, and positives and negatives about each. Also, if ye've got any info on cost etc - this would be appreciated.

I know this is probly a common question, but I just want to get some fresh views, and the definitive stats to compare for myself. Obviously the cost will have some bearing on my choice of engine too.

So lets have your opinions!

[Mav Singh]

as far as i know the 2 engines are almost the same power wise, well 128bhp for the 1.8 and 135~ for the 2ltr. I would go for the 2 ltr because it will be running a lower compression to the 1.8 because the power per ltr is lower on the 2ltr. also the 2ltr will provide more torque throughout the lower end of the rev range so i assume it would be a better drive at around 2k rpms. a larger block will probably be more reliable since the 2ltr would be less stressed???? to produce the rated power then the 1.8 would.
thats just my opinion, oh and it would look awsome on the log book stating 1997cc or summink

RS1800 Tech Spec...

http://www.rs1800.com/tech_spec.htm

I'd say 1796 has a better ring to it!

[ChunkyMunky]

cheers buddy

Those are pretty mcuh the figure I expected to hear, but was just wondering about the power output being so similar It will be interesting to hear the views of all the peeps on here, as I dont want to be wasting me money. I've also heard that the RS engine is super easy to fit, which is a bonus.

I patiently await more opinions! (and engine prices(ish))

[ChunkyMunky]

cheers to you too chumkila. I think the RS spec is pretty impressive... still blind as to how much a peachy one of these would set me back. I'm not dreaming either, as I have at least a few hundred quid to spend once I have the car Want to sort out performance before looks

[AdrianFRST]

Just to be pedantic, the RS1800 is 130ps which is actually 128bhp

The 1800 is easier to fit yes, same mounts, inlet etc. The 2L is more readily available and cheaper.

[ChunkyMunky]

Please excuse my 'thick as pig sh!tted ness' Adrian, but what does 'ps' mean, I'm so used to talking in horses, and I see this on the site quite often, frustrating as I dont have a scooby doo what it means

2l easier to get my mits on, whats the price diff (roughly,... obviously).

cheers

[Mav Singh]

ps is the jap rating i think, 1ps = to somewhere in the region of 0.95bhp but im not sure on that.

[chumkila]

Adrian stop confusing the poor chaps!!

[paulbaker]

2L anyday i pent ages looking for a RS engine and all the ones I found were dubious in quality when I was looking. Also remember Henry Ford made a limited no of RS Zetecs anyway. There are oodles of 2L Zetecs around, the conversion is a bit more complex (but not much) and if you are going from Si 1.6 Zetec it's even easier. The added torque from the 2L make it no contest and you have a better base for more power ie TBs or Turbo in the future.
When I did my conversion I talked to loads of people and the answer was always the same--2L mate

[ChunkyMunky]

Thanks for that buddy that could indeed save me loads of wasted time and effort by the sound of it. So, 2L, just take out the old 1.6 si lump, fire in the 2L - ECU & change over the sumps... is this ALL that is required?

This is looking good guys, as I know a chappie breaking a mondeo with a 2L Zetec - good nick too.

[paulbaker]

Rip out 1.6 lump-bolt on 1.6 bits to 2.0--- sump, inlet manifold, exhaust manifold, dipstick tube, water pump and PAS pump if you have + drive belt, oil pump (or alternatively use Mondy oil pump with CVH filter)

Use Mondy ECU (plugs straight in) and Mondy injectors, MAF unit and Throttle body.

Took me about 3 days all told--with help reckno you can do in a week end. Remember not to skimp though and replace things like cam belt, gaskets and also a good idea to replace the front and rear oil seals whilst the lump's out. 10 minutes with lump out bloody hours if the fail when lumps in!!!!!

[ChunkyMunky]

Many thanks yet again. So is this everything that needs to be changed over? If so majik - and cheers! Looks like this could be a mod happening in the very near future One thing though, the engine is in an auto just now, which means (i think) i'll need to get a different ecu, dunno how much this will cost nevermind, long as the engine is sound

Yes, you need a manual ECU--auto is COMPLETELY DIFFERENT you need a Mondeo 2.0 ECU designated as (DEEP, DEWY or DESK) these are the 4 letter designators which are on the label on the ECU. I also started with an auto Mondeo so had to find an ECU (I paid £25 for mine from loot which was lucky a scrappy will charge anything up to £75.

