When i get this 1800Si transplant id like to beef it up to around 150Brake or more so i just wud like to hear some views on wot mods will get me there

Im thinkin
BMC Ram air carbon iduction kit
Decat exhuast and straight thru mid to a performance back box
Cams
FSE fuel pressure regulator
Chip
Lightened flywheel

Will this get what im after???

Ive read that mods like this will make the engine very rev happy and this is nice..but standard cranks and rods wont stand up to any more than 7800RPM so i may have to get steel H section rods and A steel balanced crank

This would make the engine lovely and strong but may cost a lot of wonga!

Low pressure turbo has been suggested but how much would it cost for one of these???


Ideas and comments welcome

NOS with a 50BHP shot

Those mods should give you around a realistic 35BHP. I'd get the chip so that it can be mapped to the cams but not the fuel pressure regulator otherwise it will cause massive overfuelling and may even lose power. It's usually one or the other....

I was looking a while ago at a light pressure turbo but can't remember who did them but the kit alone was £900 plus the fitting, but would give up to a 25BHP power increase just by itself.

I'll have a look around and see if I can find out the details for yer.

In all honesty i think you'll be lucky to get 35BHP. It'll be more resposive and there will be a gain but not much.

Cams add about 8BHP (Zetec figures)

Chip (unless its livemapped with give about 14bhp)

Lightend Flywheel (Wont give anything and seems a pointless mod for your car. With it being lighter it will spin up quicker giving you high revs with the sacrifice of a loss of torque. Then when you change gear the high revs will spindown quicker - For a roadcar it will be a pain in ass to drive around town)

Funnily enough I got chatting to a customer in work that had an Escort GTI tuned to 162BHP. To achieve he spend £1000 on a gasflowed/ported head with cams + doublevalve springs. Also had a piggyback chip and countless other mods.
He wants to stick throttlebodies on but I informed him that he'd need uprated management and the Galaxy 2.3 bottomend as the 1.8 crank wont take the stress

All in all the guy had spend about £3-4k on engine work for 160BHP

Fit an ERST motor - gonna be much cheaper to get more bhp from it, and the initial conversion cost probably wont be any more expensive than the RS1800

Dont forget to also uprate your suspension, and especially brakes though

dammit!!
The thing is i have a donor car with the !.8 in it and its basically cost me sod all for the engine. The swap is also very very easy to do.35BHP on top of 115 makes 150! so if i get those mods(except maybe the FSE and the flywheel) then ill be happy with RS2000 power.All i need is some poke,not lotsa poke but anythin above 130 at the fly and im happy

Cheers guys

zetec turbo = expensive and un-realistic unless your willing to pay through the nose and replace near enough everything

I know the fezzie rs1800 runs 130bhp as standard. So 150bhp from a 1.8 sounds realistic to me.

i cud easily get 190bhp from the engine but it wud cost thousands, anything is possible, i cud see the far side of 140BHP from the 1.4 but it wud involve a rebore,blueprinted engine running hi lift cams,chip,low pressure turbo, low comp pistons,need i go on!i could blow the 1.4 engine to pieces with just a few mods its that weak,im thinkin of gettin a honda as they are hard as nails

The lightened and balanced flywheel will just help the engine rev up better (You'll also lose torque) and wont increase engine power matey.

Apparently, to go from 115 bhp to 130bhp on the 1.8's, its a throttle body and cam change

it is mate cos thats the xr3 power output and all it has is a better set of cams,body and maybe a slightly different program on the ECU.
What would happen if i put the 1.8 ecu in on my 1.4????

Just curious, would it give me a 1.8 fuel/air mix and thus up my power/compression and blow my engine up possibly???

Would the power gain be worth all the trouble.

If you going to spend loads on getting more power, may aswell take it up to 200+ BHP

realisticly, zetec engine or zetec turbo'd engine into your car isn't worth the time/effort/expense.

you'd be better off going for a CVH engine which is older technology so easier to put into your car, turbo option is more realisticly achiveable as well, performance parts for them are cheaper too

ADAM= i have a 1.8 in my possesion remember,wheres the CVH??
My car is exactly the same as the 1.8 same loom and all,prolly the same radiator but i want the new one as mine is full of radweld.
Cost of engine fitting into my car=250 quid max
increase in power when conversion completed=45bhp
top speed of new engine=at least 130,instead of 115 down big hills lol.
If i do the conversion myself with a few mates itll cost about 100 notes and a few cr8s of beer.

