Hi guys after much umming and arring about which engine to go for, and driving my mates 203bhp FRST i have decided a 200bhp engine would be acceptable for my needs as it is a nice useable power IMO.

I have decided to therefore go 2.1 ZVH turbo so i dont screw the life out of the cvh as i use the car hard daily and from what i have seen with my mates is they eat gearboxes and headgaskets .

What im trying to find out is what will be needed and what is missing from my list

So im assuming:

2.0 bottom end
Decomp plate?
do i remember something about a different cambelt pulley and sump?
Metal head gasket
Im on OFAB management already
Beige injectors and a 195 chip
i have a stage 2 t3 and big front mount which i beleive will be more then enough for the job, the main aim is to have reliable 200bhp without parts being on the limit all the time, yet still having the potential to up the power abit if i ever get bored in the future.

Anything i have missed/and or got wrong? and if anyone could let me know what pulley/sump i need to run would be very greatfull

Sump, oil pickup and dipstick off an 1800 zetec escort.
Std skimmed pistons if you dont want to run more than 14psi or forged if you do
1300 cvh cambelt tensioner, 1600 cvh bottom pulley
and get it setup properly
Thats what I used to build the 1800 bottom end that I ended up selling because I changed spec again Made decent power (about 240?) I believe after the lad who bought it got it setup and dynoed. Took 0.5mm off the top of std 1.8 silvertop pistons

loads of bumf on there, you can use c20xe or let pistons cant remember which.

I'd use the full zetec engine, decomp plate, adapters for the inlet and exhaust. Will do 200bhp, can still use your ecu

Adam.

Thats great thanks for the info mate, so i would need to skim the standard pistons regardless, and unless i want to run more then 14psi i cant use standard pistons.....

Only thing im thinking is with zetec, it seems people are spending alot of time and cash to get them where they want them and seem to be mainly trying to gain 300bhp ish when im literally after 200-230ish bhp, which as said IMO is more driveable.

It's Czech Mate

For 200bhp i'd save the hassle and get a nicely prepped cvh 1.6, plenty reliable at that power!

ZVH's can be horrible even when well specced and built.

If you're worried about breaking boxes then avoid the ZVH. High torque spikes that they produce are box breakers. It'd be easier to build a CVH for 200BHP than a ZVH anyway!

Being brutally honest if you're only wanting 200bhp mate that's very easily achievable staying with the 1.6 and as long as the engine's built by someone who knows what they're doing and more importantly is mapped properly it will be 100% reliable
Depending on the spec of the engine and what turbo you use you won't need to run mega boost either which might save your gearboxes

luke19790_3

Standard bottom in zetec will do 200bhp, head in good for 300.

It's Czech Mate

I'd get an unburstable spec cvh with aftermarket management with about 220 bhp and really decent boost control and map the boost so it won't over stress the gearbox. Will be a great car to thrash then

Buy Karlos G's bits and you'll have a strong reliable 1600cvh. No faffing about changine the engine details on the logbook that way

Rollinz

why not just buy a complete focus RS engine?

Adam.

Because i forgot to plant a money tree in the garden last year

Rollinz

you can pick them up for less than a ZVH conversion would cost!

Karlos G

All sold now other than the block, crank and inlet manifold! lol
But yeah for 200bhp a stock CVH is perfectly fine and wont get through gearbox's as said above.
All you need is a stage 2 T3 (.36/50) and an intercooler, job done

Adam.

I have a stage 2 t3 mate, and airtec stage 2 intercooler (60mm)
Just ordered a 195 chip and have the beiges allready so once the chips fitted i shall stick it on the rollers and see where we are on the cvh im running then

ontheway

No Way! a ZVH running about 200 brake would easily come in quite far south of 500 quid... and FRS engines change hands for significantly more than that minus manifolds and any ancillaries

Adam.

Agreed.

Rollinz

Ł500 for a ZVH build?? what u building it with?? chewing gum!

i built a ZVH,
what about having back of head welded up to use zetec gasket? or you guna use a cvh one?
what about pistons?? machine work
tensioner

for Ł500 its guna be a right nail of an engine!

So long as your CVH is healthy and there is nothing wrong with the old management you will easy break 200bhp then fella.
Oh would be worth sticking a set of ARP rod bolts in for peace of mind though.

Cost of engine Ł2300 plus. Ian Howell built this engine at area six

Not to be down on your post but just to point out those injectors will only flow for around 200bhp @ fly, it's impossible that they are flowing for 300bhp @ wheels mate.

For budget build use st170 bottom end with thick headgasket like felpro and sitech have a few built all running between 250/300bhp with no problems
You can buy a complete st170 engine around 500/600 quid.
Then the head will sell for half that , then the conversion bits are around Ł300 plus Ł120 worth of machine work.

You need to mod the sump, which crazycage has done,

Honestly mate i went zvh and always regretted it, just go full zetec turbo! you can spend half the money and see a much better bhp!!! if you only want 200bhp thats cool but take in mind a full zetec turbo will do 200bhp with ease... and for a lot longer then a zvh!
