hope this is the rite section

just wondering how easy...and for what price i can tune an rs2000 engine (escort) to get a bit more out of one. iv heard powerchips are worthwhile? but other than that i havnt a clue what i can do to a budget.

i have a set of dellorto twin 40's lying about, would they make any difference? its only going to be a weekend/track car so fuel consumption doesnt bother me but i dont want to be loosing out (wouldnt mind the sound tho!) only two things done so far, the egr (think thats rite, on the manifold?) has/is being removed and a full stainless system with a decat

any help appreciated!

The budget is the problem bit, if you put carbs on then you need something along the lines of ignition management to get any worthwhile gains.
Maybe msd etc have some chips to suit wilder cams for these ?

how do you mean with regards to ignition management? can i not use the existing spark from the ecu coupled with the carbs that are manually tuned?

what sort of budget would i be looking at to get betweensay 160-170ish bhp from the standard 150ish?

im wondering if there is anything i can do with the money i have to make a start or if its better to save a lump some and do it all at once.

i apreciate with the mods done and a chip i will be looking at little more than standard power.

does removing the egr off of the manifold make much difference? as i hear they choke up/stranggle the engine a wee bit.

thanks for the reply

you should be able to do away with the ecu, IIRC they use an edis/esc system which can run standalone, although not as good as a fully mappable setup.
twin 45's will really be needed, 40's just won't cut it up at that power.
as for egr, it shouldn't strangle performance is it closes the valve when giving it some and only come on at cruise to maintain economy and reduce emissions.
you can just blank it off though, or make sure the valve is just closed.

also to get the power up 10-20bhp over standard shouldn't cost much at all, upto 170bhp should be pretty straight forward, nice exhaust filter and a good setup should get you to that.
cams to pull you upwards, but then you'd need to start looking at higher comrpession etc.
probably cheaper to fit a zetec engine, where parts are going to be cheaper to find.

kniterider

i believe twin 40's are good to about 165bhp? they were gonna be used on a different engine so il either use them or sell them.

as to a zetec, the reason i didnt put one in is they are expensive to tune and the out the box power is poor. a 2.0 mondy is only 135bhp even if its a tadge lighter.

from dyno runs iv seen 156 was the highest credible reading from exhaust/filter/chip combos and i believe cams (still learning about these) only help you decide where you want the peak power not give you more?

upping compression could be an option as could home made throttle bodies. has anyone/or does anyone know someone whos running one of these on carbs?

I read on escort evolution that you can use a 2.3L bottom end out of a galaxy its not a straight forward conversion but it might curb your hunger for more power.

mark.

I don't know about getting rid of ecu altogether an going edis, as it needs something to advance retard the timing, and I was under the impression edis was merely the amp combo, needing still advance retard to be calculated and signalled.
40's power would depend on what size chokes they have, as these are changeable, but usually around 80% of the carb size so 90% of 40 would be 32 in each side(throat) of the carbs, but can go bigger.
Cams can/will give more power with the right fuelling, but do as you say alter the point at which the power is produced.
A car I was watching yesterday on the rollers, a nice mk2 cortina running a V6 cossie lump, whose engine was made/put together by a "pro engine builder"(not owner) had 4 cams all timed up wrong, lift on overlap was 10 50 5 210+, amazingly it still did 176.6, but no more with the way the cams were, the owners going to have a "chat" with the engine builder!!
As said the EGR should not affect power, it is used to reduce the combustion chamber temperature, nothing at all to do with economy, it is used to stop the NoX emmissions as these occur when chamber temps get high enough and are particularly nasty, recycling gas actually helps cool the chamber down.
If you do blank off/remove the EGR, just don't throw the exhaust gas pressure differential sensor, as on some ecu's this puts it into LOS mode, it still needs to be plugged in, even though not doing anything.

understood everything there EXCEPT the bit on carbs lol
didnt realise they had chokes?

anyyyyway. so basically would i see an increase in performance from twin 40's or is it a waste of time? how about twin 45's?

if not il sell the carbs filters and tank iv got and make some money back from the conversion

tabetha

I'd go for 45's, the "choke" is the size of the centre part, which fits in the mouth of the carb, you can get all manner of sizes, 45's usually ran 36mm's, but I ran 38 and 40 on mine, the loss of bottom end over FI is untrue though.

doing a 2.3 conversion is the only way forward for these engines buddy unless you want to start chucking endless amounts of money at it!pretty straight forward conversion and will get the gains your looking for! very torquey motor at the end of it aswell!

Hi, In my old rs2k I had
Superchip - Ł100
Fast road cams - Ł150
Blanked off egr manifold and heat wrapped.
Remove the exhaust manifold and remove inner welds then weld outer welds on it.
De cat, I had a J reg so it was legal.
Janspeed exhaust.
You can go down the turbo route but you will need a mega squirt ecu, cosworth fuel pump, calibra turbo pistons, s14 injectors, s14 exhaust manifold and turbo.
You can get away with standard rods as long as you don't go mad with loads of power and high revs.
If you get rods then I have seen an rs2k turbo with 300bhp. The rods are not cheap!
If you go down he 45 route with megasquirt I've seen 240bhp
Join rs2000-16v.co.uk they have a 2.3 guide. More torque and around 170/180bhp
I wanted to go down the turbo route but ended up breaking the car up due to rot.

kniterider

Rsailor, what increase did that give you mate?
il enquire about the 2.3 swap, been told its expensive to do tho and requires a fair bit of fabrication?
id like to keep it N/A for now tho, 20 with no no-claims is expensive enough! lol
tried to open the link on the rs2000 website but in the tuning bit about the bottom end it keeps opening the page as an error

kniterider

just found the guide you spoke of...looks to easy tho lol not that im moaning...obviously iv got the rs2000 engine so can use the parts off that, so other than getting a few bits blocked and machining a bit of metal to fill a gap i can pretty much up and running (assume need new management) as long as i use fuel over 97 RON?

Rsailor

From memory, I think you retain the rs ecu.
I didn't have the car dyno'd but I'm sure it was well over 170-180.
I very light port with mirror finish polish, It took months of evenings to do it!
Combined with removing as much as I could, dynomat, trimming all metal and sound proofing.
It was very quick!
I'm looking into getting another rs but I plan on doing the turbo conversion.
I need the money first though! I am going to buy the parts first, then the engine and then the car. I plan on getting a Mk5 J reg due to emissions and not having a cat.
I am still looking into the ecu, might see if the L8 from the cosworth could be used then re mapped.
Pie in the sky at the moment as No budget.
Good luck with your rs mate.
I love my rs's and was gutted when I had to sell mine.

Bike bodies and run them off a unichip. You retain your oe ecu and can all be removed and returned back to standard. Highly reccomend unichip if going down the 2.3 route if using the rs head due to cr and not wanting to spend out for aftermarket management.wouldn't bother with the carbs personally

tabetha

I've seen duratecs put out well over 300bhp n/a, with nearly the same torque, at nearly 10,000rpm though!!
YB it!!

im doing this conversion into a MK3 fiesta it was originally an XR2I but had problems with the bores and pistons so was told it would be cheap to get ready made power from an RS2K engine im thinking of going 2.3 also just been offered a galaxy engine for Ł100 what would i need to make it run im planning on cams cossie throttle body ecu live map filter and exhaust how much realiable power can i get out of this lot ? sorry for the thread hijack just need help asap cheers

hi mate i have bike bodies ,megasquirt,pipercross filter,custom made manifold for the bodies the lot needed for this conversion megasquirt has been mapped for this too drop me a pm if intrested