IT IS gonna happen me thinks,also it will increase the re-sale value of the car!

i think im definately goin to a subtle euro look on the outside now as the bodykit does my head in

ahhhh didnt know u already had the engine!! doh! haha

you sure its the same ecu? you might wanna check the codes etc, is it the 115 or the 130 engine?

Ggrrr!
The 1.8 is either 105BHP or 115BHP. If you fit 2.0 TB, GTI ECU, GTI MAF, 130spec cams that SHOULD take it to roughly 130spec depending.

Seems strange u didnt jump on my bandwagon and get the 2.0

the ecu is different but i have it, the loom is the same tho,its exactly the same system.
Engine is 115BHP, ill go one better than gettin the Gti ECU, ill chip the Si one to give even more power and so on.ill deffo be gettin large throttle bodies asa well, i may get the biggest possible, ie/ foci st170 TB, see if it fits, ill have to do my research on that tho.

Dazza,ur bandwagon costs too much, my bandwagon makes money

the focus st170 manifold has an ecu i dont know if you would need that aswell but it should fit

To use the ST170 manifold you need to cut the fan cowling and tilt the radiator braket to give the manifold the clearence needed.

Ment to be a good mod but only if you have the power behind it - U dont want to loose backpressure!

If u take this route, floor the engine and if the revs take awhile to drop you've lost backpressue :S

maybe i should have put inlet manifold (oops)

Didnt think you could do that? Doesnt it mess up the Throttle position, Idle and the air/fuel ratio?

Not heard of that one done before

Sounds like a lot of hassle to me matey

Not convinced about the looms being the same though Your 1.4 has a carb on single point injection, so the injector rail is prolly going to be different and does your car have a MAF sensor

Bolting the 1.8 ECU to yours as it is will be no good - it wount be able to control the air / fuel mix as its a carb, and wont have the sensors needed.

My guess is you need a 1.8 loom, all conectors, and ECU and drop everything in at the same time, and as Ive found out from past experiences, its a good idea to get the motor in, and running as std before playing with it. Messing with them before you drop them in just increases the chance of problems, and they are harder to find

Dude my 1.4 is MPi fuel injection. As if i would ever own a carbed engine! When i wasw 17 the one thing i had to have was a fuel injected car so i cud have my 57i lol. how petty am i. Im pretty sure the looms are the same but i will lokk through my haynes manual to check. I dont want the 1.8 loom as that will try to route signals from systems i dont even have(ABS etc)Both the ECUs i have use the same connection to hook up to the loom, same plug same cables in the same slots

i dont know where about exactly, but some feller on a site my mate is on is developing a supercharger for zetec engines!

Aparantly its about £6-750, i'll see if i can find the link!

at least 130 is optimistic out of a kitted 1.8 mate. my mate has got an Si that he has made more lightweight and had fe wittle engine mods, and he is lucky to hit 130!

Why not simply throw a bottle of Nitrous at it ???

This can give you variable power gains up to approx 75 bhp.

nitrous seems expensive and dangerous.

600 notes for the kit and then 50 pound per top up. I want the power there 24/7

Surely 600 pound can be better spent?

BMC ram air, full performance exhaust, Cams. Thats 20BHP ish right there

Not when Zetec cams are £550!

oh crap lol, thats a rip off, why cant they be cheap. cams are cams IMO. Some can be bought for 170 notes, why cant mine

iv had 120 ish mph in forth gear in my escort
tho it didnt go eny faster in fith

Now ive got my Si the big power is major on the cards now

Cud i just whack the 1.8 block over to the 1.6. Would this be easier than pulling both engines?

I can get the 1600 up to 130+ real easy. the car my new throttle body and AFM came from had this power on his 1600 Si. The mods he has on a 1.8 would be even better. Yum yum

Why didnt you just buy a 1800cc car ??

In essence you will be nearly replacing every bit of the motor, so is it worth it? You can get a 150bhp engine for a fraction of the money you will spend getting less out of your current one.

sell the car buy a more powerfull 1. if people didnt sell cars id b out of a job.

if that fails. zetec cams sound gud. maybee chip n remap or simular 2 help her wid zorst n filter.

Already got an 1800 Si,its a write off but im using its engine, insurance on a 1.8si is a bit steep right now, And what sounds better, A 1.6Si with enough mods on to make it 115PS or a standard 1.8 lump??? Its all about modding, if i wanted a fast escort id get the RS2000,but the huge insurance costs makes it a bit unnaccesable. Just work the 1.6/1.8 as and when i can afford it to get it soundin and runnin just as i like it.

I could say that to any one of you lot. For instance why does scooby like overboosting imprezas when a lotus esprit has that sorta power as standard? Personal preference
