hey guys been thinking for a while to start a side project and use my old CVH engine (once rebuild) and put it into a mk6 escort gti, i used to own a mk6 and really liked the car it just needed to be quicker!

Anyways, i was speaking to ollie from here a few nights ago about doing this and i was wondering what needs to be done if i wanted to fit the CVH engine into a MK6 that came with a Zetec engine.

I know people will just say "go zetec turbo" but i already have a CVH engine sat here.

What needs to be done to the loom etc, do you just remove the zetec loom and fit a FRST OFAB ecu with the FRST CVH loom wired into the mk6 car loom?

cheers.

You may have the CHV "sitting there" but I think it would still be false economy to go through all the hastle of fitting it.

Dont forget the money/time spent on wiring adaptions and engine mounts and all the other little bits etc etc

Youd be better off selling the CHV and putting the money to something like some tasty bike carbs to strap on to your zetec

Would probably be quicker IMHO

Also another thought a modified (throttle bodied) original engine, will be far cheaper to insure than an RS turbo converted mk6 escort.

ok then so if you are both suggestions TB route - can you tell me what needs to be done to use the Throttle bodys and what power it makes?

GSXR 750 seem quite a common option.

The fiesta boys are quite upto date on TB's. lots of fez and escort mk5/6 zetec on here.

Here is a fitting guide using GSXR 1000 throttle bodies to a Zetec engine, mounting on an ST170 inlet manifold.

200+ BHP is not uncommon

1.9 xr2 on 40's

zvh it, efi head and frst managment, easy peasy and all bolt on if you have the oil return and breather in the sump

i thought a ZVH is a MFI head you use and then just use an EFI setup that correct?

1.9 xr2 on 40's

nah bang on an xr2i efi head (same as frst but cheaper) then its piss easy as you zetec big end has the cps already

you wont be running daft power on std big end but 15psi will be happy enough and theres plenty of grunt there too, big cooler required if you want to push it

best thing is it it goes pop fit another £50 engine and of you go again

i much pref doin a zvh with a good tinkered with head than rebuilding tired cvh's

Still got the insurance nightmare tho with this.

Id still go TB's, They are a piece of piss to put on a zetec, and far less worries in terms of something going wrong or reliability issues.

And in terms of BHP for your money (taking into account doing the modification and insuring it) I dont think you will get much better.

i used gixxer 650 tbs on my old mk6. easy enough and seen over 180bhp on a pooh map!

get some cams in there and a st170 manifold and you have a nice 200bhp!

Exactly, nice easy reliable.

Just think how much more problems there are gonna be with a zvh or cvh.

With the TB's its generally a one off mod, unlike a turbo conversion where your almost guranteed there will be plenty of future work and fucking around long after the conversion is actually "finished".

Sell the CVH engine and go have a look at Stu Occleshaw's old "Spec A" GTi Zetec Turbo. Was featured in an issue of Performance Ford about 3 years ago now. Was a brilliant car built as cheaply as a (well spec'd and reliable) Zetec Turbo could be.

im new to the tuning scene so sorry if im a bit slow but why can you not keep the zetec head and crankcase together if you are turbo-ing a car, so like a zetec turbo? as opposed to zvh

would this not make far more power, with it being four valves not two?
has anyone done it and how much would it cost?

yes you can, i have myself built a zetec turbo. some have just skimmed 1mmoff the pistons of a std 2.0l and ran low boost, but god enough for 250 bhp.

mine however, is a bit special and im hoping for over 400 lol

Lawrence101

so 250bhp but how much altogether cost wise tho?

Chris69

the problem with building a turbo is there are alot more things to consider so if you doing it DIY the T/B's is the way to go imo.
either that or keep it zetec and bolt a de-comp plate on the engine, you then have to buy a turbo -stage 2 T3 at least
an intercooler- frount mount really.
have your radiator adapted for watercooling if you want that.
all teh pipework and bits n bobs
oil return to sump
and loads of other little bits like oil coolers etc that may or may not be needed dependant on spec.
the T/B route is cheapest and easiest and sounds great
