wats needed for for a zetec turbo conversion for a s2 escort rs turbo

 

Everything.

 

zetec bottom end, cvh head with all turbo bits, manifold, inlet etc etc.

You need to do a few things to the zetec block to make it worthy, nothing major if you are on a budget but a lot of people on here will recommend forged pistons and rods but they arent really needed unless you want to run any more than 280 hp.

google zvh turbo and have a look at the quantum kit car page... it has everything you need mate. Any questions ask as im just starting a build myself

 

not a zvh just a zetec engine outta a focus or something

 

mechanically you need to do the following at least:

Skim pistons 40 thou or fit a decompression plate
Blank pref weld 4 oil galleys on block
blank oil return on zetec block as it gets in the way of manifold and turbo
tap in a return for the turbo oil pipe

thats about it really, you also have to fit a cvh water pump, drill the flywheel 11mm to open up the holes, run a spacer shim to fit the gearbox, use the cvh bottom pulley, put a washer behind the cam gear or bottom pulley (cant remember) to space it out so the belt lines up.

Think thats about it... i prob have forgotten a bit but the majority is there mate.

 

oh sorry mate got my wires crossed.

then you need to put an rs1800 head on it and convert to efi... you also have to modify one of the mounts

 

sorry mate a zetec turbo, ha ha right then... you need to tap the block to accept the cvh manifold and then lower compression... you will need to do something about engine management also

 

why would he want to skim the pistons or run a a decomp plate ? and its full zetec he wants

 

This might help http://www.fiestaturbo.com/articles/zetecturbo/

 

cos he wants a zetec turbo

 

what! so you cant just leave it @ 10-1 then

 

no mate its too high! need it down to 8 to 1 or lower!

 

ok mate but im running 350+ and my comp is miles higher than 8-1.

 

Peak power has little to do with static compression ratio though...

 

Engine
Manifolds
Turbo
Exhaust
Management and loom
Water Cooling
InterCooling
Mounts
Fuel pump to suit fuelling demands
Injectors ""
G'box to handle the power
Better Brakes + Suspension to make use of the power
etc etc

 

zvh is not the way to go IMO, more work to put an antique in there when you get a free better one with the bottom end.

 

zvh is only good for one thing, being able to skimp on management and run mfi, which i dont know why anyone would want to keep it lol

 

will people stop talking about ZVH the poor bloke wants a zetec turbo- read the fecking start topic
You'll need- easiest path for a relatively easy 250bhp

silver top 2litre from a mondeo
efi management of sorts(ofab/cossie/gotech etc)
all the sensors for the management you've chosen
aftermarket oil cooler
A decent breather
uprated intercooler
decomp plate to bring compression down to around 9:1
frst inlet or modified mfi inlet.
stage 2/3 t3 turbo with -31 actuator

thats just the basics off the top of me head plenty more i'm sure.

 

You don't need an oil cooler or aftermarket breather kit (well not unless the engine is shagged )..

9:1 is too high on the standard cam package at that power level, you'll run into det.



rudkinrst- to answer your question, what's needed? probably a phone call to Area Six

look at my thred it mite help

 

i didn't realise that, care to reccommend a compression ratio and cam package then seeing as you so quick to correct?
and your going from n/a to turbo so i'd always say a decent breather and oil cooler is needed.

 

Of course! I have no issues offering useful, factual information. On the standard cams, 98RON fuel and say 1.2-1.4 bar on a T3 (to get your 250bhp), you'll want a CR below 8:1. I have personally had issues with det @ 8.5:1 above 200bhp. For over 300bhp i'd go even lower.

With regards to oil coolers, I think sometimes people actually forget what they are. The hint is in the name. They cool oil. You only want to cool oil if it's too hot. If you don't know if it's too hot or not, then why try and cool it? An oil cooler requirement should be established from testing, not guessing.

 

why thankyou kind sir
does an oil cooler really cool oil i can't beleive that
would you really suggest a 130ps 2litre n/a cars oil cooling capabilitys would be sufficent for a 2ltre turbo with twice the power and a turbo generating 1.2/1.4 bar of boost? i'd be very suprises if it was and if i was doing the build i'd fit one as a precaution thats all i was saying

 

Put an oil temperature gauge on one and test it for yourself?

 

i would lol 3 of my lot have build zetec turbos nevery had an oil coooler lol pa_sjo knows his shit btw

 

just very suprised at that- did they take plenty of abuse with the oil temp not going through the roof?
from wot i've heard zetec turbos get very hot and breathe quite heavily so was just trying to help.
and i can see he knows his shit buts its a discussion forum is it not?

 

It sure is and I completely agree. I prefer to voice my opinion and don't like it when others back me up

Unfortunately i've had it driven into me over the years to test stuff myself, so now everyone else can get the benefit of that teaching

 

you bar steward, i best get testing then

 

i have a 1.8 engine and box form a focus for sale if your interested

 

yes one did over 6000 miles befor he sold the engine saying that it is still going and yet agan the other one had to be broke due to needing cash fast and well mines sitting in the garage

 

what sort of power can the zetec rods take? Im contemplating eagle items as they are pretty cheap from the states.... just wish the pound would get strong again!

Have heard they are good for many varying figures but thought id ask on here.

 

i would cap the power at 280 but ive heard (and only heard) the can go to 330

need to watch out with them rods from the US as they only use blacktop zetecs i think not to sure if they will fit a silver top.

 

ahh i see, well i wanna fit steel rods anyways as it will be peace of mind in the long run but may have to go for forged pistons too as the c20let sit too high on the eagle rods according to pa sjo

 

the eagle rods will fit in a silver top a black top and the st170 block

 

lovely! will the fit and work properley with c20let pistons, obviously need pin holes machining

 

how much are going to pay for the rods and machining??? i only payed Ł500 for my eagle rods and je pistons with arp bolts and all pins and rings.

 

where from mate?

 

was going to pay about 250 for rods and around 30 quid for machining plus 100 quid for c20let pistons

 

i got mine from here and only took 5 days to come.