ALSO VERY IMPORTANT IF USING AN AUTO ENGINE---YOU NEED TO ALSO CHANGE THE ALLOY CASTING THAT RETAINS THE CRANK SPEED SENSOR. THE ONE ON THE MONDEO AUTO BLOCK POSITIONS THE SENSOR IN COMPLETELY THE WRONG PLACE WRT THE Si FLYWHEEL. I MISSED THIS AND AS A RESULT HAD TO DROP THE BOX OUT AGAIN TO CHANGE IT. WITHOUT THIS IT WILL NEVER START AS THERE IS NO SIGNAL FROM THE CRANK SENSOR. THIS IS NOT MENTIONED ON ANY OF THE OTHER SITES THAT I KNOW OF.

If you let me have an e-mail addressi can send you a copy of the article I wrote re the conversion if you want

Matey--a truer word was never spoken

[fiesta_fras]

been told by quite a few ppl in the know that the 2L is an overbored 1.8 effectively

might be crap, might be some truth in it, the walls gotta be thinner thou surely

[Phil Si]

i dunno i think this might be the case...

but if people have had turbocharged 2.0's like paul R... and sunny .. surely its safe? specially NA?

[Project]

It is safe, but the fact remains the 2.0L Series one and two engines seem, to all intents and purposes, to be an overbored 1800 as the distance between each cylinder is less, and I have heard a rumour of the 2.0L using siamesed bores - no water jacket between bores 1 & 2, 3 & 4. A reputable engine tuner may well be able to tell you more.

Fact remains the Zetec block is unlikely to suffer from any problems due to it's design

[Ian C70T5]

I dont thnk it is an overbored 1800, cause if you have a 1800 block you can only bore to 1900 and that is not very safe, yet with the 2000 block people are going to 2048/55 and are fine, if it was a matter of just boring the 1800 would be used as its got loads of correct parts (if you see what i mean)

[chumkila]

They only go to the larger capacity because of the pistons used however its an intriguing thought and discussion.

[Ian C70T5]

Cant be cause of the pistons used mate, cause everyone would buy an 1800 and just bore that to 2.1 and put the same pistons in as i am for my 2litre to 2.1 conversion..

[lee 1.6 si]

How much would you pay for a 2 zetec with about 30,000 on the clock? Would you have to get the engine delivered to the garage and then get them to fit it or would they do it at a scrappy? What the ps of a 2.0 anyway.

[chumkila]

naah Ian i meant the 2.1 capacity comes as a result of using certain sized pistons in the 2.0 engine obviously not in the 1.8. that'd be fantastic tho!

anything between £250-500.

the delivery to the garage/engineer is down to urself. transport it by car-boot or van.

ps of 2.0, god knows.

[Project]

Ian,

The casting is different - I specifically worded what I was saying because I know that it's not just a matter of overboring the 1800, but that in designing the 2.0L it looks like the design team effectively did just that - removed a couple of waterways, shuffled some stuff around, and overbored it.

Ideas?

Al

[ChunkyMunky]

I know nothing of this 'boring/overboring' malarkie, I'm too thick for that, and wont even pretend to know what I'm talking about

It looks like I'll be doing the 2L thing (thanks to detailed insight courtesy of Paul Baker) in the near future. Anybody got any views on using standard Si gearbox, as opposed to fitting the 2L one? It's just my engine will be coming from an Auto, which means I'll have to source a box from somewhere else.... Gear ratios in Si box, they up to it? (bearing in mind acceleration is what I'm after)

..... just seen a Golf R32, thou hast cometh in thine pants.

[Nick 2i]

chunkymunky- your si gearbox would cope with it you would get good acceleration but lose a bit of top end.

thou hast cometh in thine pants.

you should go the doctors bout that mate

[Project]

Don't use the Si gearbox - you'll be revving the knackers off it at 70 when you really don't need to.

Al

[ChunkyMunky]

hmmmmmm sounds like conflicting opinions.......

Anyone had both, and can offer comparison?? as many opinions as poss chaps and chapettes.

oh, and nick, my doctor's quite nice - so it just happens every time I go there to, not much of a cure

[Phil Si]

i got a 2.0 on a 1.6si cogbox... it is rapid as fook, but as said u do loose top end.. u get about 120ish lol

but 0-60

[ChunkyMunky]

So, Phil, with your egg timer on the dashboard ( ) roughly whats your 0-60 then. (dont want to start the 'how can you accurately measure your 0-60' argument )

[Phil Si]

no idea dude, feels very fast but is probably 7ish lol... will have to get a mate to accuratly time it lol

[ChunkyMunky]

Aye mate use the sun to time it, just check the position of the sun in the sky at 0, then check it again when you reach 60, that will be well accurate, thats how they time F1 (honest)
